Answer: Exercise causes the heart to pump blood into the circulation more efficiently as a result of more forceful and efficient myocardial contractions, increased perfusion of tissues and organs with blood, and increased oxygen delivery. Aerobic exercise trains the heart to become more efficient.

Answer:
Option D, spatial reproductive isolation—the only reason these two species don’t mate is because of the inability of the middle land to be occupied
Explanation:
It is clear from the question that the two bird populations with different color are able to mate and reproduce viable and fertile offspring when brought together. Hence, the only problem due to which these two bird population were not breeding with each other was their distant location and habitat.
Location and habitat are characteristic of spatial distribution and hence they were separate because of spatial reproductive isolation
Hence, option D is correct
Answer:
The Bicuspid valve or Mitral valve found between the left atrium and left ventricle.
Explanation:
- A bicuspid valve or Mitral valve is an atrioventricular valve. It is one of the valves of the heart's four valves.
- It regulates the blood flow from the left atrium (upper left chamber) to the left ventricle (lower left chamber).
- It mainly prevents the backflow of blood from the left ventricle to the left atrium.
Electrolytes are nutrients in your body that have important, regulatory functions. An athlete can maintain electrolyte balance by in-taking sodium and potassium.

Answer:
QPGREDRPLP
Explanation:
A codon consists of a set of three mRNA nucleotides which corresponds to an amino acid. There are 64 codons which code for 20 amino acids (AA). A DNA sequence is first transcribed to mRNA which is then translated to form protein. According to the given sequence, the first 10 amino acids for this particular sequence will be:
GTC = CAG mRNA = Glutamine AA (Q)
GGT = CCA mRNA = Proline AA (P)
CCA = GGU mRNA = Glycine AA (G)
GCA = CGU mRNA = Arginine AA (R)
CTT = GAA mRNA = Glutamic acid AA (E)
CTG = GAC mRNA = Aspartic acid AA (D)
TCT = AGA mRNA = Arginine AA (R)
GGC = CCG mRNA = Proline AA (P)
GAT = CUA mRNA = Leucine AA (L)
GGC = CCG mRNA = Proline AA (P)
Hence, in single letter codes these amino acids will be represented as :
