In an experiment you, the researcher, remove atp from the system. what would be a likely consequence of the lack of atp on muscle contraction?

Answers

The tropomyosin filament would not be dislodged preventing contraction.

The cross bridges would remain linked and therefore contraction would stop

The cross bridges would break apart due to the presence of calcium ions enabling some contraction

The myosin heads would separate from the actin molecule due to the release of ADP that was previously present.

Explain how hypertension, heart disease, and stroke are related.

Answers

Hypertension, heart disease, and stoke are related because they all have to do with the heart. Hypertension is when you have high blood levels, heart disease is when your heart doesn't work properly, and stoke is when the heart beats hyperactively or the opposite.
Hypertension is another term for high blood pressure. This occurs when there is too much pressure put on the blood vessels. The heart gets affected because it is pumping against the pressure, which causes strain on the heart. This can cause thickening of the heart walls, which can lead to other heart problems.

Stroke occurs when there blood supply to the brain is reduced or obstructed. This deprives the brain of oxygen and other nutrients. The occurrence of stroke increases with blood pressure because there is persistent pressure on the vessels which can ultimately lead to stroke. 

Sponges move huge volumes of water through their bodies every day. Although this serves the function of filter feeding for the organism, how might this also provide an “ecosystem” service (something that affects and/or benefits other organisms in their environment)? "which one below is the right answer and why?" a/ They can filter small poisonous fish out of the water that may harm other organisms. b/ Their body chambers serve as places where smaller organisms can live and be protected from certain predators. c/ They produce large numbers of gametes that will become food for other sponges. d/ They create small currents in their microenvironment that help to circulate and clean water locally for other organisms.

Contractile vacuoles are organelles that are responsible for excretion function. They perform osmoregulation which manages wastes, water and other needed materials in the cell. They are found in some prokaryoric organisms like the algae, protists, amoeba and other unicellular organisms.
