Option (B).

Explanation:

Fundamentals of Emergency Management (FEMA) may be defined as the organization that helps in the management of resources. This also helps to deal with the all  humanitarian emergency.

Prevention activities to remove the particular danger are also listed in the FEMA.  The identification for the site access previously might helps to reduce the health related and risk related problems of the individuals working at the site.

Question 1 of 10
Sati [7]

Answer: Option A) Parathyroid glands

Explanation:

The Parathyroid gland located in the neck region helps in the secretion of an hormone called Parathormone.

This hormone helps to raise the levels of calcium ions in the body, by preventing the loss of calcium ions through urine, and also preventing excess deposit of calcium ions in the bone, thus regulating bone density.

A student performed an experiment with bags of dialysis tubing filled with distilled water to model the process of osmosis. Dial
Reil [10]

Answer:

Taking into account the principle of osmosis, the question that best addresses experimental design is  <em>How does the effect of environmental sucrose concentrations impact the  movement of water across a membrane?</em>

Explanation:

The experimental design of the student, made with dialysis bags and sucrose at different concentrations should recreate the principle of osmosis, of importance in living beings for organic homeostasis.

Osmosis consists of the movement of water - through a semi-permeable membrane - from a less concentrated solution to a higher concentration solution, following a gradient, to achieve balance.  

The student will observe in his experiment that water moves from the solution with less sucrose concentration to the higher concentration of sugar. Beakers with the highest concentration of sucrose will have the highest weight, due to the increase in liquid volume.

How does the effect of environmental sucrose concentrations impact the  movement of water across a membrane?

The experiment shows that:

  1. The water from the beaker with less sucrose concentration moved -through the dialysis tubes and the membrane- to the beaker containing the most concentrated sucrose.
  2. Different sucrose concentrations will attract different amounts of water, which influences the final weight of each container.

With this experiment the principle of osmosis is confirmed, where the concentration of a solute determines the amount of water that passes through a semipermeable membrane -following a concentration gradient- until equilibrium is reached.
