Umm where is the questions ?
ADH and aldosterone secretion are part of the body's compensation for A serious hemorrhage. Vasopressin or ADH is a hormone synthesized as a peptide prohormone in neurons in the hypothalamus and is converted to AVP. The primary role is maintaining osmolarity and thus maintaining the volume of water in the extracellular fluid, and the secondary function of ADH is raising blood pressure by constricting blood vessels. Aldosterone on the other hand is essential for sodium conservation in the kidney.
Answer:
A frameshift changes every codon past it. A base substitution only changes one codon.
Explanation:
DNA is comprised of nucleotides (A, C, T, G) that make up amino acids. Every three bases is called a codon and represents an amino acid.
In a frameshift mutation, a nucleotide is either added or deleted from the sequence. This offsets the entire sequence after it because the reading frame shifts. Here's an example:
ACTGCTATCGTCATC
If another T is added in between the first and second codons, then every codon after will be changed.
ACT>T<GCTATCGTCATC
A substitution mutation is usually less severe, as it only alters one codon in the sequence. These occur when one nucleotide is replaced by another one. Here's an example:
ACTGCTATCGTCATC
Let's say the first G is replaced by a T.
ACT>T<CTATCGTCATC
As you can see, none of the other codons changed.
Typically, a frameshift mutation is considered worse than a substitution mutation.
Answer:
The result of Telophase 1 and Cytokinesis is two haploid daughter cells that are genetically different from the original cell.
Explanation:
Telophase I. At each pole, during this stage, there is a complete haploid set of chromosomes (but each chromosome still has two sister chromatids). A cleavage furrow appears, and by the end of this stage the parent cell has divided into two daughter cells. This separation of the cytoplasm is called cytokinesis.
