Answer:

Steroids are also lipids but they have a carbon skeleton of four connected rings (no glycerol here) (3.9, pg 41). The different properties of different steroids are due to the attached functional groups. Cholesterol is a steroid that can be modified to form many hormones.

Setler79 [48]

Sulfur emissions from industry combine with water in the atmosphere and form acid rain. A new factory is built very close to the lake that Josh visits often. By examining the table that shows what pH range different species can survive, Josh decides that the aquatic life will be affected by the changes in pH that the lake. Josh correctly decides that organisms that will be the most affected are

A) perch and frogs.

B) mayfly and bass.

C) snails and clams.

D) frogs and salamanders.

The correct answer is option (C) snails and clams.

Acid rain is formed when oxides of sulfur and nitrogen combine with water molecules. Industries are one of the major contributors to acid rain. pH is a measure of acidity or alkalinity in water.

A factory built close to the lake can cause acid rain which affects the pH of the lake. Any change in the pH of the lake has an effect on the organisms in it. A pH of 7 is considered to be neutral and pH values below 7 indicates acidity and pH values above 7 indicates alkalinity. Organisms have an acid tolerance level beyond which they are affected and can die. Perch has an acid tolerance of up to pH 4.5 and frogs can tolerate an acidic pH of 4.0. The acid tolerance level of Mayfly and Bass is a pH of 5.5. Salamanders can tolerate an acidic pH of 5. Whereas, Snails and Clams have a very less pH tolerance of 6. They are highly susceptible to acidic pH.

Thus, Josh correctly decides that organisms that will be the most affected are snails and clams.

Given Proposition: The Shark Population has increased. This is assuming that we only base it off of the given food tree, rather than using the food web, which is more factually correct. This means that the sharks in the area can only eat sea otters, and that sea star populations and sea otters can only eat clams.

1) In this case, the shark population increases. This generally means that the sea otter population by itself has increased, suggesting a positive net change within the given food chain. However, with increased shark populations, would mean a damage to the amount of sea otters in the area. This can create an underpopulation of sea otters, which, if sea stars were not a factor, can mean a increase of clam population.

However.

2) Sea stars are a part of the food chain given. Therefore, it can be suggested that while the sea otter population may stabilize and/or diminish, the sea star has no "predator". This means that with the decrease of the sea otter population, the sea star population may actually grow, as the competition for the same source diminishes. Again, with the demand taking over the need, the sea star population may fall once again due to overfeeding, and essentially starvation.

In essence:

Shark Population: Increased

Sea Otter Population: Decreases (is eaten)

Therefore, Clam Population is speculated to increase.

However, the Sea star population would thereby increase due to having more food.

A larger sea star population in which the clam population cannot sustain would collapse, leading to a fall.

Also, due to the smaller amounts of sea otters in the area, the shark population may also see to an decrease of population, as they die from starvation.

The sea otter population would then stabilize when the predatory amounts or less, and their competition collapses.

Of course, there will always be a "food web". Sea otters do not solely rely on clams, neither do sharks solely rely on otters.

andre [41]

Answer:

Parasympathetic nervous system

Explanation:

Parasympathetic nervous system (PNS) along with sympathetic nervous system (SNS) makes autonomic nervous system (ANS). ANS controls the functioning of internal processes like digestion rate, heart rate, respiratory rate etc. During a threat or stressful situation SNS is activated. It increases heart rate, respiratory rate and directs blood flow towards peripheral muscles as a part of "fight or flight response". When the situation becomes normal, PNS is activated which restores all the vitals as a part of "rest and digest" mechanism.

Since here Byron almost got into an accident, he was scared a lot due to which his SNS was activated. Eventually when he realized that he is out of danger, his PNS got activated which returned his heart rate and blood pressure to normal levels.
