Herbicides are compounds that are used to eliminate undesirable weeds without damaging desired plants or crops.
A few herbicides have a broad spectrum of action and destroy weeds without targeting any particular weed species. A herbicide that interferes with ATP synthase will cause a decrease in ATP production since this enzyme uses a proton gradient to catalyse the synthesis of ATP. The herbicide triazine is an illustration of this class. A proton gradient that is formed in the thylakoid lumen, through the thylakoid membrane, and into the chloroplast stroma is used by ATP synthase to produce ATP during photosynthesis in plants.

Create a life hierarchy of organization (choose a different organ system than the nervous system). Give definitions and examples from Ecosystem down to the atom.
A life hierarchy of organization is atomic- molecular- cellular- tissue-organ - organism - group- population- community- ecosystem- landscape- biosphere. This is the living hierarchy of organization.
What is ecosystem?
Ecosystem has been defined as the community that has biological by nature and the organism in that particular community attract with each other as well as their physical environment. Ecosystem has been consist of both biotic as well as abiotic factor. The living components of the ecosystem comes in category of biotic factor and non living components of the ecosystem comes in the category of abiotic factor.
Ecosystem has the community that has biological by nature and the organism in that particular community attract with each other as well as their physical environment.

Why do oxygens form double bonds?
Answer:
Each oxygen has 6 electrons and so need to share to more and so makes two bonds with the other oxygen.
Explanation:
Each oxygen has 6 electrons and so need to share to more and so makes two bonds with the other oxygen.
Below are the reduction half reactions for chemolithoautotrophic denitrification, where hydrogen is a source of electrons and energy and nitrate is the terminal electron acceptor.
NO3- + 10e- -> N2 (E0 = +0.74 V)
H+ + 2e- -> H2 (E0 = -0.42 V)
If you balance and combine the reactions so that 90 moles of H2 gas are oxidized to H+, how many moles of N2 gas will be produced?
39462 KJ of Gibbs free energy will produce. Number of moles of nitrogen = 90 moles, E0 = 0.74 + ( - 0.42) = 0.74 - 0.42 = 0.32
What is a Balanced chemical equation?A balanced chemical equation has the same number of reactants and products. We can balance a chemical equation by adding a number to adding the same number of molecules on both sides.
In this equation,
10NO3 + 10 e - -> 5N2
4H + 2 e - -> 2H2
In this equation, 5 moles of N2 and 2 moles of Hydrogen are produced.
5 * 0.74 = 3.7 V
2 * ( -0.42) = - 0.84 V
ΔG = -nFΔE,
where F = 96.48 kJ (mol e-)
= 90 * 96.48 * (3.7 + 0.84)
= 90* 96.48* 4.54
= 39462 KJ
Therefore, 39462 KJ of Gibbs free energy will produce. Number of moles of nitrogen = 90 moles, E0 = 0.74 + ( - 0.42) = 0.74 - 0.42 = 0.32.

Sarah and Michael were visiting their friend Regina. They were in Regina's backyard, enjoying some ice-cold lemonade. They noticed that there were droplets on the outside of the pitcher of lemonade. The 3 friends made the following claims: A. Sarah said, "Those droplets must be lemonade leaking from inside the pitcher." B. Regina said, "The droplets on the outside of the pitcher are water. They came from the air outside the pitcher." C. Michael said, "I agree that the droplets on the outside of the pitcher are water, but the water comes from the melting ice cubes inside the pitcher." Choose the claim that you most agree with. Support the claim with evidence and reasoning based on what you have learned.
Answer:
it b
Explanation:
The water droplets formed on the surface of the lemonade because Regina said, "The droplets on the outside of the pitcher are water." They came from the air outside the pitcher, which is option B.
What are the different forms of water?Water is present in liquid form, but as the temperature rises, it converts into a gas, which is water vapor. This vapor is present in the atmosphere as a gas, but when it comes into contact with the colder surface, which is the outer surface of the lemonade glass, due to the condensation, the vapor converts into the liquid. When the temperature drops further, the water condenses into a solid, which means ice.
Hence, water droplets formed on the surface of the lemonade because Regina said, "The droplets on the outside of the pitcher are water." They came from the air outside the pitcher, which is option B.

why do the cytoplasmic strands pass nearer to the cell wall than to the sap vacuole
Transport from vacuoles happen through osmosis and diffusion, they lack plasmodesmata required for the passage of cytoplasmic strands.
All cells with a nucleus have cytoplasmic strands, which are spindle-shaped strands. Their major function is to keep the nucleus in place so that it doesn't move from its original position in the cytoplasm. They are additionally known as plamodesmata.When water enters the cell's vacuole but not the nucleus, plant cells experience turgor pressure.Plant cells have channels called plasmodesmata that cross their cell walls to allow for movement and communication. Strands of cytoplasm from a nearby cell communicate through these open channels called plasmodesmata, which are found in plant cell walls.As a result, unlike sap vacuoles which lack communicating channels, cell walls feature plasmodesmata that let cytoplasmic strands move from one cell to another.

What are the differences of cytokinesis in animal and plant cells?
Karyokinesis, or the partition of a nucleus into two daughter nuclei, comes before cytokinesis. All eukaryotes go through cytokinesis in a manner that is remarkably similar. However, it frequently varies between cells with a cell wall, like plant cells, and cells without a cell wall, like animal cells.
Answer: The main difference is the formation of a new cell wall surrounding the daughter cells.
Explanation:
In a plant cell, a cell plate is formed between the two daughter cells.
In animal cells, a cleavage furrow is formed between the two daughter cells.

If this temperature range was between 10 degrees Celsius and 100 degrees Celsius instead, which of the following statements would be true? a) The amount of liquid water would decrease, and the amount of solid water would increase b)The amount of liquid water would increase, and the amount of solid water would decrease c) The amount of liquid water would decrease, and the amount of water vapor would increase
If the temperature range was between 10 degrees Celsius and 100 degrees Celsius instead, the amount of liquid water would decrease, and the amount of solid water would increase. Option A.
Boiling and freezing points of waterWater molecules freeze at temperatures below zero degrees Celsius and boil from a temperature of 100 degrees Celsius and above.
This means that water will be liquid at temperatures between 0 and 100 degrees Celsius.
Now, if the lower boundary is increased - the freezing temperature is increased to 10 degrees Celsius. It means any water below 10 degrees Celsius will be frozen while the temperature range for liquid water has been narrowed.
In other words, the amount of liquid water would decrease, while the amount of frozen or solid water will increase.
