The actual answer is size and temperature

All stars are very hot. They resemble a gigantic furnace of atomic energy. Some stars are much hotter than others and appear to be brighter. The brightness of a star also depends upon its size and its distance from the Earth. Larger stars tend to be brighter, but a star closer to the Earth will appear brighter than one the same size that is farther away.

Brums [2.3K]

In prolonged fasting conditions acetyl-coa generated from the breakdown of amino acids and fatty acids does not enter the citric acid cycle in the liver, but acetyl-coa derived from ketone bodies can enter the citric acid cycle in the brain. <u>Cholesterol is required in the diet.</u>

<h3>What is amino acids?</h3>

Amino acids are chemical molecules having side chains (R groups) unique to each amino acid as well as amino and carboxylic acid (CO2H) functional groups.

Every amino acid contains the elements carbon (C), hydrogen (H), oxygen (O), and nitrogen (N) (CHON); in addition, the side chains of cysteine and methionine contain sulfur (S), while the less frequent amino acid selenocysteine has selenium (Se). As of 2020, it is known that more than 500 naturally occurring amino acids make up the monomer units of peptides, including proteins.

Despite the fact that there are only 22 proteins, 20 of them have unique specified codons, and another two have unique coding mechanisms: All eukaryotes contain selenocysteine, and pyrrolysine is also present.

Which statement describes how chemical formula such as H20 represent compounds check all that apply
Allisa [31]
<h3>Answer:</h3>
  • They show the elements of make up a compound
  • They show the types of atoms that make up a molecule
  • They show the number of each type of atom in a molecule
<h3>Explanation:</h3>

To answer this question we need to know what is a compound.

  • A compound is a substance that is made by two or more atoms of different elements that are chemically combined.
  • A chemical formula of a compound is a formula that shows the elements that make up a compound and also the types of atoms that make up the molecule.
  • Additionally, the chemical formula shows the number of each type of atom in a molecule.
  • In this case, the chemical formula of a molecule of H₂O shows that it is made up of one hydrogen atom and two oxygen atoms.

Difference between protons neutrons and electrons?
photoshop1234 [79]
Protons and neutrons are in the nucleus of an atom, whereas electrons are present in orbitals, or shells, outside an atom. Electrons are negatively charged, protons positive, and neutrons have no charge, or are neutral. Protons and neutrons have a relative mass of approx. 1 Atomic Mass Unit (amu), whereas electrons have a relative mass of approx 0.00055 amu.
