<span>The answer for this question would be: a portion of the heme group
Stercobilin is metabolized from heme of the hemoglobin. Iron from hemoglobin will be recycled and the heme part will turn into bilirubin which will be dump into feses. Inside intestine, bilirubin will be converted into urobilinogen then oxidized into stercobilin</span>
All of the seagulls that live along the coast would best describe a population.
<h3>What is a population?</h3>
A biological population refers to a group of organisms of the same species living in a particular area at a particular time.
In other words, there can be more than one population of organisms in an area if more than one species of organisms occupy that area.
Thus, seagulls represent a species of organism. All of the seagulls living in an area will, therefore, constitute a population of seagulls.

Answer:
C.The two species do not breed in the same area, so they are reproductively isolated by allopatry.
Explanation:
Allopatry means that these two species are geographically separated during the breeding season, so they are reproductively isolated.
Allopatric speciation is a form of speciation (creation of new species) that occurs as a result of geographic isolation. This means that a part of population becomes physically separated from the initial main population. There is no gene flow between these two populations and as a result the two populations reach a high level of genetic divergence. They can no longer interbreed which means they become two different species (speciation).
<span>The correct answer is b.0.5 to 1 micrometre thick.</span>
Usually, the respiratory membrane is about 0.6 micrometres thick. This membrane consists of the alveolar epithelial cells, the capillary endothelial cell, and basement membranes which are formed by the alveolar and capillary cells.
