Answer:
1.Vascular tube is used for vascular surgery and is very small in size with very small diameter and thickness,thus a little change in environment can also affect there result.
2.When testing for tension in the polymer it is very important to consider the strain rate as the increase in strain can cause the material to break.Therefore not only tension test but also strain test is required.
Explanation:
Answer:
a) Genes b and c are farthest apart.
Explanation:
Transformation occurs when a competent bacteria cell takes up genetic material from the environment. Usually a donor cell donates its gene fragment which is then incorporated into the chromosome or plasmid of recipient bacterial cell.
Cotransformation occurs when two genes are taken up together by the recipient. The closer the genes lie to each other, more are the chances of them being taken up together. Contransformation frequency will be higher if two genes are close to each other. Here, cotransformation frequencies between three genes are given. Amongst them, the lowest frequency is 0.0064% which is present between gene b and c. Hence, gene b and c are the farthest apart.
If a scientist makes the argument that she has found DNA evidence that shows that evolution does not exist, the evidence would be the weak physical similarities among closely related organism and also among distantly related.
