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.
Answer:
Let's consider that red fruit is dominant over the yellow fruit.
<em>The phenotype of the red fruit of P1 will be red fruit and the genotype will be RR.</em>
<em>The phenotype of the yellow fruit of P1 will be yellow fruit and the genotype will be rr.</em>
To check the outcomes of the F1 generation, lets cross the P1 generation:
r r
R Rr Rr
R Rr Rr
<em>The results show that all the offsprings from the F1 generation will show the dominant phenotype which is red fruit and they will have Rr genotype. </em>

There are choices for this question namely:
a. Fungi rely on the wind to disperse their spores, whereas plants have multiple means of dispersal.
b. Spores do not have their own nutritional supply and often do not land in a suitable environment that provides nutrients.
c. Spores are produced asexually and so are less genetically robust.
d. Animals eat the developing mushrooms before they have a chance to mature.
The correct answer is that spores do not have their own nutritional supply and often do not land in a suitable environment that provides nutrients. Spores more often than not transported through air and lands randomly, usually in an unsuitable environment. Spores also do not have their own nutritional supply unlike seeds of plants which contain endosperm as nutrient source.
