Answer:
About 18%
Explanation:
Cytosine matches with Guanine nitrogen bases so,
32% + 32%= 64%
The remaining 36% goes to Adenine and Thymine
36/2= 18
So, about 18% of the nitrogen bases in the sample of DNA is Thymine

Explanation:
The sub-phyla that would be placed directly around the Craniata are Urochordata and the Cephalochordata.
Urochordates are small marine animals with larvae that swim freely and adults attach themselves to the ocean floor. They are commonly known as tunicates, differ from other chordate subphyla in that the adult form has no notochord, nerve cord,or tail. Cephalochordates or lancelets have notochord extends from near the tip of the tail to well into the anterior of the body. They do not have the braincase, or cranium, of a vertebrate, lancelets are often called acraniates.
Answer:
Are made of smooth endoplasmic reticulum.
Explanation:
The endoplasmic reticulum is one of the most important cell organelle that is present in continuous with nuclear envelope. The two types of endoplamsic reticulum are smooth endoplasmic reticulum and rough endoplasmic reticulum.
Terminal cisterns are the large extended area of the sarcoplasmic reticulum that may surrounds the transverse tubules. They store the calcium in the muscle cells. The terminal cisterns are derived from the smooth endoplasmic reticulum and shows some structural similarity as well.
Thus, the correct answer is option (a).
Answer:
46
Explanation:
mitosis creates identical cells so if the mother cell has 46 chromosomes then so will the daughter cells that were formed after mitosis
