If a molecule of DNA has 32% guanine before DNA replication occurs, each new
molecule of DNA that is produced following replication will contain what percentage
thymine?

A) 64%
B) 32%
C) 18%
D) 36%

Answers

Answer 1

If DNA molecule has 32% G (guanine) then it would have the same % of C (Cytidine) since G pairs with C in a double stranded DNA molecule, that would be the same during semi conservative replication.

Rest of it would be divided in A (adenine) or T (thymine).

GC content of DNA varies bases on organism and species and therefore, AT content varies as well.

Hope this helps (this is not my answer)

Victor has been studying the vascular systems of plants. He wanted to find out if food coloring would travel up the stalk of celery faster if the temperature of the water increased. Victor set up his experiment with three cups of colored water at different temperatures, three equal sized celery stalks, and a stopwatch. Cup A was filled with colored water at 21 C. Cup B was filled with cold colored water at 4 C, and Cup C was filled with warm colored water at 30 C. One celery stalk was placed in each cup at the same time. Victor timed how long it took the colored water to travel to the leaves at the top of the celery stalk. He measured the time in minutes. What is the independent variable

Answers

Answer:

temperature

Explanation:

The independent variable would be the colored water at different temperatures.

The independent variables are changeable or controllable variables supplied directly by researchers in the course of experiments. They produce effects on the dependent variable and are thus referred to as the 'cause' variable. The dependent variables are referred to as the 'effect' variables because their values vary based on that of the independent variables.

In this case, the only controlled variable of all the variables supplied by Victor is the temperature of the colored water. Changing the temperature of the colored water is expected to have effects on the time it will take for the colored water to travel to up the stalk of celery. Hence, the temperature is considered as the independent variable while the time it takes for the colored water to travel to the leave would be the dependent variable.

Genes A and B are neutral. A weakly beneficial mutation arises in the population. This mutation is 100 base pairs away from Gene A and 1000 base pairs away from Gene B. If this mutation were to go to fixation within the population, which gene would be more likely to go to fixation and what is the term for this process? Is there any reason to suspect that one or both of these genes may not go to fixation? Why or why not?

Answers

Answer:

Both genes would be likely to go to fixationThe term for this process is "linked genes"The reason to suspect that both of these genes may not go to fixation is that they are too close to the mutation and the recombination frequency between them is very very low.

Explanation:

Independent assortment law establishes that the alleles from two or more different genes distribute in gametes independently from each other. In other words, a gamete receives an allele from a gene that does not depend nor influence the allele of another gene in the same gamete. This can only be applied to independent genes. These genes segregate independently after crossing-over because they are located far away from each other.

Some other genes, however, are too close to each other and they do not segregate independently. These are the linked genes that do not exhibit an independent distribution, and they inherit together more frequently.  

Crossing-over between linked genes that are very close to each other in the chromosome is not that common. Crossing-over during meiosis occurs randomly in different positions all along the chromosome, and its occurrence frequency in the area between two genes depends on the distance between them. A short distance between genes is a very little target for crossing-over to occur, which means that only a few of them will happen, compared with the number of events between genes that are more separated between each other.  

Two genes that are very close will have a few recombination events and are strongly bounded.  

The more separated two genes are, the more chances of recombination there will be.  The closer they are, the fewer chances of recombination there will be.

Genes that express 50% of recombination frequency or more are not linked genes.  

To analyze the recombination frequency, we have to know that

1% of recombination = 1 map unit = 1centi Morgan = 1,000,000 base pairs.

And that the maximum recombination frequency is always 50%.  

The map unit is the distance between the pair of genes for which every 100 meiotic products one of them results in a recombinant one.  

In the exposed example we know that the distance of gene A from the mutation is 100 base pairs, and the distance of gene B from the mutation is 1000 base pairs.

