Answer
Most of these techniques, including microarray analysis and reverse transcription polymerase chain reaction (RT-PCR), work by measuring mRNA levels. However, researchers can also analyze gene expression by directly measuring protein levels with a technique known as a Western blot.
Weathering breaks down and loosens the surface minerals of rock so they can be transported away by agents of erosion such as water, wind and ice. There are two types of weathering: mechanical and chemical.
The answer is Ocean Current s..
Answer:
Option C
Explanation:
There are cases when two organism of different species mate to produce offspring but that offspring is unable to reproduce further. Hence, such organisms do not belong to the same species. Thus, Option D is incorrect

Hence, option C is correct
<span>None of the above. All of the following affect
metabolism at some point in an individual's life. As a person ages, metabolic
rate generally slows down because of muscle tissue loss, and some hormonal and
neurological changes. Gender also affects metabolism because men are generally
larger in size than women that is why they tend to have faster metabolisms than
women. Genes or inherited traits from parents also affect metabolism, the rate
at which the body goes is dependent on inherited traits from parents, also the
diseases that come with abnormal genes can affect metabolism. Temperature can also
affect metabolism because the body adjusts to maintain its normal temperature
which can either increase or decrease metabolic rate.</span>
