Ou are on an expedition in a tropical rainforest. You notice a tall plant with large, long, conical purple flowers that produce nectar. When you ask your guide about the plant, she pulls out a large pink fruit from her bag and explains that it is from the plant with the purple flowers. After tasting the fruit, you decide to bring the plant back home and cultivate it in a greenhouse. You remember seeing a particular butterfly on the purple flowers during your trip to the rainforest. After obtaining a few of these insects, you release them into the greenhouse. A few weeks later, the pink fruit plant is growing! In the process, though, a few butterflies have escaped. Is this an environmentally safe situation? Yes, the butterflies eat only nectar, so the ecosystem will not be disturbed. No, the butterflies may not have a natural predator in this environment; thus, they could displace native species that consume nectar. Yes, the butterflies will aid in the pollination of several flower species, thus benefiting the ecosystem. No, the butterflies could spread the pollen of the purple flowers to native plant species.

No, the butterflies may not have a natural predator in this environment; thus, they could displace native species that consume nectar

Explanation:

The escaped butterfly are considered an exotic species in their new environment. Exotic species in a new environment can establish themselves and sometimes outcompete or have selectional advantage over native species in that environment, eventually displacing the native species.

Hence, that some of the butterflies were allowed to escape into the environment is not environmentally safe for the native species in that environment.

the father in the first generation probably had the recessive colorblind trait in his x chromosome. if he and his wife both had the colorblind trait, even if she had 1 recessive and 1 dominant, then that trait would be passed on to their kids.

(since you didn't attach the family tree this is just an assumption)

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !
