La Fase más larga del Ciclo Celular es_____________________ y en ella ocurre____________________________________________________ _______________________________________________________________________________________________________________________________

Answers

Answer:

La fase más larga del ciclo celular es la interfase  y en ella ocurre una gran producción de proteínas.

Explanation:

La célula pasa el 90% del tiempo del ciclo celular en la interfase, lo que significa que esta es la fase más larga del ciclo celular.

La interfase ocurre entre dos divisiones celulares consecutivas y es el período en el que la célula no se divide, sino que se prepara para ello, produciendo tantas proteínas como sea posible, que serán utilizadas en la división. Esta fase es tan grande que se divide en tres etapas llamadas G1, S y G2.

T / F Nitrogen is present in carbohydrates but not proteins.

Answers

False. Carbohydrates only contain the elements carbon, hydrogen, and oxygen. The building blocks of proteins, amino acids, contain—at the very least—carbon, hydrogen, oxygen, and nitrogen. Thus, nitrogen is not present in carbohydrates, but it is present in proteins, making the given statement false.

Nitrogen is present in proteins. So, the given statement is False.

What are Biomolecules?

A biomolecule is defined as a chemical compound found in living organisms that mainly includes chemicals composed of carbon, hydrogen, oxygen, nitrogen, sulfur and phosphorus. Biomolecules are the building blocks of life and perform important functions in living organisms.

ATP provides energy needed to carry out many cellular functions. Which of the following processes does NOT require ATP? A. active transport of a protein across a membrane B. making more ATP C. passive transport of oxygen across a cell membrane D. muscle contractions

Answers

C. Passive Transport

ATP provides energy needed to carry out many cellular functions. Passive transport of oxygen across a cell membrane is does not require ATP. Hence option C is correct.

What is cellular function?

Cellular function is defined as protein synthesis, translocation of molecules across the cell membrane, and cell division to create new cells. They provide the body with structure, take in food's nutrients, convert them into energy, and carry out certain functions.  Additionally, cells have the ability to replicate themselves and contain the body's genetic material.

In primary active transport, molecules are moved across a membrane against their gradient directly using a chemical energy source (such as ATP). Ion transport, muscular contraction, nerve impulse transmission, substrate phosphorylation, and chemical synthesis are just a few of the processes that use ATP as an energy source. By adding a phosphate group to another molecule, ATP can drive biological operations.

Thus, ATP provides energy needed to carry out many cellular functions. Passive transport of oxygen across a cell membrane is does not require ATP. Hence option C is correct.

what is the charge of an ion with 16 protons and 14 electrons? helppppppp​

Answers

Answer:

Thus, each atom or ion of sulfur must contain 16 protons. We are told that the ion also has 16 neutrons, meaning the mass number of the ion is 16 + 16 = 32. Because the ion has 16 protons and 14 electrons, its net charge is 2–. Thus, the symbol for the ion is 32S2–.

Explanation:

The charge of an ion with 16 protons and 14 electrons is positive.

What is an ion?

An ion is a gross electrically charged atom or a molecule. By convention, the charge of an electron is considered to be negative, and this charge is equal to and opposite to the charge of a proton, which is considered to be positive.

Ions are formed by adding or removing electrons from neutral atoms, molecules, or other ions; or by combining ions with other particles.

When atoms gain or lose electrons, ions form. Because electrons are negatively charged, losing one or more electrons causes an atom to become positively charged.

Gaining one or more electrons causes an atom to become negatively charged. The attraction between positively and negatively charged ions is known as ionic bonding.

Thus, the ion here is positive as it have more protons than electron.
