Answer:
The options are not shown, however the attached picture should show the parts of an atom and the relationships between the three basic parts of an atom being Protons, Neutrons and Electrons.
In the nucleus of an atom, there are both Neutrons and Protons whilst the rings of the atom will contain the electrons.
The protons carry a positive charge and the electrons a negative one.
When the protons and neutrons are added together, these will give the mass number of the atom so the mass number of this atom is 32.
For a neutral atom, the Protons and the Electrons should be equal. Notice how there are 16 protons (+) in the nucleus and 16 electrons (-) on the rings.
<span>Answer: Permeability. </span>
<span>This property allows liquids to pass through the material but also filters out
pieces of garbage and other pollutants. In aquifers, permeable rocks or
synthesized permeable material are used so that trash, or clay will not leak
into the groundwater. </span>
Answer:
RNA viruses
Explanation:
have genome composed of RNA that encodes a number of proteins.
Facilitated diffusion is the process of moving molecules across the membrane with the help of transport proteins to make the transportation of the molecules a lot easier and smoother.
Simple diffusion, however, does not have the assistance of transport proteins. Simple diffusion takes place when molecules move from a high concentration (of said molecule) to a low concentration.
The difference: Facilitated diffusion has the help of transport proteins while simple diffusion does not.
Hope I could help! If this isn't the answer you are looking for, or just...completely wrong, please let me know!
I believe:
Restriction Enzymes, and DNA Ligase
These enzymes cut n paste DNA, to produce a molecule of recombinant DNA, such as the red fluorescent gene used in ABE. These enzymes are used in the first step of DNA Cloning.
Hope this helps!!!!!
