Answer: option D) Cells can function equally as well at all pH's because enzymes are effective at all pH's.
Explanation:
Studies in biology have demonstrated that:
- All living tissues have different pH (stomach is acidic, it has a pH below 7; saliva is alkaline, it has pH above 7 etc)
- All living tissues has a stable physiological temperature of 37°c
- All living tissues contain enzymes such as Catalase
Thus, based on the information given, we can infer that all cells can function equally as well at all pH's (whether acidic, neutral or alkaline) because enzymes are also effective at all pH's.
The substance is guided through a protein embedded in the membrane from high to low concentration since this not considered as active.
(a) Aquatic ecosystems are rich in diversity. The life inside water is largely influenced by various abiotic factors. The abiotic factors are the chemical and physical components of an environment that affect the organisms living there. The primary abiotic factors that affect the life underwater are temperature, light and availability of oxygen.
(b) Oxygen available to the aquatic organisms is a detrimental factor. If less oxygen is available underwater aquatic animals will not be able to respire and die.
Light is also an important abiotic factor for underwater organisms especially for the aquatic plants. the aquatic plants underwater will not be able to make their food by photosynthesis if proper light is not available.
Temperature also plays an important role. Too low or too high temperature affects the metabolic activities of the organisms.
Depth of water body affects the availability of light and oxygen to the aquatic organisms. Shallow water bodies have light available to more aquatic organisms.

Answer:
<h2><u>systematic desensitization.</u></h2>
Explanation:
You are suffering from arachnophobia. Your therapist first has you go through relaxation training, then has you construct a fear hierarchy and, finally, has you go through a phase of graded pairings of spiders and relaxation responses. This approach is called <em><u>systematic desensitization.</u></em>
