During winter's freezing temperatures, some plants can remove water from their cells to reduce the amount of water that will freeze inside them. Why would plants need to do this
Answer:
The expansion of excess water as it turns to ice inside the cells would break the cells apart
Explanation:
We know that water expands anomalously. It expands between 4- 0°C.
Hence water expands upon freezing. Ice has more volume than liquid water and takes up more space in plant cells.
The expansion of excess water as it turns to ice inside the cells would break the cells apart

People spray pesticides on crops to kill insects that eat and destroy the crops. However, these insects are becoming resistant to the pesticides. Explain how this could happen.
When an organism or insect develops a mechanism for the removal of the pesticide compound is known as pesticide resistance.
What is pesticide resistance?The organism or insects develop mechanisms such as the alternation of the binding site of the compound present in the pesticide leading to the development of resistance against the used pesticides. The development of resistance against the pesticide is a slow process, it takes time. The usage of pesticides becomes a failure if organisms develop resistance.
The frequent use of pesticide and insecticides cause changes in the genetic material of the organisms. They help in the development of enzymes and changes in the binding sites. These changes are passed on to the next generation of the organism, which makes the entire population resistant to the particular pesticide and insecticide.
The use of the chemicals should be monitored. Only use when required with rotation.

what are the 7 factors of classification of living things
1 Nutrition
Living things take in materials from their surroundings that they
use for growth or to provide energy. Nutrition is the process by
which organisms obtain energy and raw materials from nutrients
such as proteins, carbohydrates and fats.
2 Respiration
Respiration is the release of energy from food substances in all
living cells. Living things break down food within their cells to
release energy for carrying out the following processes.
3 Movement
All living things move. It is very obvious that a leopard moves but
what about the thorn tree it sits in? Plants too move in various
different ways. The movement may be so slow that it is very
difficult to see.
4 Excretion
All living things excrete. As a result of the many chemical
reactions occurring in cells, they have to get rid of waste products
which might poison the cells. Excretion is defined as the removal of
toxic materials, the waste products of metabolism and substances
in excess from the body of an organism.
5 Growth
Growth is seen in all living things. It involves using food to
produce new cells. The permanent increase in cell number and size
is called growth.
6 Reproduction
All living organisms have the ability to produce offspring.
7 Sensitivity
All living things are able to sense and respond to stimuli around
them such as light, temperature, water, gravity and chemical
substances.

Is It possible for two parents with a round jaw to have a child with a square jaw? Why or Why not
Yeah it's possible. Even though both parents have round jaws... that may be the result of a dominant trait overpowering the recessive trait. As long as both parents have the recessive gene (in other words they're heterozygous traits) then there is a possibility for a child to be born with a square jaw.
Neurons transmit signals to the central nervous system. The brain processes this information to initiate a response. Two neurons communicate with each other through the

Vertebrates are complex animals, but they still share some characteristics with invertebrates. Mia volunteers at her city's aquarium for the summer. She likes observing the invertebrates. Which statement explains the pattern in the body structures of invertebrates, starting with the sponges and ending with echinoderms?
Answer: Their body structure becomes increasingly more complex.
Explanation:
In the classification of living things, all animals belongs to Kingdom Animalia. This is contains two main groups namely:
--> invertebrates and
--> Vertebrates.
The vertebrates are complex animals which are characterized with the presence of a backbone.
The invertebrates are less complex animals with no backbone. The phyla that exists in this group includes: porifera, coelenterata, platyhelminthes, nematodes,annelida, mollusca, arthropoda,echinodermata and many among others.
Their body structure becomes increasingly more complex from the phylum porifera to the phylum echinodermata. The Sponges are simple aquatic invertebrates that have ASYMMETRICAL BODIES (this makes them to lack specialised tissues that could prevent them from moving about). While the echinodermata have RADIALLY SYMMETRICAL body with body parts arranged around a central mouth and anus. They have a unique system of water canals for transport inside the body and numerous tube feet moving about.
What is the primary function of DNA replication in adult human somatic cells?
A to allow the cells to adapt to changes in the environment by generating new alleles of genes
B to generate multiple copies of genes the cell can use to increase protein production
c to prepare to create a new cell that contains the same genetic information
d to prepare the cell for meiosis to generate gametes
Answer:
B to generate multiple copies of genes the cell can use to increase protein production
Explanation:
Terms in this set (44) - Replication means that the DNA, with all its genes, must be copied every time a cell divides so that during growth and repair the newly formed cells have the correct genetic material.
How is it possible that the reactants and products for both chemical equations have the same quantity of carbon, hydrogen, and oxygen atoms, yet the reactants and products are different molecules?
Answer:
Yes, this may be a little confusing when taking a first glance at the chemical equation.
Explanation:
You see, the whole process of balancing an equation is to make sure the reactants and products have the same amount of mass/atoms.
With that being said, the products to appear to be different after going through the chemical change. this is because of what was happening through that process. But, all of these atoms are still within the final product.
For example, if you take water in a container, one with a lid and one without a lid, then you heat up both containers of water, the container that has the lid open will seem like the water is gone, that the atoms are not the same. Actually, if we take a look at the closed container, all of that gas that was formed from the water still has the same amount of atoms contained in it. As for the open lid container, the atoms are all there, but some of them was just released into the air outside of the jar, making it seem like there is less.
#teamtrees #WAP (Water And Plant)
The study of chemicals is called chemistry.
It is possible to have different chemical properties but the same number of elements present in the reactant and the product.
According to the law of mass of conservation of the mass. it states that the number of elements present in the reactant and the product will always remain the same.
Hence, according to this law, the mass and the quantity of the element are the same but the bonds and the arrangement of the elements are different which causes different chemical behavior.
Hence, it is possible.

Sickle cell anemia is carried on the recessive allele. Normal is dominant. Mary is a carrier for sickle cell and Mike is normal (but not a carrier).
A. What are the chances of Mary and Mike having a sickle cell child?
B. What are the chances of them having a child who is a carrier?
Answer:
A. 0
B. 1/2 or 50%
Explanation:
Let us assume that the sickle cell anemia trait is represented by s and the alternate normal version by S.
Mary, a carrier would have the genotype Ss.
Mike, a perfectly normal person would have the genotype SS.
If both Mary and Mike marry:
Ss x SS
offspring: SS SS Ss Ss
(A) In order to have sickle cell, the two alleles must be recessive. None of the offspring from the cross has two recessive alleles. Hence, the chances of Mary and Mike having a sickle cell child is zero.
(B) From the cross, two out of four of their potential offspring have the trait in heterozygous condition. Hence, the chances of Mike and Mary having a child who is a carrier is 1/2 or 50%.

Determine the temperature of the bar on the fahrenheit scale.
Answer:
Determining bar temperature on Fahrenheit scale -
The temperature of the bar is given as 50 degrees Celsius.
If we know the temperature on the Celsius scale, we can convert it to the Fahrenheit scale.
We know
C / 5 = (F-32) / 9; Where C is the temperature on the Celsius scale and F is the temperature on the Fahrenheit scale.
Now,
50/5 = (F-32) / 9
Or, (F-32) / 9 = 10
Or, F-32 = 90
Or, F = 90 + 32
Or, F = 112 degrees Fahrenheit.
That is, the temperature of the bar on the Fahrenheit scale is 112 degrees Fahrenheit
