Answer:
The hemocytoblast (option B) are the parent cell for all formed elements of blood
Explanation:
All blood cells are originated from a common stem cell, which is called a pluripotent stem cell. It is capable of giving rise to any of the blood cells maintaining its existence through mitosis. By dividing pluripotent stem cells, new cells are originated, which become multipotent and differentiate into lymphoid (NK cell and the polymorphonuclear cell) or myeloid cells (megakaryocite); always respecting the original quantity.
The next eclipse in the Saros cycle will be at 22nd of August 2017.
<h3>What is an eclipse?</h3>
Eclipse is an astronomical phenomenon marked by the total or partial darkening of a star due to the passage of some celestial body in front of a light source. There are two categories of eclipse: the solar eclipse and the lunar eclipse.
With that being said it is possible to notice that all eclipses are happening with an interval of 18 years. So as the last eclipse was in 1999, the next one will be in 2017. As for the day, it is possible to notice that they are happening 11 days after the last one. So as the last one was in 11th of August, the next one will be in 22nd of August.

Answer:
A. The urinary tract infections or the UTI refers to the infections found in the urethra, kidney, and bladder. The infection generally takes place because of the entry of bacteria that may invade the urethra or bladder. This leads to irritation in the bladder primarily in women.
B. In urinary tract infections, primarily the kidneys, bladder, and ureter get affected. The infection is most commonly caused by E.coli and Klebsiella species. In women, the urethra is generally shorter in comparison to males, thus, bacteria can easily invade the bladder most probably at the time of sex.
The mentioned bacteria are usually found in the digestive tract and may move into the urinary system, mainly at the time of sexual intercourse.
Genetic diversity occurs through natural selection and the process of natural selection is a evolutionary process which occurs with time and ages through the generations.
While genetic variation is caused by mutation, random fertilization and recombination. This usually occurs during cell division and reproduction or any infection.
Thus Genetic diversity is a long process while the genetic variation is an immediate process of producing variation in the genes.
