Answer:
1. DNA-A.Double stranded molecule that has a deoxyribose sugar.
2. Helicase- C. Enzyme that breaks hydrogen bonds to unwind and unzip DNA
3.DNA Polymerase- E. Enzyme that covalently bonds sugars and phosphates during DNA replication
4.DNA Replication-B. The end-product of this process are two identical copies of DNA.
5.Pyrimidine-D. Nitrogen containing base that has a single ring as its molecular structure. Thymine and Cytosine are an example of this type of molecule.
Explanation:
The term migration fits the definition of a species brought into an ecosystem where it doesn't naturally occur
If there is less water in the bottle, then the note played is lower because there is more air to move around.
Using two different media (air and water) in glass bottles show how the speed of vibrations affects pitch.
Pitch is the way that your ear and brain order sounds based on their frequency (vibrations per second).
Rapid vibrations (high frequency) that reach your ear are categorized as a "higher" pitch, while slower vibrations (low frequency) are categorized as a "lower" pitch.
When you tap a glass of water with a pencil or spoon the water molecules vibrate and create sound waves through the water. More water means slower vibrations and a deeper tone.
The bottle with the most water will have the lowest pitch while the bottle with the least water will have the highest.
When Wanda and Marita blow across the top of the bottle, they set the air molecules vibrating and produce sound waves. In this case, more water results in a higher pitch, as opposed to tinkling the bottle. When the bottle has a small amount of water in it, the air molecules have lots of room and vibrate slower. Adding more water gives them less space to vibrate in, making them vibrate faster and producing a higher pitch.

Answer:
The correct answer is option B) "habitat isolation".
Explanation:
The two populations of ticks herein described have preference in one of two populations: either over mule deers or white-tail deers. One term that might be applied to describe these populations is habitat isolation. Habitat isolation occurs when the chances of mating between individuals of the same species are lowered because of differences in habitat preference. This is the case for the two populations of ticks, where because of differences in host preference, the ticks that feed from mule deers are isolated from the ones that feed from white-tail deers and vice-versa.
