DNA profiling is a forensic technique in criminal investigations, comparing criminal suspects' profiles to DNA evidence so as to assess the likelihood of their involvement in the crime. It is also used in parentage testing, to establish immigration eligibility, and in genealogical and medical research. DNA profiling has also been used in the study of animal and plant populations in the fields of zoology, botany, and agriculture.
Answer: A
Explanation: The majority of diseases are spread by bodily contact, microbes, and items. While it is true that some diseases are passed down through heredity, this fact is not used in court.
how is digestion related to cellular respiration.
Answer:
The digestive system breaks down the food into molecules. The cells then convert those molecules into a form of energy they can use. When you breathe out, you get rid of the carbon dioxide that your cells produce during cellular respiration.
A student drew the following diagram to model the structure of a prairie
community. Which level represents short and tall grasses?
A. Level 2
B. Level 1
C. Level 4
D. Level 3
Answer: B. Level 1
Explanation:
The prairie community is dominated by the grass and vegetation cover. Thus the lower most trophic level in the prairie ecosystem are the short and tall grasses. They produce major source of biomass for the herbivores of the food chain. They consume the grasses can be designated as primary consumers of the food chain. Also the producers which are grasses which make up the large amount of biomass will provide a source of food for the consumers. They will receive 100 percent energy from the sun and they will utilize 90 percent of it to make their food by the process of photosynthesis. Only ten percent of energy is transferred to the next trophic level.
Answer:
B level 1
Explanation:
Photosynthesis and cellular respiration both involve the Jews and release of gases was semi-correct identifies the role of gases in the two process?
Answer:
Photosynthesis and cellular respiration both are opposite to each other.
Explanation:
Photosynthesis and cellular respiration both are opposite to each other because the reactants of photosynthesis are the products of respiration whereas the reactant of respiration are the products of photosynthesis. In photosynthesis, carbondioxide gas react with water forming oxygen and glucose while on the other hand, in respiration, glucose is broken down with the help of oxygen produces carbondioxide gas, water and energy in the form of ATP.

difference between hormones and enzymes
1. Enzyme act at the same place as origin while hormones travel from one place to another via blood.
2. Enzymes are biological catalyst while hormones are not.
.3 All enzymes are protein in nature while hormones can be polypeptides, steroids, terpenoid or amines.
4. Enzymes can be reused in a chemical reaction while hormones cannot.
Answer: One of the major differences between enzymes and hormones is that enzymes act as a catalyst for a reaction and hormones act as messengers that trigger various functions in the body.

Cells within multicellular organisms are specialized to perform specific tasks. What is one advantage of specialized cells? A. Specialized cells use more energy than nonspecialized cells. B. Specialized cells are slower than nonspecialized cells. C. Specialized cells are able to perform a greater variety of tasks than nonspecialized cells. D. Specialized cells are more efficient than nonspecialized cells. pls answer asap i need it.
Answer:
Specialized cells are more efficient than nonspecialized cells
Explanation:
Multicellular organisms are organisms with more than one cells i.e. multiple cells. This characteristics of multicellular cells makes it possible for cells to specialize into performing different functions.
Cells within multicellular organisms are specialized to perform specific tasks. What is one advantage of specialized cells? A.

What two factors cause the Gulf Stream to move away from the equator?
Answer:
The Gulf Stream is caused by a large system of circular currents and powerful winds, called an oceanic gyre.
As the warm water comes in, colder, denser water sinks and begins moving south—eventually flowing along the bottom of the ocean all the way to Antarctica.

Describe the prairie dog's niche. How does it find shelter and impact the environment?
Answer:
1.His niche is to dig burrows in grassy plains. It has an impact on the environment because sometimes animals have the same niche and this could unleash competition and the decrease of some populations. 2.By digging up the soil and exposing it to air, as well as burying bones and food, dogs help renew and enrich the environment. But mostly they just don't want Buster, the sneaky neighbor dog, to get their treasured item.
Explanation:
Answer:
In addition to providing food and shelter to associated species, prairie dog burrows actually enrich the soil and improve vegetation quality because water concentration is able to flow underground. Prairie dogs prefer to create their homes in overgrazed areas so the low vegetation can provide protection from predators.
Explanation:
How is protein synthesis related to mutations?
what is the job of the carrier protein in the cell membrane
Answer:
Carrier proteins move materials from one side of the cell membrane to the other. This is useful for both active transport, meaning you have to transport against the concentration gradient, and facilitated diffusion, a form of passive transport.
If an organism was able to survive the increase in airborne toxins, what traits will their offspring carry? What about the next generation?
Answer:
If an organism is able to survive the increase in airborne toxins and reproduce, there is a high chance that their offspring will also be able survive in airborne toxins, although some may not. But all the organisms that can survive and reproduce will produce more and more organisms that are able to survive from an increase in airborne toxins.

Explanation: It is younger because it retains most of its potassium. This means that the potassium has not had time to break down yet. In the second rock there is little to none of it's original potassium. Meaning it has existed long enough for most of the potassium to break down.
HELP 80 POINTS IF U ANSWER + BRAINLIST!!!
How does your model show what happened to the circled rock material as a result of plate motion?
Answer:
Once exposed, they are weathered, both physically (by mechanical breaking of the rock) and chemically (by weathering of the minerals), and the weathering products — mostly small rock and mineral fragments — are eroded, transported, and then deposited as sediments. Therefore, the model should show signs of deterioration and subduction.
Explanation:
I'm not sure if this is on a quiz or test, but this is what I would put down. No need to mark me brainliest, thanks anyway! :)
