Answer: During metaphase, the cell's chromosomes align themselves in the middle of the cell through a type of cellular "tug of war." The chromosomes, which have been replicated and remain joined at a central point called the centromere, are called sister chromatids.

Answer:
Muscle spindles
Explanation:
Muscle spindles are stretch receptors thst has both the sensory abd motor components ĺocated in the body of a muscle that basically signals on alterations in the muscle length. They transfer the length information to the central nervous system through the afferent nerve fibers. It fasten the motor neurons through the stretch reflex to prevent muscle stretch. Muscle spindles are sensory receptors that are majorly found in the muscle.

Called solar system because Sun is biggest and heaviest
Solar means sun planets revolve about (travel in circles around) the sun path a planet travels is called its orbit earth is the 3rd closest planet to the sun all the planets go around in the same direction (like clockwise or counterclockwise), in roughly the same plane, but at different speeds planets close to sun move fast, far out move slower closer a planet is to the sun, the hotter it is, more or less.
The above is only approximately correct scientifically, but could be good enough for grade school. Look up "solar system" in wikipedia for more details and accuracy.

Answer:
Meiosis is important because during sexual reproduction, it ensures that all produced organisms have the correct number of chromosomes. It is also responsible for producing genetic variations during the process of recombination, and it repairs some genetic defects.
The disadvantage from not having the trait normally arises only after the reproductive stage of the individual's lifecycle is mostly over. This is a special case of "no strong pressure", because evolution selects genes, not the organism. In other words the beneficial mutation does not alter the reproductive fitness.

Isn't this Chem?
a non metal and a metal
a metal transfers electrons to the non metal
the non metal gains electrons and becomes an anion (a negatively charges ion)
and the metal loses electrons and becomes a cation (a positively charged ion)
