The correct answer is "transmission electron microscope".

The transmission electron microscope can magnify the organelles of the cell clearly; as in light microscopes wherein most organelles cannot be visualized. TEM works by using a beam of electrons to pass through a specimen to make a clear image. Because of its superior magnification, mitochondrial defects can be visualized easily.

Attached is a sample picture of a transmission electron microscope image of a mitochondria.

Answer:

oxygen because that's one of the substance that plants produce.

You can also do this by the process of elimination. Knowing that atrazine impedes the production of substances in plants, we know that it can't be DNA and Phospholipid. Carbon Dioxide is used by plant, not produced; thus, oxygen is the answer.

Suppose the DNA sequence for the first message in Part B began with TGT CGA instead of TGA CGA. Would the message change? Why or
alexgriva [62]
The message would change because each base has a specific pair that it bonds with. So the original strand's matching sequence would be (ACT GCT) if they were to change the last letter of the first set of 3 numbers, it would be (ACA GCT), and you can see there is a difference in the first sequence of bases. Hope this helps (:

In the model of DNA, if the yellow peg represents cytosine, then the green peg MUST be A) adenine. B) guanine. C) thymine. D) ur
Montano1993 [528]

I suppose the yellow peg is facing the green peg, in which case the green peg must be guanine.

The bases are associated in pairs. In each pair there is always a purine associated with a pyrimidine. The association is by weak bonds: the hydrogen bonds, two bonds for an AT pair; three links for a GC pair. When we know the sequence of one strand we can deduce the sequence of the other strand. The two strands are oriented opposite to the 3 'and 5' ends (the strands are called antiparallel).

vodka [1.7K]

Answer:

Her minimum height must be 5'5" and her minimum weight must be 150 lb

Explanation:

The double red program is a program where red blood cells are donated by people . This red blood cells are used for treatment of patients that require red blood cells such as transplant of organs, transplant of tissues, treatment of cancer e.t.c.

Apheresis is a process whereby blood is collected or removed from the body and it undergoes the process of filtration into various components of the blood.

The machine that is used during apheresis collects the human blood and separates it into white blood cells, red blood cells and platelets.
