Answer:
Improved food sources
Explanation:
Artificial selection is also known as selective breeding. Its a deliberate process of breeding plants and animals for better breeds.
It's also called genetic engineering.
This in a way impacts the society positively as crops with better yield are produced. Example is wheat that has more grain or in animals, cow that produces more milk.
Answer:
low level of calcium would result in fewer signals sent between pre and post synaptic cells.
Explanation:
The calcium has a main role in signal transmission mechanism and here is the mechanism :
1-the impulse reaches the synapse (depolarization which is a voltage change).
2-the voltage gated calcium channels open and let calcium flow into the cell.
3-the calcium causes the synaptic vesicles to rupture and release chemical transmitters which cross the synaptic cleft and finally bind to receptors on the post synaptic cell (transmitting the signal)
so it's obvious that if calcium concentration decreases, the signal transmission also decreases.
That's the function of the nucleus.
The nucleolus makes ribosomal subunits from proteins and ribosomal RNA, also known as rRNA. ... Ribosomes make proteins; therefore, the nucleolusplays a vital role in making proteins in the cell. Function of the Nucleolus. Ribosomes are made of two subunits, a large and a small
To create a positive environment can help implement the principle of non-maleficence as well as guaranteeing that bullying or diminishing does not take place. When important decisions are to be made they should be shared with everyone trying to make the information accessible to everyone equally.
