Diagram D represents 2 chromosomes, each with 1 chromatid which contain a centromere at the medium level.
<h3>What is cell division?</h3>
Cell division is the process by which cell divides, which requires the prior duplication of the genetic material during the synthesis (S) phase.
Subsequently, the genetic material is condensed in prophase to form a chromosome having two sister chromatids linked at the centromere level, which separate during anaphase.
The phases of cell division or mitotic cycle in which sister chromatids and chromosomes are separated into daughter cells include prophase, metaphase, anaphase and telophase.
In conclusion, Diagram D represents 2 chromosomes, each with 1 chromatid which contain a centromere at the medium level.

Answer:
<u><em>Ecosystem </em></u>
Explanation:
The answer would<em><u> Ecosystem</u></em> because Ecosystems consist of a geographic area where living animals, plants, animals, weather and landscape that work together to form a bubble of life.
You have the two wolves & five moose as animals, trees as landscape/plants, granite rock as landscape, shallow pond as landscape.
The wolves, moose, trees, rock, and shallow pond work together to create an ecosystem.
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".
The sugar molecules thus formed contain carbon, hydrogen, and oxygen: Their hydrocarbon backbones are used to make amino acids and other carbon-based molecules that can be assembled into larger molecules (such as proteins or DNA), used for example to form new cells.
