i dont understand what you are saying but water gets evaporated from the oceans due to the suns warmth all the water vapors condense, once the clouds get too heavy and there are too many water vapors in the cloud for it to handle, it percipitates (rains)
Answer:
As the bubble is a spherical entity, the probability of total internal reflection from the watery films is high due to its curvature. As a result, most of the light rays get reflected and therefore the air bubble shines brightly with some sparkling in water
The above is an example of a polygenic trait. This implies every prevailing allele "includes" to the declaration of the following predominant allele. As a rule, qualities are polygenic when there is a wide variety in the characteristic. For instance, people can be a wide range of sizes. Stature is a polygenic characteristic, controlled by no less than three qualities with six alleles.
Answer:
D. Molecules called pumps function to control active transport.
Explanation:
Active transport is one of the two types of transport (the other being passive transport). It is the type of transport in which substances move against their concentration gradient i.e. from a lower concentration to a higher concentration. Hence, due to this, energy input in form of ATP is required by the cell.
However, the process of active transport makes use of certain molecules called PUMPS to control it. The pumps moves ions/molecules against their concentration gradient. An example is the sodium-pottasium pump which moves sodium ions from a region of low conc. to a region of high conc.
The variable that researchers manipulate is the independent variable.
The reason for this is because in experiments different manipulations are often introduced. The sole purpose of these manipulations is to see whether they will affect our independent variable and if they will change its value.
