HELP!!! WILL GIVE MAX POINTS!! Doing a Lab Report on Natural Selection about beans. For example 20 dark red beans and 35 light red beans (kidney beans) Sample Response: When the volcano erupted, the dark red walking beans were easier to see. Thus, more dark red beans were eaten during days four, five, and six. If the pollution continued, there would be fewer and fewer dark red walking beans over time.
Questions being asked are:
1. What is the purpose of the lab?
2. What is your hypothesis for this experiment?
3. What methods are you using to test this hypothesis? (Outline the steps of the procedure in full sentences.)
4. 4. What graphs would clearly represent the trends in your data?
Your Student Guide includes information on which graphs to construct. Each graph should have the following items:
a. An appropriate title
b. Appropriate labels for each axis
c. An appropriate scale for each axis
d. The correct units for the data
Complete a rough sketch of each graph.
5. What do the data in your graphs tell you? (Explain in one or two sentences what trend is shown in each of your graphs.)
6. What does the data tell you about your hypothesis? (State how your hypothesis is either supported OR refuted by the data)
7. How does the data support your claim above? (Explain your statement above. Be sure to refer to specific pieces of data from your experiment that supports your argument)
8. 8. If you could repeat the experiment and make it better, what would you do differently and why?
There are always ways that experiments can be improved. Now that you are a veteran of this experiment and have experience with the procedure, offer some advice to the next scientist about what you suggest and why.
Answer:
During the days four through six the population of the dark red beans changed. The change was negative meaning that there was less dark red beans that light red beans. This happened because it was harder to see the light red beans because the color of the air changed. In result of that the zocco ate mostly dark red beans.

Describe the path of a phosphorous atom through four parts of the phosphorous cycle. Be sure to explain the processes involved in the transfers. Note when a form of phosphorous is available to plants. (Will mark brainliest)
Answer: One of the ways the path of a phosphorous atom starts is in a rock containing phosphate. The rock weathers, so that a phosphate ion enters the soil. A plant takes up the phosphate ion and incorporates it into a DNA molecule in a pollen grain. The grain falls back to the ground and decomposes, converting the atom back into phosphate through mineralization. The phosphate ion then leaches into the groundwater, leaving the soil.
Explanation: Plato/ Edmentum
Phosphorus moves in a cycle through rocks, water, soil and sediments, and organisms. Over time, rain and weathering cause rocks to release phosphate ions and other minerals.
This inorganic phosphate is then distributed in soils and water. Plants take up inorganic phosphate from the soil.
How does phosphorus enter the phosphorus cycle?
Phosphorus enters the atmosphere from volcanic aerosols. As this aerosol precipitates on earth, it enters terrestrial food webs. Some of the phosphorus from terrestrial food webs dissolves in streams and lakes, and the remainder enters the soil. Another source of phosphorus is fertilizers.

What are some benefits of farming for the society/environment?
Answer:
Pasture and cropland occupy around 50 percent of the Earth's habitable land and provide habitat and food for a multitude of species. When agricultural operations are sustainably managed, they can preserve and restore critical habitats, help protect watersheds, and improve soil health and water quality. in addition to preserving the earth's natural resources, sustainable agriculture benefits the environment through helping maintain soil quality, reducing erosion, and preserving water. Plants and trees in agricultural systems help to retain and add water to underground aquifers. ... Together, they act as an important buffer in the landscape, preventing flooding, reducing water pollution from agricultural runoff and preventing erosion, while providing us with nutritious food at the same time. Farming creates opportunities to lift people out of poverty in developing nations. Over 60 percent of the world's working poor works in agriculture. Farming creates more jobs, beginning with farmers, and continuing with farm equipment makers, food processing plants, transportation, infrastructure and manufacturing.
Explanation:
The benefits are:
early agriculture
Morden agriculture's opportunity
Development in farming sustainability
Farmers improve their communities

Explanation:
There are two stages to photosynthesis: Reactions of light and darkness. Light-Reaction takes place in thylakoid membrane.
What is Light-Reaction takes place during Photosynthesis?Autotrophic plants produce their own food through a process called photosynthesis. Sunlight, chlorophyll, CO2, and water are four crucial components needed for this process. It is a response that is light dependent.
In plants and some other creatures, a process known as the "Dark Reaction" harnesses the energy from the sun to change carbon dioxide and water into glucose (a sugar) and oxygen.
Therefore, a sequence of chemical events known as the "Light Reaction of Photosynthesis" are what is needed for the pigment found in leaves, such as chlorophyll, to transform light energy into chemical energy in the form of ATP and NADPH.

How does your body respond to an increase in the waste products of energy production
Answer:
Energy is delivered to the body through the foods we eat and liquids we drink. Foods contain a lot of stored chemical energy; when you eat, your body breaks down these foods into smaller components and absorbs them to use as fuel. Energy comes from the three main nutrients carbohydrates, protein, and fats, with carbohydrates being the most important energy source. In cases where carbohydrates have been depleted, the body can utilise protein and fats for energy. Your metabolism is the chemical reactions in the body’s cells that change this food into energy.
Most of the energy the body needs is for being at rest, known as the Basal Metabolism. This is the minimum amount of energy the body requires to maintain its vital functions such as breathing, circulation and organ functions. The rate at which energy is utilised for such functions is known as the Basal Metabolic Rate (BMR) and varies based on genetics, sex, age, height and weight. Your BMR drops as you get older because muscle mass decreases.
Optimal energy metabolism requires getting sufficient nutrients from our foods, otherwise our energy metabolism underperforms and we feel tired and sluggish. All foods give you energy and some foods in particular help increase your energy levels, such as bananas (excellent source of carbohydrates, potassium and vitamin B6), fatty fish like salmon or tuna (good source of protein, fatty acids and B vitamins), brown rice (source of fibre, vitamins and minerals), and eggs (source of protein). There are actually many foods that provide an abundant amount of energy, particularly those packed with carbohydrates for available energy, fibre or protein for a slow release of energy and essential vitamins, minerals and antioxidants.
Foods are metabolised at a cellular level to make ATP (Adenosine Triphosphate)
by a process known as cellular respiration. It is this chemical ATP that the cell uses for energy for many cellular processes including muscle contraction and cell division. This process requires oxygen and is called aerobic respiration.
Glucose + Oxygen → Carbon dioxide + Water + Energy (as ATP)
Initially, large food macromolecules are broken down by enzymes into simple subunits in the process known as digestion. Proteins are broken down into amino acids, polysaccharides into sugars, and fats into fatty acids and glycerol—through the action of specific enzymes. Following this process, the smaller subunit molecules then have to enter the cells of the body. They firstly enter the cytosol (the aqueous part of the cytoplasm of a cell) where the cellular respiration process begins.

14. Which of the following occurs during the electron transport chain?
a. the formation of ATP by oxidative phosphorylation
b. the formation of water
c. a concentration gradient of protons
d. all of the above
Answer:
All
Explanation:
The electron transport chain is a series of four protein complexes that couple redox reactions, creating an electrochemical gradient that leads to the creation of ATP in a complete system named oxidative phosphorylation. It occurs in mitochondria in both cellular respiration and photosynthesis.
Answer:
D
Explanation:
ATP is created in the ETC
Water is formed as a by product
The concentration gradient is what fuels the ETC. Protons (H+ ions) move across the membrane to create energy.
