What process involves substances scatter themselves evenly throughout an available space?

What process involves substances scatter themselves evenly throughout an available space?

A principle of diffusion is that the molecules move around and will spread evenly throughout the medium if they can.

What is it called when substances scatter around a space?

Diffusion. substances scatter themselves evenly throughout an available space. no energy required. movement is from high to low concentration. two specialized types of diffusion: osmosis, dialysis.

Which process does not rely on active transport quizlet?

Channel-mediated diffusion is a form of passive, not active, transport. Any type of diffusion results from substances moving down their concentration gradient, a form of kinetic energy. In order to move, or actively pump, substances against their concentration gradient, energy must be used.

Which organelles can be called the digestive bags of the cell *?

Lysosomes are the cell organelle present in the eukaryotic cells. They are membrane-bound organelle found in many animal cells. They are small, spherical-shaped vesicles inside which the hydrolytic enzymes are found that can break down various types of biomolecules.

Which two types of tissues have the greatest ability to repair themselves?

Epithelial and connective tissues have the greatest capacity to regenerate. In small wounds and injuries, the epithelial and connective tissues often heal with normal tissue. The ability of muscle tissue to regenerate is very limited. Fibrous connective tissue often replaces damaged muscle tissue.

What is meant by selectively permeable?

Selective permeability of the cell membrane refers to its ability to differentiate between different types of molecules, only allowing some molecules through while blocking others. Some of this selective property stems from the intrinsic diffusion rates for different molecules across a membrane.

What type of transport does not require any energy?

Simple diffusion
Simple diffusion does not require energy: facilitated diffusion requires a source of ATP. Simple diffusion can only move material in the direction of a concentration gradient; facilitated diffusion moves materials with and against a concentration gradient.

How do large amounts of water pass through the membrane?

Large quantities of water molecules constantly move across cell membranes by simple diffusion, often facilitated by movement through membrane proteins, including aquaporins.

Which of the following assists the movement of substances like glucose facilitated diffusion?

What assists the movement of substances by facilitated diffusion? protein carrie or channel.

What can be found in all eukaryotic cells?

Eukaryotic cells are very diverse in shape, form and function. Some internal and external features, however, are common to all. These include a plasma (cell) membrane, a nucleus, mitochondria, internal membrane bound organelles and a cytoskeleton.

What’s the center of a cell?

Nucleus. The nucleus serves as the cell’s command center, sending directions to the cell to grow, mature, divide, or die. It also houses DNA (deoxyribonucleic acid), the cell’s hereditary material.

Are often referred to as the power plants of a cell?

Mitochondria are the power plants of the cells. They transform energy taken up through nourishment into a form the cells can use for a multitude of necessary metabolic reactions. In addition, mitochondria are responsible for triggering programmed cell death.
