Answer:
A) They share short homologies at their respective tips
Explanation:
The cells of human contain two types of chromosomes that is autosomal and sex chromosomes.
The 22 pairs of autosomal chromosomes in humans are formed by the pairing of these chromosomes during the meiotic phase via the formation of a structure called synaptonemal complex between homologous sequences.
However, the two types of sex chromosomes called X and Y are not similar in their length but they pair via the formation of synapse which involves very short homologous sequences called "pseudoautosomal regions". The formation of the synapse through this region is called the X-Y body.
Thus, Option-A is the correct answer.
Answer:
photosynthesis makes the glucose that is used in cellular respiration. while photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. (they are the opposite) it is the released oxygen that is used by us and most other organisms for cellular respiration.

Answer:
<em>A line graph</em>
Explanation:
A line graph would be the best type of graph to show changes over time. A line graph constitutes of a y-axis and an X- axis. The presence of the axis will make is easier to look at the height changes which occur over time. The y-axis of such a graph could show the height, the X axis of such a graph could show the time. Hence, a line graph could be the best one to represent such a change.
Answer:
C
Explanation:
If the frog has no predators, then it has nothing to keep it from breeding and thriving and so will multiply.
