Answer:
D
Explanation:
Hormones are bigger than the cell pores hence cannot pass through the cell membrane to influence biochemical processes. Therefore, hormones (such as glucagon and insulin) bind onto receptors on the cell membrane, then transmembrane proteins, such as the G-protein, change conformation activating the secondary messengers inside of the cell. Cyclic- AMP is a major secondary messenger significant in activating protein kinases.
Answer:
The correct answer is b RNA polymerase is responsible for unwinding the DNA double helix and for catalyzing the formation of phosphodiester bond between nucleotides.
Explanation:
DNA double helix is unwound by the catalytic activity of helicase or dna B by using the energy derived from the hydrolysis of ATP.
RNA polymerase helps in the polymerization of nucleotides b the formation of phosphodiester linkage present in RNA.
Organisms
Explanation:
Come to think of it,what do organs form
The equation for density is:
where the mass is in grams and the volume is in 
.
We are given 4,000 kilograms, and we know that there are 1,000 grams in 1 kilogram, so we need to multiply to convert to grams:
We are also given 0.5 
, and we need to convert to . We know that there are 100 cm in 1 m, and since we are talking about cubic volume, we must also raise 100 to the 3rd power: 
. So now we know that there are 1,000,000 in 1 . We need to then multiply 1,000,000 cm by 0.5 in order to find the volume that was given in the question:
So now that we have the correct units, let's plug them into the equation:
So now we know that the density is 8g/cubic centimeter.
