I think its because so the plants can absorb more nutrients from the soil while being sturdy and wide so when the plant gets snowed on it doesn't break<span />

They have shallow, wide roots:
To cover as much ground as possible, so the plant can absorb a sufficient amount of water before it freezes, and because the permafrost prevents the plants roots from going further down into the ground.  <span />

During DNA replication, the leading strand is synthesized continuously, whereas the lagging strand is synthesized as Okazaki fra
Leokris [45]

Answer:

Because DNA polymerase can synthesize DNA strands in 5' to 3' direction only.

Explanation:

The 5' end of one DNA strand is present opposite to the 3' end of the other strand. But DNA polymerase enzyme can elongate the primers in 5' to 3' direction only. Formation of a phosphodiester bond between the existing nucleotide and the incoming nucleotide requires the free 3'OH. This 3' OH serves in the nucleophilic attack during the formation of the bond.

Therefore, the lagging strand is synthesized discontinuously in the form of short DNA fragments. These are called Okazaki fragments. Primers are formed for short distances which in turn are elongated by DNA polymerase to form the Okazaki fragments. On the other hand, the synthesis of the leading strand occurs continuously in the same direction in which the replication fork moves.

UkoKoshka [18]

Answer:

Option A, shared their data with colleagues to obtain feedback on the work.

Explanation:

All researchers prefer to share their findings with their peers or other researchers working in the same field to get their reviews. This step is very essential as it makes the research authentic and removes the flaws that would have otherwise missed by the researcher.  

Peer reviewers also give useful suggestion to further modify one’s research study based on their experiences.  

Hence, option A is correct

Do autotrophs need to perform cellular respiration?
nydimaria [60]
Many autotrophs make food through the process of photosynthesis, in which light energy from the sun is changed to chemical energy that is stored in glucose. All organisms use cellular respiration to break down glucose, release its energy, and make ATP. Autotrophs are also called producers. They produce food not only for themselves but for all other living things as well (which are known as consumers). This is why autotrophs form the basis of food chains.
Yes, autotrophs need to perform cellular respiration.

Answer:

Oxygen.

Explanation:

Oxygen molecule that is produced in the light dependent reactions. This shutting down of linear electron flow greatly affected the production of oxygen. Photosystem II gains replacement electrons from splitting of water molecules into hydrogen ions (H+) and oxygen atoms so if the electron flow is disturbed then oxygen production is greatly affected.
