Answer:
The cells circulate in the atmosphere, then joining together, and eventually, they clusters, (clouds) get too heavy, and rain falls.
Explanation:
Answer:
transport of substances across a biological membrane through a concentration gradient
Explanation:
if im wrong im deeply sorry, im not good at this but ill find an internet explination>
<h2>Main Difference – Simple Diffusion vs Facilitated Diffusion
</h2><h2>Simple diffusion and facilitated diffusion are two types of passive transport methods in which the cell membrane transports molecules across it. It uses natural entropy to move molecules from higher concentration to a lower concentration until the concentration becomes equalized. Hence, no ATP energy is used for the transportation of molecules. There are four main types of passive transport: osmosis, simple diffusion, facilitated diffusion and filtration. The main difference between simple diffusion and facilitated diffusion is that simple diffusion is an unassisted type of diffusion in which a particle moves from higher to a lower concentration across a membrane whereas facilitated diffusion is the transport of substances across a biological membrane through a concentration gradient by means of a carrier molecule.</h2>
Light travels as a wave. But unlike sound waves or water waves, it does not need any matter or material to carry its energy along. This means that light can travel through a vacuum—a completely airless space. ... It speeds through the vacuum of space at 186,400 miles (300,000 km) per second.
Biotechnology is the exploitation of biological processes for industrial and other purposes, especially the genetic manipulation of microorganisms for the production of antibiotics, hormones, and stuff.

ooh I know the others
artificial selection is humans selecting two different species or breeds and making them... you know... and then a new combination is born! Usually is used for agricultural purposes, like new and better cows, or for scientific purposes like the Liger.
A Clone is a being with the same exact DNA structure of the previous Being, and they are usually created with a single mother.
Answer:
What proteins,DNA, fat and sugar have in common is that they are biomolecules, or organic molecules, which all contain carbon and are necessary for the vital functions of living beings.
Explanation:
The principal biomolecules of living beings are proteins, carbohydrates or sugars, lipids and nucleic acids, such as DNA. All these molecules contain carbon in their composition and have hydrocarbon structures that may also have oxygen, nitrogen, sulfur and phosphorus in their composition.
Each of these biomolecules has a specific function and is indispensable for the development of life:
- <em><u>Proteins</u></em><em>: they are composed of amino acids and participate in the constitution of tissues, metabolic processes and the regulation of organic functions.
</em>
- <em><u>Carbohydrates</u></em><em>: they are the main energy substrate, participating in the metabolism that leads to obtaining ATP.
</em>
- <em><u>Lipids</u></em><em>: they are the main constituent of cell membranes, as well as constituting other organic molecules and being a reserve energy source.
</em>
- <em><u>Nucleic acids</u></em><em>: DNA and RNA participate in the process of storage and transmission of genetic information, being responsible for processes such as the synthesis of proteins and other molecules.
</em>
<u>The characteristics that have in common proteins, DNA, lipids and carbohydrates are their carbon-based composition, being organic molecules and being essential for living beings</u>.
