Answer:
c. daytime conductive heat gain from adjacent ground surface would be greater
Explanation:
The plants in the tundra had to adapt to survive so they became short and developed closer together, this can create a sort of cushion that locks in the heat that the sun can provide, conductive heat from the adjacent soil is also taken advantage of and the leaves on the plant absorbe as much heat from the sunlight as they can, growin closer together also helps them mantain the heat.
Either a. Or d. Cause they can be reversible but !usaly inhabition in enzymes doesnt bind so ide guess a.
The answer is 'cooler'. The Cretaceous Period was relatively warm and was experiencing global warming. However, a cooling trend was evident towards the end of the Cretaceous. The Paleocene followed the meteorite impact that resulted in the extinction of most of the dinosaurs. It is thought that dust particles in the atmosphere resulted in cooling during the early Paleocene.
Answer:
c. one helix strand that runs from the 5' to 3' direction and the other strand runs from the 3' to 5' direction.
Explanation:
A DNA molecule has <em>two strands of nucleotides with a sugar phosphate backbone each, but orientated on the opposite direction </em>allowing for the base pairs to complement one another, making it a more stable structure. <em>When two biopolymers run parallel to each other but with opposite directionality (alignment) we have an antiparallel arrangement.</em>
