I believe the answer is echinodermataechinodermata and Chordata have a very similar embryonic development
The answer is A because air expands when heated. The expansion of the air will “pop” out the dent from the inside.
DNA helicase- Unwinds the DNA strand in preparation for replication.
DNA polymerase- Replicates the base pairs of the strand, producing a new strand of DNA.
DNA ligase- Reconnects the severed DNA strand after replication.
Answer: 1) jet streams are like rivers of wind high above in the atmosphere. these slim strips of strong winds have a huge influence on climate as they can push air masses around and affect weather patterns-- they form a bond between hot and cold air
2) lifting along fronts: when air masses interact. lifting also occurs along frontal boundaries as air masses of different temperature and moisture content interact with each other. the lifted air cools and the water vapor condences to form clouds in advance of the surface warm front
3) when the temperature difference between the cold and warm is large, thunderstorms and even tornadoes may form. thunderstorms can form at a cold front or within air masses. at a cold front, air can be forced upard quckly. within an air mass, uneven heating can produce convection and thunderstorms
