Answer:
If one parent has blood type B and the other parent has blood type O, the percentage of the blood type of the offspring will depend on the genotype of the parent with blood type B.
Explanation:
Knowing the blood type of the offspring of the cross between parents with blood type B and O raises two possible scenarios, depending on whether the genotype of the parent (type B) is B|B or B|O.
Blood type is an inherited trait and is characterized by the presence or absence of surface antigens A and B in the red blood cells, which genetically behave as co-dominant traits.
- <em>Blood type A</em><em> contains antigen A and its genotype can be A|A or A|O.
</em>
- <em>Blood type B </em><em>contains the B antigen, whose genotype can be B|B or B|O.
</em>
- <em>Blood type AB </em><em>contains both antigens and a single A|B genotypic expression.
</em>
- <em>Type O blood lacks surface antigens, and is the recessive trait so its genotype is O|O.</em>
<u>Scenario 1: Parent with genotype B|B.</u>
In this case, knowing that the genotype for type O is always O|O, all offspring would be of blood type B, genotype B|O.
B|B X O|O
Alleles B B
O B|O B|O
O B|O B|O
100% of the offspring would be of blood type B.
<u>Scenario 2: Parent with genotype B|O.</u>
In this case, 50% of the offspring will have blood type O and 50% B.
B|O X O|O
Alleles B O
O B|O O|O
O B|O O|O
In no scenario would offspring of blood type A be possible.
Answer:
Athletes who train short distances and explosive moments of extreme metabolic anaerobiosis have a higher percentage of fast fibers in the muscular structure of skeletal muscles, that is, in the muscles that achieve and carry out locomotion.
Some researchers also argue that men have a predisposition to have more fast fibers than women, since these are predominantly slow fibers.
Rapid muscle fibers to the leg muscle, generating more powerful contractions with less presence of oxygen and greater lactic acidification in the metabolism of the energy currency.
Explanation:
Fast and slow fibers are two different types of fibers, these are usually trained according to the histology or physiology of each athlete.
Those with the highest amount of fast fibers will train and perform better in high-power physical activities, that is, for short distances with little demand for oxygen.
Answer:
Pairs of Genetic Factor (genes) would be the right answer.

Answer:
Phylogeny.
Explanation:
Classification may be defined as the process of classifying the organisms into same or different groups depending on their similarities and differences. Carolus Linnaeus is known as the father of taxonomy.
Carolus believes in the fixity of species but the statement proves wrong as the species evolve with time. Linnaeus had been uncomfortable with the phylogeny or the evolution of the organism. His idea of the fixity of species is in contradiction with the phylogeny.
Thus, the correct answer is option (4).
