Organisms get their energy from different sources depending on where they land in the food chain. This section on How Living Things Get Energy is going to talk about the two big ways that living things get their energy, Cellular Respiration and Photosynthesis.
First, we consider the parents:
Phenotypes: Polka dots
Genotypes: Pp
Using a punnet square,
P p
P PP Pp
p Pp pp
Therefore, out of four, the phenotypes and genotypes of the offspring will be as follows:
Phenotypes: 3 with polka dots (75%) and 1 with solid (25%)
Genotypes: 1 dominant homozygous (25%), 1 recessive homozygous (25%) and two dominant heterozygous (50%)
The answer is option D.
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.
