Answer:
B. False
Explanation:
Orthologs are genes that find their origin in vertical descent,, paralogous on the other hand, are genes that are related via duplication events. <em>In the case of human hemoglobin, their genes originated by duplication from an common ancestral globin gen, therefore they are paralogous.</em>

Answer:
There is some debate about the definition of a species, especially across fields. However, what it likely being discussed here is the biological species concept which states that:
An organism is considered a new species when there is reproductive isolation from the population that they originated from. In other words, for two organisms to be the same species they must be able to reproduce to create viable (able to survive) and fertile (able to reproduce) offspring.
Reproductive isolation can occur by different means, classified as being prezygotic or postzygotic isolation. These include things like mechanical, behavioral, temporal, ecological, and geographical isolation for prezygotic isolation. And things like hybrid infertility and hybrid inviability for postzygotic isolation. These are not relevant to the question but they give you an idea of what you could look up if you wanted more information.
Answer:
Autotrophs
Explination: They are called this because they use the energy and simple inorganic compounds to produce organic molecules.
Answer:
The correct answer is C in presence of oxygen production of acetyl CoA,TCA cycle and electron transport chain occur in a proper order.Whether in absence of oxygen lactic acid fermentation or alcoholic fermentation occurs.
Explanation:
Aerobic respiration occur in presence of oxygen which involves glycolysis,TCA cycle and electron transport chain.Aerobic respiration result in the catabolism of glucose to generate CO2,H2O and ATP.
But in absence of oxygen or during anaerobic condition pyruvic acid is converted to either lactic acid by pyruvate dehydrogenase or to ethanol through alcoholic fermentation.
Answer: Diploid cells contain two complete sets (2n) of chromosomes. Haploid cells have half the number of chromosomes (n) as diploid - i.e. a haploid cell contains only one complete set of chromosomes. Diploid cells reproduce by mitosis making daughter cells that are exact replicas.
