Which describes simple diffusion
Nataly_w [17]

Answer:

Explanation:

Have you been through airport security lately? If you have, you’ve probably noticed that it’s carefully designed to let some things in (such as passengers with tickets) and to keep others out (such as weapons, explosives, and bottled water).

In many ways, airport security is a lot like the plasma membrane of a cell. Cell membranes are selectively permeable, regulating which substances can pass through, as well as how much of each substance can enter or exit at a given time. Selective permeability is essential to cells’ ability to obtain nutrients, eliminate wastes, and maintain a stable interior environment different than that of the surroundings (maintain homeostasis).

In the process of diffusion, a substance tends to move from an area of high concentration to an area of low concentration until its concentration becomes equal throughout a space. For example, think about someone opening a bottle of cleaning ammonia in the middle of a room. The ammonia molecules will initially be most concentrated right where the person opened the bottle, with few or no molecules at the edges of the room. Gradually, the ammonia molecules will diffuse, or spread, away from the place where they were released, and eventually you’ll be able to smell ammonia at the edges of the room. Ultimately, if the bottle is capped and the room is closed, the ammonia molecules will become evenly distributed throughout its volume.

Protected areas are an extremely important part of programs to conserve biodiversity and ecosystems, especially for sensitive ha

.    Copy and complete the sentences using these words ( some may be used twice)
sladkih [1.3K]

1. The right side of the mammalian heart pumps blood to the LUNGS.   Here it absorbs OXYGEN and is now called OXYGENATED blood.

The gas, CARBON DIOXIDE is removed from the blood in the lungs. The blood returns to the LEFT side of the heart and from here it is pumped to the BODY TISSUES where it gives up its OXYGEN and is now called DEOXYGENATED blood. It passes back to the LEFT side of the heart in VEINS    

2. Single Circulation -> The blood only passes through the heart once

   Double Circulation -> The blood  passes through the heart twice

3. Made of myocardium (thick muscle), four-chambered separated by valves, cardiac muscle is oxygenated via cornary ateries + veins, transports blood carrying oxygen + nutrients to the body's tissues
