There would be 10 centromeres at the g2 phase of cell cycle.
The cell cycle is process by which a cell produces a new similar daughter cell. it composes of two main phases These are called the interphase and m-phase. The interphase has three key stages which are gap 1, s phase and gap 2. And the M-phase is where the cell itself divides with an equal number of chromosomes.
Answer:
The correct answers to the question are:
- The concentration of solute bathing the inner side of the plant cell membrane should be high.
- The concentration of solute bathing the outer side of the plant cell membrane should be low.
Explanation:
- Turgidity can be defined as a condition in which the cell membrane of the plants cells becomes completely extended as a result of which it pushes tightly against the cell wall.
- This happens when the cell takes up water from its environment and stores it in the vacuoles.
- Water enters to the inside of the cell by the process of Osmosis.
- Osmosis can be defined as the process by which molecules tend to move or diffuse from a region where its concentration is high to another region where its concentration is low, provided the two regions are separated by a semi-permeable membrane.
- In any region, the concentration of solute and and concentration of solvent bears an inverse relationship. This means that the region where the solute concentration is high, the solvent concentration is low and where the solute concentration is low, the solvent concentration is high.
- In the given question, as the cell takes up water from the surrounding into its vacuole to become turgid, so by the concept of osmosis, the concentration of water must have been high outside the cell and low inside the cell.
- Again by the inverse concentration concept of solute and solvent, the concentration of solute inside the cell should be more than the concentration of solute outside the cell.
Answer:
A) Chromosomes are made of DNA
C) Alleles are the different forms of a gene that can exist
D) Chromosomes contain genes that control the inheritance of traits.
Explanation:
Chromosomes are long molecules of deoxyribonucleic acid (DNA) that contain part (or all) of the genetic material of an organism. Humans contain 46 chromosomes organized in 23 pairs of homologous chromosomes (22 pairs of autosomal chromosomes and one pair of sex chromosomes, X and Y). Moreover, a gene is a physical segment of a chromosome that contains the information to encode a protein. Alleles are different forms of a gene (i.e., gene variants) that may be caused by mutations or genetic recombination. Humans are diploid organisms (2N: 46), and therefore we have two copies of each gene (alleles), one on each homologous chromosome.
