That would be the chloroplasts. keep in mind that chloroplasts have their own dna,which also indicates that they were once independent organisms that were engulfed by another bigger prokaryote (endosymbiosis). you will probably need to know that later on, so i hope that helps u in the future :)

Provide the term for base triplets on tRNA
Semmy [17]
The answer is anticodon.

Anticodons are base triplets on transfer RNA (tRNA). t<span>RNA carries amino acids to the ribosome for protein synthesis. </span>The prefix<em> anti-</em> suggests that anticodons are complementary to the codons on mRNA. Codons are base triplets on mRNA. So, anticodons of tRNA pair with codons of mRNA in the process of protein synthesis.

Infer why it is more difficult to make an antiviral drug that fights a virus that replicates through the lysogenic cycle than it
jekas [21]

Answer:

In the lysogenic cycle, the viral genome gets incorporated into the host genome and replicates with the host genome. In the lysogenic cycle, no proteins and enzymes of the virus are formed while in the lytic cycle protein of viral capsid form and new phages generate in the host cell.

So as the viral genome integrates into the host genome in the lysogenic cycle, therefore, it is difficult for any drug to differentially act on the viral genome. So there are great chances for drugs to target the host genome in the host cell.  

But in virus that replicates through lytic cycle drugs can selectively act on viral enzyme and proteins. Therefore it is difficult to make a drug that affects lysogenic virus.

Read the following passage and construct a flow chart by matching the following events with their proper sequence. Physical exer
blsea [12.9K]

Answer:

Person starts to exercise.

Skeletal muscle oxygen demand increase  

Skeletal muscle metabolism increases

.Blood delivery to the skeletal muscle increases is order to provide more oxygen  

Oxygen sensors cause local blood cell vessels to dilate

.

This steps briefly describe the physiology of exercise.

At the onset of exercise,  skeletal muscles cells were sustained with  available oxygen from the Myoglobin. Myoglobin is  oxygen binding and storage  protein found in cardiac and skeletal muscles cells.  it has high storing capacity for oxygen.

However as the exercise becomes intense ATPs supply drops, oxygen  demand increases,cellular metabolisms demand also increase to supply glucose and ATP to the cells.

The liver mediates Gluconeogenesis.  Fatty acid is broken down to glucose for cellular respiration  with' ketone bodies  build up..Exercise also stimulates the breakdown of muscle glycogen to glucose,  Therefore, cellular respiration takes place to break down the glucose to  C02, H20  and energy with rise in temperature.

However, oxygen concentration is  low, therefore muscles cells undergo anaerobic respiration with lactic acid pathway. Lactic  acid  build up in muscles cells.The muscles cells under go oxygen debt to break down  lactic acid  to glucose in muscle.

Therefore to adjust the mechanism oxygen homeostatic sensors increases hyperventilation to increase  oxygen intake through the lungs, and vasodilation. so that maximum volume of blood containing oxygen is transported to muscles cells; to sustain the intense activity
