Researchers argue that some bacteria found in the human gut are in a symbiotic relationship with humans, called mutualism. Which
Rama09 [41]

Answer:

Bacteria provides vitamins to humans

Explanation:

The correct answer would be that bacteria provides vitamins to humans.

<u>By definition, mutualism is a type of symbiotic relationship between two organisms in which both benefit from each other.</u>

Bacteria in the gut of humans that provides vitamins to humans also benefit by making the human gut their shelter. While the vitamins represent an important nutrient to humans for their proper functioning, the shelter is also necessary for the bacteria for their safety.

<em>Hence, the observation that bacteria provide vitamins to humans is consistent with the argument of researchers that some bacteria found in the human gut are in a mutually beneficial relationship with humans.</em>

Glucose-6-phosphate dehydrogenase deficiency (G6PD) is inherited as an X-linked recessive allele in humans. A woman whose father
prohojiy [21]

Answer:

(a) 1/2; (b) no

Explanation:

Glucose-6-phosphate dehydrogenase deficiency (G6PD) is an X-linked recessive disorder and the woman's father was diseased so it means that woman is a carrier of the allele but has normal phenotype. It means that she will have XXᵇ genotype.

In contrast to this, her husband is diseased so his genotype will be XᵇY.

The Punnett square diagram related to the cross is attached.

(a) Proportion of their sons expected to be G6PD is 1/2:

They both may give birth to 4 progeny with genotypes XXᵇ, XᵇXᵇ, XY and XᵇY. It means they both may have 2 sons out of which one with genotype XᵇY will be diseased while the one with genotype XY will be healthy. So the proportion of their sons having G6PD is 1/2 or 50%.

(b) If the husband were G6PD deficient, the answer will not change.

The reason behind this is that this disease is caused by an allele located in X chromosome. But father contributes only Y chromosome to his son not X chromosome. The X chromosome will affect the genotype of his daughter not son that is why answer will not change. It means they will still have 1/2 of their sons diseased.

Anit [1.1K]

Answer:

Predator-prey relation.

Explanation:

A predator is defined as an organism that hunts another individual, whereas a prey refers to the organism that is eaten by the predator. They tend to co-evolve (evolve together). <u>The prey is essential for the predator to survive, while the predator controls the prey populations by hunting some of the individuals.</u>

Predator-prey relations are interactions that occur between two species where one species (prey) represents a food source for the other species (predator).

The turtle (prey) is essential for the survival of the jaguar (<em>Panthera onca)</em>, while the jaguar controls the populations of turtles by preying upon them. Therefore, this is a predator-prey relation.
