Answer:
Hyaline Membrane Disease
Explanation:
Hyaline Membrane Disease or the respiratory distress syndrome is a disease caused in newborn babies especially in premature infants due to the absence of the biological surfactant.
A glassy membrane composed of the dead cells and the protein is formed and lines the tiny sacs called alveoli which decreases the volume of the alveoli and difficulty in the exchange of gases in the infants.
Thus, Hyaline Membrane Disease is the correct answer.
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.
There are many causes to speciation, a) geographic isolation, b) gene flow reduction, and c) reproductive isolation.
Echinoderm is the name given to a member of the phylum Echinodermata. They have radial symmetry and this includes sea urchins, sand dollars, sea stars and sea cucumbers. It is suggested that they are related to the chordates which is the answer.
Modern stromatolites – living fossils. Originating over 3 billion years ago, stromatolites are the oldest known fossils (timeline). Fossilized stromatolites were laid down as colonial structures built by photosynthesizing Cyanobacteria and other microbes.
A sample is termed REPRESENTATIVE SAMPLE if it has similar characteristics to the population being studied.
The representativeness of a sample is the extent to which its characteristics accurately reflects the characteristics of the population being studied.
