30 grams of ammonia (NH3), nitrite (NO2-), and nitrate (NO3-) are added to a soil sample.
Predict whether these concentrations would increase, decrease, or stay the same if nitrite-nitrifying bacteria were added to the sample.
Answers
If 30 grams of ammonia (NH3), nitrite (NO2-), and nitrate (NO3-) are added to a soil sample and nitrite-nitrifying bacteria are added, the concentration of the nitrate would increase, that of the nitrite would decrease, while that of ammonia would remain the same.
The process of converting ammonia to nitrate, also known as nitrification occur in two stages:
The conversion of ammonia to nitrite by ammonia oxidizing bacteria.The conversion of nitrite to nitrate by nitrite-oxidizing/nitrifying bacteria.Now, if nitrite-nitrifying bacteria is added to the soil sample above, it means that only the nitrite would be converted to nitrate. The bacteria will not be able to oxidize ammonia.
Hence, some of the nitrite would be converted into nitrate leading to the reduction in the concentration of the former, and an increase in the concentration of the latter. The concentration of ammonia will remain unchanged.

Photosynthesis Takes Place in Chloroplasts. ... The inner membrane surrounds a stroma, which is the site of the carbon chemistry of photosynthesis
sorry if im wrong
Photosynthesis occurs in chloroplast thylakoid membranes. Electron transport chains produce ATP and NADPH. Therefore, option (A) is correct.
What are chloroplasts?Chloroplasts are plastids that are made up of an outer membrane, an inner membrane, grana, and the stroma. These four components make up the chloroplast. The inner membrane encloses a region that is filled with fluid and is known as the stroma. This region includes enzymes that are responsible for light-independent processes that occur during photosynthesis. When this inner membrane is folded inward, it creates linked stacks of disk-like sacs known as thylakoids. These thylakoids are frequently grouped in stacks that are called grana.
The chemical reaction known as photosynthesis, which converts sugar and oxygen from carbon dioxide and sunlight, takes place in chloroplasts, which are found in plant cells.

Explanation:Make sure u read!!!!
The correct answers are C. Blue light has a longer distance between wave crests than red light, and E. Orange light has a shorter distance between wave crests than violet light.
What is visible light?Visible light waves are a type of electromagnetic radiation that are visible to the human eye. They make up a small portion of the electromagnetic spectrum and have wavelengths that range from about 400 nanometers (nm) to 700 nm. Visible light waves can be separated into colors of the rainbow, including red, orange, yellow, green, blue, indigo, and violet.
Each color of visible light has a unique wavelength and frequency. Red light has the longest wavelength and the lowest frequency, while violet light has the shortest wavelength and the highest frequency. This means that red light has a longer distance between wave crests than violet light, and violet light has a shorter distance between wave crests than red light.

What is never found inside the lipid bilateral of a cell membrane
Answers
Answer:
Cell membranes restrict diffusion of highly charged molecules, such as ions, and large molecules, such as sugars and amino acids.
Explanation:
Cell membranes serve as barriers and gatekeepers. They are semi-permeable, which means that some molecules can diffuse across the lipid bilayer but others cannot. Small hydrophobic molecules and gases like oxygen and carbon dioxide cross membranes rapidly. Small polar molecules, such as water and ethanol, can also pass through membranes, but they do so more slowly. On the other hand, cell membranes restrict diffusion of highly charged molecules, such as ions, and large molecules, such as sugars and amino acids. The passage of these molecules relies on specific transport proteins embedded in the membrane.

Answers
Answer:
B. Eukaryotic cells
Explanation:
Prokaryotic cells are only seen in unicellular organisms as bacteria and cancer cells are just cells where there has been an error in division or a mutation.
If an organism is multicellular, it probably has - option B.) Eukaryotic cells.
Cells are of mainly two types prokaryotic cells and eukaryotic cells. The main difference between eukaryotic and prokaryotic cells is that:
Eukaryotic cells have a nucleus in which genetic material is stored enclosed by a nuclear membrane.All prokaryotic cells only form single-celled (unicellular) organisms without a true nucleus or membrane-bound structures, examples of prokaryotes are bacteria and archaea. Organisms with eukaryotic cells are called eukaryotes that can be either multicellular such as animals, plants, fungi, and protists, or single-celled as well. So, all multicellular organisms are eukaryotes..Thus, If an organism is multicellular, it probably has - option B.) Eukaryotic cells.
