Answer:
D. 91.22 mL
Explanation:
Boyle's Law P₁V₁ = P₂V₂
(50mmHg)(277.3mL) = (152mmHg)(V₂)
V₂ = 13865/152mmHg
V₂ = 91.2170526 mL = 91.22 mL
Believe it or not it’s a pure substance, two hydrogen atoms combine with one oxygen atom chemically, forming a new substance that has properties different from hydrogen alone or oxygen alone.
Answer:
13 chromosomes, meiosis
Explanation:
the sperm cell contributes half of the chromosome in an offspring while the egg cells contributes the other half. Hence, the sperm cell has half of 26, 13. This process is called meiosis. Meiosis is when one cell undergoes cell division twice, thus creating 4 new cells. Each of these 4 new cells have half the amount of chromosomes as the original cell.
The two strands must be separated like the two sides of a zipper, by breaking the weak hydrogen bonds that link the paired bases.
<u>Explanation:</u>
- A double helix structure formed by two polypeptide chains is separated like the two sides of a zipper. A zipper is formed by breaking the weak hydrogen bonds that link the paired bases. During replication, an enzyme "Helicase" travels down the DNA and splits the chain and it forms 2 separate strands.
- The two DNA strand which has the same sequence must be separated like the two sides of a zipper by breaking weak hydrogen bases. During base pair-rule, the strand are unzipped and each strands is copied.
