Question:
Study the illustration. The small blue spheres represent water molecules.

In which direction will water molecules move across the membrane?


Water will move from A to B.


Water will move from B to A.


There will be no net movement of water.

Answers

Answer 1

Given the illustration shown in the image attached to this answer, water molecules will move from B to A.

Osmosis is defined as the movement of water molecules across a semi - permeable membrane from a region of higher concentration to a region of lower concentration. Osmosis usually occurs across the cell membrane.

The cell membrane is an example of a semi - permeable membrane. Hence, water moves from B where it is at a higher concentration to A where it is at a lower concentration according to the definition of osmosis.

Answer:

Atomic Models Of Elements: Atoms consist of three basic particles: protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). ... Atoms are made up of protons and neutrons located within the nucleus, with electrons in orbitals surrounding the nucleus.

Lithium:Lithium is a chemical element with the symbol Li and atomic number 3. It is a soft, silvery-white alkali metal. Under standard conditions, it is the lightest metal and the lightest solid element. because it is present in trace amounts in virtually all rocks.

Florine:Fluorine is a chemical element with the symbol F and atomic number 9. It is the lightest halogen and exists at standard conditions as a highly toxic, pale yellow diatomic gas. As the most electronegative element, it is extremely reactive, as it reacts with all other elements, except for argon, neon, and helium.

Electron:Electron is a free and open-source software framework developed and maintained by GitHub. It allows for the development of desktop GUI applications using web technologies: it combines the Chromium rendering engine and the Node.js runtime.

Neutron:The neutron is a subatomic particle, symbol n or n⁰ , which has a neutral charge, and a mass slightly greater than that of a proton. Protons and neutrons constitute the nuclei of atoms.

Proton:A proton is a subatomic particle, symbol p or p⁺ , with a positive electric charge of +1e elementary charge and a mass slightly less than that of a neutron. Protons and neutrons, each with masses of approximately one atomic mass unit, are jointly referred to as "nucleons".

Why is plastic a non-biodegradable and nonpoint source of pollution?

Answers

Plastic is a non-biodegradable and non-point source of pollution because it cannot be broken down into degradable materials by micro-organisms. It comes from man-made substances and industries therefore, it is non-point pollutant.

What is Plastic?

Plastic is a non-biodegradable and non-point pollutant. Because, the enzymes in the microorganisms cannot break down the waste into bio-degradable materials as microbes cannot recognize the bonds that hold these polymers together. Eventually, the polymers in plastic may break down, perhaps after hundreds of years. But after a long time, the damage is already done to the environment.

Nonpoint source of pollution comes from oil, pet waste, herbicide, bacteria, sediment, and any other contaminant that ends up on the ground naturally or from human activity.

How would the equilibrium change if the ocean became more acidic?

Answers

Answer: more H2CO3 is made

Explanation:

Acidic water of the ocean creates instability in the ocean ecosystem.

What happens when ocean become acidic?

If the acidity of ocean increases the corals can't build skeletons and the shellfish also can't build the shells which they need for protection.

Corals are particularly important because they provide homes for many other sea creatures so we can conclude that acidic water of the ocean creates instability in the ocean ecosystem.

What is the connection between the liquid state of water and hydrogen bonding?

Answers

Answer:

Explanation:

Answer:

d) less dense

Explanation:

When fluids (liquids and gases) are heated, they expand and therefore become less dense. Any object or substance that is less dense than a fluid will float in that fluid, so hot water rises (floats) in colder water.
