Answer:
Option 3, Chromatids remain attached to one another until anaphase
Explanation:
Centromere lies at the center, end or other points of the chromosome and joins the two sister chromatids. During cell division, the spindle fibers attaches at the centromere and detaches the chromosomes during the anaphase of the cell division to ensure that each daughter cell gets equal number of chromosomes at the end of mitosis. Centromere plays an essential role in the separation of chromosomes.
Hence, option 3 is correct
Answer: The correct answer for the blank is-
Energy is released from ATP ( adenosine triphosphate) when high energy phosphoanhydride bond ( present between two phosphate) is broken down or hydrolyzed.
This results in the formation of ADP ( adenosine diphosphate) and Pi ( inorganic phosphate).
Therefore, hydrolysis of ATP releases energy.
The parietal bone are large paired bones form most of the lateral and superior walls of the cranial vault (calvaria).
<h3>What is a Bone?</h3>
These are tissues which contain high amounts of calcium and form the main component of the skeleton. They also helps to provide structural integrity and rigidity to parts of the body and protect vital organs such as the heart, brain etc of the body from any form of external stimuli encountered.
The parietal bone is attached by a fibrous joint and forms part of the roof and sides of the cranium. They are also involved in the formation of most of the lateral and superior walls of the cranial vault (calvaria) present in the body system.
This is therefore the reason why parietal bone was chosen as the most appropriate choice.
