Answer:
Colchicine inhibits the formation of microtubules by inhibiting tubulin, a protein required for microtubule synthesis. Microtubules in the form of spindle fibers during cell division pull the DNA from the center of the mother cell into the new daughter cells. If microtubules are not formed DNA will not move into new cells. Hence new cell formation will be inhibited in the metaphase stage. Thus the correct answer is option D.

Answer:
Photosynthetic lamellae
Explanation:
The cyanobacteria were the first successful photosynthetic cells present on the Earth which were able to convert the light energy into the chemical energy.
The endosymbiosis theory suggested that these cyanobacteria were engulfed by the eukaryotes and the cyanobacteria get transformed into the chloroplast.
The region of the chloroplast that was formed in the cyanobacteria before the endosymbiosis happened was the photosynthetic lamellae which contained the chlorophyll molecule and thus is the correct answer.
Thus, Photosynthetic lamellae are the correct answer.

Anaerobic respiration
The nurse should include the
following instructions while performing preoperative teaching for an older
adult client who will be undergoing surgery to remove a cataract removed:
1. “A cataract is an opacity of
the lens, which may be as a result of aging, sunlight, or trauma.”
2. “A number of different types
of eye drops would have to be taken several times a day for up to 4 weeks after
the surgery.”
3. “A medication will be administered
to help you relax. You will also receive some different eye drops to dilate
your pupils and paralyze the lens."
4. "You are required to bring
sunglasses with you on the day of your surgery."
5. "Please, may I request you to show me how to put these natural tear
drops in your eyes?"
Answer:
In a particular case of secondary succession, three species of wild grass all invaded a field. By the second season, a single species dominated the field and the other two species had a lower relative abundance. A possible factor contributing to the abundances of these species in this example of secondary succession is <u>inhibition</u>.
Explanation:
Trees are great examples of allelopathy in plants. Some use their allelochemicals to inhibit germination or impede development of nearby plant life. Most allelopathic trees release these chemicals through their leaves, which are toxic once absorbed by other plants. Black walnut is a prime example of this.
