Viruses could pass through bacterial filter which made belief that viruses are fluid.
<h3><u>Explanation</u>:</h3>
Contagium vivum fluidum is the term that was used by the scientists to describe the virus. The virus was first discovered by the scientist Beijernick who isolated the tobacco mosaic virus and as the tried to filter and separate the virus through the finest of the filters possible, he couldn't. So he said that virus are fluid in nature. Later Ivanovsky also gave the same postulate. He crystallized the virus too.
But only after the invention of electron microscope, the structure and composition of virus were completely known.
Answer:
B) Polymerases can only synthesize in the 5' to 3' direction
Explanation:
The leading strand's directionality is 3' to 5', so polymerase has no problem with replicating this one. But the lagging strand has the opposite directionality, so the polymerase must work in the opposite direction of the replication fork.In consequence, the replication process undergoes periodic breaks, and the enzymes have to stop and start again while helicase separates both strands, resulting in the polymerization of okazaki fragments.
Answer:
Carbon cycle is the process where carbon compounds are interchanged among the biosphere, geosphere, pedosphere, hydrosphere, and atmosphere of the earth.
1) Carbon present in the atmosphere is absorbed by plants for photosynthesis.
2) These plants are then consumed by animals and carbon gets bioaccumulated into their bodies.
3) These animals and plants eventually die, and upon decomposing, carbon is released back into the atmosphere.
4) Some of the carbon that is not released back into the atmosphere eventually become fossil fuels.
5)These fossil fuels are then used for man-made activities, which pumps more carbon back into the atmosphere.
Carbon in the atmosphere is present in the form of carbon dioxide. Carbon enters the atmosphere through natural processes such as respiration and industrial applications such as burning fossil fuels.
It’s c
Because velocity; just like speed will be distance over time
However on this case it’s displacement over time
Anyway in case ur wondering ,
the only difference between distance and displacement is that displacement requires a direction
so
100m/4s
=25 m/s to the east since the direction is already mentioned in question
