1.) erosions is a change in the weather
There are two basic types of ER. Both rough ER and smooth ER have the same types of membranes but they have different shapes. Rough ER looks like sheets or disks of bumpy membranes while smooth ER looks more like tubes. Rough ER is called rough because it has ribosomes attached to its surface.
<span>The double membranes of smooth and rough ER form sacs called </span>cisternae. Protein molecules are synthesized and collected in the cisternal space/lumen<span>. When enough proteins have been synthesized, they collect and are pinched off in </span>vesicles<span>. The vesicles often move to the Golgi apparatus for additional protein packaging and distribution. </span>
Smooth ER (SER)<span> acts as a storage organelle. It is important in the creation and storage of lipids and </span>steroids<span>. Steroids are a type of ringed organic molecule used for many purposes in an organism. They are not always about building the muscle mass of a weight lifter. Cells in your body that release oils also have more SER than most cells. </span><span>

Answer:
Option 2
Explanation:
I did not see the video referenced, but an invasive species is not always brought by people. Furthermore generally there are no limiting factors because it has no natural predators in the environment and often uses up all the resources in that particular environment. Hope this helps!
Answer:
the answer is c just did it on edg and got it right
Explanation:
Answer:
a. allow a variety of molecules to cross the cytoplasmic membrane
Explanation:
The cells have different molecules in its membrane. As a membrane the main function of it is to regulate the income and outcome of substances that the cell needs or the cell has like some wastes.
Some of these molecules can be some proteins like the permeases, that is going to regulate the solutes that can enter the cell, but since they are non specific, that means that can not make the difference among one carbohydrate and another (as an example).
