Answer:

A scanning electron microscope provides much better resolution than a compound light microscope.

Explanation:

The electron microscope uses a beam of electrons and heavy particle like gold for resolution. A compound light microscope works by using light beams and lenses.

The resolution of electron microscope is smaller then the compound microscope. This means that more smaller parts of the specimen can be seen by the electron microscope.

The magnification power of electron microscope is far better then the compound microscope. Hence, a more bigger image can bee seen through the electron microscope.

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

Mammals like caribou that live in the arctic often use different lipid types in their legs. Legs are more susceptible to heat lo
motikmotik

1. The lipid would be more saturated. FALSE

2. The lipids on the fatty acid tails would be much shorter. TRUE

3. The membranes would contain more cholesterol. TRUE

<u>Explanation:</u>

The mammal caribou lives I the extremely cold environment of the Arctic and thus has several physiological adaptations to survive the cold. They have short ears to reduce heat loss and have two layers of fur. The lipids in caribou legs have several adaptations

When compared with saturated fatty acids unsaturated fatty acids are more fluid at low temperatures. Thus the lipids in the legs of caribou are unsaturated to maintain fluid nature at low temperatures of the Arctic. Shorter lipids on fatty acid tails remain more fluid at low temperatures when compared with the longer ones.  

Thus the lipid in the fatty acid tails will be shorter. Similarly the presence of more cholesterol in the membranes would make it more fluid in the cold conditions of the external environment. Thus the membranes would have more cholesterol.
