<span>This process is called the mitotic spindle
which begins to develop during the prophase. The reason why chromosomes must
line up on the cell equator before cell division is “<span>to enable the microtubules to attach to the
kinetochores properly”. The microtubules then form the network that will
later pull the duplicated chromosomes separately.
Answer: </span></span>to enable the microtubules to attach to the kinetochores properly
Non polar molecule move across a membrane through simple diffusion, when moving up their concentration gradient. Simple diffusion involves movement of molecules through a membrane without the help of integral membrane protein. These molecules are driven by the force of diffusion. This is different from facilitated diffusion where molecules only move with the aid of integral protein in the membrane.
The main function of carbohydrates is:
B. <u>Storing energy</u>
Answer: Electron Microscope is most appriopriate for studying living cells.
Explanation:
Most of the cells are so tiny that they cannot be viewed with the naked eye. Therefore, scientists must use microscopes to study the behavior of cells. Electron microscopes provide higher magnification, higher resolution, and more detail than light microscopes.
The major demerits are size, maintenance, cost, researcher training and image artifacts resulting from specimen preparation. This type of microscope is a large, cumbersome, expensive piece of equipment, strongly sensitive to vibration and external magnetic fields.
