Excretion and the Kidneys The kidneys remove excess water, minerals, and other waste products from the blood. The cleansed blood returns to circulation. Each kidney has nearly a million processing units called nephrons. Filtration and reabsorption occur in the nephrons.
- Filtration is the passage of a fluid or gas through a filter to remove wastes. The filtration of blood in the nephron takes place in the glomerulus, a small, dense network of capillaries. Each glomerulus is encased by a cuplike structure called Bowman's capsule. Pressure in the capillaries forces fluids and wastes from the blood into Bowman's capsule. This fluid is called filtrate.
- Most of the material that enters Bowman's capsule is returned to circulation. The process by which water and dissolved substances are taken back into the blood is called reabsorption.
- A section of the nephron tubule, called the loop of Henle, conserves water and minimizes the volume of filtrate. The fluid that remains in the tubule is called urine.

Each kidney has nearly a million individual processing units called capillaries is false as the units are called nephrons.
What are the nephrons?
Nephron, processing unit of the kidney, the shape that certainly produces urine withinside the procedure of doing away with waste and extra materials from the blood.
The nephrons paintings via a two-step procedure: the glomerulus filters your blood, and the tubule returns wanted materials for your blood and eliminates wastes. Each nephron has a glomerulus to clear out out your blood and a tubule that returns wanted materials for your blood and pulls out extra wastes.

A genius IQ is considered anything over 144. Let's pretend that
this is a genetic condition and that it is recessive. Genius IQ
is found in approximately 1 in 625 people worldwide (this is a
true statistic). Calculate the following:
1. The frequency of the recessive allele (genius IQ).
2. The frequency of the dominant allele (normal).
3. The percentage of heterozygous individuals (carriers).
According to the question, The percentage of heterozygous individuals (carriers). Thus, option "C" is correct.
What is the Hardy-Weinberg equilibrium theory?The Hardy-Weinberg equilibrium theory states that the allelic frequencies in a locus are represented as p and q. Assuming a diallelic gene,
p is the frequency of the dominant allele,
q is the frequency of the recessive allele.
The genotypic frequencies after one generation are
p² (H0m0zyg0us dominant genotypic frequency),
2pq (Heter0zyg0us genotypic frequency),
q² (H0m0zyg0us recessive genotypic frequency)
Thus, option "C" is correct.

state the difference between the synthesis and the breakdown of a protein. thanks!
Synthesis of protein is the building up of protein molecule while the breakdown of protein is the degradation of the protein molecule.
What is protein?Protein is one of the biological molecules that present in living organisms and contain it's building blocks known as amino acids.
The synthesis of protein is the process used by living organism to produce proteins from amino acids (that is the building block).
The breakdown of protein is the degradation of protein molecule which is also called catabolism.
Therefore, the difference between protein synthesis and breakdown is that synthesis of protein is the building up of protein molecule while the breakdown of protein is the degradation of the protein molecule.

If you were to place blood tissue in a hierarchical pyramid, the hierarchical levels would be directly Above: cardiovascular system, Below: heart
What is the cardiovascular system?The cardiovascular system is made up of the heart and blood vessels. The heart works like a pump, allowing blood to be pumped. Arteries are blood vessels that carry blood from the heart to the body. Veins are blood vessels that ensure the return of blood to the heart.
With this information, we can conclude that if you were to place blood tissue in a hierarchical pyramid, the hierarchical levels would be directly Above: cardiovascular system, Below: heart

23. An unknown solution is colorless when tested with phenolphthalein but causes the indicator phenol red to turn red. Use this information to find the approximate pH of this solution.
Phenolphthalein is a weak acid and is colorless in solution. It is generally used to find out the endpoint of titration. As the An unknown solution is colorless when tested with phenolphthalein but causes the indicator phenol red to turn red it indicates the pH of the solution is 8.0 or above.
What is phenol red?Phenol red is an indicator whose color can exhibit a gradual transition from color yellow to red.
Phenol red is actually a water-soluble dye as is used as a pH indicator, changing from yellow to red over pH 6.6 to 8.0.
Thus, it can be concluded that the pH of the given unknown solution is in range 8.0 or above.
