name two components of blood that are not present in glomerular filtrate
Answer:
Filterable blood components include water, nitrogenous waste, and nutrients that will be transferred into the glomerulus to form the glomerular filtrate. Non-filterable blood components include blood cells, albumins, and platelets, that will leave the glomerulus through the efferent arteriole.
:_:
Blood cells and plasma proteins are the two components that are not present in glomerular filtrate.
What is blood cells?"A blood cell is a cell produced through hematopoiesis and found mainly in the blood."It includes RBCs, WBCs and platelets.What are plasma proteins?"Plasma proteins are proteins present in blood plasma."It plays an important role in immune system.What is glomerular filtrate?The filtrate formed after filtration of blood in the glomerulus is called glomerular filtrate. It consists majorly of water and other constituents such as amino acids, glucose, potassium, sodium, urea, uric acid and ketone bodies.The filtrate does not contain RBCs, WBCs, platelets and plasma proteins.

Which of the following would increase the rate of an enzyme-catalyzed reaction? *25 points!!!*
a) Increase the concentration of inhibitors present in the reaction.
b) Decrease the concentration of cofactors present in the reaction.
c) Increase the substrate concentration and increase the enzyme concentration.
d) Decrease the substrate concentration and decrease the enzyme concentration.
Answer:
c) Increase the substrate concentration and increase the enzyme concentration.
An increase in substrate concentration favors to an increase in the rate of an enzyme catalyzed reaction. Thus, the correct option is C.
What are enzymes?The enzymes is defined as the protein which act as biological catalyst and speeds up the rate of a specific chemical reaction in the cell. The enzyme is not destroyed during the reaction and is used over and over.
As the enzyme molecules become saturated with substrate, this leads to increase in reaction rate levels off. As soon as the catalytic site is empty, more substrate is available to bind and undergo reaction.

The statement "they have sharp peaks" is a feature supports his conclusion that the Rockies were relatively young mountains.
What is a mountain?A mountain is an elevated area of the crust of the Earth, typically with steep sides that reveal a substantial amount of bedrock that has been exposed. Although definitions vary, a mountain is often taller than a hill, rising normally at least 300 meters above the surrounding terrain, and differs from a plateau in having a constrained peak area.
it is a landform that rises significantly above the surrounding terrain. Mountains, which are steeper than hills, are created when the Earth's crust's tectonic plates collide and push the land upward where they do. As an alternative, molten rock that has broken through the Earth's surface can also rise up and form mountains.

O A. Organic extraction
OB. EDTA extraction
OC. Chelex extraction
O D. Phenol-chloroform extraction
Answer:
The correct answer is - C. Chelex extraction.
Explanation:
Chelex extraction is a DNA extraction method that involves a Chelex100 chelating resin that prevents DNA degradation by traping the degradative enzymes and from potential contaminants.
In absence of this Chelex resin, a styrene polymer resin that binds metal ions that might inhibit downstream analyses. This process involves a commercially used Chelex 100 which is a styrene-divinylbenzene copolymer that has paired iminodiacetate ions, which act as chelating groups in binds metal ions.

Explain the reason the Type AB and Type O blood phenotypes always have the same
genotype, whereas the Type A and Type B blood phenotypes have two possible allelic
combinations.
Answer:
Because A is co-dominant to B and O is recessive, so the genotype is the same as the phenotype. But A can have 2 genotypes because A can mask a recessive allele, which makes the phenotype A. B can also mask a recessive allele, which makes the phenotype B.
Examples
AO (genotype) = A (phenotype)
BO (genotype) = B (phenotype)
