Answer:
Active transport requires cellular energy for substances to cross the cell membrane; passive transport does not.
Explanation:
Active Transport works against the concentration gradient and therefore needs energy to make it happen
Passive transport such as Diffusion and Osmosis uses the properties of natural movement of particles which moves the molecules from areas of high concentration to areas of low concentration or down the concentration gradient and happens passively without the need for energy
Archaebacteria move by using the form of a flagellum to propel a themselves.
hope that helps
Answer: option A - denature
Explanation:
Microbial control agents are KNOWN to DENATURE cell proteins as a step in pathology of many diseases.
And because PROTEINS ACTIVITY depends on their three dimensional configuration, microbe attack and BREAK the bond in order to penetrate the cell membrane.
So, the ONLY right option is A
I'm a little confused by this question. Hypertonic just means that something has more of something than another thing. For example, if you place a cell in a solution, and 2% of the cell is made out of something while the solution is made out of 40% of the same thing, the solution would be hypertonic to the cell. Sorry if that explanation doesn't make sense, I tried my best lol.
Although I'd assume the answer is passive transport as anything that is hypertonic to something else will diffuse down its gradient in an attempt to reach a balance.
Answer:
True
Explanation:
Hostility can be explained in clear terms as a form of emotion portrayed in an aggressive manner, which is unfriendly and an arousal of anger from within as a result of denial or rejection.
Coronary heart disease occurs when major blood vessels that supply blood,oxygen,and nutrients to the heat becomes damaged. It major cause are inflammation or cholesterol deposits in the arteries that supply all these nutrients, oxygen and blood to the heart. This causes coronary arteries to narrow, limiting blood flow to the heart. It is said that some slight modifications to care for coronary heart disease include a better lifestyle changes,socialization etc, but when an individual susceptible to coronary heart diseases is hostile, it endanger the effect of such individual more to chronic effects.
Hostility levels is also related as a better predictor of coronary heart disease risk than factors such as high cholesterol, high blood pressure etc. This is because more heart attacks are attributed to anger than high cholesterol.
