Each chromosome consists of two identical “sister” chromatids. Each pair of chromatids is attached at an area called the centromere. Hope this helped :)
Because the group of small cells would have a greater surface area-to-volume ratio, so they are able to exchange materials with their surroundings more efficiently.
Answer: The correct answer is option C.
Explanation:
A false negative test is a diagnostic error in which a test shows absence of a disease even when a person is having a disease.
Similarly, in the given question a sample has anthrax spores; however, antibody test fails to show the presence of anthrax. Thus, it is a false negative.
In contrast, false positive error is the error in which the test shows the presence of disease even when a person is not suffering from it.
Sampling error is a statistical error.
Thus, the correct answer is option C.
Canal that connects the third and fourth ventricles is cerebral aqueduct (of Sylvius) canal.
<h3>What are the central canal?</h3>
The central canal, additionally known as the spinal foramen or ependymal canal, extends from the conus medullaris withinside the lumbar backbone to the caudal perspective of the fourth ventricle and is coated through a single layer of columnar ependymal cells . It represents the remnant of the lumen of the primitive neural tube.
The 3 ventricle is a slim, funnel-formed shape located among your proper and left thalamus, simply above your mind stem. The fourth ventricle is a diamond-formed shape that runs along your mind stem.
