Describe the structure of the cell membrane and explain what materials enter and leave the cell and how each transport method is
Nutka1998 [239]
THE STRUCTURE OF THE CELL MEMBRANE
the cell membrane is a thin layer of a partially permable membrane. That protects the cell's organelles and helps to maintain the shape of the cell.
WHAT MATERIALS ENTER OR LEAVE THE CELL MEMBRANE.
since the cell membrane is partially permable, that it only allows some materials to pass through it only nutrients that need to be metabolized or neede by the cell is allowed or permitted to go in the cell either by diffusion or osmosis.
HOW IE ONE METHOD DIFFRENT FROM THE OTHER?
since diffrent materials that go in the cell have different concentrations, sizes, and weights, the method by which they go into the cell will definately be diffrent materials with larger molecules use the osmosis method to go in the cell, while materials with smaller molecules use the diffusion method.

In which type of human cell(s) would 46 chromosomes be located? Select all that apply.A. diploidB. eggC. somaticD. gameteE. sper
Marrrta [24]

Answer:

A. diploid and C. somatic

Explanation:

Humans are diploid organisms and have 23 pair of chromosomes i.e. in total humans have 46 chromosomes.

There are 2 types of cells in humans (1) somatic cells and (2) germ cells.

Somatic cells are normal body cells which are diploid and have all 23 pairs of chromosomes. But, germ cells are special type of cells which are produced by gonads (sex organs). Germ cells are also known as gametes. In females, ovary is the sex organ which produces germ cells named as egg cells while in males testes is the sex organ which produces germ cells named as sperms. Germ cells (egg and sperm) are haploid cells which fuse to form a zygote which is the first cell of next generation. The process of fusion of egg and sperm is known as fertilization which is responsible for restoring diploidy in the progeny which receives half the genetic material from female parent and half the genetic material from male parent.