1,000,000 base pairs ------------------ 1% recombination frequency

1000 base pairs -----------------------X = 0.001% recombination frequency

100 base pairs ------------------------ X = 0.0001% recombination frequency

According to the recombination frequency between the mutation and gene A, and between the mutation and gene B, we can assume that both genes are linked to the mutation, as they seem to be too close to it. They are so close, that their recombination frequency is very little.

list five different system interactions for the topic of acid rain

Answers

Answer:

1. Effects of Acid Rain on Fish and Wildlife

The ecological effects of acid rain are most clearly seen in aquatic environments, such as streams, lakes, and marshes where it can be harmful to fish and other wildlife. As it flows through the soil, acidic rain water can leach aluminum from soil clay particles and then flow into streams and lakes.

2. Effects of Acid Rain on Plants and Trees

Dead or dying trees are a common sight in areas affected by acid rain. Acid rain leaches aluminum from the soil.  That aluminum may be harmful to plants as well as animals. Acid rain also removes minerals and nutrients from the soil that trees need to grow.

3. Buffering Capacity

Many forests, streams, and lakes that experience acid rain don’t suffer effects because the soil in those areas can buffer the acid rain by neutralizing the acidity in the rainwater flowing through it. The soil becomes thin because of this and lacks the ability to adequately neutralize the acid in the rain water. As a result, these areas are particularly vulnerable and the acid and aluminum can accumulate in the soil, streams, or lakes.

4. Episodic Acidification

Melting snow and heavy rain downpours can result in what is known as episodic acidification. This can result in short-term stress on the ecosystem where a variety of organisms or species may be injured or killed.

5. Nitrogen Pollution

It’s not just the acidity of acid rain that can cause problems. Acid rain also contains nitrogen, and this can have an impact on some ecosystems. For example, nitrogen pollution in our coastal waters is partially responsible for declining fish and shellfish populations in some areas. In addition to agriculture and wastewater, much of the nitrogen produced by human activity that reaches coastal waters comes from the atmosphere.

Explanation:

Not sure if this is what the question was asking for.

Acid rain is defined as rain or any other kind of precipitation that is particularly acidic, including high quantities of hydrogen ions. Acid rain has a pH lower than drinking water, ranging from 4-5 on average.

What are the different system interactions for acid rain ?

1. Acid Rain's Impact on Fish and Wildlife

Acid rain's biological consequences are most visible in aquatic areas such as streams, lakes, and marshes, where it can affect fish and other species. Acidic rain water can drain aluminum from soil clay particles as it passes through the soil and into streams and lakes.

2. Acid Rain's Effects on Plants and Trees

In acid rain-affected locations, dead or dying trees are prevalent. Aluminum is leached from the soil by acid rain. Aluminum may be damaging to both plants and animals. Acid rain also depletes the soil of minerals and nutrients required by trees to develop.



3. Capacity for Buffering

Many woods, streams, and lakes that experience acid rain remain unaffected because the soil in such locations can buffer the acidity in the precipitation flowing through it. As a result, the soil becomes thin and unable to effectively neutralize the acid in the rain water. As a result, these locations are more sensitive, and the acid and aluminum can build up in the soil, streams, and lakes.


4. Acidification on Occasional Basis

Melting snow and strong rain can cause a condition known as episodic acidification. This can cause short-term stress in the environment, injuring or killing a range of creatures or species.

5. Nitrogen Pollution

Not only may the acidity of acid rain cause difficulties. Acid rain includes nitrogen, which can have an influence on some ecosystems. Nitrogen contamination in our coastal waterways, for example, is partly to blame for dwindling fish and shellfish populations in some locations. Aside from agriculture and sewerage, much of the nitrogen created by human activities that reaches coastal waterways originates in the atmosphere.

The knee ________.
a. is completely enclosed by a strong articular capsule
b. is a multiaxial joint
c. has ligaments present inside as well as surrounding the articular capsule
d. is the simplest joint in the body

Answers

Answer:

The correct answer is: C) has ligaments present inside as well as surrounding the articular capsule.

Explanation:

The knee joint is a hinge (ginglymus) type synovial joint that is formed by three different bones: the femur, the tibia, and the patella.

Given the nature of the hinge joint, it should only allow flexion and extension, but it also grants a small degree of internal and external rotation. For this reason, the knee joint cannot be considered a multiaxial joint, since it only fully moves in one axis and slightly moves in a second one (this is why most people consider the knee joint a uniaxial joint, but some others say it is actually a biaxial one).

