20. Neutrons and are found in the nucleus of an atom. (1 point)

1 answer:

4 0

You know that neutrons are found in the nucleus of an atom. Under normal conditions, protons and neutrons stick together in the nucleus. During radioactive decay, they may be knocked out of there. Neutron numbers are able to change the mass of atoms, because they weigh about as much as a proton and electron together.

Bingel [31]

<h2>The answer is False</h2>

Explanation:

Fluorine is a Chemical element. Its symbol is F. Its atomic number is 9. Fluorine is a lightest in nature. It is a diatomic pale yellow gas.

Except helium, neon and argon, fluorine is highly reactive to react with other elements.

The reason for it is false, because the outermost energy level of fluorine is not filled.

Fluorine becomes stable, when it forms an ionic bond with another atom.

What are the stages of meiosis in eukaryotic cells with realizing that there are two cell divisions involved?

goldenfox [79]

Answer:

Meiosis can only occur in eukaryotic organisms. It is preceded by interphase, specifically the G phase of interphase. Both Meiosis I and II have the same number and arrangement of phases: prophase, metaphase, anaphase, and telophase. Both produce two daughter cells from each parent cell.

These are nucleotides that have a single ring structure. Example: Cytosine, Thymine, and Uracil

IgorLugansk [536]

Answer:

The question is incomplete.

However, I notice that your question is mainly dealing with

"Nucleotides with a single ring structure"

I tackled that part, also providing explanation to the point you focused on.

Explanation:

Nucleotides are compounds in which nitrogenous bases (purines and pyrimidines) are conjugated to the pentose sugars (ribose or deoxyribose) and at least one phosphate group. Thus a nucleotide consists of a nitrogenous base, pentose sugar and at least one phosphate group.

Examples of the nitrogenous bases are Adenine, Guanine, Thymine, Uracil and Cytosine. Of all, Thymine, Uracil and Cytosine are with single ring, while Adenine and Guanine are double ring structure.

Sonbull [250]

Answer:

Pancreatic juice, NaHCO₃.

Explanation:

The buffers are the chemical solution which neutralizes the acidic effect and the human body also produces the biological buffers which help maintain the pH.

The pancreatic juice secreted by the pancreas gets drained into the duodenum of the small intestine and neutralizes the effect of the acidic content in the stomach bolus. The pancreatic juice contains the sodium bicarbonate which neutralises the effect of the HCl.

Thus, Pancreatic juice, NaHCO₃ is the correct answer.
