In animals, nitrogenous wastes are produced mostly from the catabolism of proteins and nucleic acids.
There are various nitrogenous wastes that are generated by protein catabolism, but the main ones are ammonia and urea. The liver produces ammonia in a healthy person, which is then transformed to urea, a less raw sewage commodity than ammonia.
Once proteins are broken into the amino acids needed for energy, nitrogenous wastes are produced. Ammonia represents the most basic form of nitrogenous waste, constituted from the residual amino acids that occur during protein breakdown.
Proteins are divided into amino acids during catabolic reactions, lipids into fatty acids, and polysaccharides into monosaccharides. These basic elements are then used in anabolic reactions to synthesize molecules.

How does contour plowing in farming help to prevent pollution?A. Contour plowing is used to reduce the amount of fertilizers used.B. Contour plowing is used to make insecticides less toxic.C. Contour plowing is used to reduce erosion and sediment pollution.D. Contour plowing is used to treat pathogens in livestock waste.
Answers
Plowing is a farming practice, that creates as its name says, contour lines, these lines are characteristic because they are placed perpendicular to the slope, for this reason, they are a method used to prevent erosion and retain water.
With this information in hand, we can see that option A is not correct because the use of plowing is related to soil loss and not to soil richness per se. Option B is not correct either because the use of insecticides is more related to the type of crop and surrounding vegetation cover. Option C in this case is the correct answer, it is used to reduce erosion and sediment pollution because helps retain soil. Finally, option D is not correct because this method is not related to livestock.

Answers
Plutonic or intrusive igneous rocks form when it cools below the Earth's surface.
Igneous rocks form when it cools on the Earth's surface.
How is the rock formation process?They originate from the solidification of magma inside the Earth's crust or when lava comes out of the mantle, through a volcanic eruption. When magma cools slowly inside the crust, turning into rock, a process called intrusion occurs.
With this information, we can conclude that Igneous rock or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic and Intrusive, or plutonic, igneous rock forms when magma remains inside the Earth's crust where it cools and solidifies in chambers within pre-existing rock.

explain the role of meiosis in sexual reproduction and evolution, distinguishing between somatic and germ-line cells (gametes).
Answers
Meiosis, which takes place during gamete production, results in cells that have half as many chromosomes as usual. Meiosis prevents reduced division from causing the number of chromosomes to skyrocket.
Meiosis stops a growth in the number of chromosomes by blocking decrease division. Somatic cells are any cells in a multicellular organism that are not germ-line cells. Gametes are haploid reproductive cells that make up the germ line (eggs and sperm). unite to produce a zygote during fertilization.Meiosis is a type of cell division that results in the production of four gamete cells and a 50% reduction in the number of chromosomes in the parent cell.

Answer:
The correct answer is "building gradients of substances across the outer cell membrane"
Explanation:
Building gradients of substances across the outer cell membrane is a form of diffusion in which substances move across cellular membranes based on there independent gradient. This form of movement is a type of passive transport because it does not require the use of ATP for transport. The building gradients of substances across the outer cell membrane requires diffusion and does not require the use of ATP.
Movement of vesicles along cytoskeletal tracks requires individual vesicles to be transported by there respective motor proteins along the cytoskeletal tracks. These motor proteins require ATP to move these vesicles. Also, the phosphorylation of a motor protein in the cytosol requires one phosphorus molecules from ATP.
Transport of protons (H+) from low concentration in the mitochondrial matrix to high concentration in the mitochondrial intermembrane space is a description of the "hydrogen pump" that occurs in the electron transport chain. When hydrogen ion pump occurs, the hydrogen ion gets flown back through a ATP molecule.
Sometimes you might not be able to see a new substance forming, so be on the lookout for evidence that a chemical change has occurred. A change in smell and color can indicate that a new substance has formed. For example, caramelized onions have a very different smell than raw onions. They have a darker color, too. Other physical properties about the onions change during caramelization, including their texture. The formation of bubbles can be evidence of a chemical change, but only if they indicate that a new gas is formed. If you heat a pot of water, the water will begin to boil. Those bubbles are not any new substance forming. They’re just the same water you started with changing state from liquid to gas.
Based on this passage, if you cannot see that a new substance has formed,
A
only a physical change could have occurred.
B
a chemical change might have occurred.
C
a change in state has always occurred.
D
no change could have occurred.
Answers
it is possible for a chemical change to occur even if there is no visible evidence of a new substance forming.
What visual signs of chemical alteration exist?A change in colour and the appearance of bubbles are two indications of a chemical shift. The five elements of chemical change are: colour change, precipitate or gas production, gas formation, odour change, and temperature change.
If there is no chemical change, may a physical change still happen?Physical changes can be brought about by physical actions like adjusting the temperature or pressure. You melted the ice, but nothing happened chemically. Water molecules are still molecules of water.

The layers are formed due to difference of density of solutions.
The main cause of the order of the layers is the difference of weight and density of different liquids in the container. The liquids that has more weight means higher density will sink below the liquids that has less weight means lower density so due to difference in their density corn syrup is located at the bottom due to higher density and rubbing alcohol is present at the top of the container due to lower density.
https://brainly.com/question/24277427
What caused the order of the layers can be attributed to the densities of the liquids.
The density of a substance is an indication of how heavy the substance is in relation to its volume. Mathematically, it is given as mass/volume.Hence, a liquid with a higher density will always be at the bottom of a liquid with a lower density provided that both of them are of the same volume.In order words, immiscible liquids poured together in the same container will separate out according to their densities - starting with the highest density liquid occupying the bottom with the lowest density liquid staying topmost.
