What purpose does a female pine cone serve?
A.
It protects the seed until it matures.
B.
It makes food for the adult plant.
C.
It allows for photosynthesis to occur.
D.
It acts as an object to attract birds.
E.
It serves as an ornamental object on the tree

Answers

Answer:

It protects the seed until it matures

Explanation:

Pine cones don't have chroloplasts so they can't produce photosynthesis. Pine cones are rough and spiky and birds wouldn't want to put something rough and spiky in their nests where they raise their young. But it is rough and spiky enough to protect the seed until it's been dispered far enough to break open the shell and start growing.

Answer:

It protects the seed until it matures.

2. When calculating the recombinant frequency of two genes, what is
the most important factor?
O A. how close they are to each other
OB. how close they are to the end of the chromosome
Oc. whether they are on the X or Y chromosome
OD. which one is higher on the chromosome

Answers

Answer:

Explanation:

The most important factor is how close they are to each other.

• The physical swapping of the pieces of chromosomes at the time of meiosis is responsible for the recombination of genes.

• The swapping can take place anywhere along the length of the chromosome, that is, in any part of the gene.

• The recombination frequency between the two genes is equivalent to the ratio of offspring in which the event of recombination took place between the two genes at the time of meiosis.

• The determination of the recombination frequency is done by the frequency of the recombination events between the two genes in meiosis.

• The more the physical distance between the two genes, the more is the probability that the recombination take place during any meiosis event.

Thus, the correct answer is option A.
