The Earth would then intern become way too hot.
At the moment the sun provides just the right amount of heat to sustain all life on Earth, if the Earth absorbed all of the heat from the sun, the temperature would increase dramatically, leading to extreme heat. That would also lead to pretty much everything on the planet to die.
Hope this helps! :)

An element is a substance made up of only one type of atom. It is the simplest form of matter and examples include hydrogen, oxygen, gold, and silver.
A substance that is made up of only one type of atom is an element. Elements are the simplest form of matter that cannot be broken down into simpler substances by ordinary chemical means. Examples of elements include hydrogen, oxygen, gold, and silver, each comprising only one type of atom. On the other hand, compounds, mixtures, and solutions can be comprised of more than one type of atom, molecule, or substance.

Whiskers and beaks are two examples of _____. electroreceptors mechanoreceptors olfactory receptors photoreceptors
Whiskers and beaks are two examples of olfactory receptors. An olfactory receptor is a smell receptor that contains a protein capable of binding odor molecules that plays the central role of smell.
Answer:
its mechanoreceptors
Explanation:
mechanoreceptors react to pressure and distortion.
Explanation:
Acid rain is caused due to increase in nitrogen oxide and sulfur oxide into the atmosphere.
The amount of these oxides increases into the atmosphere due to increase in pollution.
Therefore, pollution is caused by humans. For example, pollution from sources like vehicles, industries, factories, labs etc leads to increase in the development of harmful gases.
Thus, the statement acid rain is caused by human activity is true.
B.Exocytosis
C.Osmosis
D.Endocytosis
Answer:
A. Diffusion
Explanation:
A.Diffusion - this is correct. Diffusion is the process where small molecules enter the cell by moving from a high concentration to a low concentration through a semi-permeable membrane.
B.Exocytosis - this is incorrect. Exocytosis is a cell transport mechanism where the cell uses a system of vesicles to transport cargo outside of the cell. The vesicles fuse to the cell membrane and deliver the cargo outside.
C.Osmosis - this is incorrect, osmosis is a type of diffusion specific to water molecules
D.Endocytosis - this is incorrect. Endoocytosis is a cell transport mechanism where the cell uses a system of vesicles to transport cargo into the cell. The cell membrane engulfs the molecules and brings them into the cell via the vesicle
