Answer:
The water cycle describes the continuous movement of water as it makes its way from the ocean, to the atmosphere and back down to earth again.
Explanation:
Answer: The last choice, Gravitational Pull would become weaker and weight would decrease because when out of Earth's atmosphere, objects (also animals & humans) are able to float because there isn't really a gravitational pull, and because there isn't a gravitational pull, the weight changes and it is less than it was before. But mass never changes.
the air and all the gasses
The correct answer is: D.carrying messages to other cells
• Allowing polar molecules to enter the cell - Membrane proteins can be involved in transport. This kind of proteins are called channel proteins and usually are integral, transmembrane proteins of the membrane (span across the bilayer). Channel proteins are responsible for facilitated diffusion and active transport of the molecules.
• Recognizing other types of cells- Membrane proteins may function as markers for cellular identification (recognition) and may connect and join two cells together
• Receiving messages – Membrane proteins are often receptors for peptide hormones and thus involved in signal transduction.
Ribose sugar is only found in RNA, DNA has Deoxyribose. The D in DNA stands for Deoxyribose.
