Data samples in which you expect no change to occur are_____.

mina [271]

The answer is negative controls. These are groups where no phenomenon is probable. They ensure that there is no effect when there should be no effect. Where there are only two possible outcomes, e.g. positive or negative, if the treatment group and the negative control both produce a negative result, it can be concluded that the treatment had no effect. If the negative control group and the treatment group both yield a positive result, it can be inferred that a puzzling variable is involved in the occurrence under study, and the positive results are not only due to the treatment. In other examples, outcomes might be measured as lengths, times, percentages, and so forth.

Which is the MOST accurate description about how the different types of feed mechanisms work.

marishachu [46]

Answer:

Explanation:

Positive feedback loops are rarer than negative ones because of homeostasis, but they do occur. Negative feedback loops return to the set point in reverse, and positive feedback loops amplify a departure from the set point.

You get home from school and grab a bag of potato chips before settling onto the couch to binge watch your newest Netflix series

snow_tiger [21]

Answer:

Explanation:

Osmosis is the process in which the molecules of a solvent move from a region of low concentration to a region of higher concentration through a semi-permeable barrier.

While eating the chips, the salt content from the chips makes the surrounding solution of the cells to have an increase in salt concentration causing an hypertonic solution. An hypertonic solution is a solution that has more solute (salt) than the (solute in a) cell. This increase in salt concentration around the cells causes the cells to release water to neutralize the high salt concentration in the solution around the cell (in order to maintain homeostasis) which causes dehydration in the individual and hence making the individual to be thirsty. The body attempts to maintain balance by passing this excess salt out of the body in the form of urine hence the reason for the dark colour in the urine (because if the body doesn't rid itself of the high salt concentration, the cells could shrink and die as a result).
