<span>As the pollen tube penetrates the ovule, it releases two sperm cells. As in gymnosperms, the ovule becomes a seed, encasing the embryo and endosperm in a seed coat. But unlike gymnosperms, in angiosperms the ovary containing the ovules develops into a fruit after fertilization.</span>
Hello. You forgot to mention that this question is about the poem "Icarus's Flight". it is necessary that you always provide all the necessary information for your question to be answered as you deserve.
Answer:
The poem states that Icarus did the right thing because he used his skills to try to achieve his desire, instead of just wondering if "would it have worked?"
Explanation:
In short, we can say that the poem states that Icarus did the right thing, because he allowed himself to try. He had a desire, which he knew was risky, but he preferred to use his skills, rather than just theorizing about what might or might not happen. Icarus had a desire and he challenged himself and went after it, instead of just whining and questioning.
The poem shows, in the eighteenth line, that even in the face of possible failure, Icarus' experience would allow him to know himself better, knowing his weaknesses and strengths.
Answer:
C
Explanation:
When plant cells take in water, the vacuole swells. A swollen vacuole indicates the plant cell has all the water it needs. This suggests that the plant is taking in water and is maintaining optimum conditions. This is an example of homeostasis.
If the cells burst apart, as in A and E, this would suggest the cell is not properly maintaining homeostasis, as the cell bursting suggests something has gone badly wrong. This suggests the cell has taken in too much water; the cell has not been able to maintain homeostasis and regulate water uptake to prevent this from happening.
In the reverse case, where the cells shrink apart (as in B), the cell would also not be properly maintaining homeostasis by failing to bring enough water into the cell to maintain a turgid state. This is also damaging for the cells.
Finally, D and E can also not be correct, because water can cross the cell membrane, and does not need to be pumped in or sent out by endocytosis.
The answer is D. Food Threshold is the amount of food capable on feeding the organisms.
Important factor defining the desert biomes is its tendency to lose water by evaporation, and this potential for water loss exceeds the annual rainfall and defines what organism can live in there.
