If two diploid cells (2n) joined together in sexual reproduction, their fusion would produce a tetraploid zygote (4n). How do ce

lls that fuse together in sexual reproduction ensure the production of a diploid zygote instead of a tetraploid zygote?
A. The chromosomes fuse, which produces cells with half the number of chromosomes.
B. They first undergo meiosis, so these cells have only half the number of chromosomes.
C. The zygote splits in half, which produces two cells, each with half the number of chromosomes.
D. After fertilization, the cell undergoes meiosis, which reduces the number of chromosomes by half.

Different types of dominance
kiruha [24]
There are three types of dominance. Incomplete, complete, and co-dominance. Complete dominance is when the dominant trait completely masks the recessive. incomplete dominance is when the dominant allele doesn’t completely mask the recessive allele, sometimes resulting in blending. Co-dominance occurs when both alleles are expressed at the same time.

Which two (2) statements are correct examples of the “structure determines function” relationship among specialized cells in an
Nady [450]

Answer:

A and E are the correct.

Explanation:

Examples of the structures that determine function:

a) <u>Chloroplasts </u>only found in plant cells. They work to fix the CO2 in the presence of <u>light energy</u> (sunlight) and convert the reactants into <u>sugar molecules (carbohydrates</u>) that can be used by cells for metabolic functioning.

e) <u>Sperm</u> is the male reproductive cell. Motile sperm cells have a tail-like structure that typically <u>move via flagella</u> and requires a water medium in order to swim toward the egg <u>for fertilization</u>.

Other options are not correct because <u>they don't explain their function according to their structure</u>.
