Answer:
The correct answer would be Atria push blood into the ventricles and Ventricles push blood out of the heart.
In humans, four chambered heart is present with two atria and two ventricles.
Deoxygenated blood from all over the body is passed into the right atrium through vena cava (superior and inferior).
Simultaneously, oxygenated blood from the lungs is passed into the left atrium of the heart with the help of pulmonary vein.
Both the atria contract at the same time to drain their blood into respective ventricles.
The ventricles undergo relaxation while receiving blood.
The valves present between the atria and ventricles (tricuspid and bicuspid valve) ensures that the blood flows in one way direction only. They shut down as the ventricles contract and produce the sound "lub".
The ventricles contract simultaneously to pump blood out of the heart. The right ventricle pumps deoxygenated blood into pulmonary artery which takes the blood to the lungs for oxygenation.
The left ventricle passes the oxygenated blood through aorta to all the parts of the body.
The pulmonary and aortic valves prevent the back flow of blood and shut at the same time which creates second sound called as "dub".
A long-lasting influence of historical processes on the current ecology of an area is called a legacy effect.
<h3>What is the legacy effect caused by?</h3>
- Legacy effects are alterations to the environment brought on by earlier human disturbances.
- Changes in land use and land cover, fire regime, water diversion, the introduction of chemicals or isotopes, other disruptions of natural processes,
- Or combinations of these changes may all contribute to the disturbance.
<h3>What is an Ecology?</h3>
- Ecology is the study of interactions between living things, such as humans, and their natural surroundings.
- The levels of individuals, populations, communities, ecosystems, and biospheres are all taken into account in ecology.

Answer:
Medial temporal lobe of brain
Explanation:
It is a main part of limbic system and process emotions. It is a cluster of neurons called as<em> basolateral complex</em> that are specialized for emotion processing.
Even species that are kept as pets and in aquariums should be regulated and tracked because their accidental release can have serious negative environmental impacts. Some owners and aquarium keepers intentionally release these species into the wild rather than destroy them, and accidental release is always a risk. Therefore, if a potentially destructive species is going to be kept as a pet or in an aquarium they should be regulated so proper safety precautions can be taken.
