Tom tells Greta that his father, an astronomer, is planning a scientific experiment to study another galaxy. Using a powerful telescope, Tom's father will record data of shifts in light patterns every 30 seconds.
He will later study the data. Greta says that this is not an experiment. Which of these statements
supports Greta's statement?

A. This is not an experiment because it is not performed in a lab.

B. This is not an experiment because there are too many variables.

C. This is not an experiment because a variable cannot be manipulated.

D. This is not an experiment because it uses only theoretical predictions.

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).

hope it mark me as brainlieast.

answers are:

lysogenic     viral dna merges with host cell dna

lysogenic     no symptoms

lytic               viral dna takes over

lysogenic     virus does not destroy host cell

lytic               virus destroys host cell

lytic               induces symptoms of viral infection

lysogenic       cell reproduces and spreads provirus

which
