Answer:
plasmid
Explanation:
Plasmids are small circular double or singe stranded DNA molecules that are distinct from the main chromosomal DNA. They are used in genetic engineering as vectors for replication of foreign DNA or proteins using bacteria as a host organism. The DNA strand is integrated into the plasmid DNA to form a recombinant plasmid that is then transformed into the host.
Plasmids are ideal vectors because of the following characteristics:
- High copy number per cell
- Multiple cloning sites
- Have an origin of replication
- Have antibiotic resistance gene
There are also diffrent types of plasmids:
- Degradative
- Virulence
- Resistance
- Fertility
- Col plasmid
Answer:
Sodium and lithium are in the same group of the periodic table; this is because they both have the same number of electrons in their outer shell (1 as indicted by the group number). this commonality is the reason they have similar chemical properties. As we go down the group however, the electronic structure of atoms of an element changes as that there are a increasing numbers of ‘shells’.
Electron ‘shells’ are filled according to ruled of quantum mechanics however to simplify things in this case the first shell can fit 2 electron, the second 8, and the third shell 8. Lithium has 3 electrons, hence it the first shell is filled, and 1 electron occupies the second shell. Whilst Sodium has 11 electrons, hence its first two shells are filled and the third shell is occupied by one electron.
To expand on this question, the duet/octet rule is a rule in quantum mechanics that observes that main group elements tend to be stable with a full outer shell.
This explains why sodium and lithium is found in the form of Li+ and Na+ ions in nature.

Answer:
Genetic Engineering
Explanation:
Genetic Engineering is the process of gene modification, it manipulates the genes of a particular organism. In this case the fish had its gene's modified to include the gene of the jellyfish that allows it to glow
Answer:
Assuming you mean in a compound of elements: A name is just what you call it, and the chemical formula is what elements it is made of.
Explanation:
Take sodium chloride (Salt) for example. It's name is sodium chloride, but its chemical formula is NaCl. Na= Sodium, and Cl = Chlorine. So one sodium ion and one Chlorine ion create NaCl. Na+Cl=NaCl. And the name for the product of the formula is Sodium Chloride.
Another example is H2O (Water). H=Hydrogen and O=Oxygen. There are 2 hydrogens and one oxygen in H2O. H+H+O=H2O. The name for the formula is water.
1- starts with bare rock
2- takes longer than Secondary succession
3- Volcanic eruptions, glaciers, explosions etc are some ways it starts
4- starts after a disturbance
5- it’s the process of changes in an ecosystem
I hope those are good!
