Cells produce granules that secrete a lipid-rich product that make the skin waterproof

keratinocytes

Explanation:

The skin contains various types of cells like melanocytes, keratinocytes and Langerhans cells. The Keratinocytes constitute about 90% of the human skin and are mostly present in the basal skin.

The keratinocytes produce keratin protein which protects the skin and some keratinocytes contain keratohyalin granules which are filled with cysteine-rich and histidine-rich proteins. The keratin and these granules make the skin waterproof.

Thus, keratinocytes are the correct answer.

the cell cycle is the final answer! : )

succession returns a disturbed

ecosystem to a more stable state. this is also classified into two (2) types:

primary succession and secondary succession. the primary succession arises when

a new land is transformed and a bare rock has been exposed providing an environment

that can be occupied for the first time. while, secondary succession occurs

when a previously occupied environment was disturbed that kills much of all its

community
