Answer:assuming it is LiAlSi2O6, you have lithium, aluminum, silicon, and oxygen. It’s difficult to tell with all of the letters capitalized. Only the first letter of the atom should be capitalized. A capital I is iodine.

Cellular Reproduction
Explanation:
" positive feedback loops push the organism further out of homeostasis, but may be necessary for life to occur. Homeostasis is controlled by the nervous and endocrine systems in mammals." (Lumen Learning)
Simple version:
First, the section with the desirable gene must be identified. Assuming that has already happened, the section of DNA must be excised from the original genome using restriction enzymes, which recognize certain DNA sequences and snip DNA at those sites. DNA ligase is used to "glue" these ends back together. The DNA is inserted into a plasmid (also with restriction enzymes), which would usually contain antibiotic-resistance genes (so they survive in an environment containing the antibiotic, which would also help show if the bacteria have been successfully transformed).
Then comes the actual transformation process. The bacteria to be transformed are mixed with calcium chloride (which causes the bacteria to be more receptive to the plasmids) and then mixed with the plasmids. The bacterial cells are subjected to a heat shock (the solution is heated and rapidly cooled, e.g. by placing the mixture in a hot water bath and quickly transferred to ice) so they will take up the plasmid (since the temperature change makes the membrane more permeable). The bacteria are placed on a growth medium containing the antibiotic they're resistant to. Only those successfully transformed would survive.
Answer:
2, 3 and 4 only.
Explanation:
Mutations refer to change in genetic content or alterations of DNA which might be as a result when the DNA is copied or due to environmental factors like Ultraviolet radiation.
Majority of mutations have neither positive or negative effects on organisms the occur and they are called neutral mutations.
An example is silent points mutations which does not alter the amino acids it's encode.
Some Mutations have positive effects and some have negative effects which cause genetic disorder.
