Answer:
<em><u>H1: false, the observations of the molecules do not support the hypothesis...</u></em>
Explanation:
The cell membrane is comprised of a phospholipid bilayer, proteins, and cholesterol. These components help the membrane to maintain its selective permeability and concentration of solutes and water.
The lipid molecules have polar hydrophilic heads and hydrophobic tails. These only readily allow for the movement of small non polar molecules. Other substances, like charged ions and large molecules require transport proteins to move in and out of the cell. Hypothesis: H+ is small and should be able to move freely through the membrane, While glucose is large and cannot move freely
- Observing H+, despite being very small these cannot easily pass through the membrane. They require transport proteins called channels for their free movement or passive movement across the membrane.
- For glucose, these molecules pass through specialized channels in facilitated diffusion. They move down their concentration gradient into the cell. To move out of the cell against its concentration gradient glucose requires ATP for active transport.
- Cortisol, is a large steroid hormone, taken into the cell by simple diffusion across the lipid membrane, down its concentration gradient.
Answer:
The formation of large molecules takes place by the addition of smaller molecules together. These small molecules are called as monomers and larger molecule formed by the addition of these monomers are called as polymer. The process of formation of polymer from monomers is known as polymerization.

The answer is steep mountains due to it being rocks wind and rain can erode it more
<span>When one organism eats another organism, it gets about 10% of its energy.
For example...the grass has 4000 units of energy.
When the mouse eats the grass, the mouse gets 10% of the grass' energy.
10% of 4000 is 400.
The mouse gets 400 units of energy, from eating the grass.
You get it?
The owl eats the mouse.
If the mouse has 400 units of energy, how many units will the owl get?
The bobcat eats the owl.
How many units of energy will the bobcat get?</span>
