Answer:
B. atrioventricular (AV) valve
Explanation:
The function of the conduction system of the heart is to spread the electric signal and make the heart contract in coordinated timing. Conduction starts at SA node, then the AV node then will spread by bundle branches.
The atrioventricular valve is not part of the conduction system. The valve function is to keep the blood flow back. If the valve is broken and blood did flow back, it can make the heart need to do more work than usual.
Different monomers contain different kinds of atoms needed to produce different end products
Answer:
The amount of light they receive.
Explanation:
In an experiment, the independent variable is the part of the experiment that the experimenter changes. In this experiment, the only thing that's different for each of the plants is the amount of light they receive. Everything else is the same - the same amount of soil, same amount of water, same pots, and so on.
Answer: CONDITIONS FOR HARDY
No mutations should appear in the beetle population because new alleles would change the allele frequencies
There should be random mating among beetles
There should be no natural selection on the beetle population
The population of beetles must be large enough so that genetic drift is avoided
There should be no migration of beetles into or out of the population.
CONDITIONS FOR EVOLUTION-
Natural selection favors green beetles
Purple mutants appear among the Beatles
Preferred mates are red, so these individuals reproduce
Large numbers of brown beetles were killed in a forest fire
A significant number of yellow beetles left.
Explanation: I only added about half the sentence of each answer because it’s to long.
