No, this is false some invasive species help balance out populations but then again it may sway out of control again. Also, not all invasive species have a negative impact on the ecosystem.
Answer:
Tobacco smoke contains dozens of carcinogens, including nicotine and formaldehyde. Exposure to tobacco smoke is the leading cause of lung cancer. Some chemicals that were previously added to foods, such as certain dyes, are now known to cause cancer.
It is important for a scientific claim to be accurate because a scientific claim is supposed to be able to be trusted and it needs to be credible. To develop a scientific claim you need to first test your theory many times to make sure that the same result happens every time.
Hope this helps
The correct answer is taxonomy,
Taxonomy is a branch of biology that aims to to sort living thing into categories. In its early years, taxonomy was solely based on structural comparisons, mostly the anatomical similarities and differences between the organisms. However, with the discovery of the physiological processes and the genetic structures of organisms, the previous taxonomic knowledge was revised and changed in the light of the new scientific finds. Nowadays, taxonomy is primarily based on genetic similarities between the organisms.
The structure that they are showing is the general structure of an amino acid. If you look at the left side there's NH2 (an amino group). On the right side is COOH (a carboxylic acid group) and the R is the part that varies depending on the amino acid --this way you can make up the 20 different amino acids but all with the basic structure shown in the diagram.
