Answer:
D- The effect of drift on average fitness is not predictable
Explanation:
Genetic drift is a mechanism causing change in allele frequencies in a population from one generation to another. Genetic drift happens by random sampling and the benefit or harm of the allele is not a factor in deciding which allele stays and which is deviated from.
A beneficial allele may be lost, and a harmful allele fixed into the next generation. Genetic drift affects both small and large populations but its effect is more pronounced in small populations.
Since Genetic drift happens by chance and any allele can be selected, the effect of the drift on the fitness of the population cannot be predicted. If a harmful allele is selected, there will be a negative effect on the fitness. On the other hand, if a beneficial allele is selected, there will be a positive effect on the fitness of the population
Although the work seems fancy, exocytosis is the just the release of substances from a cell with a vesicle. One situation may be the release of enzymes. Other situations are the releasing of neurotransmitters or exocytosis to add glycoproteins to the cell membrane.
A major function of the roots of a plant is to absorb water to produce food for the organism. They need water to produce the glucose product of food, the other reactant is carbon dioxide. This is the process of photosynthesis. The other product is oxygen
- Oxygen, substance all organisms require to survive.
- Glucose, substance produced and used by plant organisms for food.
- Reactant, substances used to make products.
- Carbon Dioxide, gas found floating in air, used by plants to make oxygen.
- Photosynthesis, the process where plants use their chlorophyll to make substances like food
