<span>Cilia, flagella, and centrioles. Cilia and flagella are projections from the outside of the cell. They are made up of microtubules and are covered by an extension of the plasma membrane. They are motile, meaning that they are mobile, and designed either to move the cell itself or to move substances over or around the cell.</span>
Endorphins sound correct.

Alfred Wegener suggested the Continental Drift Theory.
However, this idea was dismissed by scientists. Continental Drift Theory states
that all continents were once joined together then they drifted away from each
other. It was backed by maps which showed that if continents were pulled close
together would fit each other perfectly, just like in a puzzle. However
scientists from different fields resisted the idea and accused Wegener of not being an expert of science. The strongest reason of the
rejection, however, was that Wegener could not explain how continental drift
happened.
Answer:
A type of cell division that results in two cells having the same number of chromosomes as the parent nucleus.
Explanation:
Typical for ordinary tissue growth.
Answer: They would be better able to survive in dry environment like deserts than animals with shorter loops.
Explanation:
The kidney is an organ found in animal that is used for the excretion of unwanted nitrogenous substances such as urea and other ammonium compounds from the blood. They also maintain the osmotic pressure of the blood by controlling the excretion of water and salts.
The urinary tubule is the functional unit of the kidney. This tubule is made up of:
--> Bowman's capsule
--> proximal convoluted tubule
--> loop of Henle
--> distal convoluted tubule and
--> collecting ducts.
The ability of the kidney to form a urine that is more concentrated than plasma is essential for survival of mammals that live on land including humans. When there is short supply of water, desert environment, the kidney forms a concentrated urine by continuing to excrete solutes while increasing water reabsorption and decreasing the volume of urine formed. The requirements for excreting a concentrated urine depends on the anatomical arrangement of the loop of Henle. A LONGER loop of Henle provides more osmotic gradient necessary for water reabsorption to occur than a shorter one there by limiting the need for water intake.
