Answer:
The two factors are:
• The kind/type of surface involved.
• The force that the surface are being pushed together.
Explanation:
Friction can be said to be the general term used to describe the force that one surface exert on another when they rub against each other.
When the surface is partially not smooth or totally rough, a greater force is been needed to move one surface past the other.
The weight of the can also significantly be a key factor. This is where the need to friction reduction come to play a role; and need for friction reducers like lubricant, rollers etc helps.
Some objects in space are created from clouds of gas and dust. A star forms when the mass of the dust cloud is large and has enough hydrogen to start creating a protostar and sustain the nuclear fusion reaction within the core of the protostar. If the dust cloud is not dense enough, then the star formation does not take place, rather a nebula is formed, example the Horse-head nebula. So the answer is (B) A star will not form.

Explanation:
Answer:
The whitefish embryo is a good place to look at mitosis because these cells are rapidly dividing as the fish embryo is growing. ... This is why mitosis is only visible in cells that are dividing, like the whitefish embryo and the onion root tip. Mitosis can take several hours to complete.
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
