<span>The processes of photosynthesis and cellular respiration are complimentary. During these energy conversions some energy is lost in the form of heat. Most things that create and use any type of energy find that some is often lost in the form of heat.</span>
Answer:
The correct answer is A) ingestion
Explanation:
Heterotrophs are organisms that depend on other organisms to get nutrition because they can not make their food. The process by which they take nutrition is called injection.
During ingestion, they consume the performed organic molecule. Mouth is the organ that helps in ingestion of the food. Then the food is digested in the body of the heterotrophs by the action of different enzymes.
For example, humans are heterotrophs that do ingestion of food from its mouth and then the food is digested by different hydrolytic enzymes. So the correct answer is A.
Answer:
When the heart contracts the body tissue receives its blood supply. When the heart relaxes the heart ventricles receive its blood supply.
Explanation:
The cardiac cycle consists of contraction and relaxation of the heart. The contraction is called systolic pressure and relaxation is called diastolic pressure.
The systole and diastole are mainly concerned with the ventricles, still, articular contraction and relaxation also occur. The blood from the auricles pushes into the ventricles. This is because of the auricular contraction. This initiates by SA node with a "Lub" sound.
The contraction means the pressure of the blood is more in the auricle and the mitral valve and tricuspid valves open. The blood enters the ventricles. Then the pressure of auricles becomes less.
Now the ventricles are filled with blood and the pressure of the blood is more in the ventricles. This is called ventricular systole, and it leads to open the semilunar valves.
The blood is ejected out by aorta and supply to different parts of the body. After the blood ejection, the ventricles are in the relax stage, which is called the diastolic stage.
One systolic pressure is followed by one diastolic phase. Due to systolic pressure/ contraction, the blood pumps out of the heart.
Your nerves go into your bone, I know it sounds crazy but its true, your Skeletal system is mixed with your nerves, it helps you function, without your nerves going into your bones we couldn't be able to feel if a bone is hurting or if you are getting hurt without your nerves you couldn't feel pain your nerves help you feel pain and where the pain is coming from.
