Answer:
b) Channel pumps
Explanation:
The channels are the transmembrane proteins that serve in the passive transport of substances down the concentration gradient. The channels can be gated or non-gated. The gated channels are opened and closed in response to certain stimuli such as electrical change.
For example, aquaporins are the gated water channels that transport the water across the plasma membrane. The process is driven by the osmotic gradient and does not use the energy of ATP.
Binary fission is a type of asexual reproduction or rather an asexual reproduction common in most prokaryotes.
This function happens when the organism divides itself producing another replica of its genetic material and now altogether as the organism itself.

Answer:
d. vary and change for both males and females from culture to culture
Explanation:
Gender roles vary for both females and males across cultures. This can be observed in the way some societies are patriarchal and some are matriarchal. For example: in many Asian cultures, traditionally males head the families. It's their responsibility to engage in outside work and take important decisions for the family while women take care of household chores. This is reversed in some cultures like that present in Meghalaya, India. Here women are dominant figures in households. They inherit property, give their family name to children and after marriage the man comes to live with the woman's family. Hence gender roles are variable culture to culture.
