Vascular tissue
Of course plants don't have hearts, but they do have vessels which transport water, minerals, and nutrients through the plant. These vessels are the vascular tissue.
Well, in a way it is true, as, chloroplasts are the reason why plants photosynthesize. So, with the photosynthesis, it releases oxygen, which is the power generator for life on Earth, as we breathe in oxygen.
Answer:
C. He forgot to add primers.
Explanation:
The major components of a PCR include:
- A sample DNA which is the DNA that needs to be amplified.
- A DNA polymerase, an enzyme that synthesizes new DNA strands from the sample DNA.
- A primer which represents the starting sequence for the new strand of DNA to be synthesized.
- Free nucleotides in form of Deoxynucleoside triphosphates (dNTPs)
<em>The graduate student forgot to add primers which are essential as a starting point on which the synthesis of new DNA strand is based. DNA ligase is not needed for PCR, but during DNA replication.</em>
The correct option is C.
A because if you look it up phytoplankton does uses photosynthesis to produce food.
Answer:
Unlike a virus, a retrovirus inserts its genome into the host's genome. In this way, the retrovirus becomes part of your cells.
