Epistasis Is Observed When The Allele Of One Gene Masks The Effects Of Another Gene. Use The Punnett

Answers

Answer 1

Answer:

The color of a dog's fur with the genes aabb would be yellow. So, in other words, Option A is correct.

Hope this helped :D Happy holidays! :D

Answer 2

Epistasis is the effect or character appear due to the interaction between genes. Here, the alleles responsible for the color of dog's fur show epistasis and the progeny with (aabb) genotype will show white colored fur. Thus, the correct option is D.

What is Epistasis?

Epistasis is also known as gene masking, where the expression of one gene is modified or masked or suppressed by the expression of another gene or more other genes. In this, more than one gene controls a specific character such as fur color, etc.

Epistasis is of different types such as dominant epistasis, recessive epistasis depending upon the effect of genes.

Here, the progenies with AABB genotype show black colored fur, the progeny with Aabb show brown colored fur, the progeny with genotype aaBB show yellow colored fur, and therefore, the progeny with genotype aabb i.e., both the recessive genes will show white colored dog fur.

Therefore, the correct option is D.

Answers

(D) is the right answer ........

Uncontrolled population growth affect the soil fertility and soil erosion i.e. it decreases soil fertility and increases soil erosion.

what is uncontrolled population growth?

uncontrolled population growth  is the area where the proportion of urban population has increased faster than the nation's average rate of population growth.

what is soil erosion ?

soil erosion is a gradual process that occurs when the impact of water or wind detaches and removes soil particles, causing the soil to deteriorate.

what is soil fertility ?

soil fertility is the ability of a soil to sustain plant growth by providing essential plant nutrients and favorable chemical, physical, and biological characteristics as a habitat for plant growth.

The population increases so that the demand for food increases, lack of arable land leads to intensive cultivation, reclamation to expand cultivation land on sloping hills increases soil erosion, causes degradation, infertile soil.

Therefore, use of chemical fertilizers and plant protection chemicals makes land resources, surface water sources of the mainland contaminated.

Reclamation makes area of ​​forestland narrowed, depletion of natural resources, natural environment polluted.

Answers

Answer:Plants

Plants, algae, and a group of bacteria called cyanobacteria are the only organisms capable of performing photosynthesis (Figure 1). Because they use light to manufacture their own food, they are called photoautotrophs (literally, “self-feeders using light”).

Explanation:

Answer:

All plants with green leaves, from the tiniest mosses to towering fir trees, synthesize, or create, their own food through photosynthesis. Algae, phytoplankton, and some bacteria also perform photosynthesis. Some rare autotrophs produce food through a process called chemosynthesis, rather than through photosynthesis.

Which is NOT
involved with an
inflammatory
response?
A. fever - increased temperature
B. slowed blood flow
C. white blood cells move to the area of infection
D. inflammation in area

Answers

Out of the given answers B. slowed blood flow is not involved with an inflammatory response.

During an inflammatory response, several physiological changes occur in the body to combat infection or injury. Let's briefly discuss the other options to understand their involvement in the inflammatory response:

A. Fever - increased temperature: Fever is a common feature of an inflammatory response. It is caused by the release of certain chemicals called pyrogens that act on the hypothalamus in the brain, raising the body's temperature. The increased temperature helps to enhance the immune response and inhibit the growth of certain pathogens.

C. White blood cells move to the area of infection: Inflammation triggers the recruitment of white blood cells, such as neutrophils and macrophages, to the site of infection or injury. These immune cells play a crucial role in identifying and eliminating pathogens, as well as removing damaged tissue and promoting tissue repair.

D. Inflammation in the area: Inflammation is a hallmark of the inflammatory response. It involves localized redness, swelling, heat, and pain at the site of infection or injury. Inflammation helps to isolate the area, prevent the spread of infection, and promote healing.

B. Slowed blood flow: Slowed blood flow is not a characteristic of the inflammatory response. On the contrary, inflammation often leads to increased blood flow in the affected area, resulting in redness and heat. The increased blood flow facilitates the delivery of immune cells, oxygen, and nutrients to the site, aiding in the immune response and tissue repair.

In conclusion, slowed blood flow is not involved in the inflammatory response, while the other options (fever, white blood cell recruitment, and inflammation) are key components of the inflammatory process. Therefore, the correct answer is B.

In 350 words explain what effects forest fires have on the environment while its burning and how it effects people and animals in the area.​

Answers

Wildfires release large amounts of carbon dioxide, black carbon, brown carbon, and ozone precursors into the atmosphere. These emissions affect radia]on, clouds, and climate on regional and even global scales. Wildfires Affect Air Quality.As fires burn, carbon stored in trees and other vegetation combusts, releasing carbon dioxide and other potent greenhouse gases such as methane and nitrous oxide into the atmosphere. This means that as fires increase, so do emissions.Wildfires emit carbon dioxide and other greenhouse gases that will continue to warm the planet well into the future. They damage forests that would otherwise remove CO2 from the air. And they inject soot and other aerosols into the atmosphere, with complex effects on warming and cooling.

To be sure, the leading cause of global warming remains overwhelmingly the burning of fossil fuels. That warming lengthens the fire season, drying and heating the forests. In turn, blazes like those scorching areas across the Northern Hemisphere this summer have a feedback effect—a vicious cycle when the results of warming produce yet more warming

Coronary heart disease is the main cause of death in our country. The following factors can increase the risk of an individual contracting this disease:

Explain how these factors can contribute to coronary heart disease.​

Smoking :-

The coronary arteries inside us are responsible for supplying our heart muscles with O₂ rich blood. When people smoke, plaque builds up in the arteries & the O₂ rich blood will not get supplied to the hear muscles causing atherosclerosis / coronary heart disease.

Unbalanced Diet :-

Eating an unhealthy diet which is high in cholesterol & fats also causes atherosclerosis (coronary heart disease). Too much salt in the diet can also raise blood pressure which is another factor responsible for this disease.

Unhealthy Lifestyle :-

Unhealthy lifestyles like not exercising at all & being obese lead to atherosclerosis (coronary heart disease).
