Endocytosis is the process by which Bulky Molecules enter the cell.
Explanation:
- Endocytosis is the process by which eukaryotic cells take up large molecules into their cytoplasm.
- The large molecules that cannot enter the cell through protein channels of the plasma membrane are carried into the cell in membrane bound vessicles.
- The vessicles are formed by progressive invagination of the cell membrane and then pinching off after the molecule is trapped.
- Endocytosis has been classified as phagocytosis (cell eating) and pinnocytosis(cell drinking).
Channel protein is important because it is embedded in the membrane and it also covers the membrane. This is important because the channel must transport the micromolecules and ions in and out of the cell. Carrier proteins are important because the carrier must transport the molecule in and out of the cell.
The producers would grow more food to be eaten but the secondary/tertiary etc consumers would have nothing to eat and so numbers would drop on that side
Answer:
a. All of these
Explanation:
<em>The characteristic of skin that makes it unpleasant for most bacteria would be due to all of the conditions.</em>
Most bacteria require humid condition in order to grow and as such, the desiccated nature of the normal human skin makes it difficult for them to establish themselves and grow on it.
The pH of the skin is usually acidic due to the production of lactic acid during sweating and the activities of the normal skin bacteria. The acidic pH hinders the growth of bacteria that can potentially become pathogenic to the skin.
Also, the skin produce antimicrobial substances at low pH which hinders the growth of pathogenic bacteria.
Hence, options b, c, and d are correct.
It’s RR. Homo is the same and hetero is mixed. (I hope I remember right)
