Answer:
The correct answer is - B. The seeds are in berries that are eaten by birds and dropped as waste away from the plant.
Explanation:
The mountain ash trees contain red berries fruits that attract birds and other organisms. These birds eat these berries and eat berries and fly over the hills or mountains and after digesting they drop the seeds of these berries with the digestive waste. These berries grow on the mountains far from the original source as birds carry them by flying away after eating.
Thus, the correct answer is option B.
An animal cell lacking carbohydrates on the external surface of its plasma membrane would likely be impaired in CELL TO CELL RECOGNITION.
Carbohydrates have diverse functions, one of their functions is that they serve as a recognition signal at the surface of cells.
Carbohydrates located on the surface of cells enable cells to recognize and communicate with one another.
Answer:
<u>No, there is no control group.</u>
Explanation:
To test various theories, experiments are usually conducted under a number of different conditions. Several considerations must be established when planning studies to ensure reproducibility, accuracy, and validity of findings.
For example, while controls are kept constant, or unmanipulated. Also, separate independent variables are strictly altered and analyzed - this guarantees validity and may show whether external influences affected the experiment. Here the variable being altered or measured is the food, and the resultant weight is the factor being observed.

create entirely new alleles in a population), random mating, random
fertilization, and recombination between homologous chromosomes during
meiosis (which reshuffles alleles within an organism's offspring)</span>
That answer would be no. because not all of them are the same.
