Answer 2

Pro phase is the starting stage of the division where the cell division begins. Spindle fibers  are broken into half and the type of division that is present in gametes is reduction division that is the meiosis. Synapsis occurs during mitosis.

What is synapsis ?

It is defined as the stage in which the pairing of the homologous chromosomes take place.

Chromosomes do not line at the equator as the lining of the chromosomes at the equator occurs on the stage of mitosis where it is possible to see the V,J and L shapes of the paired chromosomes. After this stage the exchange of genetic material takes place.Chromatin do not change into chromosomes in the metaphase.

Mitosis is present only to make the duplicate copies of the cell. The identical daughter cells are made when the division of mitosis is taking place in the cell. Chromosomes are first visible in the prophase. A centromere holds two sister chromatids together.

In meiosis crossing over takes place in anaphase 1.

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.

A compound that is formed as a common product of the process of photosynthesis is sugar (glucose).

What do you mean by Photosynthesis?

Photosynthesis may be defined as a process through which plants utilize carbon dioxide and convert it into glucose in the presence of sunlight.

The reactants of photosynthesis are carbon dioxide and water, while the products are glucose and oxygen.

The reaction of photosynthesis is given below:

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.

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.

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.
