When blood supplies oxygen and food to a cell surface and these molecules diffuse across, we might expect some "resting time." However, if we inspected most cell membranes in a living human body, we would find a nearly continuous flow of substances back-and-forth across the plasma membrane. Which of the following is not a reason why? a) Cell metabolism is constantly using up oxygen and raw materials; this lowers their concentration so more will diffuse into the cell. b) Cell metabolism is constantly producing waste molecules; this increases their concentration so more will diffuse out of the cell. c) Cells produce useful secretions; this increases their concentration and more will diffuse out of the cell. d) Cell metabolism constantly produces carbon dioxide in respiration; this increases its concentration so more will diffuse out of the cell. e) Cells are living entities and in order to live can never "rest".

What changes can occur in an aquatic ecosystem as a result of nutrient loading?

Answers

Yes, definitely algal bloom is a significant change. What is more important is how the bloom affects other aquatic life. The bloom forms a dense "blanket" of growth, which as it grows rapidly and dies, decomposes. Bacteria feed on this rich organic stuff and use up the dissolved oxygen in the water. As the oxygen levels drop, fish and aquatic insects die. This is the result of the algal bloom.

Why stirring the water in an experiment will make results more reliable?

Answers

You will have a more even spread of heat in your solution aka evenly dispersed kinetic energy
only if you stir it for each repeat/measurment, and keep the amount/viguor with which you stir at the same level for each repeat.

What is a nonnative animal that moves into a new place?

Answers

Answer:

Invasive species

Explanation:

Any organism that enters a habitat where it does not belong is an invasive species. There are many plants that have been brought from other countries, and sometimes they take root in the new habitat.

The same thing with animals and migration patterns, if a species moves to a new habitat it is known as an invasive species.

The danger with this phenomenon is that sometimes the invasive species will compete with the natural occuring wildlife.
Nonnative species that move to  a new habitat are called invasive species.

The way a glacier moves depends on the relationship between _____ and wastage.drift
accumulation
plucking
grinding

Answers

The correct answer is accumulation.


The way a glacier moves determines on the relationship which is between the accumulation and wastage.


Glacier is termed as a persistent body dense ice which is constantly moving under its own weight.

It is formed where accumulation of snow exceeds its ablation or sublimation and melting.

Glacier flow and deform because of stressed and also distinguish features.

99% of glacier on earth is contained in the vast ice sheets in polar regions. Glacier can be found on mountain ranges.
Accumulation
The movement of a glacier depends on the ablation, or wastage, and the accumulation.
