Glucagon is a peptide hormone, PRODUCED by alpha cells of the pancreas.
Insulin is a hormone made by an organ located behind the stomach called the pancreas. There are specialised areas within the pancreas called islets of Langerhans (the term insulin comes from the Latin insula that means island).
And Islet cells in the pancreas are responsible for releasing both insulin and glucagon.
Glucagon raises concentration of glucose and fatty acids in the bloodstream, and is considered to be the main catabolic hormone of the body.[3] It is also used as a medication to treat a number of health conditions. Its effect is opposite to that of insulin, which lowers extracellular glucose.[4] It is produced from proglucagon, encoded by the GCG gene.
Answer:
New species develop when:
D. Diverging species no longer recognize one another as potential mates.
Explanation:
- The development of two or more new species from ancestral population is known as speciation.
- Speciation can occur when the population divides into groups and each group occupies a different habitat (geographic isolation) or when the members of the same population do not find one another as potential mate and do not interbreed (reproductive isolation mechanism).
- The three types are: Allopatric speciation.
Sympatric speciation.
Parapatric speciation.
- Allopatric speciation occurs when genetic divergence is allowed through geographic isolation.
- Sympatric speciation does not involve geographic isolation but involves reproductive isolation mechanisms.
- In Parapatric speciation, a population enters a new niche or habitat within the range of parent species and then evolution of reproductive isolation mechanism occurs.
It is very important because it controls behaviors essential to the life, such as the desire to eat and drink. ... The cingulate gyrus is located in a fold of the brain, and is involved in sensory input for emotions and regulating aggressive behavior. The diencephalon includes the thalamus and hypothalamus.
