Answer:
(a) 21% of the human genome is comprised of G.
(b) 29% of the human genome is comprised of T.
(c) 29% of the human genome is comprised of A.
Explanation:
According to Chargaff's rule, a DNA molecule has the same amount of pyrimidines (T and C) as purines (A and G), and G pairs with C and A pairs with T.
If 21% of the genome contains C, then 21% also contains G.
Therefore 21% + 21% = 42% of the genome is comprised of G+C.
The other 58% is comprised of A+T, and because they pair with each other, 29% will correspond to A and 29% will correspond to T,
Answer:
475
Explanation:
The strand is only made up of Adenine, Thymine, Cytosine and Guanine. There will be the same number of Adenine as there are Thymine and the same number of Cytosine as there are Guanine.
We know there are 425 Thymine. This means there are also 425 Adenine. Therefore, you would subtract 850 (425x2) from 1800 to find the amount of Cytosine and Guanine left, which is 950.
Out of the 950, half will be Cytosine and half Guanine. 950/2 is 475.
Answer:
There are limits on the size of structures such as cells that depend on diffusion to interact with the environment.
Explanation:
There are limits on the size of structures such as cells that depend on diffusion to interact with the environment. As cell volume increases, the area of the cell membrane does not keep relative pace. ... So the reason there are no huge cells is that therer is a limit to their size because of the surface area/volume ratio.
Answer:
Population Growth: Exponential
Subsistence Growth: Arithmetic
Explanation:
Thomas Malthus was kind of a pessimist. His theory says basically we will run out of food and die. People grow like this equation: 2^x while food grows like this equation: 2x. So if you understand that it explains it.
PS: is this a biology question??? i remember learning this in AP Human Geography
False, most of the nutrients are absorbed in our stomach. The intestines are mainly for waste.
