Which of the fallowing describes the difference between nitrogen-14 and nitrogen-15

Nitrogen-14 has a mass number of 14 which means that it has a total of 14 protons and neutrons. When you subtract the atomic number of nitrogen from the mass number of 14 you get the number of neutrons (14-7), which gives you 7 neutrons. Now for nitrogen-15, you have a different mass number which means there is a different amount of neutrons (15-7), 8 neutrons. So the difference is the mass numbers and the number of neutrons (the number of protons remains the same however). When there are two versions of the same element, and they have the same number of protons, but different number of neutrons and different mass numbers, they are called isotopes. Hope this helped :)

What type of enzyme can activate another enzyme by adding a phosphate from ATP?

Rzqust [24]

Answer:

Here my answer goes.......

Explanation:

In biochemistry, a kinase is an enzyme that catalyzes the transfer of phosphate groups from high-energy, phosphate-donating molecules to specific substrates. This process is known as phosphorylation, where the substrate gains a phosphate group and the high-energy ATP molecule donates a phosphate group.

Positive selection tests to see if the ______ of a T-lymphocyte can recognize and bind to an MHC molecule.

DENIUS [597]

Positive selection tests to see if the TCR of a T-lymphocyte can recognize and bind to an MHC molecule.

<h3>What is a T-lymphocyte?</h3>

A T-lymphocyte is a special type of immune cell that is generated inside the bone marrow.

The T-cell receptor (abbreviated as TCR) is a protein located on these immune T lymphocytes.

In conclusion, Positive selection identifies if the TCR of a T-lymphocyte can recognize and bind to an MHC molecule.
