Answer:
AA
Explanation:
A true breeding organism for a particular trait is an organism that would produce progeny with the same trait whe self fertilized.
Hence, since axial flower is represented by the allele A, a true breeding flowering plant will have the genotype AA.
Axial flower (A) is dominant over terminal flower (a).
True-breeding axial flowering plant will have the genotype AA.
True breeding terminal flowering plant will have the genotype aa.
AA is crossed with aa.
AA x aa
offspring: Aa, Aa, Aa and Aa.
All the offspring will exhibit axial flowering.
Answer:
Taxol induces the assembly of microtubules, while Nocodazole suppresses tubulin assembly
Explanation:
Taxol and nocodazole are antimitotic drugs, i.e., drugs that inhibit the progression through the cell cycle, which is useful for killing cancer cells. Microtubules are proteins that act as the 'skeleton of the cell', which need to be reorganized when cells replicate. These structures (microtubules) are composed of α and β-tubulin heterodimers which assemble into protofilaments of microtubules. Taxol is an antimitotic drug that induces the formation of microtubules, thereby inhibiting microtubules' reorganization during mitosis. In consequence, cells treated with Taxol enter into apoptosis (i.e., programmed cell death). Moreover, Nocodazole is known to induce microtubule disassembly by interfering with the polymerization of tubulin monomers. In consequence, Nocodazole is useful to depolymerize the microtubule cytoskeleton.
Answer: Swim bladders of fish at depth help maintain buoyancy by regulating gas levels.
The plants absorb light energy into chemical energy. This energy is used by the plant for fuel. The byproduct of photosynthesis is Oxygen. That is why plants are so beneficial for air quality
The best question for this experiment is How does the composition of the soil affect the pH of the rainwater?.
<h3>What are the best factors being studied?</h3>
The main factors based on the description are:
- The pH of the rainwater: This is the factor manipulated by the researcher.
- The aluminum concentration: This is the factor researchers are evaluating.
<h3>What is the best question?</h3>
The best question would be one that relates the main two factors. Based on this, the best question would be: "How does the composition of the soil affect the pH of the rainwater?".
