Many farmers and gardeners compost their plant and animal waste. The living material naturally decays in compost bins, forming a dirt-like substance that’s rich in nutrients. The next season, farmers use this substance as a natural fertilizer for their crops. A biology student has grown tomato plants for several years. Until now, he used an artificial fertilizer formulated for tomato plants. This fertilizer caused his plants to grow faster and taller than they grew in unfertilized soil. The student wants to know whether using natural compost will cause his tomato plants to grow faster and taller than his artificial fertilizer. Answer the following questions to plan an investigation using the steps of the scientific method and help the student find the answer to his question. Part E How would you conduct your investigation? In your answer, explain your independent and dependent variables.
Answer
no . you should give one plant natural fertilizer and the other artificial fertilizer to decide which works the best
Explanation:
because it is made for tomatoes
Answer:
part E
The dependent variable is the growth rate of the plant. The independent variable is the type of fertilizer used over time. There will be three groups of tomato plants raised from seed: one group will be a control group without any fertilizer, the second group will be planted in soil with artificial fertilizer, and the third group will be planted in soil with compost. The height of the plants will be measured every five days, over a 30-day period.Explanation:
c) Assume that the concentration of the solute molecules varies over time on both sides of the membrane and that the solute molecules continue to pass through the membrane even when the concentration gradient is the reverse of the gradient shown. Describe the environment in and around the cell, as shown in the diagram, and the mechanism of transport of the solute molecules. (3 points)
Answer:
Does the movement of molecules stop when the concentration of a solute is equal on both sides of a membrane?
The concentration of solute molecules on both sides of the membrane will vary over time, and the solute molecules will continue to pass through the membrane even when the concentration gradient is reversed.
The environment in and around the cell is constantly. The diagram shows a cell with a higher concentration of solute molecules on the inside than on the outside. This means that there is a concentration gradient, and the solute molecules will tend to move from the inside of the cell to the outside. This process is called diffusion.
The solute molecules can also move through the membrane by other mechanisms, such as facilitated diffusion and active transport. Facilitated diffusion is a process that uses proteins in the membrane to help the solute molecules move across the membrane. Active transport is a process that requires energy to move the solute molecules across the membrane.
The concentration of solute molecules on both sides of the membrane will continue to change over time. As the solute molecules move from the inside of the cell to the outside, the concentration of solute molecules on the inside of the cell will decrease. This will create a new concentration gradient, and the solute molecules will continue to move from the inside of the cell to the outside.

Which part of an amino acid has the greatest influence on the overall structure of a protein:__________a) the (-NH2) amino groupb) the R groupc) the (-COOH) carboxyl groupd) both A and C
Answer:A - NH2
Explanation:
The part of an amino acid has the greatest influence on the overall structure of a protein is the R group.
The amino acid has the R group and it is simply a term use to state the variable group on each amino acid. The amino acid framework is similar on all amino acidsThe structure of the R-group influences the reactivity of the chemical and solubility of the amino acidConclusively, we can say that the part of an amino acid has the greatest influence on the overall structure of a protein is the R group.

Why are the water weed cells green, but the onion cells are not? Answer in complete sentences. WILL MARK BRAINLIEST!!!
Answer:
Water Weeds have a main extra feature that plant cells have is a cell wall on the outside. So it's mostly made of cellulose, which gives a tough covering on the outside of the cell membrane. And therefore, gives plant cells a distinctive polygonal outline. And the reason why Onion cells aren't green is that cells deep within the structure of plants are not green. Second, not all onion cells are lacking in green color. The bulb of the onion lacks green, but the stem and leaves of the onion plant are green. The reason the bulb is white, and not green is that it has no chlorophyll.
- Hope this helps
Chlorophyll, a distinctive green substance (pigment), fills the chloroplasts. The cell uses this green pigment to absorb light photosynthesis. Cells in onions are not green. No light, hence bacteria don't require chloroplasts.
What does chlorophyll do for your body?Supplement companies assert that chlorophyll has a wide range of benefits, and including ability to increase red blood cells, aid in weight reduction, mend damaged skin, remove toxins, reduce inflammation, and prevent cancer. It's an amazing list, yet only a few of the statements are supported by research. nausea while your digestive system processes the chlorophyll. vomiting, which can harm your teeth by producing stomach acids.
Is it safe to take chlorophyll everyday?An abundance of essential vitamins and minerals may be found in chlorophyll extracts, which also have great pro government, antibacterial, and antioxidant properties. Chlorophyll can be used daily without harm, albeit the recommended quantity varies depending on the type of green you eat. Consuming saffron milk, peppermint tea, clove tea, green tea, protein drinks, green vegetable smoothies, etc fiber-rich juices will drastically reduce you body fat over night.

Why do you think toxicology is an important area of study in veterinary science?
Because some compounds that are not dangerous to humans can be exceedingly harmful to animals, toxicology is crucial in veterinary science.
What is veterinary science?Veterinary science is defined as concerned with preventing the spread of animal diseases to humans as well as the prevention, control, diagnosis, and treatment of diseases impacting the health of domestic and wild animals.
Toxicology is defined as a branch of study that aids in our comprehension of the negative consequences that drugs, events, or chemicals may have on humans, animals, and the environment. The Threshold of Toxicological Concern (TTC) is a notion that refers to the determination of a level of exposure for all chemicals beyond which there would be no appreciable danger to human health, whether or not there are chemical-specific toxicity data.
Thus, because some compounds that are not dangerous to humans can be exceedingly harmful to animals, toxicology is crucial in veterinary science.

Why is it important for cells of multicellular organisms to undergo mitosis? A) mitosis allows for reproduction B)mitosis increases variation within an organism. C) mitosis produces cells that are different from the original dividing cell. D)mitosis produces cells that are identical to the original diving cell
The answer is A mitosis allows for reproduction. This is because during mitosis two identical daughter cells are created which can contribute to an embryo.
Hope this helps ! <3
It is important for cells of multicellular organisms to undergo mitosis because mitosis produces cells that are identical to the original dividing cell. Thus, the right option would be D.
Mitosis involves the division of vegetative cells and it results in daughter cells with the same morphology and genome as the parent cell.
The division of vegetative cells in multicellular organisms will ensure that damaged or dead cells are replaced with cells of similar morphology and genome.
Apart from replacing dead or damaged cells, mitosis also allows multicellular to grow in size by allowing similar cells to spring from existing cells.
