The correct answer is option D, that is, ice floating on the water surface.

The cohesive forces among the molecules of a liquid are accountable for the process called surface tension. Surface tension refers to the tension of the surface film of a liquid resulting due to the attraction of the particles in the surface layer by the bulk of the liquid that seems to reduce the surface area.

The examples of surface tension are walking of small insects on water, floating of a needle, the surface tension of water offers the essential wall tension for the creation of bubbles with water, and surface tension is accountable for the shape of liquid droplets.

The low density of ice makes it float at the liquid water surface, like ice cubes in a glass of water, or an iceberg. The lower density of water in its solid form is because of the way hydrogen bonds are aligned as it freezes, the water molecules are pushed further far away in comparison to the liquid water.

Answer:

B)protons, down

Explanation:

Chemiosmosis is the diffusion of ions through a selective permeable membrane. It specifically refers to the production of ATP through the movement of hydrogen ions through an inner membrane during cellular respiration. Hydrogen ions diffuse from an area of high proton concentration to one of lower concentration.

Amphibians moved to a terrestrial environment; however, they did not evolve the ability to live their entire lives on land. Expl

Gekata [30.6K]

Answer:

See the answer below

Explanation:

Amphibians are not totally adapted to live on land because the aquatic environment is needed for several life processes such as reproduction, respiration, and sometimes, feeding.

The eggs of amphibians are without any protective shells and will suffer desiccation in the terrestrial environment. Hence, water is needed in order to protect the eggs. In addition, the male amphibians shed their sperm in the water close to the female eggs.

The young ones of amphibians are essentially aquatic and may not survive out of water for a long time because they only breathe gills - the lung is yet to develop or poorly developed at this stage. They have to grow and develop to a certain stage in water before they can start surviving on land.
