Answer:
D). genetic drift
Explanation:
Genetic drift is the change in an allele frequency over a period of time. This event has to be random and a chance event.
For example: In a population of a flowering plant there are two types of flowers, blue and yellow. Due to a fire many yellow flowers are destroyed by chance. Now the resultant population will have more blue flowers and when they reproduce the population will eventually evolve to have more blue flowers. Effect of genetic variation is more pronounced in a small population since its easy to disturb the allele frequency.
<span>The answer is Anemia—iron-deficient diet. Anemia is a result due to the lack of iron which caused the decrease of the number of red blood cells in the body. </span> If you do not have enough iron then it will result to fewer and smaller red blood cells in your body. As we all know, hemoglobin is used to carry oxygen, so when you lack hemoglobin,there is a lack of oxygen supplying for your body also.
Answer:
C
Explanation:
Mutualism is a relationship between two parties where <em>both parties </em>are benefited.
This means the answer would be C- "Ants feed on aphid wastes and protect the aphids from predators."
The <em>ants</em> benefit from a feeding source.
The <em>aphids</em> benefit from predator defense.
<u>In answer C, both parties are benefited, so this is mutualism!</u>
Answer:
C. In addition to being advantageous the allele also exhibits overdominance.
Explanation:
If the allele is advantageous and dominant over the other alleles, the individuals who own it will adapt better to the environment and most of their offspring will exhibit the attributes granted by the allele, which would increase its frequency in the population over time. In addition, individuals who own it will be more successful and more likely to reproduce than those who do not.
