Answer:
Primary active transport
Explanation:
Primary active transport is the transport in which molecules are moved against their gradient, with direct use of ATP as an energy source. Na/K pump is an example of primary active transport: Na ions are transported out of cell, K ions are moved into the cell. This pumps maintain concentrations of those ions and also creates voltage across the cell membrane, which can be used for the secondary active transport of other molecules (e.g. glucose).
The parental phenotype is the mother's free earlobes (Ff) and the father's nonfree earlobes (ff).
<h3>What genotype and phenotype?</h3>
The genotype refers to the information present in an individual's genome. Unlike the phenotype, it is not observable and rarely changes. The phenotype, in turn, depends on a combination between our genotype and the environment and can be defined as the observable characteristics of an individual.
With this information, we can conclude that the parental phenotype is the mother's free earlobes (Ff) and the father's nonfree earlobes (ff).

During the winter season, the tree branches get dormant.
<u>Explanation:</u>
As the winter season starts, many plants show very slower metabolism that is the growth of the plants become very slow.
During the winter, there is very low amount of sunlight that the plants receive and so the synthesis of chlorophyll by the plants also in very small amount, and so there is least amount of sugar to metabolize by means of a slower Photosynthesis.
These tree branches become dormant during winter season, and it is mostly covered with the scales.
The breakup of the supercontinent of Rodinia created new mountains and land surface for new organisms to live on.
<h3>What are supercontinents?</h3>
Supercontinents are large continents which are composed of other continental blocks of the earth.
One of the supercontinents was Supercontinent Rodinia.
The breakup of the supercontinent of Rodinia created new mountains providing a land surface for organisms crawling out of the sea to live on.
In conclusion, supercontinents are composed of fused continental blocks.
