<span>The question is providing us with the following scenario:The frog population in the Amazon basin varied. Every 500 years, there was a mutational change leading to speciation. In between, the population remained the same with no observable changes. This pattern of microevolution is called punctuated equilibrium. This pattern is distingushed by long periods of lack of change, followed by a sudden and often extreme change, and followed again by a period of a lack of change. </span>
Ansywer: (C) The hypothalamus is located in each endocrine gland to help regulate functioning.
Explanation: Hypothalamus is located at the base of the brain lying below the thalamus (in the third cerebral ventricle).
Hypothalamus is connected to pituitary gland and both modulates transmission of stimuli. It also regulates internal functioning in response to external stimuli and other functions.
Thus, all the above options are correct EXCEPT “it is located in each endocrine gland to help regulate functioning”.
It is basic. I don’t know if I’m answering your question correctly.
They are fatty acids. Prostaglandins are the group of physiologically active lipid compounds called eicosanoids which having diverse hormones like effects in animals.
They are unsaturated fatty acids that contains cyclopentane ring and drives from 20-carbon , poly-saturated fatty acid precursor arachidnoic acid.During pain there are high concentration can causes by direct action upon nerve endings.
The estrogen based food is consume, the more likely uterine lining become abnormally thick. They play very important role in generation of the inflammatory response. Prostanglandins biosynthesis is significantly increased in inflamed tissue and they contribute to the development of cardinal of acute inflammation.

The activation energy needed for the chemical reaction decreased by an Enzyme.
Activation energy is the amount of energy required in a chemical reaction.
Enzymes lowers the activation energy by increasing the rate of reaction.
The energy required for a reaction to start is called activation energy. Enzymes are proteins that lower the activation energy of a reaction. In doing this, enzymes increase the rate of a reaction, helping it to occur faster. However, enzymes are not consumed in a reaction; they simply help it to occur.
