Answer:
C. move proteins throughout the cell
Explanation:
My science teacher told me.
<span>Natural selection is when
species learn to adapt to their environment. They could (1) differential
reproduction, that is, not all organisms are able to reproduce to their fullest
capacity because nature cannot simply sustain it and (2) acquire genes, that is
heredity. Certain characteristics of organisms tend to survive if it continues
to strive. If it survives, this trait is passed down to the next generations
forgetting the other traits but only the one who could survive the environment.
Therefore it is true that <span>natural selection is when
‘organisms inherit advantageous traits, and tend to reproduce more successfully
than other organisms’</span></span>
Answer:
When phospholipids are mixed with water, they spontaneously rearrange themselves to form the lowest free-energy configuration. This means that the hydrophobic regions find ways to remove themselves from water, while the hydrophilic regions interact with water. The resulting structure is called a lipid bilayer.
Explanation:
B
Most of the time of the year, the sun is more or less overhead of the equator. This is why people living around the equatorial region observe the sun overhead across the year.
Explanation:
Therefore, the sun rays hit the equatorial region more or less perpendicularly, and the rays have a thinner atmosphere to travel through due to this angle.
Closer to the poles, the rays ‘hit’ the earth’s surface at an increasingly oblique angle and the rays have a longer atmosphere to travel (due to the spherical nature of the earth) hence losing most of its energy due to collisions with air molecules. This is why the sun fell less intense at the poles than at the equator.

.........by spacing, partitioning, or locating in an area not ABOVE food.
Locating a poisonous or toxic substance in an area that is above food is very dangerous. This is because, the substance may experience an accident which will make it to contaminate the food which are below it. For instance, the toxic substance may spill and contaminate the food that are stored below it. <span />
