Answer: The answer is (D) prevent the passge of certian molecules into the cell.
Step-by-step explanation: We have four option out of which one describes the functions of protein present in the phospholipid bilayer in the cell membrane.
Phospholipid bilayers are critical components of cell membranes. Its function is to act as a barrier to the passage of molecules and ions into and out of the cell. It allows selective substances and molecules to come in and go out of the membrane.
Thus, the correct option is (D).
Well, as far as I can tell, the mean (average) is the best representation of the data because there is no outlier (a number a lot higher or lower than the rest of the numbers that throws the data off).
Answer:
Option B. -j = -h/-k is not correct
Step-by-step explanation:
As from the given scenario both the negative signs will be cancelled out giving positive j : -h/-k = -j
First option has: -j = -h/k In this case also the negative sign from both sides would be cancelled out.
Second option has: -h/-k = -j In this case negative signs cannot be cancelled out.
Third option has: h/-k = -j , negative sign would be cancelled from both sides.
Fourth option has: h/k = j , no negative sign on either side.

Click on the second choice, the 3x one
Answer:
y = -2x + 1.
Step-by-step explanation:
2y = x - 1
y = 1/2y - 1/2
If line X is perpendicular to line Y (the line where y = 1/2y - 1/2), the slope will be the negative reciprocal of line Y. That means that there will be a negative sign instead of positive, and the 1/2 will be flipped to become 2/1, which is 2.
So, the slope will be -2.
We now have y = -2x + c.
To find c, simply put in -1 for x and 3 for y.
3 = -2 * -1 + c
c + 2 * 1 = 3
c + 2 = 3
c = 1
So, the equation of the line is y = -2x + 1.
Hope this helps!
