The answer would be C 90% sure
Answer:
comparative anatomy
Explanation:
they both provide evidence for evolution homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor the structures are similar because they evolved to do the same. Not because they were inherited from a common ancestor
Answer:
Option B, The average number of food vacuoles formed in 30 min would decrease.
Explanation:
As we know ink solution act as a food source for the T vorax culture. The higher will is the amount of solution added, the higher will be the number of food vacuoles formed in a given time period.
Therefore, when 20 micro liter of ink solution is added instead of 100 micro liter of ink the food vacuole number will decrease.
Hence, option B is correct

Answer:
The correct answer is: Facilitated Diffusion.
Explanation:
- Facilitated Diffusion can be defined as the process by which certain solutes, molecules and substances are transported across the plasma membrane down their concentration gradient (from a region where their concentration is high to a region where their concentration is low) with the help of carrier proteins.
- Carrier proteins are trans-membrane integral membrane proteins, those remain interspersed in the lipid bilayer of the plasma membrane and spans across the entire length of the plasma membrane such that they open up both in the cell interior as well as the cell exterior.
- Polar molecules like glucose, charged ions, amino acids are transported across the membrane by the process of facilitated diffusion. This is because due to their charge the lipid bilayer is impermeable to allow their direct simple diffusion.
- The process takes place along the concentration gradient and so it does not require the expenditure of metabolic energy.
