DNA evidence analysis is an imperfect science. Provide two reasons why this may be the case.
For my Biomedical Science Class
Answer:
Not all DNA that was found at the scene has to be related to the scene.
Explanation:
Just because DNA was found at the scene, that doesn't mean that the person there is actually guilty. For example, in a case where person B is guilty, a strand of hair from Person A could be carried over to another scene on Persons B's clothing.
Answer:
Because DNA is more reliable than other forensics, scientists have shrugged off suggestions that it could fall victim to the vagaries of bias. But Dror noted that much DNA analysis involves interpretation. With interpretation comes subjectivity, and with subjectivity can come error. Only one-tenth of 1 percent of human DNA differs from one individual to the next and, although estimates vary, studies suggest that forensic DNA analysis is roughly 95 percent accurate.

a
Cells move sugar into their cells with energy
Water moves from where there is more water to where there is less
b
с
Salt moves from a 15% solution to a 2% solution
d
Dye moves from where it is dropped throughout an entire glass of water
Answer:
с ) Salt moves from a 15% solution to a 2% solution
Explanation:
In active transport, the particles move across a cell membrane from a lower concentration to a higher concentration. Active transport is the energy-requiring process of pumping molecules and ions across membranes "uphill" - against a concentration gradient.Aug 14, 2020

Why are there two sets of phases during meiosis, but only one during mitosis? Think about what is different about meiosis and mitosis
Answer correctly or I will report
Answer:
Cells undergoing mitosis just divide once because they are forming two new genetically identical cells where as in meiosis cells require two sets of divisions because they need to make the cell a haploid cell which only has half of the total number of chromosomes.

Why are plants, but not animals, thought to be an important factor in classifying a land biome?
Answer:
becuase plants make up surrounding areas, if you see no plants and soil with no fertilization from plants it is most likely a desert, and a place with tall and thick plants is most likely a forest
Answer:
Explanation: Because the biome must support the plant since the grow a plant you must have good temperature the constant rainfall and the soil, that is why plants are the most important factor since its chooses what plant can survive in that biome.

Special chemicals that recognize and attach to germs are called what?
A. Antibodies
B. Red blood cells
C. Pathogens
Special chemicals that recognize and attach to germs are called Antibodies. Thus, the correct option is A.
What is Antibody?An antibody may be characterized as a protein produced by plasma cells in response to a specific antigen.
The major function of an antibody is to eliminate disease-causing organisms which are known as pathogens or any other external germs and barricade them from contaminating human cells.
Such antibodies after synthesis attach to germs or digested antigenic particles and then mediated the process of eliminating all such foreign particles.
Therefore, special chemicals that recognize and attach to germs are called Antibodies. Thus, the correct option is A.

Set of 25 green plants and 25 mushrooms were put in a cool, dark room for two weeks. Each set was watered daily with 50 mL of a 0.1% fertilizer solution. Which statement best explains why the green plants died and the mushrooms survived?
Answer:
This question lacks options, however, it can be answered based on general understanding.
The green plant died because of absence of LIGHT
Explanation:
Plants (green) are autotrophic organisms i.e. organisms that are capable of synthesizing their own food via a process called PHOTOSYNTHESIS. However, on the other hand, mushrooms (kingdom FUNGI) are heterotrophic organisms i.e. rely on other organisms for energy source and cannot make their own food.
Green plants strictly require light energy from the sun in order to perform the process of photosynthesis. According to this question, a set of 25 green plants and 25 mushrooms were put in a cool, dark room for two weeks and watered daily with 50 mL of a 0.1% fertilizer solution. The green plants, despite the nutrients and regular watering dies because they were not exposed to LIGHT in order to make their food via photosynthesis. However, since light is not a requirement for mushrooms to obtain food, they will surely survive.

Based on the graph in Figure 2, identify the environmental conditions (flower density AND proportion of deep flowers) where a short- tongued bee has the greatest relative advantage over a long tongued bee. Based on the graph in Figure 2, identify the range of proportion of deep flowers at which a long tongued- bee always has an advantage over a short tongued bee.
Answer:
The correct answer would be - low flower density and low deep flower proportion
Explanation:
To find the environmental conditions for a short-tongued bee has the greatest relative advantage over long-tongued bees it is required to find the highest value of relative advantage short-tongued bees has on long-tongued bees which is the point where flower density and deep flower proportion is lowest (near the zero) according to the graph. That is represented in the graph by the peak in the white shaded portion.
To find the range of deep flower proportion at which a long-tongued bee has an advantage take a closer look to the grey shaded area where if the deep flower proportion move from 0.6 to 1 the advantage of long-tongued bees over short-tongued.
Floral density with the graph shows the low flower density and low deep flower proportion. Floral density often influences the species composition of flower visitors.
This variation in visitor species composition has significant effects on pollination success and plant fitness, poorly understood, especially in the many pollination guilds dominated by non-territorial species.
How do flower visitors diverse the traits?It explores how flower visitors with diverse traits should distribute themselves across resource patches differing in floral density.
The model predicts that species with low flower search speeds and low flower handling costs compared to competitors will usually dominate dense flower patches.
In addition, amongst flower visitors that have lower energy expenditure rates while handling flowers than while traveling, species maximizing energetic efficiency are associated with dense flower patches.
Therefore, the correct answer is low flower density and low deep flower proportion.

Cellular respiration is a process in which animal cells use ____ taken in from the atmosphere.
1) carbon dioxide
2) hydrogen
3) oxygen
Answer:
How does cellular respiration work in animals?
When an animal breathes, it takes in oxygen gas and releases carbon dioxide gas into the atmosphere. This carbon dioxide is a waste product produced by the animal's cells during cellular respiration. Cellular respiration occurs in the individual cells. Digested foods have chemical energy stored in them.
Explanation:
What are two ways in which cells use the energy temporarily stored in ATP?
Answer: Energy provided by ATP is used in active transport, to contract muscles, to make proteins, and in many other ways
The two main ways in which cells use the energy temporarily stored in the form of ATP is in active transport, and to make proteins.
What is Active transport?
Active transport is the movement of molecules, ions, solutes, solvents against the concentration gradient. The flow of material takes place from the region of their lower concentration to the region of their higher concentration. The transport is against the gradient and hence requires energy to proceed which is given by ATP.
ATP is required to synthesize proteins in the ribosomes of the cell through the process of translation. This is a highly energy-consuming energy and thus required large amount of ATP.
