The guidelines for making good and accurate observations are:
1. Standardise the experimental setup: Know the precision and the accuracy of the instrument used to make observations. Example, thermometer with a least count of 1°C cannot measure in fractional values.
2.Take careful measurements: Holding the instrument properly without causing any disturbance is the key.
the right answer is B- energy from magma at divergent boundaries are cleaner
Hormones appear to be influenced by emotion and external behavior. For example, one's activity level may increase the production of a hormone, just as hormones often influence the way an individual feels. Hormones are found to impact behavior indirectly through emotional experiences. For example, an individual may feel a specific way as a result of hormone fluctuations but not behave or act out accordingly. The interaction between the emotion and environment play a large role on how hormonal influences are expressed behaviorally. Hormone production also appears to influence various behaviors.
