If a scientists data was contaminated what is the best course of action

Biology

Varvara68 [4.7K]3 years ago
3 0

Answer:

  • Of course, the best course of action is to <u>re-analyze</u> the samples again and generate a new dataset. This would be time consuming and may require further cost. But this would be the best possibility to eliminate bias from the data.
  • In case, if re-analysis is not possible, then another option is to see the standard deviation among replicate. If only one replicate is contaminated, and other two are fine, then we can simply remove the contaminated sample considering it as an outlier.

What stage is the glucose molecule formed
anyanavicka [17]

Answer:

  1. GLYCOLYSIS :- Glycolysis is the metabolic pathway that converts glucose C₆H₁₂O₆, into pyruvic acid, CH₃COCOOH. The free energy released in this process is used to form the high-energy molecules adenosine triphosphate and reduced nicotinamide adenine dinucleotide
  2. PRODUCTS :- Glycolysis produces 2 ATP, 2 NADH, and 2 pyruvate molecules: Glycolysis, or the aerobic catabolic breakdown of glucose, produces energy in the form of ATP, NADH, and pyruvate, which itself enters the citric acid cycle to produce more energy.
  3. INPUT:- Glycolysis is the first step in cellular respiration, occurring in all living cells. Overall, the input for glycolysis is one glucose, two ATP and two NAD+ molecules giving rise to two pyruvate molecules, four ATP and two NADH.
  4. BREAKDOWN:- During glycolysis, glucose ultimately breaks down into pyruvate and energy; a total of 2 ATP is derived in the process (Glucose + 2 NAD+ + 2 ADP + 2 Pi --> 2 Pyruvate + 2 NADH + 2 H+ + 2 ATP + 2 H2O). The hydroxyl groups allow for phosphorylation. The specific form of glucose used in glycolysis is glucose 6-phosphate
  5. STAGES:-
  • Reaction 1: glucose phosphorylation to glucose 6-phosphate.
  • Reaction 2: isomerization of glucose 6-phosphate to fructose 6-phosphate
  • Reaction 3: phosphorylation of fructose 6-phosphate to fructose 1,6-bisphosphate
  • Reaction 4: cleavage of fructose 1,6-bisphosphate into two three-carbon fragments.

The population in South Africa is more prone to sickle cell anemia (genotype "ss"). People with genotype "ss" survive only up to
lions [1.4K]
The answer is stabilizing selection.

<span>Sickle-cell anemia is a recessive disorder caused by the presence of two recessive alleles "s", so genotype is "ss". This disorder is characterized by sickle hemoglobin. In an area with malaria, heterozygous individuals "Ss" (with one dominant allele and one recessive allele) have an advantage. These individuals will have both normal and sickle hemoglobin. But pathogen that causes malaria affect only normal hemoglobin, so heterozygous individuals will have half of the hemoglobin resistant to the pathogen and those individuals are resistant to malaria.</span>

Stabilizing selection favors heterozygotes Ss,  disruptive selection favors dominant (SS) and recessive (ss) homozygotes, while directional selection favors dominant (SS) or recessive (ss) homozygote. Since in this example, people with genotype Ss (heterozygotes) are in advantage, then this is an example of stabilizing selection.
