How are tropical plants such as bromeliads adapted to the biome in which they live?
O A. They grow from tree branches rather than the forest floor, which helps them to absorb more sunlight.
OB. They have long, thick roots, which helps them to gather the nutrients that are found deep within the soil.
O C. They have hollow leaves and stems for storing water, which helps them to survive long periods with little rainfall.
O D. They lose their leaves during the winter, which helps them to save energy when the temperature falls and prevents the buildup of
snow.
What process is the driving force behind evolution?
Answer:
Mutations and natural selection are the main ones
Explanation:
The process that is the driving force of evolution is natural selection, as natural selection is the phenomenon that explains that nature selects organisms over time to survive in ecosystems.
What is the significance of natural selection over time?Natural selection is important for the survival of organisms as it is a process by which populations of organisms change over time in response to the outer environment. It is also an important evolutionary mechanism because natural selection always chooses the fittest and natural selection also drives the development of new species and helps ensure the survival of existing species.
Hence, the process that is the driving force of evolution is natural selection, as natural selection is the phenomenon that explains that nature selects organisms over time to survive in ecosystems.

to see them, while solid brown and solid white butterflies are easier to see and get eaten.
Explanation:
I don't know what the question is, but the spotted butterflies will reproduce more spotted butterflies and the solid coloured butterflies will not live, therefore not reproducing any solid coloured butterflies. This means the population of spotted butterflies will increase, but the population of solid coloured butterflies will decrease.
Bees see the colors yellow and blue, but not red. Flowers that need to be pollinated by bees are mostly yellow of blue. What type of evolution is that?
Answer:
Natural Selection
Explanation:
In natural selection process of evolution, traits that are essential for an individual to be fit enough to survive under environmental stress become dominant.
Since the flowers are of blue or yellow color, it is essential for a bee to be able enough to perceive the blue and yellow color. Hence, the eyes of bee with time have evolved to perceive these two color so that they can pollinate flower.
