Answer:
The third sentence is not correct. The correct statement would be as follows:
because the contents of the lumen of ER (or any other compartment) in the secretory or endocytic pathways never mix with the cytosol, Proteins that enter these pathways is never imported again.
Explanation:
During mitosis, specifically during prophase, when the nuclear envelope breaks down, or in other words, retracts from the chromatin, its content that is the membrane protein intermix with the ER membrane protein. However its content will always remain separated from that of the cytosol because of the presence of an intact membrane.
Answer:
Yes
Explanation:
Spiders, in fact, do taste, and also smell, through special sensory organs on their legs, as well as on their pedipalps. And they hear – or, more specifically, they sense vibrations – through hairs and tiny slits distributed over much of their body.
The value of the unknown number is 10.5.
Let the unknown number = x
When 20 is subtracted from the number and the result is squared which is equal to the square of the unknown number minus 20:
(x - 20)² = x² - 20
<em>expand the equation;</em>
x² - 40x + 400 = x² - 20
<em>collect similar terms together;</em>
x² - x² - 40x = -20 - 400
-40x = -420
Thus, the value of the unknown number is 10.5.
