Answer: b. from the sun
Explanation:
Most of the producers are the plants and other autotrophic organisms that obtain their energy from the light energy of sun. These organisms use the light energy from sun to convert this energy into chemical energy of food by the process of photosynthesis. In the absence of sunlight energy photosynthesis will not occur. The ingredients like water and carbon dioxide are used to produce oxygen and carbohydrates in the presence of sunlight.
Answer:
liquid, with an average density of approximately 11 g/cm3
Explanation:
The outer core of the Earth is inferred to be a liquid layer composed of iron, nickel, and sulfur, compressed to a high density. It's responsible for generating Earth's magnetic field due to the circulation of the liquid metal inside. Notably, its diameter makes it larger than the planet Mercury.
The outer core of Earth is inferred to be a dense, metallic layer, over 2900 kilometers beneath the Earth's surface. It's chiefly composed of iron, nickel, and sulfur, compressed to a very high density. Quite fascinatingly, the outer core, unlike the solid inner core, is liquid.
This liquid state facilitates the circulation of metallic elements within it, helping generate Earth's magnetic field. As the liquid metal inside Earth moves, it sets up a circulating electric current, which subsequently produces a magnetic field.
For size perspective, it's worth noting that with a diameter of approximately 7000 kilometers, Earth's core is larger than the planet Mercury. This fascinating core, and particularly its outer liquid layer, provides key insights into understanding not only earth's geodynamic movements but also the formation of its protective magnetosphere.

Answer:
Although uncommon, it's possible to drink too much water. When your kidneys can't excrete the excess water, the sodium content of your blood is diluted (hyponatremia) — which can be life-threatening.

Answer:b
Explanation:
Ian would take DNA samples from the inside of the suspects' mouths if he were asked to swab their buccal surfaces.
Identification and comparison are the two techniques forensic scientists utilize when assessing tangible evidence. Determining a substance's physical or chemical identity is the process of identification. Finding out whether two or more objects have a common origin is done through comparison.
In regard to matching, DNA analysis is comparable to fingerprint analysis. The evidence gathered at the crime scene is contrasted with a "known" print or sample when a suspect is identified using DNA or a fingerprint.
