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.

Answer:
True
Explanation:
Geneticists have discovered that all human embryos start life as females. In the early development in the embryonic stage, this is true both for humans and mammals. This changes only at the 2nd month (in the case of humans, since different mammals have different gestating periods) if the embryo can elaborate enough androgens (dominant male hormone) to offset the maternal estrogens (dominant female hormone) then, maleness develops.
