Chromatids are only called as chromatids when they are sister chromatids, meaning that when chromosome have two double stranded DNA attached together, each of the double stranded DNA is a sister chromatid, and while the whole thing (the two sister chromatids that are attached together) is called a chromosome.
So after the DNA has been replicated, the chromosome consist of 2 sister chromatids, attached to each other at their centromere.
Overall, sister chromatid is one of the two double stranded DNA in a replicated chromosome, and chromosome is the whole "X" shape that we see. For example, in humans, after the S phase of interphase in the cell cycle, we have 46 chromosomes, with 92 chromatids, since each chromosome is an "X" shape, by having two sister chromatids.
Hope this helps!
Answer:

Explanation:
a. Found in small structures outside the nucleus of a cell and is inherited from the biological mother - Mitochondrial DNA
b. Hair’s form and structure Hair's morphology
c. Prints created when the finger touches a soft material like soap or putty - Plastic prints
d. Has studied bloodstains extensively and has offered a number of important observations about bloodstains - Herbert L. MacDonell.
e. Found in the nucleus of a cell and is inherited from both biological parents - Nuclear DNA
f. A set of cells that runs through a hair - medulla
The study of chemical reactions would be in chemistry and not biology so thats the answer
Answer:
There are two kinds of respiration: Aerobic and Anaerobic. ... Aerobic respiration takes place in the presence of oxygen, produces a large amount of energy. Carbon dioxide and water are produced as the waste products. Anaerobic respiration takes place without the use of oxygen, produces small amounts of energy.
