<u>Answer:</u>
Angle of inclination is the independent variable.
Distance covered by the rolling ball is the dependent variable.
<u>Explanation:</u>
An independent variable is the one whose variation is not dependent on the value of any other variable while dependent variable changes its value with a change in the independent variable.
In this experiment, angle of inclination (angle between a line and the x-axis) is an independent variable whereas the the distance covered by the rolling ball is a dependent variable which will vary with a change in angle of inclination.
Hyperpolarization is a change in a cell's membrane potential that makes it more negative. It is the opposite of a depolarization. It inhibits action potentials by increasing the stimulus required to move the membrane potential to the action potential threshold.
Explanation:
Answer:
Within double-stranded DNA, the nitrogenous bases on one strand pair with complementary bases along the other strand; in particular, A always pairs with T, and C always pairs with G. Then, during DNA replication, the two strands in the double helix separate.
Explanation:
The four nitrogenous bases of DNA are thymine, adenine, guanine, and cytosine. Guanine and cytosine are bound together by three hydrogen bonds; whereas, adenine and thymine are bound together by two hydrogen bonds. This is known as complementary base pairing.
Answer:
Weeks.
Explanation:
Selective serotonin reuptake inhibitors are common antidepressants prescribed for patients with depression and anxiety disorders. However, these medications do not have an immediate effect. They usually have full effect within weeks, depending on the patient.
This delay, can be explained by the mechanism of action of these drugs. Selective serotonin reuptake inhibitors act by blocking the serotonin transporter which transports serotonin into the brain cells.This results in more being available outside the cells where it has it effects.
SSRIs don't work instantaneously because they do not target the transporter directly. They rather, bind to the DNAs that produce the transporter and therefore makes them less active and this leads to lower amount of transporters available. This process takes time.
