Answer:
estrogen
Explanation:
Birth control pills contain synthetic hormones which are naturally produced by females. These pills are used to prevent ovulation by maintaining a level hormone balance, so no egg is released. Combination pills contain estrogen and progestin, while progestin-only pills (also known as the minipill) don't contain estrogen. Progestins are synthetic hormones that act to mimic the naturally occurring hormone progesterone. Progestin-only pills are recommended in women who cannot take estrogen.
38 chromosomes
<span>The two identical daughter cells resulting from mitosis and cytokinesis are identical in the following ways:1. Mitosis occurs when the nucleus of the cell divides into two identical nuclei, each with the same type and number of chromosomes. The cell's DNA is duplicated during this phase. Sometimes the cell's DNA isn't copied properly resulting in cancer-type cells. 2. Cytokinesis is when the cytoplasm divides into two identical daughter cells. Each cell is genetically identical and both are a similar size. </span>

Planaria.
Explanation:
The kingdom eukarys is divided into the different phyla including almost all the animals. The organism are classified on the basis of their level organisation, cavity and on the basis of coelom.
The cephalization is initial process for the deposition of nervous tissue in brain. The cephalization is absent in porifera and coelenterate. The planaria also known as flat worms shows the process of cephalization and this process becomes more complex in higher animals.
Thus, the correct answer is option (4).
