Question

s1 retake practice test: characteristics of life
a scientist classifies something newly discovered as bacteria, not a virus. which evidence sources support this classification? select all that apply
the genetic material (dna/rna) is enclosed in a capsid
it has flagella for movement
it is an autotroph containing chloroplasts to enable photosynthesis
it can be killed with an antibiotic

Explanation:

1. Viruses have genetic material enclosed in a capsid, so this is not evidence for bacteria.
2. Bacteria can have flagella for movement, which viruses lack.
3. Some bacteria are autotrophs with chloroplast - like structures for photosynthesis, while viruses are not autotrophs.
4. Antibiotics can kill bacteria but not viruses.

Answer:

It has flagella for movement
It is an autotroph containing chloroplasts to enable photosynthesis
It can be killed with an antibiotic
