Which moon phases are direct opposites of each other in both appearance and position?

New moon and Full moon

Explanation:

The phase of the moon refers to the time when the Moon appears to be in a particular shape relative to the position of earth and sun. The different stages of the moon are such as-

It starts initially with the new moon through sequential events which are crescent (waxing), 1st quarter, gibbous (waxing), and further continue with the full moon, gibbous(waning) and last quarter and the cycle repeats again with the new moon.

In the case of a new moon, the moon is not visible because of the exposure of the unlit half of the moon. It takes place when the moon comes in between the Sun and the earth. It is usually marked by the occurrence of a solar eclipse.

The full moon phase refers to the fully exposed, lit part of the moon. It takes place when the moon is oriented towards the opposite end of the earth from the Sun and is often marked by the occurrence of a lunar eclipse.

Thus, the phases of the moon that are directly opposite to one other in terms of both appearance and position are the full moon and the new moon.

i believe the correct answer is the virus gets an envelope that contains host molecules when it leaves the host cell.

explanation:

during the bidding/release stage of a virus, it encapsulates itself with part of the membrane of the host cells in this case the cells of the monkey and is the reason as to why the scientist found the genetic material of the monkey on the viral cell surface.

further explanation

to understand this answer, we have to know the cycle a virus undergoes to replicate. a virus is basically a bunch of genetic material enclosed in a capsule and lacks any machinery or organelles to ensure their survival so they must enter a host cell in order to get the environment needed to survive. some viruses enter and lyse(destroy) the host cell after they have replicated and undergo the lytic cycle while some enter and leave the cell intact after replicating and these undergo a lysogenic cycle. to enter the cell, they undergo the first process called attachment by binding to specific receptors and co-receptors on the surface of the host cell. after attaching to the cell, they start the second phase called penetration where virus enters or is engulfed whole by the host cell through a process called endocytosis. it is the same process that a cell takes up materials it needs or pathogens around it. uncoating of the virus then happens after the virus has been engulfed and is the third stage. the virus then undergoes releasing of its genetic material in the host's matrix.   the materials then enter the nucleus and undergo biosynthesis by adding themselves in strands of rna being translated and then copies of the virus are produced in addition to the host genetic material. the material/newly formed viral material then undergoes assembly inside the host cell and form a capsule around them. the virus undergoes the last release/budding stage by binding to the host membrane and pushing outwards. in doing so when they tear away from the host membrane, they pick up the genetic material from the membrane of the host cell to form their envelope.
