Answer:

The degree in which materials are able to flow freely through a cell's membrane known as permeability.

Explanation:

The permeability of membrane is the rate of passive transport through the membrane. These molecules are known as permeant molecules.The permeability of a cell membrane are dependent on certain factors such as polarity, electric charge and molar mass of the molecules which diffuse through the cell membrane. Phenylalanine increases the permeability of membrane. When there is an increase in the temperature it also increases the permeability of membrane. When there is a water in the cells it will result in water expansion, there will be exertion of pressure on membrane and deformation of the transport proteins so that they will able to control what will enter or leave the cell. Selective permeability of the membrane plays a very significant role in maintaining homeostasis, fluid & electrolyte balance & cellular health.

27. A form of energy is stored in the bonds

lubasha [3.4K]

A form of energy that is stored in the bonds between atoms of a chemical element is referred to as: B. chemical energy.

A chemical energy can be defined as a form of energy that is stored within the forces of attraction (bonds) that are existing between ions, crystals, atoms or molecules.

In Chemistry, bond energy refers to the amount of chemical energy that is required to break one (1) mole of a particular chemical bond. Also, bond energy is measured in kJ/mol.

In conclusion, a form of energy that is stored in the bonds between atoms of a chemical element typically is referred to as chemical energy.

How do you think this transfer of electrons helps the lactic acid fermentation process repeat itself?

Lisa [10]

Answer:

By changing pyruvate into lactic acid with this transfer of electrons.

Explanation:

Transfer of electrons helps the lactic acid fermentation process repeat itself because the pyruvate molecule takes electron from NADH which is reduced to lactic acid so indirectly with the transfer of electrons helps the lactic acid fermentation process to repeat itself. If these electrons are not transferred from NADH to pyruvate molecules so the lactic acid is not formed.

ladessa [460]

The following equipments would be needed to bring one liter of water to 85°C: graduated cylinder, beaker, thermometer and hot plate.

SCIENTIFIC EQUIPMENT:

Scientific equipments are required to make scientific works conducted in the laboratory achievable. Different scientific equipments perform varying functions and they collectively help to achieve tasks.

The following are scientific equipments that would be used to bring one liter of water to 85°C:

Graduated cylinder: The graduated cylinder is a calibrated cylindrical flask used to measure the volume of a liquid substance. The graduated cylinder would be used to measure one liter of water.

Beaker: The beaker is a flask used to hold liquid substances and reagents. The beaker would be used to hold 1L of water.

Hot plate: Hotplate is an equipment that is used to boil the water to the desired temperature.

Thermometer: Thermometer is a device used for measuring the temperature of a substance. The thermometer would be used to measure the temperature of water to 85°C.

Hence, the following equipments would be needed to bring one liter of water to 85°C: graduated cylinder, beaker, thermometer and hot plate.
