Answer:
a) is present in honhuman primates but not humans, because humans lost this feature.
Explanation:
The opposable big toe is a trait that helps to primates to climb trees easily. Humans' ancestors started to walk in two legs, this created a needing for better stability, so a fixed toe became to evolve to allow our bipedal locomotion.
Therefore, options b and c are wrong. Option d is wrong too because it implies that the group "primates" is newer than "humans", and in fact, "humans" is part of the group "primates", so this is not the correct answer.
<span>Viral reproduction is termed viral replication. Viral replication is the term used by virologists to describe the formation of biological viruses during the infection process in the target host cells. Viruses must first get into the cell before viral replication can occur. From the perspective of the virus, the purpose of viral replication is to allow production and survival of its kind. By generating abundant copies of its genome and packaging these copies into viruses, the virus is able to continue infecting new hosts. Replication between viruses is greatly varied and depends on the type of genes involved. After replication of the virus has occurred, the virus will generally exhaust all the cellular resources, leading to cell death and the next step of the viral life cycle: viral shedding. However, a virus may choose, depending on the virus and environment, to instead become dormant within the cell, to emerge later. This would be deemed viral latency.</span>
