Answer:

The options

A. It suggested that DNA is the

"transforming principle."

B. It confirmed that DNA is a double helix composed of two antiparallel strands.

C. It demonstrated that DNA consists of four nucleotides where the proportions of adenine/thymine and cytosine/guanine remain constant.

D. It proved that DNA is

semiconservative replication.

The CORRECT ANSWER IS A.

A. It suggested that DNA is the

"transforming principle."

Explanation:

A. It suggested that DNA is the

"transforming principle."✔

Griffith's experiments proved

that transformation can be seen in

pneumococcus, but gave no proof based on what molecular background the transformation was

WHILE, the Avery MacLeod-McCarty experiments proved that DNA was THE TRANSFORMING PRINCIPLE.

B. It confirmed that DNA is a double helix composed of two antiparallel strands.❌

These findings were established by James Watson, Francis Crick, Maurice Wilkins and Rosalind Franklin

C. It demonstrated that DNA consists of four nucleotides where the proportions of adenine/thymine and cytosine/guanine remain constant.❌

The findings was established by Erwin Chargaff.

D. It proved that DNA is semiconservative replication.❌

The findings was established by Matt Meselson and Franklin Stahl.

Under what conditions will the body use significant amounts of protein for energy during exercise?a.Inadequate calorie intakeb.I
irga5000 [103]

Answer:

Hello!

The answer is b. inadequate calorie intake and inadequate carbohydrate storage

Explanation:

Our body requires energy to carry out daily activities and body functions. This energy is available to the body in three forms:

  1. carbohydrates
  2. fats
  3. proteins

Carbohydrates are the first and most readily available source of energy as starch and complex carbohydrates and sugars are immediately broken down into glucose which is available for body cells. Excess glucose is also stored as glycogen in the muscles. During exercise, carbohydrates, particularly, glucose are the first sources of energy for the body.

Fats provide the highest energy of all three (9 kilocalories compared to 4 of protein and carbohydrates). Fats are stored in the body in the form of adipose tissues or body fat. Any excess energy is readily stored by the body in the form of fats.

As proteins are not stored by the body, they are the last to be broken down during strenuous or prolonged exercise. Protein, particularly the skeletal muscle is the last to be used for energy in case of low calorie intake and inadequate carbohydrate stores.

Ocean current direction is influenced by
Brrunno [24]

Answer: C. Prevailing winds

Explanation:

Several factors influence the direction of the sea current, and the prevailing wind is one of them. Surface winds are certainly one of the most critical factors affecting the direction of movement. In addition to this factor, the evolution of the sea current is also influenced by the earth's rotation, temperature, the attractive force of the moon and river flows.

What is the correct answer for number 14 ? Explain why please !!
pshichka [43]

2) The concentration of O2 will increase inside the cell.


The cell will want to reach equilibrium, meaning that there should be an equal number of oxygen inside and outside the cell.  In the picture, more oxygen is shown outside the cell than inside so oxygen will flow into the cell until it has reached equilibrium.  Therefore, the concentration of O2 will increase in the cell.


Hope this helps!!
