Explanation:
Antibodies have three main functions: 1) Antibodies are secreted into the blood and mucosa, where they bind to and inactivate foreign substances such as pathogens and toxins (neutralization). 2) Antibodies activate the complement system to destroy bacterial cells by lysis (punching holes in the cell wall).
It should be the last one, but if you can pick more than one answer then I would do the first and last one but I’m confident that it would be the last one either way :) hopefully this is helpful
The correct answer is 'If molecules are small enough, then they can pass through the semipermeable membrane because they can cross the semipermeable membrane from their small pores or openings'.
The semipermeable membrane is permeable to few molecules, and the smaller molecules pass through the molecules from small pores present in the semipermeable membrane. The size of the big molecules are large, so, they cannot cross through semipermeable membrane.
That is true. The movement of oceans has no impact on the earths climate.
This is possible by having different stem cells for different types of cells which then have different genes activated to make cells different
