D) 1 and 4
Chromosomes are made up of DNA. DNA strands contain short segments called genes.
Answer:
1 kiloliter = 1,000,000 milliliters
45 × 1,000,000
45 KL = 45,000,000 ML
Endocytosis
Process by which the cell surrounds and takes particles into the cell
Exocytosis
Secretion of material out of the plasma membrane
Answer:
The right statement is " the Pathway A-C-D involves a catalyst and is faster than A-B-D"
Explanation:
Catalyst is a substance that increases the rate of a chemical reaction by lowering the activation energy Eₐ (i.e. by changing the reaction pathway), which Catalyst is not consumed in the catalyzed reaction and can continue to act repeatedly.
From the attached figure one can see that the path way A-C-D has different pathway and lower activation energy (Eₐ) than the pathway A-B-D, this means that the pathway A-C-D is a catalyzed pathway and it is faster than A-B-D.
So, the right statement is " the Pathway A-C-D involves a catalyst and is faster than A-B-D"
1 L ---------- 1000 mL
274 L ------- ??
274 x 1000 / 1 => 2,740 mL
hope this helps!
