moves upward.
A metal rod would not be a good choice for roasting marshmallows because
metal transfers thermal energy.

Answers

Answer:

O As the air around the campfire is heated and becomes less dense, it rises and moves upward.

Explanation:

This is true because, the convection transfer needs the particle of elements to transport the heat from where it is in abundance to where it is in less abundance. Just like a water boiling becoming hot at the point closer to the fire than the top of the pot, so also will the air around campfire transfer heated air from the place closer to the campfire to upwards aware from the fire.

Convection is the flow of air around the campfire when it is heated and the decrease in density as it rises upward in the atmosphere. Thus, the correct option is C.

What is convection of heat?

Convection is the transfer of heat from one place to the other due to the movement of fluids present in it. It is a distinct method of heat transfer in systems. The convective heat transfer involves combined processes of conduction and advection in a system and its surrounding. Convection is the dominant form of heat transfer in liquids and gases.

The thermal radiation in the fire is mostly in the form of infrared waves and visible light. However, the campfire heat transferred via convection shoots straight up in the sky and never reaches to the ground level.

Therefore, the correct option is C.

BRAINLIEST APPRECIATED

THANK YOU!

Answer:
B. Used by plants to make food

Explanation:
Chlorophyll is found in chloroplasts inside of cells. It’s a green pigment and it absorbs sunlight. The sunlight that is absorbed is then used in the process of photosynthesis. Photosynthesis is used by plants, algae, and some bacteria. It produces glucose or sugar, which becomes food for the organism.

Therefore, the best choice is B. used by plants to make food.

It is best in deep forests where dead organisms have not been disturbed.

Answers

Answer:

It gives useful information about environments and the ways past organisms lived

Explanation:

A fossil is basically any preserved remains or trace of any organism that once lived in the past. Bones, shells and exoskeletons are examples of fossils that can be studied through Paleontology.  

From fossil studies, we can tell how long these lives existed on earth and how varying plants and animals are related to one another. We can often find out how and the places they lived and their environments as well.

APT and photovoltaic cells are simikar because

Answers

The question is incomplete, below is the complete question.

ATP and photovoltaic cells are similar because

A. they are both key components of plant cells.

B. they both produce chemical and electrical energy.

C. they are both key components of solar panels.

D. they both use energy from the sun to separate electrons from atoms.

The correct answer to the question is option D

ATP and photovoltaic cells are similar because THEY BOTH USE ENERGY FROM THE SUN TO SEPERATE ELECTIONS FROM ATOMS.

Photovoltaic cells are otherwise known as solar cells,they are made of silicone that are specially treated,these specially treated silicon transfers solar energy gotten from the sun to electrical energy.

These solar powered photovoltaic panels converts the rays from the sun into electricity.this it does by exciting electrons found in silicon cells and also using the photons of light from the sun.

When this electricity is generated,it can be used to supply energy that is renewable to ones home or business.

In ATP, during the process of photosynthesis, sunlight penetrates the cell and further pass into the chloroplast. This light energy is further intercepted by granal stacks containing chlorophyll molecules, from then,some of those light energy are concerted to chemical energy,as this is going on,a phosphate is then added to a molecule to give rise to ATP.

For example, some cultures use nose shape as one of the defining traits for a racial group. Other cultures do not use nose shape in defining racial groups, but use hair color instead.

Ask at least 20 people what five traits they think are most important when distinguishing racial groups. Document the responses, and then review the data. Did every person use the same traits?

Explain why the steroid hormone estradiol (MW 272) readily crosses membranes by simple diffusion but the much smaller H requires transport proteins

Answers

Answer:

Estradiol has a higher partition coefficient than H+ ions

Explanation

Estradiol is a non-polar and hydrophobic molecule that has a higher partition coefficient than H+ ions, it means that the cell membrane is more permeable to this molecule because it can dissolve in and diffuse within the hydrophobic phase of the membrane. The movement of polar charged molecules (even small H+ ions) requires the input of energy to be able to dissolve within the lipid bilayer. In consequence, the movement of H+ ions requires proteins capable of transporting these protons through the membrane.

Answers

Answer:

Honestly I think it's C

Explanation:

The three main ocean zones are neritic, bathyal, and abyssal. Therefore, none of the statements are correct.

What are the three main zones?

The ocean is divided into three main zones which are the neritic zone. This zone is the shallowest zone extending from the shoreline to the edge of the continental shelf and is 200 meters deep.

The bathyal zone is the middle zone extending from the edge of the continental shelf to the abyssal plain and is 4,000 meters deep. The abyssal zone is the deepest zone extending from the abyssal plain to the ocean floor.

Apart from the three main ocean zones, there other oceanic zones are  epipelagic zone, mesopelagic zone, and hadal zone. The hadal zone is the deepest oceanic zone and is unique to highly adapted species of marine life and is important to study.

Therefore, the three main ocean zones are neritic, bathyal, and abyssal.
