Answer:
Plus end and kinesin.
Explanation:
Three important cytoskeleton components are microtubules, microfilaments and intermediate filaments. Microtubules are the polymer of tubulin and plays an important role in the movement of cell organelles and its structure.
Microtubules shows the process of polymerization and depolymerization at different ends. The plus end shows the polymerization and minus end shows the depolymerization process. The kinesin protein is required for the process of polymerization.
Thus, the correct answer is option (D).
Answer:
Electricity, gravity of earth and structure of atom provide evidence.
Explanation:
The investigation of electricity, gravity of earth and structure of atom helps the student to understand that without touching, one object apply force on another object. In electric current, we can see the property of magnetism due to which it attract and repel objects while in gravity of earth, the earth apply gravitational force to attract objects towards itself. in the structure of atom, proton present in the nucleus which attract the electron present in the shells.
Answer: The great molecular biologist and Nobel laureate Francois Jacob has stated that the human brain has a built-in need for order. From earliest times, human beings looked out and recognized cycles, repetitive patterns in nature—day following night, the seasons, tides, lunar cycles, plant succession, animal migration—that conferred the ability to predict their recurrence, and thus people acquired a semblance of understanding of and control over the cosmic forces impinging on their lives.

<span>Composition. (We use the crust-mantle-core terminology to describe differences in chemical composition in Earth's interior. We use the lithosphere- asthenosphere terminology to describe differences the physical state and behavior. Note that the boundaries between layers with different compositions do not occur at the same depths as the boundaries between layers with different physical properties. For example, there is a change in composition when passing from crust into mantle. But there is no change in physical state or behavior at this boundary- the uppermost part of the mantle behaves in the same way that the crust does because it is still far enough below its melting temperature to be a rigid, brittle solid. The transition to a softer, more pliable solid occurs further down within the mantle and this change in behavior occurs with no change in composition.)</span>
I think the answer your looking 4 is B
