Organisms are constantly interacting with their environment. Sometimes this interaction has a positive effect on the environment

, other times a negative impact. Beetles in the forest infest and eat limbs of trees that have fallen to the forest floor. The best way to describe the beetles impact is to say that
A) they are having a neutral impact on the environment by acting as decomposers.

B) they are having a positive impact on the environment by acting as decomposers.

C) they are having a negative impact on the environment by acting as decomposers.

D) they are having a predatory impact on the environment by acting as decomposers.

The correct answer is option B) i.e. they are having a positive impact on the environment by acting as decomposers.

By acting as decomposers beetles are helping in recycling of nutrients between biotic (organisms) and abiotic factors (enviroment). So, it may be considered as positive impact on the environment. Decomposers play a very important role in food chains and food webs. They breakdown biomolecules and liberate the micronutrients and micronutrients as inorganic molecules back to the environment. These inorganic molecules are used by plants once again  to synthesize biomolecules. This is how nutrient cycle operates with the help of decomposers. For example, protein molecules of dead and decaying matter are broken down by decomposers to liberate nitrogen gas to the environment which is utilized by leguminous plants to make protein molecules again.

erastova [34]

The sets of alleles for each parent are Dm for the mother and DM, Dm, dM, and dm for the father. This information is fundamental for estimating genotype and allele frequencies in offspring.

<h3>What are alleles?</h3>

Alleles are gene variants for a given gene <em>locus</em>, diploid organisms inherit two alleles for each locus (one from each parent).

Gametes are germinal (haploid) cells that carry specific allele combinations.

The analysis of gamete combinations is fundamental to estimate genotypes and allele frequencies.

Which mechanism decreases the number of genetic variations in a population? A. founder's effect B. mutation C. gene flow
Georgia [21]
<span>The correct option is A. Founder's effect is the reduced genetic variability that occur as a result of population production from a small number of colonizing parents. The founder's effects is one of the ways by which nature can randomly produce new species from existing population.</span>

According to the Punnett square, 4/16       plants will have red flowers and green seeds.

So, (4 ÷16) × 100 = 25% chance of obtaining offspring with red flower and green seed.
