Answer: a. Excesses are eliminated from the kidneys.
Explanation:
A fat-soluble vitamin can be dissolved in fats and oils. They are absorbed along with fats in the diet from the intestinal lumen using the same mechanisms used for absorption of lipids. Upon absorption, <u>these vitamins enter the lymph vessels</u> before making they go into the bloodstream. In most cases, fat-soluble vitamins must be coupled with a protein in order to be transported through the organism. <u>This means they are solubilized and transported by carrier proteins </u>to exert their actions.
By last, since fat-soluble vitamins can not be dissolved in water,<u> they are not readily excreted. So they can accumulate in fatty tissues</u> to toxic levels if taken in excess.

Answer:
b. Replicated chromosomes line up on the equatorial plate.
Explanation:
Mitosis starts with the breakdown of the nuclear envelop and condensation of chromatids into visible chromosomes. Since DNA replication has occurred during the S-phase of interphase, each chromosome has two sister chromatids held together by a centromere. A chromosome with two sister chromatids is said to be a replicated chromosome.
Metaphase of mitosis includes the alignment of replicated chromosomes at the cell's equator. The process is assisted by the spindle apparatus. This is followed by splitting of centromere and separation of sister chromatids during anaphase.
