Study the image.

a house on a beach near the ocean. point 1 is over the house, arrow is pointing up. point 2 is over the ocean, with arrows pointing away from the land. point 3 is over the ocean with the arrow pointing down. point 4 is in the ocean with arrows pointing toward land.

what do the arrows at point 3 indicate?

cool air is above water.
warm air is above land.
warm air is cooling quickly.
cool air is warming quickly.

Warm air is cooling quickly is the answer. My think is the arow is pointing toward the "cold" sea and usually when thinks are pointed down it means its getting less then or colder.

when a reversible reaction is occurring in both directions at the same rate; the products and reactants do not change in concentration. a chemical reaction where the compound is broken into its constituent parts.

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
