The Aleutian Trench is an area where the oceanic Pacific Plate is converging with the continental North American Plate. What can you conclude is happening in this area?

Answers

Final answer:

In the Aleutian Trench, subduction of the Pacific Plate beneath the North American Plate causes frequent earthquakes and volcanic activity, and is part of the seismically active Ring of Fire.

Explanation:

The Aleutian Trench is a region where the oceanic Pacific Plate is converging with the continental North American Plate. In this area, a process called subduction is occurring, where the denser oceanic plate is sliding beneath the less dense continental plate. This subduction leads to frequent earthquake and volcanic activity due to the melting of the subducted plate that forms magma, which can then rise to the surface to create volcanic cones. Additionally, the subduction zone in the Aleutian Trench area is part of a larger zone known as the Ring of Fire, characterized by high seismic activity and numerous volcanoes encircling the Pacific Ocean.

Which do animal cells need in order to maintain homeostasis

A: light energy
B: carbon dioxide
C: chemical energy
D: carbon monoxide

Answers

some are behavioural changes
panting
shade seeking behaviour- to reduce radiation exposure
migration- to move to more suitable climates
curling up- reduce surface area to volume ratio

others include structual changes (you can not change this)

large size- for low surface to volume ratio
round shape/short extensions- low surface to area volume ratio

then you have physiological changes this is done by either the hormone (endocrine) system or nervous system

vasioconstriction- reduce blood flow to extemeties
shivering- increase metabolic heat produced


as you can see these adaptions are used to create a negative feedback.What this means is it is the oposite to the stimulas. For example if you get cold(stimulas) you may shiver which creates heat and warms your body( the opposite effect of being cold and thus the reverse to the stimulas)

note there is some that create positive feedback as well.

What can happen when you have taken much more than the normal amounts of vitamins?

Answers

Your body can either ignore the nutrients or reject them.

You can get sick from certain vitamins because your body wont be able to digest all of them, causing negative affects on your organs.

You can also just have nothing negative happen. For example, taking an extremely high dose of vitamin D3 would most likely not hurt you, however after a certain point you would not gain anything from it.

Answer:

Taking vitamins is a daily routine that has millions of people around the world. However, taking too many vitamins can lead to an overdose and be dangerous to health.

Explanation:

For example, water-soluble vitamins (vitamin B1, B2, B3, etc.) are excreted from the body and are not stored in the tissues. However, an overdose of some of these vitamins can induce side effects, such as irreversible nerve damage, or liver damage.

Meanwhile, fat-soluble vitamins (vitamin A, D, K, etc.) do not dissolve in water and can be stored in your body's tissues. Due to the accumulation of these vitamins, they are likely to produce toxicity or harmful effects much more than water-soluble vitamins.

What three factors led to the overthrow of the Chaldean empire? Explain.

Answers

One of the factors that lead to the downfall of the Chaldean empire was the Persian invasion. Although Belshazzar tried to fend off the Persian army, it was too massive to hold off. Another factor would be that Belshazzar was also betrayed by Gobryas, which lead the forces against the Persian army even at  greater advantage. Other than the governor, there were also other parties in the state that were also against the Chaldean kingdom. Lastly, there were also the foreign Jew exiles whom Cyrus the Great allowed autonomy and freedom to go back to their homes. From there, it was Cyrus the Great who brought the fall of the Chaldean empire.
