What would cause rain showers to continue over a particular area for several days.

a. warm front.

b. low humidity.

c. a high pressure system

d. a stationary front

A stationary front

                          is the correct answer

The correct answer is option D. "A stationary front".

Explanation:

There are different types of front that could be formed when two or more large masses of warm air and cool air met. Among them, stationary front is the one that would cause rain showers to rain showers to continue over a particular area for several days. This type of front is formed when the masses of air that met do not have enough force to move one another, causing that the masses remain still or stationary for an undetermined period of time.

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!

the answer is sex-linked recessive.
