Answer:

c)Recruit the transcription factors and RNA Polymerase that compose the pre-initiation complex.

Explanation:

Transcription leads to formation of RNA from DNA. The process is carried out by RNA Polymerase which forms a RNA strand according to the template DNA strand.

It starts by the formation of pre-initiation complex. RNA Polymerase along with transcription factors binds to the promoter region of DNA and forms the pre-initiation complex. Generally the eukaryotic promoters have a sequence called as TATA box where the transcription factors bind first. Eventually RNA polymerase also binds to the region and the DNA strands separate starting the transcription process.

To make new cells, humans undergo a process of cell division called mitosis. Before a cell goes through cell division (mitosis),

sashaice [31]

Before a cell goes through cell division (mitosis), it must grow and make a copy of its DNA which is termed as an Inter-phase.

Explanation:

Some tasks must be carried out by the cells before they undergo division: The cell must grow, it must copy the genetic material (DNA) present in it, and divide into two daughter cells. These steps carried out by cells are termed as cell cycle.

Cells that contains a nucleus or Eukaryota cells, there are two major phases called interphase and the mitotic (M) phase. that comprises the cell cycle.

In inter-phase, growth of the cell and making a copy of its DNA is carried out.

In mitotic (M) phase, the cell separation of the DNA in the cell into two sets and division of its cytoplasm takes place resulting in the formation of two new cells.

What happens to a carbon atom transitioning between photosynthesis and respiration?

sukhopar [10]

The carbon dioxide that is,CO2 is split into carbon and oxygen ,the some of the oxygen is released and the carbon is mixed with water that is H20,the product is glucose(sugar)
that is why we say that during photosynthesis plants take in water and carbon dioxide in order to manufacture their food(which is glucose) and to release oxygen

Regular aerobic exercise training affects carbohydrate (CHO) usage by ____. Select one: a. increasing the enzymatic activity ass

VladimirAG [237]

Answer:

Option B, increasing the number and size of mitochondria

Explanation:

Mitochondria (power house of a cell) produce energy. When no exercise is done, the productivity of mitochondria reduces but it increases with regular exercise. In fact aerobic training helps mitochondria in making more energy by enhancing its efficiency. With one cycle of exercise, mitochondria produce 32 ATPs. Aerobic exercise allows more of oxygen to get to the muscle cells, the faster it happens the more energy is produced

Hence, option B is correct

What type of disorder is sickle cell anemia? A.recessive B.lung C.dominant

Tom [10]

Answer:

A Recessive

Explanation:

Generally, there are two types of disorders, progressive and recessive. When something is recessive, it is not a dominant gene. The reason why sickle cell anemia is classified as a recessive disorder is because it only affects some people, but it does not affect all those who share DNA. Hope this helps!
