Answer:
Th acceptable distance of tubulin monomers along a protofilament is : <u>A. 4nm</u>
Explanation:
MICROTUBULES are an important component of the cytoskeleton of eukaryotic cells. Its function is part of a structural role that helps define cell morphology, and also serves as an intracellular motor for some proteins such as kinesin and dynein.
For the correct formation of the structures called microtubules to occur, a process called polymerization is required. In this process there is a head-to-tail junction in which the dimer junction between tubulines forms a structure called protofilaments and those protofilaments run along the microtubule. Then, the other process occurs in which, by lateral interactions between the structures mentioned above , the wall of The microtubule will be completed.
Answer:
Speed is directly proportional to position and inversely proportional to time.
Explanation:
Increase in speed means covering a larger distance in a small time
Answer:
1. Water
2. Carbon dioxide
3. Sunlight
4. Oxygen
5. Glucose
Explanation:
The above shows the correct answer. The labelled parts have been correctly named.
From the diagram, we can see that the water falls on the soil where it is absorbed by the roots. The leaves of the plant take in carbon dioxide as seen no. 2 and gives out oxygen as seen in no. 4. The plant also absorbs the sun energy. These are needed by the plant for photosynthesis which is a process that leads to the manufacture of glucose and energy.
A fire extinguisher, this is because it can burn your skin and it is meant to suffocate the flame and can suffocate you in the process. The best option for a human is a fire blanket.
The answer would be C.
The sample should represent the whole population not just a small part of the population.
