The answer is <span>b.reaction b releases more energy than reaction a releases.
The reaction a is an example of a chemical reaction while the reaction b is an example of a nuclear reaction.
</span><span>Some main differences between the chemical and nuclear reactions are:
- The nuclear reaction releases more energy per gram.
- The nuclear reaction takes place in the nucleus of the atom, while in chemical reactions include electrons.
- In the nuclear reaction, part of the mass is converted into energy, which </span><span>violates the law of conservation of mass.
</span>
Therefore, the nuclear reaction (reaction b) will release more energy than the chemical reaction (reaction a).
Some plants have genetic modifications to tackle dry conditions and some plants in desert kind of atmosphere have specially adopted structures for effecting osmosis and diffusion.
Explanation:
- Osmosis help plants to absorb water from soil. Diffusion is the process by which carbon dioxide diffuses to the leaves and then to the cells.
- The genetic modifications in some of the plants can help in survive and adopt the osmosis in a very dry environment. They also develop defense methods to handle the water loss.
- Some plants in a permanent dry environment like desert have special structures like reduced leaves, hairs, sunken stomata, and so on to conserve water.
DNA condenses to form chromosomes, spindle fibers form, and the nuclear envelope disappears.
Centrosomes migrate to either pole, not chromosomes, and I couldn't find anything that said each chromosome pairs up with its mate.
Answer:
False.
