Answer 1

1) True. 2) False. 3) False. 4) True. 5) True. 6) True. 7) True. 8) False.

Step-by-step explanation:

1) True

Osmosis is indeed the passive movement of water, but it does follow the same general principles of diffusion. Both osmosis and diffusion involve the movement of substances from an area of higher concentration to an area of lower concentration. The main difference is that osmosis specifically refers to the movement of water across a selectively permeable membrane.

2) False

The correct order of phases in mitosis is: Prophase, Metaphase, Anaphase, and Telophase. In Prophase, the chromosomes condense and the nuclear envelope breaks down. In Metaphase, the chromosomes line up along the metaphase plate. In Anaphase, the sister chromatids separate and move to opposite poles. In Telophase, the chromosomes decondense and the nuclear envelope reforms.

3) False

DNA transcription and DNA replication are two different processes. DNA replication is the process by which a cell makes an identical copy of its DNA, while DNA transcription is the process by which a segment of DNA is used as a template to produce a complementary RNA molecule.

4) True

The glycocalyx is indeed composed of glycolipids, glycoproteins, and cholesterol molecules displayed on the outside surface of the plasma membrane. It plays an important role in cell recognition and communication.

5) True

Interstitial fluid is indeed one type of extracellular material. It surrounds and bathes the cells in tissues and plays a role in delivering nutrients and removing waste products.

6) True

The speed of individual particle diffusion is influenced by temperature and particle size. Higher temperatures increase the kinetic energy of particles and speed up their movement, while larger particles diffuse more slowly than smaller particles.

7) True

Concentration differences do indeed play a role in causing ionic imbalances and polarizing the cell membrane. Active transport processes, such as the sodium-potassium pump, use ATP to actively transport ions against their concentration gradients, contributing to the polarization of the cell membrane.

8) False

A red blood cell placed in pure water would actually swell and become swollen, but it would not burst. This swelling occurs because water would enter the cell via osmosis, moving from an area of lower solute concentration (the pure water) to an area of higher solute concentration (inside the red blood cell).
