Answer:
(1) In order to move your muscles need to ligaments. 
(2) Joint holds bones together. 
(3) Tendon connects bones to muscles.
Explanation: 
Ligaments are strong bands of tissue which are responsible for the movement of bones in the body. Joints are the place or point where two bones are attached. Tendons are responsible for connecting muscles of the body to the bones.

Answer:
The answer is D.
Explanation:
The example given in the question is an example of gene flow which can be described as the movement of specific genes from the the gene pool population to population.
The act of catching the bigger fish and letting the smaller ones escape is changing the gene pool of the North East Arctic Cod and causing the next generations to have smaller and smaller sizes which is given as the genetic variation decrease due to gene flow.
I hope this answer helps.

Answer:
If the cancer cell's DNA is sequenced than the anticipated results will be that the cytosines in or close to the promoter region will get methylated. It has been stated that in the cancer cells one allele of p53 is mutated and the other allele, however, of exhibiting an intact promoter, does not express the protein.  
Thus, it shows that the expression in the other allele gets suppressed by methylation rather than by mutation. Methylation generally takes place in CpG islands in or close to the promoter region and therefore inhibits transcription.
