Answer:
The correct answer would be the virus envelope.
Viral envelope is a protective covering present around the capsid proteins in some viruses.
It is usually derived from the cell membrane of the host and thus it is composed of lipid and viral proteins.
It provides stability to the viral particle, helps in protecting the viral genome, and aids in the fusion of the virus with the membrane of the host.
Examples of viruses in which envelope is present: herpesviruses, poxviruses, flavivirus, hepatitis D et cetera.
Examples of viruses in which envelope is absent: adenoviridae
, papillomaviridae
, picornaviridae
, caliciviridae et cetera.
The place where an organism lives
Answer: 1. 0.6 m/sec. 2. 6m/sec
Explanation:
Frequency = 0.1/sec wavelength = 6 m
speed = freq x wavelength = 0.6 m/sec
speed = distance/time = 60/10 = 6m/sec
Convergent evolution can occur when two different species adapt similarly due to their habitat and environment.
The right answer for the question that is being asked and shown above is that: "C. People can be tested for mutations on these genes." The statement that is true about BRCA1 and BRCA2 genes is that p<span>eople can be tested for mutations on these genes.</span>
