Remember this:
atomic mass= atomic number + number of neutrons
The atomic number (same thing as number of protons) in this case is 15. The atomic mass is 31.
So, we subtract 15 from 31 to find the number of neutrons.
31-15=16
16 neutrons!!!
<span>In the cytoplasm, ribsomal RNA (rRNA), a type of RNA, and
protein combine to form a nucleoprotein called a ribosome. The ribosome
serves as the site and carries the enzymes necessary for protein
synthesis. They are often takes the shape of small round particles
attached in the endoplasmic reticulum. The ribosome attaches itself to m-RNA
and provides the stabilizing structure to hold all substances in position as
the protein is synthesized. Several ribosomes may be attached to a single RNA
at any time. <span> </span></span>
Answer:
His displacement is 0 km because he ends his walk where he started. The total distance of his walk is 20 km because he walks 10 km to the store + 10km back home.
Explanation:
Hope this helps:)
Carbon, Nitrogen, and Oxygen all have the same number of energy levels because periods (rows) tell the amount of energy levels an element has.
Answer:
Loss of biodiversity in the wetlands.
Explanation: Pollution can be defined as the emission of toxic, poisonous and harmful chemical substances which are capable of causing environmental degradation and contamination.
Nitrogen pollution enters Earth’s freshwater resources from a variety of human activities, including the use of fertilizers and pesticides in agriculture. This nitrogen pollution has a negative effect on plants and animals living in fresh water. Certain wetland plants, however, are able to purify the water and restore it to its non-polluted state.
Hence, what would most likely increase the negative effects of nitrogen pollution is a loss of biodiversity in the wetlands i.e the various species of animal and plants.
