Answer:
C. Foliated or nonfoliated
Explanation:
This occurs when a molecule of adenosine diphosphate (ADP) uses the energy released during cellular respiration to bond with a thirdphosphate group, becoming amolecule of ATP. So the energy from cellular respiration is stored in the bond between the 2nd and 3rdphosphate group
Answer:
insulin; pancreas.
Explanation:
An endocrine system refers to a series of ductless glands and organs responsible for the production and secretion of hormones that are used by the body for the performance of various functions such as metabolism, controlling growth, reproduction, mood, sleep, etc. These hormones are secreted directly into the circulatory system (blood) and then transported to the organs and tissues in the body.
Basically, the endocrine system contributes significantly to the state of homeostasis in the body.
Homeostasis can be defined as a process through which a living organism maintains a steady or stable physical, internal and chemical environment that is ideal to enhance life and proper functionality.
Generally, when the blood glucose levels of a person rise, through an endocrine system, the hormone known as insulin is released from the pancreas to convert excess glucose into glycogen, which is typically a short-term energy storage molecule for the body.
In conclusion, the endocrine system maintain homeostasis by releasing insulin from the pancreas to decrease blood sugar and releasing glucagon to increase blood sugar.
Answer:
Chlorophyll is a green pigment found in chloroplast in plants. It absorbs sunlight during the process of photosynthesis. It is a chelate molecule. In a chelate molecule a central metal ion forms bonds with a large organic molecule made of carbon, hydrogen and other elements like nitrogen or oxygen.
In chlorophyll, magnesium is the central metal ion and it is bonded to a large organic molecule called as porphyrin. Porphyrin constitutes four nitrogen atoms to which the central magnesium is bonded in square planar arrangement. Since chlorophyll is responsible for the green color of the leaves, more the green color more the chlorophyll content and more is the nitrogen content. Hence, chlorophyll meter measures this green light and finds out if the plant needs more or less nitrogen.
Answer: the two tropics zones
Explanation:
Between the two tropics zones, which includes the equator, the Sun is directly overhead twice per year. Outside the tropic zones, whether to the south or north, the Sun is never directly overhead. Two other significant lines of latitude are the Arctic Circle (around the North Pole) and the Antarctic Circle (around the South Pole).
