Answer:
Explanation:
In the Hershey and Chase experiment, they aimed to show where the phage DNA went when it exited the protein coat and entered the bacteria. In this scenario, the two student's approach won't work because amino acids (and therefore all proteins) also have nitrogen atoms which ultimately means that the radioactivity would not distinguish between DNA and proteins and the experiment will not provide the correct results.
Answer:
Darwin suggests that the strongest survive and adapt to produce even stronger more adaptable offspring
The correct answers (c.) punctuated equilibrium.Punctuated equilibrium is a mode of evolution that the certain foraminifera (shelled protozoa) represents. It is , in fact, the hypothesis of the evolutionary development of rapid episodes that is marked between long periods of little or even with no change at all.
Answer:
D) Each parent contributes one allele for this trait
Explanation:
All traits of individuals are determined by specific genes of that trait. For example, there is a certain gene for height, certain gene for eye color, face shape etc.
Genes are the units of hereditary, and for every trait there is one gene in every organism. However, one gene is present in two alternative forms called alleles in an organism. For example: There is a trait height, a person has two alleles for the height gene, one allele is for short height, and other allele is for tall height. The trait of tallness is dominant over the trait of shortness, Therefore, this person will have tall height.
Now the alleles are transmitted from parents to offspring. Every parent contributes one allele for a specific trait, in the process and transmit it to offspring.
The allele which will be dominant will be expressed while the one that is recessive will e suppressed.
Therefore, option D is the right answer.
Hope it helps!
Artificial selection - The intervention of humans ensures that only individuals with the most desirable traits produce more offspring
- Farmers only breed the livestock that produce the most food..... Cow, Chicken, plant with the most vegetables
