They all share at least 50% of the same DNA arrangement. It is correct because i just took the quiz and answered like 1 minute and 26 seconds ago.

Answer:

The correct answer is "They all share at least 50% of the same DNA arrangement".

Explanation:

DNA analysis have allowed to establish phylogenetic trees with reliable information about the evolutionary relationship that species have. In this example Animal A and Animal B share 95% of their DNA sequences, while Animal A and Animal C share 50%. Even though Animal B and Animal C relationship is not established, it is sure to state that all animals share at least 50% of the same DNA arrangement since Animal A and Animal B are almost identical. This support the idea that life changed over time, where it is likely that all animals share a common ancestor that eventually diverged in the three animals at which Animal C is the most divergent.

Rzqust [24]

Answer: The progeny of this cross do not conform to a 1:1:1:1 ratio

Explanation: This is because out of the 200 total resulting progeny, we must have 50 in each phenotype class to conform with the 1:1:1:1 which is not so as we have 48 in one of the phenotypic class already. Therefore, it did not conform to the ratio.

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.

Feliz [49]

Transport of a substance from the lumen (cavity) of an organ into one side of a cell and out the other side of the cell into the extracellular fluid is called <u>transcellular transport</u>.

The two routes of transport of substances across the epithelium of the gut are by transcellular method and paracellular method.

Transcellular transport refers to the transport of solutes across a epithelial cell layer through the cells.  The best example is the movement of glucose from the intestinal lumen to the extracellular fluid by the epithelial cells. The epithelial cells use the active transport to generate the transcellular transport. Active transport refers to the transport of substances from a region of its lower concentration to a region of its higher concentration against the concentration gradient using cellular energy.
