Answer:

few predatory lacewings exist in the trees now because they were killed by the spray.

Explanation:

The spray that farmers used, as noted, also killed the populations of a predatory lacewing.

Due to this, few predatory lacewing remained that could not fully deal with the scale population.

This in turn led to the multiplication of scale now that their predators had been done away with.

OLEGan [10]

Answer:

The correct answer is option D which is release of water from the vacuoles.

liq [111]

Answer:

pulmonary circuit,  systemic circuit

Explanation:

The circulatory system consists of 2 circuits -

pulmonary circuit

systemic circuit.                  

The pulmonary circuit carries deoxygenated blood. The right auricle receives the impure blood by superior and inferior vena cava, then the blood enters the right ventricle. From the right ventricle, the deoxygenated blood moves to the lungs by the pulmonary artery.

In the lungs, the deoxygenated blood gets oxygenated and enters the left ventricle through pulmonary veins. The pureblood then passes into the left ventricle and then the ventricle pumps the oxygenated blood to different parts of the body. This blood passes to the body aways from the heart by aorta. When the blood gets deoxygenated, it again enters the right auricle. In this way, double circulation occurs and both types of blood do not mix together.
