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.
Cells are combined in a structure called tissue wich have the same properties like the cells wich are formed by.
Answer:
Similarities between Mitochondria and Chloroplasts-
Both mitochondria and chloroplast consists of DNA , have two membranes, have fluids inside them and convert energy.
Difference between Mitochondria and Chloroplasts-
They have different number of compartments, have different functions, and are involved in different energy processes.
Explanation:
Difference in Mitochondria and Chloroplasts-
a) Chloroplast is found in plants and unicellular organism and Mitochondria is found all cells.
b) Chloroplast converts solar energy into chemical energy while Mitochondria converts one form of chemical energy into other form of chemical energy
c) Chloroplast is involved in photosynthesis while mitochondria is involved in cellular respiration.
d) Chloroplast has three parts i) Thylakoid ii) stroma and iii) granum while mitochondria has three parts i) Critsa ii) Matrix
Similarities between Mitochondria and Chloroplasts-
Both mitochondria and chloroplast consists of DNA , have two membranes, have fluids inside them and convert energy.
