Answer:
Mass
Explanation:
Mass is defined as the amount of matter in a substance. It is usually measured by balances such as the beam balance and scales. It is measured in grams or kilograms depending on the size of the body.
The process of Rock formation involves how a rock is formed which is usually by sedimentation or cooling of magma in volcanic eruptions. In rock formation study,the geologist measures the mass of the rock which enables knowledge of the amount of matter in the rock. This is be used to determine the weight of the rock and the rock type and properties.
Answer:
The alarm reaction stage
Explanation:
According to Selye, there are three stages of reaction to stress conditions. These are namely the alarm reaction stage, the resistance stage, and the exhaustion stage.
The alarm reaction stage is the first stage of stress reactions which includes perception of stress conditions. The hypothalamus sends signals to the associated glands and organs to prepare for the defensive responses.
The adrenal gland receives a signal to secrete the stress hormones while organs such as the liver are signaled to increase the glucose formation which in turn would serve as fuel during stress conditions.
The OH on the lower right of lysine and the H on the lower left of valine combine to form a molecule of water (H2O) and detach in a process known as a dehydration reaction when the two amino acids bond. The C on the right side of lysine then single bonds with the N on the left side of valine. This bond is termed a peptide bond. All the other bonds remain unchanged.
