Answer: B
Explanation:
Mutations are changes in the DNA sequence that can lead to genetic diversity. Mutations are usually errors in DNA replication or mitosis.
The period of time that begins with the contraction of the atria and ends with ventricular relaxation is known as the Cardiac cycle.
<h3>What is a cardiac cycle?</h3>
The cardiac cycle describes a whole heartbeat from its onset to the beginning of the following pulse. It consists of the diastole, systole, and the interval in between. Heart rate, which is naturally expressed as beats per minute, serves as an example of how a cardiac cycle occurs.
<h3>Cardiac Cycle Physiology</h3>
The left and right halves of the human heart's four chambers make up the body. The right and left ventricles are located in the lower two chambers, while the left and right atria are located in the two top chambers. Pumping deoxygenated blood to the lungs through the pulmonary arteries and the pulmonary trunk is the right ventricle's main job. While the left ventricle is in charge of pushing freshly oxygenated blood to the body through the aorta.

Answer:
Energy that is not used in an ecosystem is eventually lost as heat. Energy and nutrients are passed around through the food chain, when one organism eats another organism. ... In each case, energy is passed on from one trophic level to the next trophic level and each time some energy is lost as heat into the environment.
Answer:
Chemosynthesis occurs around hydrothermal vents and methane seeps in the deep sea where sunlight is absent. ... In the diagram mussels and tubeworms are using the hydrogen sulfide released from a hydrothermal vent. The chemical equation given here for chemosynthesis is just one of a number of possibilities.
