Complete Question:

Cortisol is a hormone produced in response to stress, including starvation, in humans. Which of the following is most likely an immediate effect of a starvation-induced increase in cortisol secretion?

(A) Increased activation of the immune system

(B) Increased urine production by the kidneys

(C) Increased bone and collagen formation

(D) Increased mobilization of fatty acids from fat cells

Answer: Increased mobilization of fatty acids from fat cells.

Explanation: Cortisol is a hormone produced in response to stress, including starvation, in humans. Immediate effect of a starvation-induced increase in cortisol secretion is the increased mobilization of fatty acids from fat cells (Adipose tissue).

Starvation occurs when an animal doesn't feed due to unavailability of food. The body system makes use of stored glycogen which is synthesized to glucose by hormonal secretion of glucagon by the pancreas.

However, when the glucose converted is finished. Cortisol is secreted, which then initiate the mobilization of fatty acids as source of energy from the adipose tissues (fat cells) in the body system.

After the worms have finished eating their food, the students must now weigh the worms and record this data. They can then compare these new weights to the starting weights of the worms and see if it demonstrates their hypothesis. Hope this helped :)

Is Solid waste point source pollution or non point source pollution?
Yanka [14]

Answer:

Nonpoint-source pollution is the opposite of point-source pollution, with pollutants released in a wide area. As an example, picture a city street during a thunderstorm. As rainwater flows over asphalt, it washes away drops of oil that leaked from car engines, particles of tire rubber, dog waste, and trash. The runoff goes into a storm sewer and ends up in a nearby river. Runoff is a major cause of nonpoint-source pollution. It is a big problem in cities because of all the hard surfaces, including streets and roofs. The amount of pollutants washed from a single city block might be small, but when you add up the miles and miles of pavement in a big city you get a big problem.

In rural areas, runoff can wash sediment from the roads in a logged-over forest tract. It can also carry acid from abandoned mines and flush pesticides and fertilizer from farm fields. All of this pollution is likely to wind up in streams, rivers, and lakes.

Airborne pollutants are major contributors to acid rain. It forms in the atmosphere when sulfur dioxide and nitrogen oxides combine with water. Because acid rain results from the long-range movement of those pollutants from many factories and power plants, it is considered nonpoint-source pollution.
