During the metaphase, chromosomes are taken to the equatorial plane, were they randomly line up. Option B. Mitotic spindle attaches to the chromosome's centromeres and lines them up in the middle of the cell.
<h3>What is the metaphase?</h3>
Metaphase is one of the cell division stages that follows the prophase and precedes the anaphase.
During this phase, chromosomes are taken toward the center of the cell by the spindle apparatus. Once in the equatorial plane, chromosomes randomly line up.
Once aligned, each chromatid joins with a microtubule of opposites poles and gets ready to go through the anaphase. Sister chromatids are held together until they reach the Anaphase.
Since chromosomes in this stage are well defined and can be observed in detail under the microscope, they are used to create karyotypes and identify chromosomal abnormalities.
These chromosomes have the typical X shape.
Among the options, the one that correctly describes the metaphase is Option is B. Mitotic spindle attaches to the chromosome's centromeres and lines them up in the middle of the cell.

Answer:
D. A substance that is different from the reactants
Explanation:as it always result to compound
Answer;
Homozygotes increase in frequency in the population over generations. and genetic variation decreases in the section of the population.
Explanation;
-Inbreeding is the mating of relatives or, mating of individuals with at least one common ancestor. With continuous inbreeding, genetic variation is lost and homozygosity is increased, enabling the expression of recessive deleterious alleles in homozygotes.
-By inbreeding, individuals are further decreasing genetic variation by increasing homozygosity in the genomes of their offspring.
Answer:
Bleeding disorders can result from the lack of vitamin K
Explanation:
Vitamin K is a fat-soluble vitamin critical for proper blood clotting. Deficiency is associated with easy bleeding. Besides its role in blood coagulation, vitamin K is also important for healthy bones. Symptoms of deficiency include:
Nose bleeds Easy bruising,
Bleeding gums, Heavy menstrual bleeding
, and Blood in the urine.
