Explanation:
A biochemical pathway (also called a metabolic pathway) is a series of enzyme-mediated reactions where the product of one reaction is used as the substrate in the next. Each enzymes is coded by a different gene. ... A mutation within a gene will often result in a non-functional enzyme.
True. A patient complaining of burning sensation and frequency of urination, otherwise known as dysuria, is a symptom associated with a urinary tract infection. Other associated symptoms such as fever and hematuria (blood in the urine) should be elicited as this will affect the assessment and plan of management for the patient. A urinalysis with a clean-catch specimen should be requested to confirm the diagnosis.
Answer:
1.Mitochondria is considered as the power house of the cell as it helps in producing large amount of energy in the form of ATP (adenosine triphosphate) that is used in driving various cellular activities.
2.Through a process called photosynthesis, plants use energy in sunlight to turn a gas called carbon dioxide and water into sugar. Plants then use this sugar to grow. At the same time, plants produce a gas called oxygen as a waste product, which is lucky for us and other animals because we need oxygen to breathe!
3.Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.
4.Cellular respiration uses oxygen and has it's waste product of carbon dioxide (CO2). How does photosynthesis demonstrate the law of conservation? ... The AMOUNT of carbon-dioxide atoms released by respiration are EXACTLY EQUAL to the atoms of these materials contained in the oxygen and carbon converted.The Law of Conservation of Matter states that matter cannot be created or destroyed. The carbon cycle is an example of the Law because the same carbon atoms are being recycled through the carbon cycle. ... Carbon is used for energy, and some is stored for growth.
Answer:
A person has the genotype of 9, 9 on one of his microsatellite loci.
An electrophoresis was conducted on the PCR products of this locus. Which lane on the gel below is most likely the result of the PCR fragments
Lane: A
Explanation:
DNA´s negative charge, given by phosphate groups is carried applying electrophoresis, on an agarose gel matrix, so that the equally-sized fragments put up at the same spot on the gel. After applying power, DNA fragments migrate to the positive electrode due to the enforced power, that way smaller fragments travelling faster, and larger fragments travellying slow, are size-sorted
We can see the gotten diagram for this person:
Column A as the most likely PCR fragments.
