That was correct. it was letter choice b
Answer:
Identifying the fossil is the first step. We have already identified this fossil as a clamshell. We know clam are from the sea, but if you didn't, you could conclude this from knowing where you found the fossil (likely near the beach). Discovering where it is can also lead you to a conclusion on it's arrival as a fossil, perhaps washed up on shore or buried by an animal.
Explanation:
I choose the option C.
N2 + 3H2 = 2NH3
Yearly rainfall-12–30 inches; mild summers, cold winters are considered as weather conditions.
<u>Explanation:</u>
To understand the basic difference between the weather condition and climate let’s look into the basic difference. Weather condition is the condition that is been experienced whereas the climate is a condition that is expected to be happening for a long period of time.
Here mild summer and cold winners are the weather condition of that place. Climate will be the average weather of that particular region. While weather is the condition observed during that particular period climate is the condition observed for years together.
Answer:
D) Because sticky ends can be temporarily held together by hydrogen bonding between the two strands.
Explanation:
Restriction enzymes cut the DNA at specific restriction sites and by the mechanism of action they can form two types of ends:
- sticky ends-single-stranded overhangs are formed
- blunt ends-without overhangs.
The main advantage of sticky ends (their overhangs) is that they can complementary bind to another overhand formed by the same restriction enzyme. So, for example in cloning, if the DNA of interest and plasmid vector are cut with the same restriction enzyme, that forms sticky ends, fragment of DNA will fit into a bacterial plasmid in one direction.
On the other hand, blunt ends can be inserted into vector in both directions: head-to-tail or tail-to-head.
