Answer:
There is no diagram but
It would be A if you were looking at the endoplasmic reticulum (ER).
It would be B if you were looking at a mitochondrion.
I do not remember what C is, so if it is not the ER, Golgi apparatus, or the mitochondrion, it is most likely C.
It would be D if you were looking at a Golgi apparatus
When you go one way and make someone else go the other way
Answer: The blank can be filled correctly by "if the seeds contain the gene or allele responsible for large size of the tomatoes"
Explanation:
In plants also, characters or traits of characters are defined by genes. Different alleles produce different traits of the same character.
For example, in classic Mendelian genetics, T was the allele responsible for tall plant trait while t was the responsible for dwarf trait.
Similarly, there would be a gene(s) responsible for size of the tomatoes. In addition, seeds are the products of sexual reproduction of plants. So, they may carry genetic combination different from parent plants (due to meiosis, crossing over, independent assortment, et cetera).
So, if the seed contains the gene or allele responsible for large size of tomatoes then only they will produce same kind of tomatoes.
Answer:
The second pair of grandparents have approximately 12 to 19 boys as grandchildren.
Explanation:
The probability of a grandchild being a girl or a boy is same, i.e., 
.
The first pair of grandparents have 4 grandchildren.
The second pair of grandparents have 32 grandchildren.
If first pair of grandparents have between 40% to 60% boys as grandchildren then the number of boys are in the limit,
Thus, the first pair of grandparents have approximately 2 to 3 boys as grandchildren.
If second pair of grandparents have between 40% to 60% boys as grandchildren then the number of boys are in the limit,
Thus, the second pair of grandparents have approximately 12 to 19 boys as grandchildren.
So, it is clear that the second pair of grandparents are more likely to have between 40% and 60% boys as grandchildren.
Also according to the law of large numbers as the sample size increases the probability of an event gets closer to the theoretical probability.
