Explanation

Pteridophytes, such as ferns, are vascular plants that reproduce via spores rather than seeds.

They have a well-developed vascular system for transporting water and nutrients, distinguishing them from non-vascular bryophytes.

Explanation

Phenotype refers to an individual's observable traits, such as height, eye color and blood type

A person's phenotype is determined by both their genomic makeup (genotype) and environmental factors.

Explanation

When crossing CC (homozygous dominant) with Cc (heterozygous), the possible genotypes of the offspring are:

CC (from C and C)

Cc (from C and c)

The genotype distribution is:

CC: 50% (or 1/2)

Cc: 50% (or 1/2)

So, the proportion of homozygous dominant (CC) offspring is 1/2.

Explanation

Potassium ions play a crucial role in the conduction of nerve impulses.

They help in the repolarization phase of the action potential,

Allowing the nerve cell to reset its membrane potential after the transmission of an impulse

Explanation

Bryophytes are a group of non-vascular plants, which include mosses, liverworts, and hornworts.

They are characterized by their lack of vascular tissue (xylem and phloem) and reproduce via spores instead of seeds.
