Answer:

a. the RNA polymerase undergoes abortive initiation prior to promoter clearance

Explanation:

In eukaryotes the 3' end of the mRNA is polyadenylated to protect the mRNA from degradation.

In eukaryotes, a modified guanine cap is added to the 5' end of the mRNAd to protects the transcript from being broken down.

Most bacterial RNA transcripts do not undergo splicing.

The nucleosome is the basic unit of chromatin repeat in eukaryotes.

This is part of the autonomic nervous system that functions to conserve body resources and maintain homeostasis ("rest and diges
denpristay [2]

Answer:

Parasympathetic nervous system

Explanation:

The parasympathetic nervous system of the autonomic nervous system is activated to restore the body's energy level after the emergency conditions. This division of the autonomic nervous system triggers the digestion and absorption of nutrients so that body cells obtain and conserve energy.

Some of the responses generated by activated parasympathetic division are increased activity of glands associated with the digestive system and increased the contraction of smooth muscles of the digestive tract. The parasympathetic nervous system also slows down the responses required for physical activities such as heart rate and breathing rate.

The energy required to run the Calvin cycle reactions of photosynthesis comes from which two substances produced during the ligh
Lelu [443]

Answer:

a. ATP and NADPH

Explanation:

Light-dependent reactions of photosynthesis include splitting of water in the presence of sunlight and release of electrons. The electrons move from the reaction center of the PS-II via electron carriers to the PS-I. From the reaction center of PS-I, the electrons finally reach NADP reductase and reduce NADP into NADPH.

During this electron transfer via electron carriers, a proton concentration gradient is generated across the thylakoid membrane. The energy of this gradient is used to drive ATP synthesis. ATP and NADPH formed during the light-dependent phase of photosynthesis are then used during the reactions of the Calvin cycle.

what is the texture and appearance of the potato strips after being immersed in various concentration of sucrose solution​
Alexxx [7]

This process is a technique of osmosis. Osmosis is the movement of solvent particles. For example,  water along its concentration gradient, from high to low concentration, via a semi-permeable membrane is changing the structure of the molecules in the potato strips.  

Since the environment of the potato strips are in a sugar concentrate, the potato will lose its water content and so loses weight and the strips will be thinner and dryer.

ancestors of giraffes with shorter necks could not reach branches high up in trees for food. this led to selection for longer-ne
hichkok12 [17]

With shorter necks, giraffe ancestors could not reach food-containing branches on tall trees. This resulted in the directional selection of giraffes with longer necks.

 

<h3>Why is choosing a direction necessary? </h3>

It nearly appears obvious that the giraffe's long neck developed as a result of a lack of food in the lower branches of trees. The giraffe has a significant advantage because it is taller than any other mammal and can feed where few others can. 

When compared to modern giraffes, the giraffe's ancient predecessors had a shorter neck. The plants that were lying at a higher level were inaccessible to them. Giraffe phenotypes have changed in various ways, and now have long necks to reach vegetation that is higher up. The extreme form is chosen above other features in directional selection. It was decided to choose the long-necked giraffe over the short-necked.
