Select the claims that an ecologist might reasonably make. 1. Small animals like birds and amphibians lay eggs, but larger animals give birth.

2. Animals only take care of their young if they have fewer than 5 babies.

3. Birds decide when to start their courtship rituals and what they will do to attract a mate.

4. All flowers need bees for pollination.

5. None of the above are reasonable claims.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.

would be most reasonable answer tbh

not too sure but maybe in the hot springs.
