The correct answers are B & C. Silicon-32 is the parent isotope, which decays into phosphorus-32 (daughter isotope). The silicon-32 amount is halved every 170 years, so we can use this to determine how old the rock is. The amount of phosphorus-32 increases over time, but it is not equal to the amount of silicon-32.
Sorrowful mood is described a sad feeling, especially when it involves grief or loss. For example- the loss of a thing one loves the most, the loss of a loved family member etc.
So, here in these lines of the poetry, the last line describes the sorrowful mood of the poet.

Answer:
c. Physical adaptations to the environment drive the distribution of all three species in the wild.
Explanation:
Options A and B refer to competition between species. The experiment was about the colonizing ability of the three species, and not the interaction among them. So these two options are not correct.
Option D states that species A is better adapted to the upper intertidal zone than the middle or lower. But the table shows that species A is equally adapted to colonize upper and middle intertidal zone, and less adapted to colonize lower zones.
The correct option is C. When these competing species coexist, this is because of niche partitioning or niche differentiation. If there is not any differentiation between them, the dominant species displaces the weak species. In the exposed example, the three species coexist in the middle and lower zones, which means that they probably have different niches and got adapted to living to their environments. This adaptation to different conditions is what leads to their distribution.
In the exposed example, species A and B can live in the upper intertidal zone, where species C can not live because they can not tolerate environmental conditions. The three species can live in the middle zone, but still, A and B are more adapted to this area than C. Among A and B, B is the most adapted to living in the upper and middle zones. Species C seems to be very adapted to live in the lower intertidal zone, where species A and B can also live, but are less adapted to this area, probably due to environmental conditions or due to their vulnerability to predation. In this last area, species A is less adapted.
The correct answer to this question is letter " a. metaphor." <span>Your words are bees about a pear-tree. From that statement, it is comparing words to the bees without the use of any keywords like "like and as ... as." So this is definitely a metaphor, not a simile.</span>
Answer:
(Indian Leaf Butterfly) CAMOUFLAGED
(Monarch Butterfly) CHEMICAL DEFENSE and COLOURFUL WARNING SIGNALS
Explanation:
The Indian leaf butterflies survives by camouflaging to deceive a potential enemy. They could also seek survival by blending to their presents environment such that a supposed enemy finds it hard to identify with their presence.
The monarch Butterfly are very colourful and are super in defending themselves through chemical means.
By chemical defense, they do well to feed on milkweed which is highly poisonous but they have their way of isolating themselves from the consumed poison.
They also send away predators using their colourful warning signals and bright colours. This colours informs predators that they contain poisonous contents.
When a predator bites a monarch Butterfly, it taste the poisons in the wings of the butterfly and let it go. But if peradventure a birds swallows a monarch, the experience of the taste of the poisons teaches the bird never to hunt a monarch Butterfly again
