If humans had been present to build log structures during the Carboniferous period (though they were not!), which plant types wo
aliina [53]

Answer:

The plant types suitable during that period would be ferns, horsetails, and lycopods.

Explanation:

A geologic period and system, which covers 60 million years from the termination of the Devonian period to the start of the Permian period is known as the Carboniferous period. During the Carboniferous period, the plant life was luxuriant and extensive, mainly at the time of Pennsylvanian. It comprises ferns and fernlike trees, that is, the giant horsetails known as club mosses, calamites, or lycopods like Sigillaria and Lepidodendron.  

Thus, if humans had been present to construct log structures during the Carboniferous period, then they would have used logs of ferns, horsetails, and lycopods for construction work.

Roman55 [17]

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
