There are only two things you need to know.
<span>1. A probe works by base pairing to the DNA strand, so its sequence must be complementary to the DNA sequence of interest. </span>
<span>2. You need to know which strand is the strand of interest. </span>
<span>To tell the truth I'm not sure about the answer to question 2. Which one is the template strand? Either can be used as the template. I *think* the top strand is typically used as the template, but usually it's specified. Perhaps it's specified somewhere in your question or previously. </span>
<span>Anyway once you find your template strand, an mRNA was made from it so its sequence is complementary to the template strand. Then a probe was made using the mRNA as a template, so it is complementary to the mRNA, which in turn is complementary to the template strand (on the original DNA). So essentially what this means is that the probe will have the same sequence as the DNA template strand (the one you used to make the mRNA).</span>
The correct answer is option C, The vary from ecosystem to ecosystem
The factors which limitizes the growth of an ecosystem are called limiting factor. The four common limiting factors are food, water, shelter and space which is same for all organisms while there are some abiotic factors that limit ecosystem growth such as temperature, precipitation, sunlight, soil configuration, and soil nutrients which are also same. But some time there can be special factors which may limitise the ecosystem growth and thus option C is the apt answer
Answer:
B. Different genes are expressed due to their environment.
Explanation:
I think it's this one because it makes the most sense, but I'm still not sure sorry
Answer:
Lava defines the external state of magma on the surface of the Earth. Magma is what describes the internal molten rock and minerals of Earth.
