Organisms differ in how they obtain energy, and they are classified as autotrophs or heterotrophs based on how they obtain their energy in an ecosystem. ... organisms that contain chlorophyll absorb energy during photosynthesis and use it to convert the inorganic substance carbon dioxide and water to organic molecules. Why?
Explanation:
Answer:
The time required for the colony to grow two million bacteria is 29.22.
Explanation:
Time required for the colony to grow can be calculated by the following equation:

Here t is time, N = 2 million (require bacteria population).

t ≈ 29.22
Time taken by bacteria to grow is 29.22.
Maintaining Homeostasis. The process in which organ systems work to maintain a stable internal environment is called homeostasis. ... Endocrine system: A high concentration of sugar in the blood triggers secretion of insulin by an endocrine gland called the pancreas.
The normal blood glucose level (tested while fasting) for non-diabetics, should be between 3.9 and 5.5 mmol/L (70 to 100 mg/dL). ...
Blood sugar levels for those without diabetes and who are not fasting should be below 6.9 mmol/L (125 mg/dL).
There are lots of different hormones in the human body that serve lots of different functions, but some are used to maintain homeostasis of various physiological parameters, like blood glucose levels. Blood glucose levels are regulated by two opposing hormones: insulin and glucagon.
