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".

Schach [20]

Answer:

The root beer exerts a force on all sides of the ice cream. These forces are all equal and cancel each other out. Gravity pushes downward on the ice cream. The ice cream floats because the buoyant force is greater than the weight of the ice cream.

-An element is a pure substance that cannot be broken down into different types of substances by chemical means. All elements are pure substances. An element is composed of a single kind of atom. An atom is the smallest particle of an element that still has all the properties of the element.

-Tungsten is an element and therefore a pure substance.

scoundrel [369]

Answer: D. 100%

Explanation:

One parent is with is a true breeding blue flowering plants this means the two alleles of the genotype are homozygous dominant alleles (BB).

The other parent is a true breeding with flowering plant, this means the two alleles of the genotype are homozygous recessive alleles (BB).

When both parents are crossed, the possible genotype outcome is

B B * b b

Bb Bb Bb Bb

Therefore since the blue flowering plant allele (B) is dominant to the white flowering plant allele (b) the probability of an offspring outcome to be a blue flowering plant is 4/4 which is 100%.44
