What happen when the process of meiosis does not takes place?

If there has no process of meiosis takes place chromosome number will be doubled disturbing the genetic make up of the organism. If no meiosis has been takes place then the resulting of the zygote will be of double the number of the chromosomes. The genetic makeup would change entirely. The process of the meiosis halves the number of chromosomes in haploid cell and maintain the serenity of organism.

The process of the meiosis due to crossing over, genetic variation occurs which let the offspring receive favourable alleles to survive in new conditions and in the diploid organisms first the gametes are formed, then fertilization occurs and the diploid cell has  formed which gives rise to the organism having diploid cells.

Therefore, Two populations live in the same habitat and compete for food. The first group has larger and multiplies through asexual reproduction the second reproduces sexually an environmental change that causes the larger but unadaptable species to die off.

In other words, matter doesn't change into a different substance in a physical change. ... Changes of state—for example, from solid to liquid or from liquid to gas—are also physical changes. Some of the processes that cause physical changes include cutting, bending, dissolving, freezing, boiling, and melting.

Answer:

A) Evolution occurred because the allele frequency changed over time.

C) The rabbits with mottled brown fur have a selective advantage that gives them more camouflage from predators.

E) The mutation had a positive effect, allowing those rabbits with the mottled brown fur to survive and reproduce better than those with the brown or white fur.

Explanation:

Based on the data, you can conclude:

Evolution occurred because the allele frequency changed over time.

The rabbits with mottled brown fur have a selective advantage that gives them more camouflage from predators.

The mutation had a positive effect, allowing those rabbits with the mottled brown fur to survive and reproduce better than those with the brown or white fur.

Which of the following is the function of nucleic acids?
A. Breakdown chemical compounds
B. Carry heredity information
C. Structural support
D. Short-term energy storage

Answers

Answer:

B. Carry heredity information

Explanation:

Nucleic acids are one of the four types of biological molecules in nature. The other three being: proteins, carbohydrates, lipids. Nucleic acids consists of Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA).

DNA is a nucleic acid found in the NUCLEUS of eukaryotic cells or nucleoid region of prokaryotic cells where it functions to store or hold genetic information for the cell. On the other hand, RNA functions to carry the stored information in order to be expressed. Hence, according to this question, the nucleic acid functions to carry heredity information.

The possible allele combinations from the gametes of an organism with the genotype of AaBb is AB, Ab, aB, and ab. The correct option is D.

What are alleles?

Alleles are variations of the gene. The offspring contain genes or traits from both parents. The same trait is given by both parents, one become dominant and one become recessive.

A gamete is a haploid cell that fuses with another cell to produce offspring, This occurs during fertilization. The female gamete is called ova or egg, or male cells are sperms.

When the genotype that will be produced by the fusion of AaBb is AB, Ab, aB, and ab. The small letters denote the recessive gene and the capital letter denotes the dominant genes.

Thus, the correct option is D. AB, Ab, aB, and ab.
