Answer:
E. Gene is amplified by multiplication of cloning host
Explanation:
PCR is a very powerful technique that can help us to amplify exponentially one gene from a very small sample of DNA.
As seen in the attached image, the process begins with a single DNA molecule, for the first cycle, that DNA molecule denaturalizes into two strands, the primers bind to their complementary sides and then the DNA polymerase builds the new DNA strands. The number of copies of the gene that can be obtained with each cycle are 2ⁿ copies, where n is the cycle number.
Answer:
The right side of your heart receives oxygen-poor blood from your veins and pumps it to your lungs, where it picks up oxygen and gets rid of carbon dioxide. The left side of your heart receives oxygen-rich blood from your lungs and pumps it through your arteries to the rest of your body.

Answer:
A potometer measures water loss from leaves. A bubble potometer measures the rate of water loss from a plant by transpiration. A weight photometer measures the amount of water lost by a plant through transpiration. The washing line method is used to prove that most water loss occurs from the lower surface of the leaf.
potometer' (from Greek ποτό = drunken, and μέτρο = measure), sometimes known as transpirometer, is a device used for measuring the rate of water uptake of a leafy shoot which is almost equal to the water lost through transpiration. The causes of water uptake are photosynthesis and transpiration
Answer:
25%
Explanation:
We have 2 independent genes with 2 alleles each: L/l and W/w
- W_: whiskers
- ww: no whiskers
- L_: long whiskers
- ll: short wiskers
Individuals with short whiskers will have the genotype <em>WWll </em>or <em>Wwll</em>.
<u>A cross between a rat heterozygous for both genes and a homozygous recessive rat is done:</u>
<h3>WwLl x wwll</h3>
-The homozygous rat will produce only <em>wl </em>gametes.
-The heterozygous rat will produce the following gametes: <em>WL</em>, <em>Wl</em>, <em>wL</em>, <em>wl</em>.
If you do a Punnett Square, you'll get that 25% of the offspring will be WwLl and will have short whiskers.
