Explanation:

The red blood cells are formed in the marrow of the bones and are released into the blood. The red colour of the blood is as a result of of presence of haemaeglobin in the red blood cells. Haemaeglobin is an iron compound which combines with oxygen to form oxyhaemoglobin. The red blood cells transports oxygen in the form of oxyhaemoglobin to tissues all over the body.

Mashcka [7]

Answer:

The correct answer is allopatric speciation.

Explanation:

Allopatric speciation occurs when a geographical barrier comes between a species population living in the same area. This geographical barrier separates the population into two different geographical area which do not have the same condition.

So as both the separated population get different habitat environment to live so they evolve differently from each other. So natural selection and genetic drift works differently in both the population which brings genetic changes in the population and helps in creating a new species.

Is the surface temperature of white dwarf stars higher or lower than red super giants?
finlep [7]
<span>The surface temperature of white dwarf stars is higher than that of red super giants. White dwarf stars are extremely hot when they form, and they start cooling off as time goes by. Red supergiants, on the other hand, are enormous dying stars, and they are quite cool. So, having this in mind, white dwarves are hotter than red supergiants. Hope I helped! :) Cheers!</span>
