<span>These are the three most common types of stresses that occur at different types of plate boundaries.
Compression- convergent boundaries
Tension- divergent boundaries
Shear- transform boundaries
Therefore, Compression, or compressing stress, is the major type of stress that occurs at convergent plate boundaries.</span>
Answer:
<u><em>These mutations form new alleles that increase genetic variation in a population. This variation may lead to new species which increases biodiversity.</em></u>
Explanation:
Mutations are randomly occurring modifications that exist within the genetic code, leading to replication errors in DNA. DNA molecules are long-chain, helical macromolecules that store genetic material. They consist of different monomer sequences called nucleotides. In a reading frame, which contains instructions for protein production, they shape base pairs and codon sequences.
Single nucleotide polymorphisms are normal, as silent mutations, which sometimes result in no changes in amino acids. Some mistakes add a random nucleotide (SNP) in point mutations resulting in new alleles.
Frameshift mutations occur from nucleotide insertions or deletions that are not divisible by 3. This results in the codon requiring more or fewer nucleotides which disrupt the reading frame, resulting in a separate protein translation.
Answer:
True
Explanation:
Epinephrine and norepinephrine are the hormones secreted by the adrenal medulla and are also called adrenaline and noradrenaline, respectively. During stress conditions, the hypothalamus stimulates the preganglionic neurons of sympathetic division.
These preganglionic neurons stimulate the chromaffin cells to secrete epinephrine and norepinephrine to prepare the body for fight or flight response. The increased level of epinephrine and norepinephrine hormones in the blood is called “surge of adrenaline”
