What process is responsible for producing the 2n zygote

fertilization

Explanation:

Fertilization is the process whereby the nucleus of a male gamete fuses with the nucleus of a female gamete to a form a diploid zygote. This occurs in the oviduct following copulation. Both the male and female gamete are haploid. They contain half the number of chromosomes after successive meiosis.

When the sperm comes into contact with the egg, the acrosome bursts open and releases lytic enzymes which dissolve the egg membrane. Inside the cytoplasm of the ovum the head of the sperm releases haploid male nucleus.

what statement best describes the difference between the sympathetic and parasympathetic nervous systems?

the sympathetic nervous system prepares the body for intense physical activity and is often referred to as the fight-or-flight response. the parasympathetic nervous system has almost the exact opposite effect and relaxes the body and inhibits or slows many high energy functions.

to figure the total magnification of an image that you are viewing through the microscope is really quite simple. to get the total magnification take the power of the objective (4x, 10x, 40x) and multiply by the power of the eyepiece, (usually 10x)
