Answer:

Polygenic trait

Explanation:

Polygenic trait is a trait that is determined and controlled by more than one gene. Due to involvement of multiple genes, the genes that control them maybe located near them or on separate chromosomes. Some examples of polygenic traits are eye color, height and skin color. These traits display a continuous distribution.

Answer:

Answer is option A.

Orchid bees are to Brazil nut trees as breezes are to pine trees.

Explanation:

In Brazil nut trees, the female orchid bees act as pollinators that help in pollination. In pine trees, wind or breeze helps in pollination.

Pine trees are gymnosperms and so they do not have flowers to attract pollinators like bees or butterflies or birds. They are wind-pollinated. Pine trees are monoecious i.e., both male and female reproductive structures (pine cones) are present on the same tree.

The male cones (catkins) produce pollen grains that are lightweight, less sticky and have air bladders or small wing-like structures. As a result of these features, the pollen grains can be easily carried and dispersed by the breeze. In order to prevent self pollination (pollen falling on the female cones of the same tree), the male cones are normally located on the lower branches of the pine tree.  

The female cones are located on the upper branches of the tree and the center of the cone contains eggs or ovules. The pollen grains that are carried by the wind, fall on the female cone of another pine tree. Each pollen grain grows a pollen tube into the center of the cone and the nucleus cell of the pollen travels through the tube and reaches the egg, where it combines with the egg to form an embryo. The embryo eventually grows into a seed. The seeds of pine trees are then dispersed by wind or animals such as squirrels.

iren [92.7K]

ATPase is the enzyme which is required to create ATP and is denoted as option B.

<h3>What is ATPase?</h3>

This type of enzyme is found in the mitochondrion and catalyzes the formation of ATP which provides energy to cells.

The ATP which is referred to as adenosine triphosphate is formed from the molecules known as ADP and inorganic phosphate which are present in the body cells. This ensures that the daily energy needs of the body are met.
