Answer:
Explanation:Ss
Because
The gene snails of a population consists of all the copies of all the genes in that population.
The probability of two independent events occurring together is the Quotient of the probability of each event occurring separately.
Answer:
As a result of mitosis and meiosis, haploid and diploid cells are formed.
The cell will be diploid if it will have two sets of chromosomes, that is the number of chromosomes will be double than that of haploid one. And all the chromosome pairs in diploid are considered homologous chromosomes. e.g. the somatic cells of the body are diploid cells.
Haploid cells will be those who do not have chromosomes in pairs, a single set of chromosomes is found in them. e.g. the haploid spores or gametes cells. The chromosome number in haploid cells are represented as 'n'. Haploid cells are produced via meiosis in cell division.
When an environment is hypotonic, the cell has more solute, so solvent moves from outside the cell to inside, causing the cell to swell.
WHAT IS TONICITY:
- Tonicity refers to the ability of a solution to cause the inflow or outflow of water in a cell. Tonicity of a solution can either be: hypotonic, hypertonic or isotonic.
- Hypotonic: This is when a solution has less concentration of solute or more concentration of water than its surroundings.
- Hypertonic: This is when a solution has more concentration of solute or less concentration of water than its surroundings.
- Isotonic: This is when the solute concentration between a solution and a cell is balanced or equal.
Based on osmosis, which is the movement of water from a region of higher concentration to a region of lower concentration through a semipermeable membrane, water will move from a hypotonic environment into a cell containing more solute.
Therefore, When an environment is hypotonic, the cell has more solute, so solvent moves from outside the cell to inside, causing the cell to swell.

The troposphere is hotter near the Earth's surface because heat from the Earth warms this air. As the altitude increases the number of air molecules decreases, the average of their kinetic energy decreases.
Does this help?
