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.

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.

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.

Explanation:

Manipulated variable: The manipulated variable in this experiment is the type of substance (water or dry sand) being heated under the lamp.

Responding variable: The responding variable is the temperature of the substance, as it changes over time in response to the heat source.

The scientist manipulated the type of substance (water or sand) and observed how the temperature of each substance responded to the heat source, identifying the manipulated and responding variables.

Which description of tectonic plates are true?


A) number in the hundreds

B) move very slowly

C) move over the layer of Earth's mantle

D) can crush together to create mountains

Answers

I believe the answer would be D because when they collide they move the Earth
It would either be B: because they do move really slowly or D: because they can create mountains when they crush together. But creating mountains, in my opinion, is not a description. It's something that can occur, but it's not describing tectonic plates. So I would go with B.

Select the forms or examples of solar energy:

heat energy
solar oven
rock sediments
petroleum
coal
light energy

there is more than one answer

Answers

Final answer:

The examples of solar energy are heat energy, solar oven, and light energy. Heat energy from the sun is directly used or converted into electricity by solar panels.

Explanation:

The forms or examples of solar energy from the provided list are heat energy, solar oven, and light energy. Solar energy, which includes both heat and light, can be used directly to produce thermal energy or can be converted into electricity using technologies like photovoltaic (PV) panels or solar thermal power plants. A solar oven is a device that harnesses solar energy to cook food or boil water, utilizing the heat generated by the sun's rays.

An example of heat energy being converted into another form of energy not mentioned in the text is in the case of solar panels, which convert the thermal energy from the sun into electrical energy.

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.

Krypton is non metal it is part of the noble gas family.  It has 36 protons and 48 neutrons. Its symbol is Kr. Krypton, like the other noble gases, is used in lighting and photography. Krypton was discovered in Britain in 1898 by Sir William Ramsay, a Scottish chemist, and Morris Travers, an English chemist, in residue left from evaporating nearly all components of liquid air. Neon was discovered by a similar procedure by the same workers just a few weeks later.
