The statement "Glycogen is a carbohydrate, and insulin is a protein" correctly identifies the types of macromolecules that are described. Thus, the correct option is D.

The main function of glycogen is to control the release of glucose into the blood when the condition is glucose deficient. It is the liver that directly contributes to the release of glucose into the blood.

Insulin is a hormone that is made up of amino acids, hence it is a small protein that contains almost all structural features of proteins.

Glycogen is a complex carbohydrate that can easily and rapidly coverts the form of glucose into energy.

Therefore, the correct option for this question is D.

Answer: D. 0.34

Explanation:

The Hardy-Weinberg Principle is a theory in biology that represents populations of organisms that don't experience any changes in genotypic frequency from generation to generation. These populations must meet the following conditions:

If a population meets these criteria, its genetic and allelic frequencies will remain constant and the population will be in Hardy-Weinberg Equilibrium. However, it is not possible for this to occur in nature, because at least one condition will always be violated in natural populations.

There are two important equations to use when doing problems like this. The first is p + q = 1. It represents the allelic frequency of the population.

The second equation is p² + 2pq + q² = 1, which shows the predicted frequencies of the three possible genotypes.

44 of our 100 organisms are green, and we know that to be green, they must have a homozygous recessive genotype (gg). That means that the frequency of homozygous recessives (q²) = 44/100 or 0.44. Since we have q², we can just take the square root to find q.

[tex]\sqrt{q^2}[/tex]= [tex]\sqrt{0.44}[/tex]

q = 0.66

Now, we can plug q into our first equation, p + q = 1.

p + 0.663 = 1

p = 0.337, or about 0.34

To make sure these are right, we can plug them into the Hardy-Weinberg equation to check!

p² + 2pq + q² = 1

(0.34)² + 2(0.34)(0.66) + (0.66)² = 1

0.1156 + 0.4488 + 0.4356 = 1

1 = 1

Use of bioagent is a good way to eliminate invasive species from an ecosystem.

In my opinion, to eliminate the invasive species from an ecosystem we should find out its bioagent instead of chemical spraying because bioagent does not adversely affected the environment.

The risks of the gene drive getting into another species are not worth gaining biodiversity in an ecosystem because it leads to many consequences and unpredictable effects on ecosystem.

So we can conclude that use of bioagent is a good way to eliminate invasive species from an ecosystem.

Yes, it is a good way to eliminate invasive species from an ecosystem. This is because invasive species play a critical role in the limitation of biodiversity of a particular ecosystem.

Biodiversity may be defined as the sum total of all the variety of living organisms in a particular ecosystem.

No, the risks of the gene drive getting into another species are not worth gaining biodiversity in an ecosystem. This is because it directs considerable influences and unanticipated impacts on the ecosystem.

Answer:

b

Explanation:

Droughts that are more frequent and severe, storms, heat waves, rising sea levels, melting glaciers, and warming oceans can all hurt animals, ruin their habitats, and disrupt people's livelihoods and societies.

Long-term increases in the earth's average surface temperature, as well as large-scale changes in global, regional, and local weather patterns, are caused by a considerable increase in the levels of greenhouse gases created by the burning of fossil fuels.

Dangerous weather events are growing more common and severe as climate change progresses.

Glacier melting occurs as a result of heat changes, particularly at relatively high temperatures. This is a process in which ice transforms from solid to liquid or water. Scientists have recently detected an alarming rate of glacier melting.

Unusually hot days and multi-day heat waves are a natural component of the weather's day-to-day fluctuations. Hotter-than-usual days and nights are becoming more prevalent as the Earth's temperature warms (see the High and Low Temperatures indicator), and heat waves are anticipated to grow more often and intense.
