D can be eliminated because the temperatures where changed in 3 ways, not two.
A is true, but doesn't apply to the actual experiment "design"
B we don't know for sure, it just looks like a cup/glass.
Best answer for you: C
C is true- it was tested with a single independent variable (one that does not change) on multiple trials (the different temperatures)
Scientific inquiry requires logical ideas that can be tested
Could I please Have Brainliest?
The correct answer is: E) provide the defense for the CNS
Astrocytes are star-shaped cells found in central nervous system (brain and spinal cord) .Some of their functions include:
• Support of neurons by supporting endothelilal cell of blood–brain barrier,
• Provide nutrients to neurons
• Maintain ion balance and thus controlchemical environment around neurons
• Repair of injuries in the brain
• the secretion or absorption of neural transmitters…
The cells that provide the defense for the CNS are called microglia. Those cells are also glial cells, derived from macrophages and thus, part of active immune defense.
Well a small baby whale can eat about 200 pounds in a day
An adult whale can eat roughly about 6 TONS of food per day-
Oxygen is an abiotic factor that is beneficial by-product of primary production.
<u>Explanation:</u>
The non living parts of an ecosystem that mainly affects the living organisms in it are called as an abiotic factor. These can include soil, temperature, water, oxygen and sunlight. The major energy source in earth is Oxygen which is abiotic factor.
It is very essential for the photosynthesis process to take place. Here, the plants converts water and carbon dioxide into oxygen and sugar. This becomes food for plants. Then these plants are eaten by animals. Thus oxygen is an important and beneficial by-product of photosynthesis. Oxygen is also very important for the survival of human beings.
