<span>Meiosis in simple terms is the process by which gametes (sperm and egg) fuse together to produce a fertilised egg. Haploid is a word that refers to how many chromosomes a certain cell has. In this case the gametes have a haploid number of chromosomes, which is half the number a normal cell has. A normal cell has a diploid number of chromosomes. So in meiosis the two gametes come together with their hapoid number of chromosomes each to create an egg that has a diploid (standard) number of chromosomes.</span>
The correct answer is option (D) The active transport and the facilitated diffusion both involve the proteins present in the cell membrane.
Facilitated diffusion transport the large and the charged molecules through the protein transport channels present in the cell membrane. In this case, the solute move from a region of higher concentration to lower concentration and it does not require energy.
Active transports takes place when the molecules move from a region of lower concentration to higher concentration via the membrane protein channels.
Both facilitated diffusion and active transport requires the proteins present in the cell membrane.
The answer is A) Carbon
Hope this helps.
lemon juice is 100 times as acidic as tomato juice. remember, each step in the pH scale represents a change in concentration by a factor of 10. since tomato juice has a pH of 4.0, and lemon juice has a pH of 2.0, the concentration would change by 10 times 10.
