Asexual reproduction does not produce variety in population, unless through mutations, because offspring are exact copies of their parent – because they reproduce by binary fission.
Explanation:
Sexual reproduction produces variations by genetic combinations. Remember during meiosis, there is the crossing over of chromosomes. In addition during fertilization, in sexual reproduction, each gamete brings in alternative forms of alleles of genes. The advantage of asexual reproduction is that it allows for fast reproduction because only one parent is involved in the formation of offspring.

Answer:
a deoxyribose (5-carbon sugar), a phosphate group, and a nitrogenous base (Figure 9.3). So the third option.
I think the correct answer from the choices listed above is option A. Both proteins and complex carbohydrates are polymers of smaller subunits. They <span>are substances whose molecules have high molar masses and are composed of a large number of repeating units.</span>
Yes, it is possible to develop effective vaccines for any type of viruses. Genetically engineered viruses exhibit similar characteristics to natural viruses.
<h3>What is a virus?</h3>
A virus is a genetically independent entity that needs a suitable host to reproduce its genetic material (either DNA or RNA).
A genetically engineered virus is a virus whose genetic material has been modified using genetic engineering techniques.
Vaccines can be developed for removing any type of viruses because they take advantage of the intrinsic properties of the immune system (i.e., antigen recognition), independently of its origin.

Answer:
A healthy ecosystem consists of native plant and animal populations interacting in balance with each other and nonliving things (for example, water and rocks). ... Decomposers break down dead plants and animals, returning vital nutrients to the soil. Plants take up these nutrients, along with water, through their roots.
