HELP ME PLEASE I BEG YOU I RELLY NEED IT URGENT !!!! 15 points!

Answers

Answer 1

Answer: The easiest example here is a computer/laptop... e.g. when the CD-ROM is spinning when you are perhaps playing a movie, the kinetic energy causes friction, which results in heat. All computers need a fan to prevent them over-heating for this very reason. Therefore heat is lost and energy is wasted.

Another example is a lightbulb. When a light is switched on and left for a long time, the current flowing through the filament (the thin bit of wire in the bulb) causes heating (due to electron-ion collisions but you may not need to know that) so energy is wasted as thermal energy instead of light energy.

These are just a few examples but other ones you could use are tv screens, kettles, toasters, etc :)

This because some animal diseases, such as rabies, can also infect people. So preventing the spread of these diseases in animals makes the diseases less likely to be spread to humans.

Which statement best describes one way a large body of water such as an ocean influences climate

Answers

Cool ocean air can cause a cooler climate.

Explanation: An ocean is a very important abiotic factor in any environment and has impacts on the climate of the environments it is found. The ocean currents are driven by the global wind system, which is powered by the energy of the sun. These currents transfer heat to the polar regions from the tropics and brings about the sooling of their environment, thus giving rise to cool climate.

Help please!What is the source of the carbon atoms in a plant's cells?
A)
they were created as the plant grew
B)
the Sun
C)
water molecules
D)
the environment

Answers

Answer:B. The Sun

Explanation:

Final answer:

The carbon atoms in plant cells derive from carbon dioxide in the environment through the process of photosynthesis, where it is converted into glucose and used to build cells.

Explanation:

The carbon atoms in a plant's cells primarily come from the environment, particularly from carbon dioxide in the atmosphere. This is absorbed by the plant through a process known as photosynthesis. In photosynthesis, plants use sunlight to convert carbon dioxide and water into glucose - a type of sugar - and oxygen. It's this glucose that provides the carbon atoms for the construction of plant cells. Thus, the correct answer to your question is D) the environment.
