In which layer of the atmosphere does the aurora borealis form? O A. The troposphere OB. The mesosphere O C. The thermosphere O D. The stratosphere SUBM
Answer:
The Thermosphere
Explanation:
Just took the test on A P E X, it's right. Hope this helps :)
Aurora Borealis forms in the thermosphere layer of the atmosphere. Therefore, option "C" is correct.
What are the different layers of the atmosphere?The atmosphere is made up of different layers which protect the life on Earth and make it habitable. There are four layers of the atmosphere troposphere, stratosphere, mesosphere, and thermosphere.
In the troposphere, the temperature rises from bottom to top. The ozone layer is present in the stratosphere. This is also known as the flying zone as no clouds are present in this layer. In the mesosphere, the air is much colder as there are gas molecules present that absorb solar radiation whereas the density of molecules in the thermosphere is very low.
The atmospheric layers protect the life on Earth.

Define “isotope” using mass number, atomic number, number of protons, neutrons and electrons. (PLEASE HURRY!)
Isotopes have different mass numbers due to different number of neutrons but same atomic number due to same number of electrons and protons.
What are isotopes?
Isotopes are defined as substances having same number of protons but different number of neutrons.Number of protons is characteristic for determining position of elements in the periodic table.
Since,all isotopes have the same number of protons and hence have same position.They have similar chemical properties as they have same number of electrons.
They find applications in the field of nuclear medicine and oil and gas research . There are 2 types of isotopes : stable and unstable
Unstable isotopes are radioactive and are called as radioisotopes.Some of these isotopes are man -made and hence also called as artificial isotopes.Every element has an isotope which is either man-made or natural .
Many properties of isotopes depend on mass which is measured in atomic mass unit. The difference in actual mass and mass number is called mass defect.

How are humans affected by population growth of other organisms in anarea?
Answer:
yes
Explanation:
other organisms include things such as plants, insects and animals which can play a large role in the population. For example, if you have a sudden rise in the population of misquitoes that can be really bad since they can spread diseases to people when they are sucking blood. Antoher example is if there is a sudden growth of animals that eats a certain crop, then farmers will stuggle to maintain their crops and the list goes on. Hope this helps :)

How do your interactions with nonliving systems affect your environment?
Answer:
Some examples of important nonliving things in an ecosystem are sunlight, temperature, water, air, wind, rocks, and soil. Living things grow, change, produce waste, reproduce, and die. These living things interact with the nonliving things around them such as sunlight, temperature, water, and soil.
Explanation:
Nonliving factors determine what living things can be supported in an ecosystem. The living creatures in a habitat affect the nonliving elements within the community. For example, plants can affect soil chemistry or certain algae can influence water chemistry.

Answer:
the heart is what makes every moving part working inside our body even though the brain is the one who tells them or gives them signals to work. the heart is what keeps them alive and if the heart takes any kind of negative damage the would not take care of everything it's supposed to.
Explanation:
Hope this helps
The body part picked is ; The Heart
An injury or disease to the heart will stop the whole body functioning and the process modeled will be distorted
The heart in the body is equivalent to the engine of a car, The heart pumps oxygen carrying blood cells into all the organs and without this oxygen carrying blood cells the whole body will stop functioning ( i.e. The organs will be dead ).
An injury or disease to the Heart will negatively affect the distribution rate of blood to all parts of the body and this will negatively affect the overall wellbeing of the body and this will also negatively affect the process been modeled as well.
Hence we can conclude that The body part picked is ; The Heart , and An injury or disease to the heart will stop the whole body functioning and the process modeled will be distorted
