Drinking extra fluid has many advantages (not only one):

Good regular hydration helps to regulate body heat and to compensate for sweat losses during an effort. When you sweat, you lose water but also Sodium and to a lesser extent other minerals such as Potassium, Magnesium, Zinc or Copper. This Sodium is necessary since it improves hydration by optimizing cellular exchanges.

It is also important to drink regularly, and this from awakening (not only in athletic events), to restore our blood to its normal consistency. After ingestion of water, it is absorbed by the intestines and then reaches the bloodstream. The water then mixes with the blood and dilutes the clotting factors. With less viscous blood, cardiovascular risks are limited.

Ne4ueva [31]

Answer:

The following four traits are -:

Pedigree 1 - A recessive trait (autosomal recessive) is expressed by pedigree 1.
Pedigree 2- Recessive inheritance is defined by Pedigree 2.
Pedigree 3 - The inheritance of the dominant trait (autosomal dominant) is illustrated by Pedigree 3.
Pedigree 4- An X-like dominant trait is expressed by Pedigree 4.

Explanation:

Explaination of each pedigree chart-

Pedigree 1 demonstrates the recessive trait since their children have been affected by two unaffected individuals. If the characteristics were X-linked, in order to have an affected daughter, I-1 would have to be affected. $X^A$ In this, both parents are autosomal recessive trait carriers, so the child will be affected by a 1/4 (aa)
Recessive inheritance is defined by Pedigree 2. This is X-related inheritance as autosomal recessive inheritance has already been accounted for in part 1. This inference is confirmed by evidence showing that the father (I-1) is unaffected and that only the sons exhibit the characteristic in generation II, suggesting that the mother must be the carrier. The individual I-2 is a carrier for this X-linked trait. A typical Xa chromosome is attached to the unaffected father (I-1), so the chance of carrier II-5 is 1/2. Probability of an affected son = 1/2 (probability II-5 is a carrier) x 1/2 (probability II -5 contributes ( $X^A$ ) x 1/2 (probability of Y from father II-6) = 1/8. An affected daughter's likelihood is 0 because a typical $X^A$ must be contributed by II-6.
The inheritance of the dominant trait is demonstrated by Pedigree 3 because affected children still have affected parents (remember that all four diseases are rare). The trait must be autosomal dominant because it is passed down to the son by the affected father. There is a 1/2 risk that the heterozygous mother (II-5) would pass on mutant alleles to a child of either sex for an autosomal dominant feature.
Pedigree 4 is an X-linked dominant function characterized by the transmission to all of his daughters from the affected father but none of his son. On the mutant X chromosome, the father (I-1) passes on to all his daughters and none of his sons. As seen by his normal phenotype, II-6 therefore does not bear the mutation. An affected child's likelihood is 0.

The evolution of similar forms in different lineages when exposed to the same selective pressures is.

luda_lava [24]

The evolution of similar forms in different lineages when exposed to the same selective pressures is convergent evolution.

Convergent or divergent evolution are related to the involved groups, the environments, the selective pressures, and the way in which organisms deal with them to achieve a better adaptation increasing their fitness.

<h3>What is convergent evolution?</h3>

Convergent evolution is the emergence of phenotypical similarities in different groups independently from each other.

Convergent evolution occurs when two or more taxonomic groups share the same traits or characteristics even when they do not share a common ancestor.

Usually, this is a pattern observed in groups that are exposed to the same or similar environmental pressures. The development of these similar phenotypes is related to higher fitness and competitive ability.

The evolution of similar forms in different lineages when exposed to the same selective pressures is convergent evolution.
