The red blood cells would look just fine or normal in the person who has drowned. Water wouldn't be lost because it wouldn't be attracted to the concentration of the salt water and the salt water would be too large to break the barriers.

Answer:

I would expect to see a withered cell because of the extreme lack of water.

Explanation:

Osmosis is the passage of solvent from a less concentrated solution to a more concentrated solution through a semipermeable membrane until the pressure exerted by the solution on the membrane prevents the passage of solvent. This process aims to balance the concentration of the solution.

Based on this, we can imagine what happens to the cells of a person who drowned in salt water.

Salt water has a higher salt (solute) concentration than human cells, so through osmosis the human cell provided a water outlet (solvent) to dilute the salt of the salt water and establish a balance between the medium. cell phone and salty water. With this extreme loss of water, human cells become wilted and collapse.

Cell walls are impermeable to transport of most materials required for bacterial nutrition.
mezya [45]

The given statement is False.

The bacterial cells walls are composed of peptidoglycan, also known as murein. It comprises polysaccharide chains cross-linked by unusual peptides, involving D-amino acids. The bacterial cell walls are distinct from cell walls of fungi and plants that are made up of chitin and cellulose, respectively.

The cell walls in bacteria allow small molecules to pass through them freely, however, do not permit large molecules to pass through them, in this manner, it function as a coarse filter.

The main function of the cells wall is to sustain the shape of the cell and inhibit the cell from bursting due to osmotic pressure. The cell wall allows the components to pass, which are essential for bacterial nutrition.

solniwko [45]

Answer:

Experiments

Explanation:

The ancient Greek philosophers spent more time philosophising and thinking about scientific explanations to phenomena in the natural world.

How ever, they relied solely on reasoning while attempting to explain scientific observations. Contemporarily, science is highly empirical. The scientific process can only be complete when scientific observations are subjects to rigorous experiments in order go determine the actual relationship between variables and provide better explanation for scientific observations.

Hence the ancient Greek philosophers should have used experiments rather than sole reason in proffering scientific explanations to natural phenomena.

Sav [38]

Answer: 1. The resting membrane potential would become less negative (more positive).

Explanation:

Resting membrane potential is a voltage carried by a resting (non-signaling) neuron, or called as resting potential, across its membrane.  The resting potential is determined by ion concentration gradients across the membrane, and the permeability of the membrane to each ion form.  

In a resting brain, there are gradients of concentration across the Na+ and K+ membranes. Forces shift their gradients down through channels, resulting in a separation of charges that provides the potential for rest. The membrane is much more permeable to K+ than to Na+, so the resting potential is similar to K+'s potential for equilibrium.

Hence, the correct option is 1. The resting membrane potential would become less negative (more positive).
