Answer:
4) Some people consider human genetic experiments
unethical.
Explanation:
1) Humans have DNA that is structurally very different from
other mammals.
2) Cloning can only he performed on animals that normally
reproduce asexually.
3) Human genes are made of too many different types of
simple sugars.
4) Some people consider human genetic experiments
unethical.
The statement that provides the most likely reason that a human has not yet been cloned is that some people consider human genetic experiment unethical.
<em>Option 1 is incorrect because human DNA is similar in structure to other living organisms with components such as a phosphate group, a deoxyribose sugar and purine/pyrimidine bases.</em>
<em>Option 2 is incorrect because cloning is not limited to asexually reproducing organisms only. Sheep, for example, produces only sexually and has been successfully been cloned.</em>
<em>Option 3 is incorrect because human genes, just like every other organisms is consist of DNA with deoxyribose pentose sugar being one of the components. The situation of too many different types of simple sugars doe not arise.</em>
The correct option is 4.
Earthworms have two muscles which is used in locomotion. Both muscles are circular and longitudinal (inner layer of the series of muscles). The diameter of the earthworms body is reduced when the circular muscles are contracted which makes them appear to be thin. The worm appears short when the longitudinal muscles contract thus, its length is reduced.
Amphioxus on the other hand, have two unique muscle fiber types. This includes deep fibers and smaller but mitochondria-rich superficial fibers. E<span>ach of which has its own innervation.</span>
