<span>useful substances must be selectively reabsorbed
Filtration of blood by kidney only selected based on the molecule size. That means all small molecule will enter the kidney, doesn't matter whether it is toxic or useful.
But kidney has another mechanism such as reabsorption. In </span>reabsorption, some specific useful molecule(like glucose) will be absorbed back.
Answer:
Behavior genetics.
Explanation:
Genetics may be defined as a branch of biology that studies the inheritance and variation of the inherited characters. Mendel is known as the father of the genetics.
Behavior genetics may be defined as the field of the scientific research that uses the genetic methods to investigate the behavioral differences in the individual. This genetics uses the limits of genetics and environmental impact on the individual's behavior.
Thus, the answer is behavior genetics.
The student's conclusion was incorrect because the tropical rainforest biome has an average of 200-400 centimeters or 80-100 inches of rain a year. The correct biome based on the climatograph is temperate grassland because, on average per year, this biome has 25-75 centimeters of precipitation each year. Its temperature is ranging from 0-25 degrees Celcius.

I would assume it to be a fault - block mountain.
Hope This Helps You!
Good Luck :)

Answer:
In males primary spermatocytes undergo two meiotic divisions. First meiotic division give rise to two secondary spermatocytes and secondary meiotic division give rise to four spermatids from two spermatocytes.
Therefore a. from 100 primary spermatocytes 400 sperms will develop (100*4= 400)
.
b. From 100 secondary spermatocyteS 200 sperms will develop(100*2= 200).
c. Spermatids do not undergo any further division rather they undergo differentiation to form mature sperms. Therefore from 100 spermatids, 100 mature sperms will develop.
d. One primary oocyte gives rise to one secondary oocyte and one secondary oocyte give rise to one mature ova so only one mature ova will develop from 100 primary oocytes.
e. 100 ova will develop from 100 secondary oocytes.
f. Polar body do not develop into ova and degenerates after some time so no ova will develop from 100 polar bodies.
