Answer:
Phospholipid bilayer.
Explanation:
The plasma membrane (also known as the cell membrane or cytoplasmic membrane) is defined as a biological membrane that separates the interiors of a cell from its external environment.
The plasma membrane has a function that protects the cell from its external environment, mediates cellular transport, and transmits cellular signals.
It is composed of a lipids bilayer (phospholipids and cholesterol), (phospholipid is a lipid made of glycerol, two fatty acid tails, and a phosphate-linked head group) with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules which hence, regulates the movement of substances in and out of cells. Plasma membranes is very flexible in order to allow cells change form example, red blood cells change shape as they pass through narrow capillaries.
Answer:
Both stated that humans should be studied as individuals.
Both stated that evolution occurs in an individual’s lifetime.
Explanation:
I don't no if it is right.
Answer:
3- As cells get larger, the volume increases more than the surface area
Explanation:
As a cell develops, it grows larger and extends the cell membrane. Sadly, the volume rises greater than that of the surface area, and therefore the relative surface area usable to transfer resources to a unit cell volume declines gradually.
Answer:
- <u>The hours are the independent variable.</u>
- <u>The wages/wk earned are ( $11/hr )x( hrs worked )
. This is the dependent variable ( depends on hours worked )
.</u>
- <u>The domain is 0 to 30
</u>
- <u>The range is 0 to 330
</u>
Explanation:
<em>The hours are the independent variable and should be plotted on the x-axis
.</em>
<em>The wages/wk earned are ( $11/hr )x( hrs worked )
. This is the dependent variable ( depends on hours worked ) and should be plotted on the y-axis
</em>
<em>---------------
</em>
<em>Let +W+ = wages/wk earned
</em>
<em></em>
<em>Let +h+ = hours/wk worked
</em>
<em>The equation is:
</em>
<em>+W+=+11h+
</em>
<em>The domain is 0 to 30
</em>
<em>( no hrs worked to 30 hrs worked )
</em>
<em>The range is 0 to 330
</em>
<em>( no wages eared to +11%2A30+=+330+ earned )</em>
