Answer:
They are effective for long periods of time
Explanation:
Alpha and Beta interferons are part or form of Interferons. The Alpha interferons is derived from leukocytes infected with virus, while the Beta is derived from fibroblasts infected with virus.
Both of them have various mechanism of action including:
1. they bind to the surface of uninfected cells.
2. they initiate manufacture of antiviral proteins.
3. they disrupt stages of viral multiplication.
4. they initiate transcription.
Hence, in this case, the correct answer is "they are effective for long periods" because they are not.
Answer: 1. True
2. Between six and right hours
Explanation:
1. Energy simply refers to the ability to do work. It's the strength that's required to be able to sustain a mental or physical activity.

2. Even though the hours of sleep that's used by people typically varies, adults generally need about six to eight hours of sleep.
Answer:
The answer is option A "4 chamber stomach = behavioral and chewing cud = internal structural"
Explanation:
Goats and other ruminants do not digest food directly as they eat their food and the reason is that ruminants do not have the enzymes that are necessary for breaking down the food directly as they eat so digestion in ruminants and particularly Goats has to undergo processes or procedures before the final digestion takes place.
All the processes in digestion for ruminant animals takes place in their four chambered stomachs which are the Rumen, Reticulum, Omasum and Abomassum.
In the four chambered stomach of Goat, the type of adaptation is behavioral and chewing cud which is the internal structure.
Answer:
Helix formation would be favored at high pH.
Explanation:
Hello! :)
It would take forever listing all the animals that have adaptations that helps them survive in their environment.
Natural selection is the process by which individuals with characteristics that are advantageous for reproduction in a specific environment leave more offspring in the next generation, thereby increasing the proportion of their genes in the population gene pool over time.
Hope this helped and I hope I answered in time!
Good luck!
