Answer:
B. a bowling ball
Explanation:
According to Newton's law of universal gravitation every body attracts another body by an amount of a force that is directly proportional to the product of the two bodies' masses and inversely proportional to the square of the distance between them. Knowing this then, it becomes clear that the body with the biggest mass will exert the greatest gravitational pull. From this list the ball with the biggest mass will be a bowling ball.
Ans.
<em>Viscum album </em>is a plant species, commonly known as mistletoe. It is a hemi-parasitic plant that grows on other trees.
Birds cause seed dispersal as they pick seeds from parent plant and drop them in other places. Seeds of mistletoe are sticky or viscous due to mucus and they provide nutritious food to the birds.
Hence, it can be concluded that the mistletoe seeds show adaptations primarily for seed dispersion, not for infecting the host plant.
Thus, the correct answer to be filled in the blank is 'is nutritious to the dispersing birds.'
