Answer: Membrane transport proteins are specific and selective for the molecules they move, and they often use energy to catalyze passage. Also, these proteins transport some nutrients against the concentration gradient, which requires additional energy.
Explanation:
When energy passes from one trophic level to the next, I would guess that the two factors which decrease the total amount of energy from being passed up are:
1. An organism does not assimilate all the energy of food consumed. Within a consumer, digestion and assimilation of energy is not 100% efficient: some of the energy is lost.
2. A large proportion of energy assimilated by a producer and consumer is lost through respiration, i.e., day-to-day maintenance of metabolic processes.

Answer:
Basal cells, keratinocyte
Explanation:
The viral DNA replication is inhibited until<u> Basal cells</u> are differentiated into <u>keratinocyte</u>, which are ready to be shed from the epithelial layer, increasing the likelihood that HPV will be transmitted to a new host.
95% of the cells in the epidermis are keratinocytes
Basal cells are multipotent stem cells that are important in the regeneration of homeostasis of the respiratory epithelial cell population.
in skin growth, most of the cells are keratinocytes and they are formed by the division of stem cells in the basal layer
