Properly identifying each species.
Accurately recording his findings.
Not interfering with ecosystem while studying the birds.
I think it’s C but I’m not fully sure so wait for others just to make sure
The vegetable oil is made up of chains of long fatty acids. These long chains of fatty acids are non-polar in nature, i.e, they do not interact through ionic forces rather by covalent forces. The phospholipids are also long chain fatty acids with an ionic head. The mixing of the vial of phospholipid in vegatable oil will lead to the formation of a micelle where the lipophilic ends of the phospholipid will be on the outside and the lipophobic end will be towards the centre of the micelle.
The endosymbiotic theory explains that mitochondria and chloroplasts descended from the same type of bacteria. Symbiosis is an interaction between two organisms of different species, and <u>endo</u>symbiosis is a type of symbiosis in which one organism lives <u>inside </u>the other one. According to the endosymbiotic theory, a host cell ingested symbiotic bacteria, which specialized into mitochondria or chloroplasts. The evidence for this theory is that mitochondria and chloroplasts, like bacteria, have their own circular DNA. They also have their own transcriptional and translational machinery.
Answer:
Scientist study moving forces, biology, chemistry, and any other natural or unnatural study.
