Option D
polymerase chain reaction (PCR) do Makes more copies of a sample of DNA
<u>Explanation:</u>
A procedure to create several portraits of a distinct DNA section is termed as Polymerase chain reaction. In other words, it is a lab routine handled to compose various representations of a portion of DNA. PCR is extremely explicit and can be utilized to increase, or model, a particular DNA destination from a hybrid of DNA particles.
In PCR, the effect is regularly cycled within a range of temperature variations, which deduct countless models of the destination range to be exhibited. PCR intends to obtain sufficient of the objective DNA region that it can be examined or applied in some other way.
To give a direct answer, I’d have to know what gene we were looking at. However, in a general sense, when a genotype has two capital letters, it means that it’s homozygous dominant. Take for example:
R= tall stalk
r= short stalk
The uppercase R is a dominant allele, which means if the plant has the gene with this in it (RR or Rr) then it will have that trait. If it has two lowercase letters (rr) then it will be the recessive trait.
Using this example, RR would be the tall stalk. For whatever your question is, the dominant phenotype would be the answer.
Answer:
The process of photosynthesis is energy-storing because the process converts light energy into chemical energy, which is stored in the bonds of glucose.
Answer:
The following are accurate about earthquakes which occur during the formation of a chain of Islands and seamounts by hotspots:
- Earthquakes occur along fault lines within volcanoes formed by the hotspot.
- Earthquakes occur along fault lines during plate movements.
- Earthquakes occur when Earth’s crust bends under the weight of islands formed by the hotspot.
Explanation:
Answer:
The amount of fossil fuels formed is much less than the amount used.
Explanation:
Fossil fuels, which include petroleum, coal, natural gas etc are an example of non-renewable sources of energy. They are termed non-renewable because they are sources that gets exhausted quickly without replenishment.
One of the characteristics of non-renewable sources of energy is that they get exhausted faster than they can be produced. Hence, regarding fossil fuels as an example of non-renewable source of energy, this means that the amount of fossil fuels formed is much less than the amount used.
