According to my 9th grade biology knowledge,
The answer to this question is A: They have a recent common ancestor.
The classification of the characteristics and examples based on the model of speciation that is being described are as follows:
- <u>Allopatric Speciation:</u> speciation that is based on geographic isolation.
- <u>Sympatric Speciation:</u> organisms are reproductively isolated by postzygotic mechanisms and evolve into different species.
- <u>Allopatric Speciation:</u> organisms in different locations are subject to different selective pressures and evolve into different species.
- <u>Sympatric Speciation:</u> speciation that does not require geographic isolation.
- <u>Sympatric Speciation:</u> bread wheat evolved from two species of wheat with different chromosome numbers.
<h3>What is speciation?</h3>
Speciation can be defined as an ecological and biological process through which new species of a living organism are formed, especially due to isolation of a part.
<h3>The types of speciation.</h3>
In Science, there are five (5) major types of speciation and these include the following:
- Allopatric Speciation
- Peripatric Speciation
- Parapatric Speciation
- Sympatric Speciation.
- Artificial Speciation.

Allopatric Speciation Sympatric Speciation
Speciation that is based on geographic isolation

Answer:
The correct answer is -
1. c. both
2. b. gluconeogenesis
3. d. neither
4. b. gluconeogenesis
5. a. glycolysis
6. c. both
7. a. glycolysis
8. d. neither
Explanation:
Gluconeogenesis is the formation or synthesis of glucose while glycolysis is the conversion of glucose into pyruvate. Gluconeogenesis requires an enzyme for a non-reversal reaction which is not required in glycolysis.
Glyceraldehyde 3-phosphate dehydrogenase is an enzyme present in glycolysis that converts glyceraldehyde 3-phosphate to 1,3-bisphosphoglycerate. It is a reversible reaction, this enzyme also present during gluconeogenesis converts 1,3-bisphosphoglycerate to glyceraldehyde 3-phosphate.
Glucose 6-phosphate to glucose during gluconeogenesis by glucose-6-phosphatase. Alcohol dehydrogenase is used for the conversion of ethanol into acetaldehyde and neither present in glyconeogenesis nor glycolysis. Oxaloacetate converts to phosphoenol pyruvate during gluconeogenesis by Phosphoenol pyruvate carboxykinase.
Fructose 6-phosphate changes into fructose 1,6-bisphosphate by Phosphofructokinase-1 during glycolysis.
Phosphoglycerate mutase is present in both pathways during glycolysis and during gluconeogenesis. This enzyme converts 3-phosphoglycerate to 2-phosphoglycerate and also converts 2-phosphoglycerate to 3-phosphoglycerate in glycolysis and gluconeogenesis respectively.
Hexokinase converts glucose to glucose 6-phosphate during glycolysis. However, Pyruvate dehydrogenase neither present in glycolysis nor gluconeogenesis.
