Johnny is growing "tomatoes" in a light chamber in his dorm closet. some are given red light, some are given green light, and some are given blue light. under which color light will johnny's "tomatoes" show the greatest rate of growth?
Tomato plants grown under blue light will exhibit the greatest growth due to better absorption by chlorophyll used in photosynthesis, with red light being the second best for promoting growth and flowering, and green light the least effective for growth.
Chlorophyll a and b, which are found in tomato plants, absorb light most efficiently in the blue and red portions of the spectrum, with blue light being particularly good for promoting leafy growth. Green light, on the other hand, is less efficient for photosynthesis since it is reflected by the plants rather than absorbed.
Therefore, in Johnny's experiment with growing tomatoes under different colored lights, the plants grown under blue light (Plant A) would likely show the greatest rate of growth, followed by those grown under red light (not mentioned in the original question but generally known to promote growth and flowering), and finally those grown under green light (Plant B), which will show the least growth. Plant C, which is grown under orange light, may experience some growth due to the presence of red wavelengths in orange light, but likely less than plants under blue light. In summary, the predicted order from most growth to least growth would be blue light, red/orange light, then green light.

What types of products are labeled as ancient grains by food companies?
The type of product which is labeled as ancient grain by food companies is Freekeh.
Freekeh or farik is a grain food produced from green durum wheat that is grilled and rubbed to accomplish its flavor. It is an classical food obtained from North African cuisines, enduring popular in various nations of the eastern Mediterranean Basin where durum wheat introduced. Freekeh is low in fat and high in protein and fiber. The piles are deliberately set on fire in order to burn straw . Under these circumstances, the high moisture content of the grains stops them from burning. The roasted wheat is then thrashed and sun-dried to produce a consistent flavor, texture, and color.

Both organisms convert free nitrogen into nitrogen-containing compounds.
Both organisms convert nitrogen-containing compounds into free nitrogen.
The bacteria convert free nitrogen into nitrogen-containing compounds, while the decomposers convert nitrogen-containing compounds into free nitrogen.
The bacteria convert nitrogen-containing compounds into free nitrogen, while the decomposers convert free nitrogen into nitrogen-containing compounds.
Answer:
The bacteria convert free nitrogen into nitrogen-containing compounds, while the decomposers convert nitrogen-containing compounds into free nitrogen.
Explanation:
Nitrogen is an essential element for all living organisms. It is required for synthesis protein and nucleic acids and other nitrogenous compounds. Some nitrogen fixing organisms such as Rhizobium, fixes atmospheric nitrogen (N₂) into usable forms such as nitrate (NO₃⁻) or ammonium (NH₄⁺ ) in the soil. The plants take up (NO₃⁻) and (NH₄⁺ )by absorption from the soil by their roots and make protein and nucleic acids. Animals take up nitrogen by eating plants. On death of a plant or animal and the nitrogenous waste produced by animals, decomposers such as bacteria and fungi convert this organic nitrogen into ammonium (NH4⁺) and later into NO₂⁻ and NO₃⁻. Denitrifying bacteria change NO₃⁻ into free nitrogen (N₂).
The statement that compares the roles of nitrogen-fixing bacteria and decomposers in the nitrogen cycle is : ( C ) The bacteria convert free nitrogen into nitrogen-containing compounds while the decomposers convert nitrogen-containing compounds into free nitrogen
What Happens in the Nitrogen cycleNitrogen is essential for every living organism because in the Nitrogen cycle, nitrogen fixing organisms ( Rhizobium ) fixes nitrogen into the soil in the form of nitrate or ammonium ( NH₄⁺ ).
The nitrate and ammonium is taken up by the plants by absorption through its roots and is used for the production of protein and nucleic acids .as the plants die the bacteria convert the nitrogen compounds into free nitrogen.
Hence we can conclude that The bacteria convert free nitrogen into nitrogen-containing compounds while the decomposers convert nitrogen-containing compounds into free nitrogen

Hence, responsible for increasing soil fertility.
The parents of a 6-year-old tell the school nurse that they are worried that their child will fall behind other children academically because they are not able to afford expensive toys like computer games and handheld electronic devices. which are acceptable responses by the nurse? select all that apply.
Answer:
The nurse should say that expensive toys are not a factor responsible for the good academic development of preschoolers. She should also mention that there are simple and inexpensive toys that are perfect for children at this age. Lastly, the nurse should indicate which toys parents could buy for this child such as dolls, puzzles, crayons and Play-Doh.
Explanation:
Some educational toys help stimulate the senses and develop children's skills, for example by getting them to come to conclusions on their own. They can (and should) begin to be used even at preschool age as it is during this time that little ones begin to develop cognitive, physical and social aspects. These toys, however, need not be expensive and far-fetched. Simple toys like lego, puzzle, color pencils are great options for this.

Would you expect the salinity of the ocean to be high or low in a rainy region near the mouth of a river?
I would expect the salinity to be low. The rainy regions will feed a lot of fresh water to the river that drains into the ocean. This water will dilute the salty waters at the mouth of the river. This is one of the reasons why the salinity of brackish water varies over seasons influenced by the amount of fresh water brought in by the inland river.
