Answer:
<em>The correct option is D) The expression of certain genes is affected by temperature.</em>
Explanation:
There are various factors which control the regulation of a gene. Temperature can be a regulatory factor for certain genes.
Probably, during the warm temperatures, the proteins regulating the fur colour to become reddish brown become activate these genes. As a result, the fur becomes evident.
In the winter, the enzymes controlling the fur might become degraded. A s a result, the genes are not able to express themselves. Hence, a white coat occurs.
Answer:
Earthquake and tsunami warning systems both monitor the same thing: seismic waves. Seismic data takes the Earth's pulse directly, so when the earth shakes, we get immediate feedback. If all goes well, we have enough time to run.
Explanation:
An earthquake is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves.
A tsunami or tidal wave is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake.
Answer:
It's C
Explanation:
What are coenzymes? Vitamins are essential to the survival of organisms because vitamins usually function as these. What is lipase? Of protease is an enzyme that catalyzes reactions involving proteins, whereas this term can be used for enzymes that catalyze fashions involving fats, oils, and waxes.
I believe the correct answer is mRNA. Dicer is a part of RNase III which leaves double stranded RNA and pre-microRNA into short double stranded RNA fragments called small interfering RNA and microRNA respectively. The Dicer facilitates the activation of RNA induced silencing complex (RISC), which are essential for RNA interference. The RISC has a catalytic component argonate, which is an endonuclease capable of degrading mRNA. siRNAs are specfic to the mRNA sequence unlike miRNAs which are not completely complementary to the mRNA sequence.
