Cell membrane function
Marina86 [1]

Scattered in the lipid bilayer are cholesterol molecules, which help to keep the membrane fluid consistent. Membrane proteins are important for transporting substances across the cell membrane. They can also function as enzymes or receptors. On the extracellular fluid side of a cell membrane, you find carbohydrates.

The yellow ring inside the bacterial cell represents the bacterial DNA. Why does this structure disappear by step 3 of the lytic
adell [148]

Answer:

The bacterial DNA gets degraded at step 3 of the viral lytic cycle.

Explanation:

Viruses are organisms that are incapable of replicating on their own, hence, they require a living host which they infect and use its replicational ability to reproduce theirselves. The infection cycle of this virus is regarded as its replication cycle. Viruses employ either the LYTIC or LYSOGENIC cycle for infection.

The lytic cycle involves killing of their host cell at the end of the cycle. Generally, the cycle starts with the attachment of my the virus to the cell membrane of its host using specific receptor sites (step 1). It then penetrates the host cell as seen in step 2.

After penetration, the virus then secretes certain degrading enzymes called ENDONUCLEASES that degrades the bacterial DNA. After which the virus uses the replicational and gene expressing ability of the host to transcibe its genetic material and replicate itself. This process called SYNTHESIS occurs in step 3.

Hence, the yellow ring in the image that represents bacterial DNA disappears in step 3 (synthesis stage) because it gets degraded by viral digesting enzymes.

A 2-day-old infant who weighs 6 lb (2722 g) is fed formula every 4 hours. newborns require about 73 ml of fluid per pound (454 g
Tcecarenko [31]
The answer would be 72.94 ml/times

In this problem, the infant is fed for every 4 hours. Then, the frequency of feeding for a day would be: (24hours/day) / 4 (hours/times)= 6 times/ day.
The volume of feeding for a day that the infant need would be: 2722 g/(<span>454 g/73ml)= 473.68ml
The number of milk for every fed would be: (</span>473.68ml/day)/ (6 times/day)=  72.94 ml/times

Why does a lot of rain form over West Ferris?​
Semmy [17]

Answer:

This idea helps explain why more rain forms over West Ferris than East Ferris.Therefore, when explain that water vapor condenses higher in the atmosphere, they are actually explaining that water vapor condenses high in the troposphere, which is relatively low in the atmosphere.
