Goshia [24]
The process where a specie develops and evolves into new many species is termed as speciation. Macroevolution explores the mechanism of speciation where organisms across biological populations evolve as distinct population.

lina2011 [118]
<span>For calcium to be absorbed it must bind to a hormone regulated brush border protein called Calbindin.
Calbindins are calcium binding protein. As it names also shows that, Cal for calcium and bindin for binding. they are also described as vitamin D dependent calbindin proteins.
Calbindin-D9k and Calbindin-D28k are two identified forms of protein. </span>

The magnetic particles in seafloor ridges are aligned differently in a repeating pattern. How
Mademuasel [1]

A. Earth's magnetic field reverses over time;  the changes show that seafloor spreading  has taken place over time.

Explanation:

The pattern of the magnetic minerals in seafloor ridges are aligned in a repeating pattern because the earth's magnetic field reverses overtime.

This provides evidence because the changes shows that the sea floor spreading has taken place over time.

  • The concept of sea floor spreading was first suggested by Harry Hess in the early 1960's.
  • Using sophisticated tools, he was able to discover stripe patterns of magnetic minerals in rocks.
  • The earth can be likened to a giant bar magnet
  • The geomagnetic field originates from the core where the movement of molten metals induces magnetism.
  • In a fresh cooling magma, the metallic minerals are able to align their domains with the prevailing magnetic field.
  • At some point the magnetic field is normal with a very strong intensity. At other times the intensity is low and it reverses.
  • The minerals keeps track of the changes.
  • This leads to striped pattern that has been used to suggest sea floor spreading.

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.
