It is a half and half chance, we just were learning about this! The one parent has wet and the other dry it would be half and half.
Because the soil didn't have the same nutrients it has now due to lack of decomposition of other plants and animals.
Answer:
Motor nerves
Explanation:
Pulling the leg quickly from the sharp object is an example of reflex action. It includes sensory receptors, sensory neurons, interneurons, the control center (spinal cord), motor neurons and effector.
As soon as she steps on the glass piece, the receptors present in the skin of her foot sole sense it and send the information to the control center via sensory neurons. The spinal cord commands the muscles of the effector organ (leg) via motor neurons to move to step away from the glass piece.
Matter that is not used by consumers in the food chain become "detritus". Detritus, meaning debris or waste, are materials that are missed or uneaten by consumers. Because they do not participate in higher trophic levels, these materials are left to decompose. Detritus is often considered the "missing mass" when measuring the total mass in the food chain.
Answer:
lungs:
The blood first enters the right atrium.
The blood then flows through the tricuspid valve into the right ventricle.
When the heart beats, the ventricle pushes blood through the pulmonic valve into the pulmonary artery.
The pulmonary artery carries blood to the lungs where it “picks up” oxygen.
It then leaves the lungs to return to the heart through the pulmonary vein.
The blood enters the left atrium.
It drops through the mitral valve into the left ventricle.
The left ventricle then pumps blood through the aortic valve and into the aorta. The aorta is the artery that feeds the rest of the body through a system of blood vessels.
Blood returns to the heart from the body via two large blood vessels called the superior vena cava and the inferior vena cava. This blood carries little oxygen, as it is returning from the body where oxygen was used.
The vena cavas pump blood into the right atrium and the cycle begins all over again.
