Answer:
Connect the centromere to microtubules. (Option A)
Explanation:
The kinetochore is known as the complex of protein which is disc shape in structure. The structure of kinetochore is divided into three parts: inner region, outer region, and fibrous corona. Each part of the kinetochore works in its own way in the separation of the sister chromatids.
During the process of cell division (mitosis, and meiosis) kinetochore collects on the centromere and allows the chromosome to link with microtubules.
The mass of a star can be determined by studying D) binary star systems.
Although there may be other ways to determine the mass of a star, this is the most common one which is widely used all over the world when it comes to measuring objects in the universe.

Proteins function optimally at a specific temperature. So if you get too hot or too cold, biochemical reactions in your body start to function less well. If the situation becomes extreme enough, they can cease to function well enough to sustain life.
Warm-blooded animals have an advantage over cold-blooded ones in that their bodies automatically try to maintain the optimal termperature for things in their bodies to function. Cold-blooded animals depend on the environmental temperature to do this for them. That's why reptiles are very sluggish when they're cold, but will "wake up" when they get warm.
The cost to this benefit is that metabolically, warm-blooded animals require a lot more fuel to run their bodies. It's very energy-intensive to maintain a constant body temperature. Cold-blooded animals require far less fuel than warm-blooded ones relative to their size.
The way that proteins operate in a specific temperature is also true of the pH in your body which is also very tightly maintained.
