1. Explain the function of white blood cells in the body.
Wittaler [7]

Answer:1. White blood cells are part of the body's immune system. They help the body fight infection and other diseases.

2. Red blood cells have adaptations that make them suitable for this.

3. The blood would not clot in case of an injury.

4. Blood supplies essential substances and nutrients.

Explanation: 1. White blood cells are able to recognize viruses and/or infectious germs, which is how they fight off disease/sickness. It is also why we have vaccines. Vaccines put either dead or weakened parts of a germ into your body. Then, the white blood cells recognize it and fight it off the next time it enters your body.

2. They contain hemoglobin, a red protein that combines with oxygen. They have no nucleus so they can contain more of the hemoglobin. they are small and flexible so that they can fit through narrow blood vessels.

3. This will lead to excess blood loss and can even lead to the death.

4. Such as as sugar, oxygen, and hormones to our cells. It also carries waste away from the cells, this waste is eventually flushed out of the body in urine, feces, sweat, and lungs.

Cells can make proteins that need to be transported out of the cell and moved to another part of the body. Cells also make carbo
alex41 [277]

Answer:

The proteins will be transported through exocytosis; the carbon dioxide will diffuse through the membrane.

Explanation:

Diffusion is the passive transport of substances down their concentration gradient. The process moves the substances from the region of higher concentration to that of lower concentration. CO2 is a small molecule and does not have any charge. Small, uncharged molecules can diffuse through the lipid bilayer of the cell membrane. Therefore, CO2 can exit a cell by simple diffusion.

On the other hand, proteins are too large to be transported by diffusion across the cell membrane. The proteins are transported by exocytosis. During exocytosis of proteins, membrane-bound vesicles are formed inside the cell. These vesicles carry proteins in them and are called secretory vesicles. The membrane of the vesicles fuse with the cell membrane of cells and transport the proteins outside the cell.
