This refers to any variable or factor in the environment which limits the population expansion of a given species.

In the case of Orca they are present in the sea and need food and dissolved oxygen to survive which is why it acts as a limiting factor due to their absence causing a decline in population.

suppose a cell wishes to make a protein that has 100 amino acid. How many water molecules will be created in the making of this
slega [8]
The answer is 99.

Amino acids <span>contain a carboxyl group (carbon-containing) and an amino group (nitrogen containing). Proteins are made by forming peptide bonds between the carboxyl and amino group of amino acids.
</span>If a protein is made of 100 amino acids, that means there are 99 peptide bonds (because the last, 100th amino acid will not bind the next (101st) amino acid). For each peptide bond that is created, one oxygen atom and two hydrogen atoms are taken. Therefore, one water molecule is created for each peptide bond. If there are 99 peptide bonds, 99 water molecules are created.

What evidence is there that the universe is expanding? Explain.
Vsevolod [243]

This is evidenced by Doppler shift effect. This is the phenomenon where waves that are coming from an object that is accelerating towards your direction are heard at a higher frequency than that of objects moving away from you. This is the same for light (which also has wave-like properties). When observing distant galaxies, astronomers discovered that they all showed to be redshift (change in the frequency of light towards red color). This means that all galaxies are moving away from each other because the universe is expanding.
