Answer:
to digest the food
Explanation:
The main purpose of the digestive is to get the nutrients out of the food that you eat. When you eat something, it goes through the digestive system to get the fuel and nutrients from the food that you eat.
Water is a very polar molecule.
This means there is a (slight) difference in charge between the ends of the water molecule. Water is made up of an Oxygen and two Hydrogens (H₂O). The Oxygen is a much larger atom, with 8 protons in its nucleus, whereas Hydrogen has only 1 proton.
As protons are positively charged, the oxygen has a greater positive charged, so the electrons which are negatively charged are more attracted to the Oxygen, and the bond shifts slightly towards the oxygen. As the electrons have shifted position, the negative charge has shifted position, to there is a slight negative charge nearer the Oxygen, δ⁻ (delta minus), and a slight positive charge, δ⁺ (delta plus), at the Hydrogen.
This allows strong inter molecular forces to occur, as the slightly positive Hydrogens are attracted to the slightly negative Oxygens. This force of attraction between water molecules causes them to want to 'stick together', causing a high surface tension.
So the answer is B)
E. Weathering - Sometimes the Earth's crust is forced to pull apart into smaller sections or pushed back together. Because of the constant movement, rocks underneath are brought up on the surface. This movement of rocks is referred to as uplift. When a metamorphic rock undergoes this process, it may be subjected to constant wear and tear. The rock will weather and may crumble into smaller pieces.
The water will go from low concentration to high concentration spontaneous. So the solution would cause the cell swell means let the water goes inside the cell which the solution has lower concentration than cell.
<u>Answer:</u>
An example of non-renewable source of energy would be C) Nuclear power.
<u>Explanation:</u>
Renewable resources include biomass energy (such as ethanol), hydropower, geothermal power, wind energy, and solar energy. Biomass refers to organic material from plants or animals, whilst Nonrenewable energy resources include coal, natural gas, oil, and nuclear energy. Once these resources are used up, they cannot be replaced, which is a major problem for humanity as we are currently dependent on them to supply most of our energy needs.
I hope this helps! Have a great day! -Olli :]
