The correct answer is option A- HIV virus.
HIV virus is an example of enveloped virus, that has the ability to infect a host cell by attaching itself to it and fusing with the host cell. Once infected, the virus leaves the host cell and moves to another cells to infect them. The HIV virus contains glycoprotein spikes to attach to the host cell.
Homozygous.
You can tell in future that if both letters are either lowercase or upper case (e.g. TT or tt) the answer is always HOMOzygous. If the letters are different cases (e.g. Tt or tT) the answer is always HETROzygous. This is because 'homo' means 'same' and 'hetero' means 'different'.
Random distribution is the probable distribution pattern of opossums.
Explanation:
The opossums are the member of low density population. They are sparsely distributed because of the low number. There are troubles for them to find a mate.
Their habitat makes them solitary as they have flexible dietary habits. they are terrestrial animals living in burrows and are nocturnal.
They have random distribution pattern. The opossums are distributed in the population as random. The mates in opossums do not have choices of mates and the environment conditions in which they live are stagnant.(having no social life). Random interaction is seen in <em>species which do not have any social bonding</em> between the species of the animals or plants.
Your nervous system quickly responds to the threat and sends a signal to your brain which causes your muscles/ body to react.
