Pulmonary arteries transport ________.

Biology
1 answer:
andrezito [222]2 years ago
3 0

Answer:

B

Explanation:

I would say this because the pulmonary circulation only transports deoxygenated blood. And this blood gets transported to the lungs so the lungs can absorb oxygen and release carbon dioxide. I am not sure about this one though. This is what I think.

What happens to RNA polymerase II after it has completed transcription of a gene? a. It begins transcribing the next gene on the
Over [174]

The correct answer is: b. It is free to bind to another promoter and begin transcription

Transcription is the first step of gene expression in which DNA molecule is copied (transcribed) into RNA (mRNA) by RNA polymerase. The process of transcription is divided into three phases:

1. Initiation

• RNA polymerase with transcriptional factors bind to gene promoter  

• RNA polymerase unwinds DNA double helix (transcription bubble is formed)

2. Elongation

• RNA polymerases adds nucleotides complementary to DNA  

3. Termination

• RNA polymerase gets to stop codon (transcribes a sequence of DNA known as a terminator)

• Formed complementary RNA strand is released from DNA-RNA complex.

RNA polymerase is also released and can transcribe some other gene by binding to its promotor. RNA polymerase will transcribe just the genes whose products are needed at a particular moment.

Answer:

Both aerobic and anaerobic respiration.

Explanation:

Glycolysis may be defined as the process of break down of glucose molecules for the formation pf ATP with the help of enzymes and chemical factors. Glycolysis occurs in the cytosol of the organism.

Glycolysis may occur in the presence of organism known as aerobic respiration. The glycolysis can occur in the absence of oxygen as well known as anaerobic respiration. The steps involved up to the formation of pyruvate molecule from the glucose is same in case of aerobic and anaerobic respiration.
