Explanation:
The rescue workers can get energy to the batteries in their equipment during rescue missions by using a generator to convert the kinetic energy to potential energy. ... The best way is to use a hand crank such as a hand cranked flashlight or radio because it is easy to power enough energy for a short amount of time.

Explanation:
Consider the parts of a polar ecosystem and a desert ecosystem.
– Identify one abiotic factor present in each type of ecosystem.
– Identify one biotic factor present in each type of ecosystem.
– Explain why both the abiotic and biotic factors are different in each ecosystem. Use examples from each ecosystem in your explanation.
(NO LINKS PLEASE) (77 POINTS)
Answer:
One biotic factor includes soil, air(oxygen and carbon dioxide), water.
One biotic factor includes animals and plants.
Both factors are different in each ecosystem. This is because, for example, the soil in desert ecosystem can differ from the polar ecosystem. Animals in polar ecosystems include polar bears, wolves, etc. while desert ecosystems have animals like deer, artic fox, etc.

Use the diagram below to help you answer the following questions.
*Note that in the images below changes in eccentricity are exaggerated so the effect can be seen in the images. Earth's orbit shape varies between 0.0034 (almost a perfect circle) to 0.058 (slightly elliptical).*
a. A change in the eccentricity of Earth's orbit towards its maximum will increase or decrease the solar input that the Earth receives?
b. Explain how an increase in the eccentricity of the Earth’s orbit will alter the climate.
Answer:
I'm not sure about question b, but I'm pretty sure a is increase
Explanation:
I think I remember learning about this
Eccentricity in the orbit of the planet is the measurement of the deviation of the planet from its circular path. The maximum eccentricity of Earth's orbit increases the solar input and will alter the climate.
What is the effect and relationship of the eccentricity and climate?The eccentricity is the change or the modification of the elliptical orbit shape of the planet where it revolves around the sun. When there is the maximum eccentricity of the orbit then the solar input or the heat the planet receives will increase.
The solar heat or the input will increase due to the maximum eccentricity as the distance of the planet and the sun have changed and they have become more close, because of that the heat and solar energy will be more in contact with the planet's surface.
The increase in the eccentricity of the Earth’s orbit will affect the climatic conditions as the orbital distance has become close to the sun and the revolution has been affected and the climate is controlled and regulated by the heat emitted from the sun.
Therefore, an increase in the eccentricity of the Earth’s orbit will affect the climate and also increase the solar input.

hope that helped
DNA in the bones used to determine that the first scientist had misidentified the fossil.
What do you mean by fossils?Fossils are the preserved remains of plants and animals whose bodies were buried in sediments, such as sand and mud, under ancient seas, lakes and rivers. Fossils also include any preserved trace of life that is typically more than 10 000 years old.
There are four main types of fossils, all formed in a different way, which are conducive to preserving different types of organisms. These are mold fossils, cast fossils, trace fossils and true form fossils.
Fossils are the remains or traces of ancient life that have been preserved by natural processes. Examples of fossil include shells, bones, stone imprints of animals or microbes, exoskeletons, objects preserved in amber.

Answer: The answer would be Precipitation.
Explanation:
Which of the following statements is true?
Geocentric theory was initially rejected.
Bode's Law incorrectly predicted the location of Uranus.
The ocean is primarily made of chlorine and oxygen.
Cepheid variables can be used to determine the temperature of stars.
Answer:
Bode's law incorrectly predicted the location of Uranus should be the answer
Explanation:
The ocean is primarily made of chlorine and oxygen.
The Bode's law was one of the earliest laws in astronomy. Astronomy is the study of the celestial bodies and outer space. Bode's law has to do with the approximate distances of planets from the Sun. approximate distances of planets from the Sun.

tudy the arrow that is circled in the image.
The sun is in the sky. Clouds with blue arrows pointing down toward water. A circled arrow is pointing from the water inland. Red arrows are pointing up from the land to the sky.
What happens at this point?
Warm air is rising.
Cool air is sinking.
There is a difference in air pressure.
Cool air is less dense than warm air.
Dont answer with anything including arrow'S There is no S read it before answering
Answer:
The blue arrows in circles indicate that cool air is sinking
Explanation:
Warm air is less dense than cool air. For this reason, warm air rises, creating a low pressure region, and cool air, which is more dense than warm air, sinks creating a high pressure zone. In this description, the red arrows represent the hot air rising up to the sky, and the blue arrows represent the cool air sinking down. The reason warm air is less dense is because its molecules are further apart than when it is cold, making it lighter per cubed square foot.
So, we can conclude that option a) Warm air is rising is incorrect, because the warm air rising is represented by the red arrows pointing up form the land to the sky.
Options c) Cool air is less dense and d) warm air is more dense are also incorrect, because as mentioned before, cool air is more dense than warm air.

Two students are comparing scientific experiments to investigations. They came up with the following ideas.
Student A: Testing plant growth in different types of soils
Student B: Comparing the water level in a lake during different times of the year
Which student gave an example of a scientific experiment? (5 points)
Student A because it requires experimental and control groups
Student B because it requires a hypothesis
Student A because it is preferably done in natural settings
Student B because it is preferably done across a long period of time
Brainliest for correct answer :)
Answer:
Student A because it requires experimental and control groups
Explanation:
Student B merely compares the water level, while student b is looking for plant growth.
We can eliminate the second and last answer choices, knowing this, leaving the first and third answer choices.
A science experiment doesn't have to be in natural settings, therefore the answer is the first option!

Answer:
B. The Atlantic Ocean did not exist in earlier times.
Explanation:
It simply didn't yet exist; there was only Pangaea surrounded by a global ocean. Before the Atlantic Ocean could open Pangaea had to be split. ... Deep beneath the Atlantic's waves it erupts as lava, providing new crustal material as it slowly pushes the continental plates apart.

mark me my first brainliest?
The best example for law of conservation of energy is potential energy is used to create electrical energy and release light and thermal energy. Thus option b is correct.
What is law of conservation of energy?The law of energy states that energy can't be created nor be destroyed it only transfer from one form of energy to another form of energy.
In above example as we know that electrical energy is created by potential energy which stored in the form of water in dam after that electrical energy is produced so potential energy converted into electrical energy as a polly switch on the light she change the electrical energy into thermal energy because as we burn light it also develops some heat.
Therefore, we can say that energy is conserved and it only converted into one form of energy to another form of energy. Thus, option b is correct.