The knee joint isn't completely enclosed by a strong articular capsule. The knee joint is rather thin and it contains the patella, menisci, bursae, and ligaments of the knee.

The knee is not the simplest joint in the body. It is formed by three bones and there's also the menisci, which are fibrocartilaginous structures that help increase the stability of the joint and act as shock absorbers as well.

The knee does have ligaments both inside and outside the articular capsule. The intracapsular ligaments are two cruciate ligaments (one anterior and one posterior), which hold the tibia in place; the transverse ligament that connects both menisci; and the posterior and anterior meniscofemoral ligaments. The extracapsular ligaments are the patellar ligaments (connects the patella to the tibia), the two collateral ligaments (medial and fibular, one on each side of the knee, connecting the femur to the tibia and to the fibula, respectively), and the anterolateral ligament.

What does speed mean?

Speed is defined as the distance that is allegedly covered in a given amount of time. It is regarded as the speed at which anything is said to move.

In this instance, speed is estimated as 1/2mv2.

As a result, the variables for calculation are:

If the bottle is moving at 2 m/s, then

= ½ (0.250) (2) ^2

= 0.5

If the bottle is moving at 3 m/s,

= ½ (0.250) (3) ^2

=1.125

If the bottle is moving at 4 m/s, then

= ½ (0.250) (4) ^2.

= 2

If the bottle is moving at 5 m/s, then

= ½ (0.250) (5) ^2

= 3.125

= ½ (0.250)(6)^2

=4.5

Therefore, It is regarded as the speed at which anything is said to move.

Color blindness is a recessive X-linked trait. A normal couple has a color-blind child. At least one member of the couple's families is colorblind, who is this most likely to be?a) the child's paternal grandmotherb) the child's paternal grandmother or grandfatherc) the child's maternal grandmotherd) the child's paternal grandfathere) the child's maternal grandfather

Answers

Answer:

c or e

Explanation:

The correct answer would be the child's maternal grandmother or grandfather.

For X-linked traits, only females can be carriers while males are either affected or totally free from the trait. This is because females have two X (XX) chromosomes while males have only one (XY).

Since the couple is normal, it means the father is free from color blindness. The only available option now is the mother and since she is phenotypically normal, it means that she is a carrier of the disease. She must have inherited the allele from either of her parents, but not from both. If she had inherited an affected X chromosome from each of her parents, she would have been phenotypically affected for color blindness.

Hence, the child's color-blind allele can only be traced back to either of the child's maternal grandmother or grandfather.

The correct option is c or e.

The member of the couple's family who is this most likely to be colorblind is the child's maternal grandfather.

An X-linked recessive inherited genetic trait is transmitted from parent to child through mutations in genes localized on the X chromosome.

In males, X-linked recessive traits are always expressed because males contain only one X chromosome.

In consequence, in this case, the mother should be a normal carrier of the disease/condition, thereby her dominant X-linked allele can mask the expression of the recessive (daltonic) allele, which is passed to the child from the maternal grandfather.

In conclusion, the member of the couple's family who is this most likely to be colorblind is the child's maternal grandfather.

Suppose you want to investigate what kind of material is best for making a warm winter coat. How could you use a freezer, a thermometer, and samples of materials to find an answer?

Answers

Answer:

By designing an experiment where the temperature on the thermometer is measured after a chosen (same) time interval when the thermometer is wrapped with the different  materials and placed in the freezer

Explanation:

Experimental design

Materials given: freezer, a thermometer, samples of materials

setup:

1. The freezer is put on and made to remain at a particular temperature, mimicking the winter season.

2. Next, different materials for the coat design with equal dimensions are used to rap the thermometer whose initial temperature has been recorded in the same pattern and the thermometer is placed in the freezer and left for a certain time, which is made constant for the different materials.

3. after the time, the final temperature on the thermometer is recorded.

Result interpretation

The temperature is expected to drop after the time in the freezer, but the material with the smaller change (drop) in temperature indicates that it traps more heat hence is the best material for designing a winter coat

independent variables: type of material used

dependent variables: temperature on the thermometer

control variables: time, dimensions of materials, temperature of freezer, pattern of wrapping.
