Answer:

Ice cores drawn from Antarctica, Greenland, and tropical mountain glaciers proves that Earth's climate responds to changes in greenhouse gas levels. You can also find ANCIENT evidence in tree rings, coral reefs, layers of sedimentary rocks, and ocean sediments.

( re word it to however you would've said it if possible.)

Explanation:

I learned about this already, and had to do deep research when I did.

A researcher synthesizes a new molecule called inhibitor X that inhibits the activity of phosphofructokinase (PFK), the enzyme t
Oduvanchick [21]

Answer : The dissociation constant of the PFK‑inhibitor complex is, 5 µM

Explanation :

The expression for reversible competitive inhibition when apparent Km affected by addition of the inhibitor is:

K_m_a=K_m[1+\frac{I}{K_i}]

where,

K_m_a = apparent value = 52 µM

K_m = Michaelis–Menten constant = 40 µM

I = inhibitor concentration = 1.5 µM

K_i = dissociation constant of the PFK‑inhibitor complex

Now put all the given values in the above formula, we get:

52\mu M=40\mu M[1+\frac{1.5\mu M}{K_i}]

K_i=5\mu M

Therefore, the dissociation constant of the PFK‑inhibitor complex is, 5 µM

The law of_____
Marta_Voda [28]

Answer:

The correct answer is - segregation.

Explanation:

The law of segregation states that out of two factors or alleles of a gene located in an organism, only one allele or factor is distributed to each sperm cell or egg cell (gamete) randomly, So, the segregation of the alleles are random and only one allele is distributed to each gamete according to this law.

The law of segregation helps in making a different combination of alleles in a particular species or population and leads to variation in genetics. It makes sure that traits distribute to each generation randomly.
