What is the effect of a lack of nitrate ions on plant leaves?
А All leaves turn very dark green.
B Leaves lose their yellow colour.
C The leaves wilt.
D Young leaves grow very slowly.
Explanation:
Nitrate deficiency
Without nitrates, the amount of chlorophyll in leaves reduces. This means leaves turn a pale green or yellow colour. This reduces the plant's ability to photosynthesise and grow properly, which reduces the farmers' crop yield .
The leafes turns pale yellow when plants have lack of nitrate ions in the plants.
How nitrate defeciency occur in plants?Excessive irrigation and heavy rains cause nitrogen deficiency due to overwatering. A lack of soil moisture tampers with the absorption of water-soluble nutrients by plant roots.
Nitrates are present in high levels in plant fertilisers. Without nitrates, the amount of chlorophyll in leaves reduces. This means leaves turn a pale green or yellow colour. This reduces the plant's ability to photosynthesis and grow properly.

make a claim for how the cell cycle relates to the growth and maintenance of organisms
Every living thing is made up of cells. If cells did not exist, there would be no life.
Answer:
Most tissues of the body grow by increasing their cell number, but this growth is highly regulated to maintain a balance between different tissues. In adults most cell division is involved in tissue renewal rather than growth, many types of cells undergoing continuous replacement.
The multiplying of cells helps the body to either fight diseases or to keep up with the growth of adolescents all the way to adults.

Which level of a food pyramid represents the largest amount of organisms
Answer:
producers
Explanation:
:)
The level of a food pyramid which represents the largest number of organisms is the Producers level. Producers are the first trophic level of a food chain.
What are the Producers?Producers consist of the group of all the organisms which can produce their own food through the process of photosynthesis. They usually include all the green plants. These organisms trap the energy from the sun and use it to synthesize the carbohydrate (food) by the process of photosynthesis. All the other organisms depend on the producers for their food.
The bottom and largest level of the food pyramid is the producers and it contains the largest amount of energy in a food chain or a food web. As you move up in the pyramid, through the different trophic levels to primary, secondary and tertiary consumers, the amount of energy decreases and the levels become smaller and smaller in number as well as energy.

Answer:

Explanation:
When blood sugar (glucose) rises, the pancreas releases insulin into the bloodstream which helps in lowering the blood sugar level either by storing the excess glucose as fat or as glycogen.
This type of mechanism is regarded as a negative mechanism. It helps to regulate blood sugar level.
Therefore, the increase in insulin level when there's an increase in blood sugar level (glucose) can best be explained by a feedback mechanism that regulates blood glucose level.

The process of CELLULAR RESPIRATION?
Answers:
Converts water and carbon dioxide into oxygen and glucose, which releases energy as ATP
Uses ATP energy to convert glucose and oxygen into water and carbon dioxide
Converts glucose and oxygen into water and carbon dioxide, which releases energy as ATP
Uses ATP energy to convert water and carbon dioxide into oxygen and glucose
Answer:
Converts glucose and oxygen into water and carbon dioxide, which releases energy as ATP
Explanation:
Cellular respiration is the process in which sugars are broken down into energy that can be used, so energy - or ATP - must be a product. Also, the chemical equation for the process is the following (the reactants are on left side of the arrow while the products are on the right):
[tex]C_6H_1_2O_6 + 6O_2[/tex] ⇒ [tex]6CO_2 + 6H_2O[/tex]
So, since [tex]C_6H_1_2O_6 + 6O_2[/tex] represents glucose and oxygen and [tex]6CO_2 + 6H_2O[/tex] represents carbon dioxide and water, the answer must be the third option listed.

Which statement best compares eukaryotic cells and prokaryotic cells?
Answer:
Eukaryotes have a cell wall, while prokaryotes have a cell membrane. Eukaryotes use active transport to move substances across the cell membrane, while prokaryotes use facilitated diffusion.
Eukaryotic cells are multicellular but lack cell walls, whereas prokaryotic cells are single-celled and contain cell walls.
What is the difference between eukaryote and a prokaryote?Prokaryotic cells lack membrane-bound organelles, whereas eukaryotic cells do, including the nucleus. The presence of mitochondria and chloroplasts, the cell wall, and the makeup of chromosomal DNA are all examples of differences between the cellular structures of prokaryotes and eukaryotes.
Eukaryotic cells exists smaller than prokaryotic cells in size. Eukaryotic cells exists multicellular but lack cell walls, whereas prokaryotic cells exists single-celled and contain cell walls. Organelles such as mitochondria and nuclei are membrane-bound in both prokaryotic and eukaryotic cells. Cell membranes, DNA, and/or RNA are features shared by prokaryotic and eukaryotic cells. Eukaryotic cells are less able than prokaryotic cells to withstand settings with high pH levels.Eukaryotic cells are multicellular but lack cell walls, whereas prokaryotic cells are single-celled and contain cell walls.
