What is the difference between metaphase in mitosis and metaphase II in meiosis? How are they the same?
lora16 [44]

Answer:

What is the difference between Metaphase 1 and Metaphase 2? In Metaphase I, the 'pairs of chromosomes' are arranged on the Metaphase plate while, in the Metaphase II, the 'chromosomes' are arranged on the metaphase plate. In Metaphase I, the spindle fibers get attached to two centromeres of each homologous chromosome.

In metaphase 1 the pairs of chromosomes referred to as bivalents are totally condensed. Moreover the in metaphase 1 of meiosis there is no centromere division whereas in metaphase of mitosis it does. They align on the metaphase plate in between the poles.

Answers:

1. Facilitated diffusion: the process by which some molecules that are not able to pass directly through a cell membrane are able to enter the cell with the aid of transport proteins.

2. Osmosis: the diffusion of water molecules through a selectively permeable membrane.

3. Diffusion: the spreading out of molecules across a cell membrane until to they are equally concentrated.

Step-by-step explanation:

Diffusion is the spontaneous movement of molecules across a membrane from an area of high concentration to one of low concentration gradient.

Osmosis is the diffusion of water molecules across a semipermeable membrane from an area of low solute concentration to one of high solute concentration.

Facilitated transport occurs when molecules cannot diffuse directly through a cell membrane but can diffuse down a concentration gradient through transport channels in the membrane.
