THE STRUCTURE OF THE CELL MEMBRANE
the cell membrane is a thin layer of a partially permable membrane. That protects the cell's organelles and helps to maintain the shape of the cell.
WHAT MATERIALS ENTER OR LEAVE THE CELL MEMBRANE.
since the cell membrane is partially permable, that it only allows some materials to pass through it only nutrients that need to be metabolized or neede by the cell is allowed or permitted to go in the cell either by diffusion or osmosis.
HOW IE ONE METHOD DIFFRENT FROM THE OTHER?
since diffrent materials that go in the cell have different concentrations, sizes, and weights, the method by which they go into the cell will definately be diffrent materials with larger molecules use the osmosis method to go in the cell, while materials with smaller molecules use the diffusion method. I HOPE THIS REALLY HELPED
Please state the following :)
Answer:
A. Integumentary system
Explanation:
The integumentary system consists of the skin,hair and nail. This system consists of the largest organ in the body. The skin helps in protection against pathogens by shielding the internal body system from external objects.
The skin also helps in Vitamin D production through sunlight.
It also helps to prevent dehydration through regulation of water loss.
The answer is C: because growth at 37°C would be ideal for revealing bacteria that are human pathogens. 37°C is equivalent to 98.6°F, the normal body temperature for humans. If bacteria are reproducing at this temperature in a petri dish, they are also most likely reproducing in the body.
Cultures are made so doctors can be sure a person is sick with a specific bacteria often in order to make sure they are taking the right medication to get better. Choice A doesn't make sense, because we wouldn't want to kill the bacteria we are trying to study. Bacteria that makes us sick is harmful bacteria and is what we are trying to isolate. Choice B doesn't make sense, because they are only being incubated at one temperature, not a range or variety. Choice D is harder to rule out, but again the doctor wants the bacteria to reproduce so they can be sure that's what is causing the infection, so it wouldn't make sense that we would put the bacteria in a temperature they would not reproduce.
Answer:
The bonds that will break at high temperature are hydrogen, ionic and Van der Waal's interactions. Covalent bonds will not break.
