Which is a function of cyclins? Cyclins are carbohydrates that regulate DNA replication during the mitosis phase of the cell cycle. Cyclins are glycoproteins that repair DNA in the beginning of cell cycle. Cyclins are proteins that regulate when and how often a cell divides.

Answers

The correct answer for the question that is being presented above is this one: "Cyclins are proteins that regulate when and how often a cell divides." The function of the cyclins is that it helps regulates during cell division. They are proteins, basically.

How many protons, neutrons, and electrons does uranium-235 have

Answers

Uranium-235 is composed of 92 protons, 143 neutrons, and 92 electrons.

What are electrons?

An electron is a negatively charged subatomic particle.

Uranium-235 is a naturally occurring isotope of uranium, an element characterized by having 92 protons in its nucleus.

As all uranium nuclei have 92 protons, the nucleus of a uranium-235 atom will also have 143 neutrons to give it a total atomic mass number of 235.

Thus, Uranium-235 is composed of 92 protons, 143 neutrons, and 92 electrons.

Answer:

Uranium is element 92, so unionized, it has 92 protons and electrons. U-235 is an isotope with a total of 235 nucleons, so subtract 92 to get 143 neutrons.
