The systemic circulation is as follows:
The blood flows from the left atrium to the left ventricle. From there, it goes into the aorta where it gets distributed to the rest of the body. The blood would then go into the vena cavae and then to the right atrium, then to the right ventricle. It would go to the pulmunary arteries then get distributed to the lungs. Then the pulmonary veins would carry the oxygenized blood back to the left atrium and the cycle continues.
Your answer would be D) because at each increasing level of the energy pyramid, there is 10% lost as heat
Point mutations can show three different types of effects:
- Base substitutions can be silent mutations in which the changed codons correspond to the same amino acid.
- Base substitutions can be missense mutations where the changed codon corresponds to a different amino acid.
- Base substitutions can be nonsense mutations in which the altered codon corresponds to the stop signal.
<h3>What are point mutations?</h3>
Point mutations are changes to the N base of DNA or RNA. Point mutations are common, but their effects can be mitigated by gene recovery mechanisms.
The cause of this point mutation is due to 4 factors:
- Errors during DNA replication by mutagens.
- Breaking of oxygen-phosphate bonds.
- Substitution of base pairs.
- Changes in the number of bases.

Twin Studies-genetic-the answer is true, according to quizlet -> The rationale for twin studies is that both identical and fraternal twins normally develop under similar environmental conditions. However, identical twins share more genetic kinship than fraternal twins. So if pairs of identical twins are more similar in intelligence than fraternal twins, it's presumably because of their greater genetic similarity.
And these studies do show that on average, identical twins are more similar than fraternal twins.
