I think that a basic experiment involves a minimum of two participants group(s). Simple or basic experiment are ones that researchers use to determine if changes in one variable might lead to changes in another variable. In these experiments looking at the effectiveness of a new medication, for example, study participants may be random.

C cells of the thyroid gland secrete __________. C cells of the thyroid gland secrete __________. tetraiodothyronine cortisol ca
Leni [432]

C cells of the thyroid gland secrete calcitonin.

<h3>What does C cells of thyroid gland produce?</h3>
  • The thyroid follicle, which is the gland's active component, is encircled by a single layer of epithelial cells, and the lumen is stuffed with colloidal material.
  • It includes parafollicular cells, or C cells, which release calcitonin.
  • The C-cells of the thyroid gland secrete calcitonin, a 32 amino acid hormone.
  • When the concentration of blood calcium has grown over the usual range, the thyroid gland releases the hormone calcitonin, which lowers the level.
  • The parafollicular cells, sometimes referred to as the C cells, of the thyroid gland are the principal producers of this polypeptide hormone, which has 32 amino acids.

Explain why evolution is a unifying theme
Setler [38]
Unify means to make or become united uniform, or whole.

(I personally don't agree that evolution is true; but here is my answer)

Evolution is a way Scientists like to theorize the world was made/ created. They try to explain why everything can about in a uniform way. Everything has a reason or theory. Even though scientists haven't been able to prove that Evolution actually exists, many people like the idea of it- just for the reason that it gives a more believable whole approach to how the Earth and Universe came about. For some people, it is more uniform than a religion.

I hope this helped you!

For a science fair project, two students decided to repeat the Hershey and Chase experiment, with modifications. They decided to
posledela

Answer:

The correct answer will be option-E

Explanation:

Hershey and Chase's experiment was performed to test whether DNA serves as the genetic material or protein.

To perform experiment they grew bacteriophage into radiolabeled phosphorus and sulfur compounds. The phosphorus is an integral part of the structure of DNA whereas proteins contain sulfur in their structure.  

In the given condition if radiolabeled nitrogen is utilized then the experiment will fail as the structure of proteins also contains an amino group( NH₂) in their structure as well as DNA. The scientist will not be able to identify whether the DNA is the genetic material or protein.

Thus, option-E is the correct answer.

7. Explain why we have 4 seasons.
Juliette [100K]

Answer:

The four seasons happen because of the tilt of the Earth's axis. At different times of the year, the sun's rays hit different parts of the globe more directly. The angle of the Earth's axis tilts the Northern Hemisphere towards the sun during the summer.

How does the cell regulate the substrate specificity of ribonucleotide reductase to maintain equal amounts of all four deoxynucl
Kruka [31]

Answer:

The correct answer is A When dTTP is bound to the specificity site, more dCDP is produced

Explanation:

Ribonucleotide reductase catalyzes the conversion of ribonucleotide to deoxyribonucleotide.

                  When dTTP is bound to the specificity site at that time dCDP is produced.The So formed dCDP is converted to dUDP by the help of dCDP deaminase.The dUDP is then converted to dUTP by phosphorylation.

               Finally the dUTP is converted to dTTP by the catalytic activity of thymidylate synthase with the presence of N5 N10 methylene tetrahydrofolate.

        Thus equal amount of deoxyribonucleoside triphosphates  are maitained by the cell.
