VashaNatasha [74]

Answer:

Heart valve problems

Explanation:

Marfan syndrome is a syndrome caused by a genetic defect in a gene that is important to define the structure of a protein called fibrin 1 which makes a part of connective tissue.  

One of the main problems with people having this disorder is heart problems. Most of the people with Marfan syndrome have damaged aorta. Aorta plays an important role in carrying blood from the heart to other body parts. Therefore heart valve problem is the clinical finding that would be a treatment priority for this client.  

Other symptoms associated with these disorders are tall aperture, long and disproportionate arm and leg, abnormal spine structure, etc.

Assume that cells that are about to undergo meiosis are treated with a chemical that blocks crossing over but does not affect th
kupik [55]

Answer:

Crossing over is the phenomenon by which homologous chromosomes exchange DNA segments between them during the process of meiosis.

If crossing over did not occur, there will be no genetic variation among parents and offsprings.

If the process of meiosis did not occur, there will be lesser chances of genetic variations to occur. Each chromosome will be either from the father or the mother with no genetic diversity present in it. As a result,  genetic diversity will reduce.

How does the length of time the dinosaurs roamed the earth compare to the amount of time humans have existed on Earth?
Gnesinka [82]

Non-bird dinosaurs lived between about 245 and 66 million years ago, in a time known as the Mesozoic Era. This was many millions of years before the first modern humans, Homo sapiens, appeared.

In the Cori cycle, when glucose is degraded by glycolysis to lactate in muscle, the lactate is excreted into the blood and retur
saveliy_v [14]

Answer and explanation:

Glycolysis and gluconeogenesis are metabolic pathways of great importance in the regulation of glycemia (glucose levels in the blood).

While glycolysis, a catabolic pathway that occurs when the glucose levels are high and is used to generate energy inside our cells; gluconeogenesis, an anabolic pathway, happens because glucose levels aren't high enough for our tissues to perform their energy-demanding tasks.

Glycolysis is stimulated by <u>insulin</u> and transforms 1 glucose molecule into 2 pyruvate molecules, which can then be further metabolized to produce ATP. Gluconeogenesis does the opposite: being stimulated by <u>glucagon and epinephrine</u>, it converts pyruvate molecules into glucose molecules to elevate glycemia.

Partaking in antagonizing pathways, glycolysis and gluconeogenesis appear to be the exact reverse pathway for one another, except for a few specific enzymes that are unique to each one of them.

a. glyceraldehyde 3-phosphate dehydrogenase - both pathways. This enzyme catalyzes the conversion of glyceraldehyde 3-phosphate into 1, 2 biphosphoglycerate, and backward.

b. phosphofructokinase-1 - glycolysis. This kinase phosphorylates (adds a phosphate group) fructose 6-phosphate into fructose 1, 6 biphosphate. In gluconeogenesis, the opposite reaction occurs thanks to the fructose 1, 6 biphosphatase (which removes a phosphate group from fructose 1, 6 biphosphate).

c. phosphoenolpyruvate (PEP) carboxykinase - gluconeogenesis. In glycolysis, phosphoenolpyruvate is transformed to pyruvate in one single reaction, catalyzed by enzyme pyruvate kinase. But in gluconeogenesis, pyruvate needs first to be converted into oxalacetate by the pyruvate carboxylase, so can then be transformed into phosphoenolpyruvate by the PEP carboxykinase.

d. alcohol dehydrogenase - neither pathway. Alcohol dehydrogenase is an enzyme that can be found in Ethanol metabolism, catalyzing the forming of acetaldehyde from an ethanol molecule.
