Population growth comes from a balance between food supply and predators. When pray increases food supply decreases, since they are eating them alot. As a result some of the prey dies off since there isn't enough food for them. Then the food supply increases but then suddenly dies off after pray comes backs and eats them. As a result the cycle continues

Answer:
Tropomysin, calcium
Explanation:
Tropomysin is a protein that prevents muscle contraction hence acts as a contraction inhibitor. It wraps around the actin blocking the binding sites for myosin on the actin.
Muscle will only contract when they get a rush of calcium ions.
The calcium ions binds to troponin, the troponin changes its shape. The change in shape will remove tropomyosin from the binding sites allowing myosin to bind on the actin leading to muscle contraction.
Answer:
Carbohydrates - monosaccharides
Proteins - amino acids
Nucleic acids - nucleotides
Lipids - fatty acids (hydrocarbon chains)
Explanation:
There are four major biological molecules called biomolecules in nature namely; carbohydrates, proteins, nucleic acids and lipids. These four molecules form the bedrock upon which life is built. The biomolecules mentioned above are POLYMERS formed as a result of the combination of two or more simpler molecules called MONOMERS in a process called CONDENSATION.
The monomer of each polymeric biomolecule is as follows;
Carbohydrates - monosaccharides
Proteins - amino acids
Nucleic acids - nucleotides
Lipids - fatty acids (hydrocarbon chains)
Definition:
Having two different alleles of a particular gene or genes.
(an Allele is a variant form of a gene.)
Simplification:
If the organism has one copy of two different alleles, it is heterozygous.
Eg: T and t
<em> </em><em> </em><em> </em><em> </em><em> </em><em>(</em><em>T</em><em> </em><em>for </em><em>tall</em><em> </em><em>and</em><em> </em><em>t</em><em> </em><em>for</em><em> </em><em>short</em><em>)</em>
Example:
<u><em>Pea</em><em> </em><em>Plants</em></u>
Pea plants can have red flowers and either be homozygous dominant (red-red), or heterozygous (red-white). If they have white flowers, then they are homozygous recessive (white-white). Carriers are always heterozygous.
