Answer:
Active transport requires energy from ATP while facilitated diffusion does not
Explanation:
Active transport and facilitated diffusion with the use of channel and carrier proteins are both ways by which ions, polar and large molecules cross a selectively permeable membrane.
The major difference is that; Active transport transport these particles from a low to high concentration, which is against concentration gradient and hence, energy is required to perform the task
Facilitated diffusion transport from a high to low concentration, which is through a concentration gradient and hence, no energy is required to perform the task.
For mutations to affect an organism's descendants, they must: 1) occur in cells that produce the next generation, and 2) affect the hereditary material. Ultimately, the interplay between inherited mutations and environmental pressures generates diversity among species.
Answer:
a-translocation
b- digestion
c- egestion
d- nutrition
e- absorption and assimilation
Each (both large and small) colony is carefully counted (using magnifying colony counter if needed). Each colony represents a “colony-forming unit” (CFU). For accurate counts, the optimum count should be within the range of 30-300 colonies/plate. To insure a countable plate a series of dilutions should be plated.
The correct answer is D. The flavor of carrots grown under different conditions is compared.
Qualitative observation is the observation which deals with describing the quality of a thing by observing its properties with our senses, without discussing the numerical values. Examples of qualitative observations are observing colors, texture, and shape, size flavor of a thing. Therefore, the comparison of flavor of carrots grown under different conditions is a qualitative observation.
