Answer:Astronomers use a number of telescopes sensitive to different parts of the electromagnetic radiations to study objects in space
Explanation:
Answer:
adding nucleotides one by one
Explanation:
A typical primer is about five to ten nucleotides long. The primer primes DNA synthesis, i.e., gets it started. Once the RNA primer is in place, DNA polymerase "extends" it, adding nucleotides one by one to make a new DNA strand that's complementary to the template strand.
In fact, most of the chemical reactions that occur in life, involve substances that are dissolved in water. Without water, cells would not be able to carry out their normal functions and life could not exist. Water provides a habitat The hydrosphere<span> provides an </span>important<span> place for many animals and plants to live. Hope this helps :)</span>
Answer:
C. If isolated from a eukaryotic cell, mitochondria can no longer survive and reproduce on their own.
Explanation:
The endosymbiotic theory proposes that early eukaryotic cells evolved from endosymbiotic interactions among prokaryotic cells. This theory states that mitochondria and chloroplasts were once primitive bacterial cells that were ingested by large anaerobic prokaryotic cells, and then these cells benefited from living and working together. The most important lines of evidence that support this theory are that mitochondria and chloroplasts contain their own genetic material (circular DNA) and their own protein biosynthesis machinery (ribosomes).
