Answer:
<u>Nutrition and health benefits</u> are the most likely motivation ,if a person decides to switch from drinking freshly squeezed orange juice to calcium-enriched orange juice after a yearly checkup,
Explanation:
As the Calcium enriched orange juice contains calcium almost equal to that of milk , hence it is an essential mineral which helps in building and maintaining strong bones and teeths.
It is also an excellent source of vitamin D helping the body to absorb more calcium . Thus providing excellent nutrition and health benefits.
Hence <u>Nutrition and health benefits</u> are the most likely motivation
Answer:
Radiation leads to mutations that causes genetic drift and decrease fitness.
Explanation:
Radiation is responsible for changing or altering the DNA sequence within a cell.
Radiation either causes mutation or it leads to cell death.
Most of the ionizing radiation causes mutation within the deep inside of our cells which eventually leads genetic drift which means change in the frequency of the allele in a population over time.
Beneficial mutation confer advantage to the organism. But in this case, the mutation is not beneficial and decreases the fitness of the rodent organisms.
Answer:
Ferns
Explanation:
Ferns -
- These the species of plant , that are found in the shady and rainy areas .
- These classification of plant have a separate gametophyte, and sporophyte generations , where , the sporophyte is dominant .
- No seed plants .
Hence , the correct answer according to the information given in the question is , Ferns .
Answer:
The homozygous dominant phenotype is higher than expected, indicating that evolution has occurred.
Explanation:
At the start there are 200 fishes in the pond, 100 of them are AA(50%) and 100 of them are aa(50%). Using the Hardy-Weinberg Equilibrium equation we can say that the gene frequency is
A=0.5
a=0.5
With those frequency, the expected percentage of offspring with dominant genotype will be:
AA= 0.5 * 0.5 = 0.25 = 25%
The number of homozygous dominant found is 35% which is higher than expected (25%). Higher homozygous dominant frequency than expected means the Hardy-Weinberg Equilibrium is changed. In this case, evolution probably the cause that shifts the gene frequency.
