<h2>The correct option is (B).</h2>
Explanation:
- Cerebrum is the largest and anterior part of the brain.
- It consist of two hemisphere, left and right hemispheres and is situated in the front area of the skull.
- Cerebrum is divided into four sections which is called as lobes.
- These lobes of cerebrum are as folows:
- Frontal lobe
- Temporal lobe
- Parietal lobe
- Occipital lobe
- It plays an important role in the sensory and neural functions.
- It is also responsible for the coordination of voluntary activity in the body.
The stress hormones epinephrine and norepinephrine are used by your body to respond to short-term stressors while the stress hormone cortisol provides a more sustained release of energy for prolonged stress.
Epinephrine and norepinephrine are produced by the adrenal medulla during the flight/fight stress response and increase blood pressure, heart rate, and glucose.
<span>The cortisol is steroid hormon with several funstions, one of them is to help the body manage stress</span>
Option A, a fault is always younger than the rock it cuts through
Reason:
Basically there are three modes of determining the age of rock
1) In a sedimentary rock, the layer at the bottom is the oldest. It is called as law of super position
2) If a rock layers lies below an extrusion, then it is always older than the extrusion
3)a fault is always younger than the rock it cuts through
Answer:
The experiment conducted in 1952 by hershey and chase consisted in the use of sulfur to track proteins and radioactive phosphorus to track DNA from T2 phages that infect bacterial cells, the key result was that phage proteins were outside the cell during the infection but the DNA was inside the cells because new phages were obtained with radioactive phosphorus. This allows us to conclude that DNA acts as a genetic material of phage T2
Answer is A. The positively charged R group of a basic a.a could bind to DNA.
Basic amino acids have a positive charge and acidic amino acids have a negative charge. DNA also has negative charge because of the phosphate group in nucleotides. So they have opposite charges and can form ionic bonds.
Hope this helps:)
