Answer:
In meiosis I there is prophase I, metaphase I, anaphase I, and telophase I and then in meiosis II there is prophase II, metaphase II, anaphase II, and telophase II.
Explanation:
In meiosis I we have;
Prophase I in which a pair of homologous chromosomes line up and form a tetrad. This is the stage during which genetic recombination occurs.
Metaphase I occurs, during which the homologous chromosomes line up opposite each other at the metaphase plate. The chromosomes orientate themselves randomly, thus homologous chromosomes are distributed randomly to daughter cells .
In Anaphase I, homologous chromosomes move to opposite sides of the cells but sister chromatids remain together. Each cell now has 23 chromosomes.
Telophase I in which the homologous chromosomes move to the poles and cytokinesis occurs. Two daughter cells are formed.
In meiosis II we have;
Prophase II (note: there is no interphase as seen in mitosis) during which chromosomes start to move to the metaphase II plate. There is no replication.
Next is metaphase II when the chromosomes align at the metaphase II plate.
In anaphase II the sister chromatids separate from each other and move towards opposite poles.
Lastly, in telophase II cytokinesis occurs again and four daughter cells are produced. Each of the four daughter cells has 23 chromosomes.
Answer:
The correct answer to the following question will be "Mihrab".
Explanation:
- A semicircular niche throughout the wall of a mosque showing the qibla; that is, the direction of the Kaaba in Mecca, and hence the way that Muslims will face while they pray. Thus the wall into which a mihrab appears was the "qibla wall."
- A chanter calling for people to pray. Fana is a religious figure; in fact, a few of Muhammad's hereditary predecessors, worshiped in Shiite Islam.
- It is traditional, when entering a mosque, to remove somebody's shoes and put them on the entrance rack. This is accomplished out of respect and also to avoid soiling the interior floor of the prayer hall — prayer halls do not have chairs or benches, just row after row of carpets, aligned to face the holy sites of Mecca in Arabia.

The correct answer is 50.
Proteins are complex biomolecules made out of amino-acids bound together with peptide bonds. They can be comprised out of thousands of several polypeptide chains with thousands of amino-acids organised in complex structures. But, some of them can contain only around 50 amino-acid and still posses all of the complex traits of an protein.
Some polypeptides contain only 3 amino-acids, but technically they are not classified as proteins due to a big functional and structural differences between a simple polypeptide chain and a protein. Proteins are made out polypeptide chains, but this is only the primary structure of an protein. the polypeptide chains in a protein are organized into complex 3D structures that give them novel traits and complexity as compared to plain polypeptide chains.
