Gregor Mendel started experiments on inheritance in the 19. century. The basis of inheritance patterns is the fact that diploid cells contain two copies of the genome and that a gene has different variants, called alleles.Alleles can be dominant (for example, marked A) and recessive (for example, marked a). In a gene locus (position of a gene) there are only two alleles, one from the mother and the other from the father.If individuals have two copies of the same allele they are homozygous (AA (dominant homozygous) or aa (recessive homozygous)). If individuals have two different alleles they are heterozygous (Aa).In autosomal dominant traits, the phenotype is present if both copies of the dominant allele (A) are present (homozygous individuals AA) or only one copy of the dominant allele is present (heterozygous individuals Aa).In autosomal recessive traits, the phenotype is present if both copies of the recessive allele (a) are present (homozygous individuals aa).This is complicated in sex-linked trait, because there are two X cromosomes in females and one X chromosome and one Y chromosomes in males, so terms dominant and recessive are not reliable.It should also be taken into consideration that many traits are complex and caused by many genes interaction and/or environment conditions.
A <u>Scientific method </u>is a series of steps used to determine solutions based on needs and wants.
<h3>What is needs assessment?</h3>
A needs assessment is a process that bridges the gap between an organization's current state and the desired conditions. It is a systematic procedure for identifying and addressing performance gaps as well as repairing any defects that may occur in an organization.
<h3>What are the six steps of the scientific method?</h3>
- Describe the issue :Observation with intent
- research : learn more about the subject
- educated guess : hypothesis forecast the outcome of the problem
- experiment :Create a procedure for testing the hypothesis.
- analyze :Keep track of the experiment's outcomes.
- conclusion : compare the hypothesis to the results of the experiment
<h3>What are the Characteristic Features of Scientific Methods?</h3>
- Students learn to identify and formulate scientific problems correctly and in an organized manner using scientific methods.
- Students are trained in information processing techniques using scientific methods.
- Scientific methods help students develop the ability to think critically and rationally, allowing them to make decisions on logical and rational grounds.

It takes the food you eat, breaks it up into small pieces, and turns it into energy
Answer: a. NADH/FADH2
Explanation:
Complete oxidative degradation of glucose can be compartmentalized into four main biochemical steps: glycolysis, the formation of acetyl-CoA, the Krebs (citric acid or tricarboxylic acid cycle) and the electron transport chain where oxidative phosphorylation is performed. During respiration, an organic compound (usually sugar) is completely oxidized to form CO2 and H20. The Krebs cycle is the set of reactions leading to complete oxidation of glucose. It occurs in the mitochondria of eukaryotes and the cytoplasm of prokaryotes. Per each degraded glucose molecule, resulting in the final of the Krebs cycle:
• 6 molecules of NADH.
• 2 molecules of FADH2
• 2 molecules of ATP
• 4 molecules of CO2
Which gives our answer What is/are the major potential energy product(s) formed in the Krebs Cycle? a. NADH/FADH2 because 8 molecules of them in total are made.
