1. The oxygen requirements of an animal cannot be met by the process of diffusion as diffusion is a very slow process. To overcome this, multicellular organisms have specialized cells and tissues for performing various necessary functions of the body such as intake of oxygen and food.
2. What criteria do we use to decide whether something is alive? Any visible movement such as walking, breathing, or growing is generally used to decide whether something is alive or not. However, a living organism can also have movements, which are not visible to the naked eye.
3. An organism uses outside raw materials mostly in the form of food and oxygen. The raw materials required by an organism can be quite varied depending on the complexity of the organism and its environment.
4. The various processes essential for maintaining life are nutrition, respiration, transportation, excretion, control and coordination.

D phytoplankton i believe
be slower at absorbing nutrients than the other cell
Explanation:
The cell without the microvilli will be expected to have as slower absorption rate of nutrient than the other cell.
- Microvilli are finger-like projections from the surface of the cell.
- The structure has a large surface area to volume ratio which allows for nutrient to be absorbed easily.
- These structures are very important during the absorption of digested food in cells.
Cells without this structure will not absorb food faster.

Answer:
Explanation:
During transcription, DNA is converted into RNA in the nucleus of the cell.
Answer:
Plasma membrane is the semi-permeable membrane that allow the movement of some selected particles only against the concentration gradient or along the concentration gradient.
Different substances can be move through the diffusion, active process and passive process. The hydrogen in the vesicle has been moved through the facilitated diffusion. In this process, the hydrogen ions will move along the concentration gradient without the requirement of energy but requires the channel protein for its transport.
