Answer:
The increase in the amount of carbon dioxide in in blood will lead to respiratory acidosis
Explanation:
Carbon dioxide in its normal level between 38 to 42 mm Hg plays vital roles in the human body like regulating the PH of the human blood, breathing regulation and other things. If the amount of carbon dioxide is high more than the range level, it will cause what is called respiratory acidosis.
Respiratory acidosis is a situation in cause by decrease in ventilation i.e Oxygen level leading to increase in carbon dioxide and drop in PH level of the blood.
Answer:
<em>The tyres of car wear out gradually, due to the frictional force. Frictional force arises between two objects when they move over one another. In the given cases it arises between the tyre and the surface which it is travelling on.</em>
Answer;
A) Blood pressure decreases greatly; blood flow to the heart is inadequate, and blood pressure decreases.
Explanation;
-With negative feedback, the output reduces the original effect of the stimulus. While in a positive feedback system, the output enhances the original stimulus.
-Negative feedback is the most commonly used feedback loop in the body. Negative feedback is used to negate or counteract a stimulus without completely eradicating it.
-One key difference between the two feedback is that positive feedback loops are used to eradicate a stimulus. Another key difference is that responses through positive feedback become more amplified over time. So once a stimulus activates a positive feedback loop it is not turned off until the stimulus is completely removed.

Answer:
<h2>A site for the exit of the diphosphates removed from the nucleotide triphosphates.</h2>
Explanation:
Transcription occurs in three steps, i) initiation, ii) elongation, and iii) termination.
Elongation: during elongation , the RNA polymerase add new nucleotides in the growing chain of RNA molecule until it encounter terminator factor, or until it terminate transcription. RNA polymerase has three prominent channels, i) channel for entry of DNA template strand, ii) channel for exit of DNA strand and iii) channel for exit of newly synthesized RNA molecule. There are lots of other enzymes which helps in transcription.
