Which best explains how the body maintains homeostasis?
kolezko [41]

McBossatronio,

The answer is the first option "all systems work together to stabilize the body." Homeostasis is the internal conditions that all living things have basically meaning how the body keeps cool during hot weather, or warm during cold weather.  You ever wonder why you sweat when it's hot, or shiver when it's cold that's your body keeping warm and cool which helps all your systems work together.

Hope this helps!

The approximate water temperature at a depth of 125 meters would be closest to: (1) 15°C (2) 8°C (3) 13°C (4) 3°C
photoshop1234 [79]

Answer:

(2) 8 ºC

Explanation:

The range of the temperatures from the uppermost layers of the ocean - around 100 to 150 m -, which in this case is 125 m, is not always constant as they fluctuate due to the atmospheric heating and cooling, and also due to seasonal variations.

However, if we base our answer on the table below, we would determinate that the approximate water temperature at a depth of 125 meters is 8 ºC (2). This is because, if we observe, the temperature at 100 m is 12 ºC, while at 150 m is 5 ºC. Therefore, the temperature at 125 m should be higher than 5 ºC and lower than 12 ºC, that is 8 ºC.

Mutations in ubiquitin lead to malfunction of what organelle in ALS that leads to buildup of mis-folded proteins?
sergiy2304 [10]

Answer:

Mitochondria.

Explanation:

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder in which the neuron died due to mutation in superoxide dismutase 1 gene. This disease is also known as Lou Gehrig's disease.

Mitochondria structure is disorganized in ALS. The ubiquitin protein mutation leads to the malfunctioning of mitochondria and misfolded proteins are made in the mitochondria.

Thus, the correct answer is option (a).
