Answer:
Phospholipid bilayer determinates which molecules can enter or exit the cell so its purpose is to be a checker in the middle. Cell membrane determinates the structure of the cell and it is the connection to the rest that happens in a cell.
Explanation:
Molecules can move in 2 ways: passive and active.
The only difference is the energy that is needed to do the movement.
In passive mechanisms, energy is not used, while in active transport, energy is needed. Diffusion or passive transport are moving the concentration from hight to low so the energy is not necessary. Active transport moves from low to a high concentration and it uses metabolic energy.
The answer is; A
This model hypothesizes how life started during the early conditions of the earth which were hot and filled with greenhouse gases in its atmosphere about 4 billion years ago. It is explained by the theory of spontaneous generation where organic molecules were created from inorganic molecules spurred from energy from lightning. These organic molecules filled the water bodies and chemically arranged themselves, over time, into primordial life.
It depends on where your going and how many people are going to the trip. But in my opinion I think about 3 times because you need to make stops when you need to use the restroom and when your hungry.
Sorry if I am not right :(
I hope I helped you have a great day :)
Answer:
26%
Explanation:
if cytosine makes up 24%, then guanine also makes up 24%.
add these to get 48%.
subtract that from 100% to get a remaining 52%
then split the 52% between adenine and thymine to tell you that 26% is thymine
