Answer no 1:
A pedigree can be described as a chart or a diagram which illustrates the patterns of inheritance among generations of a family. Family history is very important to know the genetic history of a disease and how it runs in a family. A pedigree will let know that what are the probabilities of a disease to occur in the offsprings based on the genetic history.
Answer no 2:
A punnet square can be described as a diagram which predicts the result of a cross. A genetic cross will let scientists know about the genotype and phenotype of the offsprings that will be produced. It will let us know about carriers as well probability of a disease to occur in offsprings.
Answer:
Eukaryotic cells make energy-rich molecules such as ATP and NADH through energy pathways including photosynthesis, glycolysis, the citric acid cycle, and oxidative phosphorylation, beginning with energy sources obtained from their environment in the form of sunlight and organic food molecules.
Explanation:
The <span>Crohn’s disease can be an example of a disease associated with the digestive system.
The </span>Crohn’s disease is a chronic inflammation<span> of the </span><span>gastrointestinal tract. Although it can be developed in any part of the gastrointestinal tract it is mostly aggressive ate the end of the small intestine to the passage to large intestine. It affects equally men and women and it starts usually between the ages of 15-35 years of age. It may appear because of genetic factors, environment, and simply an overactive inflammatory system.
It usually presents abdominal pain, rectal bleeding, frequent diarrhea, loss of appetite, weight-loss, and fatigue.
It is usually tested by blood tests to identify eventual </span>deficiencies of vitamins or minerals, and other indicators of anemia or inflammation. Also fecal blood tests to identify if the problem could be a result of some kind of infection rather then Crohn's disease. Other tests may include X-rays, CT scans,or MRIs, leukocyte scintigraphy, e<span>ndoscopy, and colonoscopy.</span>
