<span>Vacuoles are organelles present in plant cells, some animal, and some prokaryotic cells. There is a difference in size between plant and animal cells. Plant cells usually have one large vacuole while animal cells have a number of small vacuoles. If the term "small vacuoles" is used for vacuoles in animal cells, then they are involved in overcoming the foreign particles, storage of waste and during the exocytosis, and invagination of the cell membrane during engulfing the bacteria.</span>

Answer:
The correct answer is C. Iodine directly helps the thyroid gland to function properly.
Explanation:
Iodine is essential for our thyroid hormones to function properly, and in turn, our body.
Thyroid hormones have vital functions such as regulating energy metabolism and nutrients such as proteins, carbohydrates and fats. They also affect tissue growth, especially the nervous; They also participate in the regulation of body temperature.
That is why the adequate supply of iodine contributes to the normal functioning of the thyroid, but if it is excessive it can cause health problems such as hyperthyroidism; and if its contribution is too low, it can cause hypothyroidism or even irreversible consequences if this deficit is severe or occurs, for example, in pregnancy, lactation or first year of life.
If a dihybrid F1 plant, self-fertilizes, the F2 progeny will have two types of phenotypes. One would be the dominant trait phenotype for both the alleles, which would be possessed by 3/4th of the population.
Other would be recessive trait phenotype for both the alleles, which would be possessed by 1/4th of the population.
One fourth of the population would be true-breeding for the dominant traits.
Half of the population would be heterozygous for both traits and would have dominant phenotype
Rest one-fourth population would be homozygous for both recessive traits
