The theory was originally developed as island biogeography, to explain species richness of actual islands, principally oceanic. It proposes that the number of species found in an undisturbed insular environment is determined by immigration and extinction.
Explanation:
Wilson of Harvard, developed a theory of "island biogeography" to describe such uneven distributions. They suggested that the number of species on any island displays a balance within the rate at which new species establish it and the rate at which residents of secured species become extinct.
Answer:
The most likely reason some seeds are to be covered with only 1/4 inch of soil is that <u>the seeds require light to germinate.</u>
Explanation:
This seed packets does not say anyhing about temperature so we can rule out higher temperature. It is really rare to plant with seeds does not have any cotyledons and also we can't really know it from the question. Etiolation response can also be found in seedlings also from this question we can't know this for sure.
Only thing that is changes if you cover the seeds with only 1/4 inch of soil is light. If you completely cover this seed with soil it wouldn't grow.
Heterotrophs is the answer
Answer: Receptor protein.
Explanation:
The receptor protein on the cell surface would enable a cell to respond to glucagon. The glucagon binds to the GPCR on the liver and muscle cells and is known as glucagon receptor.
This receptor then stimulates cells to release glucose into the blood stream. Another hormones involved during this process is glucagon like peptide 1.
It works by binding to another GPCR which is GLP-1 receptor found on the pancreatic cells.
