Answer:
more helium
Explanation:
the sun is mostly made up of helium and as it grows it becomes denser and the core holds more helium
Heterotrophic organisms require nitrogen and carbon for nutrition.The reason is primarliy based on the theory primordial soup. It also have a lot to do with organic compounds.
1) Amino acids. Option B.
2) Phosphorus. Option D.
<h3>What are proteins?</h3>
Proteins are macromolecules made up of 2 or more amino acid units linked together by peptide bonds.
According to the passage, antibiotics work by breaking down the cell water proteins of bacteria. When proteins are broken down, they are broken into their component amino acids.
Therefore, when the researchers examine the phagocyte, the presence of amino acids would be an indication of the effectiveness of the antibiotics.
Amino acids are made up of elements such as nitrogen, carbon, oxygen, and hydrogen. Thus, if the researchers examine the monomers present in the phagocytes, all these elements should be found. Except for phosphorus.

Answer and Explanation:
Density-dependent factors include competition, predation, parasitism and disease. When organisms are densely populated, they can easily transmit parasites and diseases to one another through contact with skin and body fluids. Disease is spread quickly through densely packed populations due to how close organisms are to one another. All these factors can affect the volume of a population. Predation affects population because the predators feeds on the prey by killing it.
