Answer:
Option B, Apply auxin directly to the lower part of the stem opposite from the direction you want the stem to bend.
Explanation:
Options for the question are
A) Apply auxin directly to the shoot tip on the side to which you want the tip to bend.
B) Apply auxin directly to the lower part of the stem opposite from the direction you want the stem to bend.
C) Inject compounds that block auxin receptors into the part of the stem opposite from the direction you want the stem to bend.
D) Plant the roots in two different pots, and apply auxin to the root bucket that is on the same side as the direction you want the plant to bend.
Solution
Auxin is responsible for stem elongation by inhibiting growth of lateral buds. The movement of auxin is opposite to the direction of elongation of cells. Generally, Auxin moves to the dark side which is opposite to the direction i.e the lighter side in which cell elongate . Due to this growth pattern, the stem tip gets curved towards the light.
Hence, option B is correct
Answer:
A
Explanation:
We can't see the graph, but I think I found the worksheet online, and so the graph is attached.
The answer cannot be B, as we are looking at a graph of pH, not temperatures. Therefore, we cannot draw this conclusion
The answer cannot be C, as pepsin is a digestive enzyme, and it works best at pH of around 2.
The answer cannot be D, because we can see that arginase and salivary amylase work at pH 7 and above, which is not acidic
The answer is A, because the lines for each enzyme are different, each peaking at a different pH. These peaks represent their optimum temperatures, and the hills of the peak represent the range in which they can work
Dr. Pringle suggests that there's only very few large herbivorous species that can survive in certain area. The reason behind his claim is that according to him there will be only enough food for few large species, so there's natural limitations in the food sources, as there should be enough to support them in order for them to survive.
On the other hand, in Mpala, there's 22 large herbivorous species, which directly contradicts Dr. Pringle's hypothesis. The reason why so many large species of herbivores an survive in Mpala and always have enough food for all of them, is that they have all specialized in eating certain types of plants or parts of plants, thus they are not direct competition to one another, and there's always enough food for all of them.
Answer:
Microtubules have an inner diameter of 25 nm and an outer diameter of 30 nm.
Explanation:
Microtubules is a microscopic tubular structure that is present in the cytoplasm of cells; they are polymer structures that form part of the cytoskeleton that gives shape to cytoplasm of eukaryotic cells and some prokaryotic cells. A microtubules can be as long as 50 nm in diameter. The average inner diameter of microtubules is 25 nm while that of the outer diameter is 30 nm.
