What is Cell membrane?
Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane.
All cells have a cell membrane, also known as a plasma membrane, which separates the interior of the cell from the external environment.
A semipermeable lipid bilayer makes up the cell membrane. The movement of materials into and out of the cell is controlled by the cell membrane. The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions.
Therefore, Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis.

What is the Operation of the Kidney?The way the kidney is enabled to carry out its' functions are the processes below;
Each human kidney is made up of approximately one million filtering units called nephrons. Now, each nephron includes a filter, called the glomerulus, and a tubule.
Finally, the nephrons work through a two-step process namely;
- The glomerulus filters your blood. Ultrafiltration in glomerulus - smaller molecules filtered out in the glomerulus (e.g. glucose, water, minerals)
- The tubule returns needed substances to your blood and removes wastes.

Did you model weathering, erosion, or both in this lab? Give an example of a step of the lab in which you modeled a process to support your statement. If you say that you did not model one process, describe a way in which you could model that process using the same graham cracker setup.
Modeling of weathering and erosion can be performed in lab.
Lab: Investigate Weathering and ErosionIn this lab, we will be modeling the processes that break down rock using graham crackers as the crust and water and ices erosion agents.
Materials:Graham crackers: at least 2 identical rectangular sectionsPlastic knifeFrostingBowl3 clear glassesEyedropper/medicine dropperWaterIce cube tray or similar freezable containers smaller than a graham crackerAdditional materials as needed for your investigation, such as more graham crackers, hot water, ice, lemon juice, or a drinking strawProcedure of Modeling Weathering and Erosion using graham cracker:
1. Fill the ice cube tray or other tiny containers with 100 drops of water in each of the two or three cells using the eyedropper. Make the water entirely solid by freezing it for however long(for 3-4 hrs.).
2. Insert one graham cracker section into the bowl. To create a ramp-like structure out of the Graham Cracker, place one end on the bowl's lip and the other end at the bottom. To secure the cracker to the side of the bowl, dab some icing on the back of the cracker.
3.Add water to the eyedropper. Hold the dropper at a height of about 1 inch above the cracker's top. the dropper over the cracker in the middle. Apply 100 drips, always aiming for the same area.
4.Keep an eye on what the cracker does. Keep a record of your findings.
5. Pour the water into a glass that is clear after removing the Graham cracker. Make notes about the water, grading its cloudiness among your observations.
6.In the same manner as in step 2, clean and dry the bowl and add a Graham cracker to it. Grab an ice cube and wipe it over the graham cracker until it melts completely.
7.Remove the graham cracker and pour the melted water into the clear glass.
Result:Appearance of water collected after is moved across graham cracker.

A. Describe how the biomass in the bluegill fish trophic level of a biomass pyramid would be
different from the biomass in the aquatic plants trophic level of the same pyramid.
The biomass would be different because aquatic plants are producers while bluegill fishes are consumers.
Pyramid of biomassIn a food chain or food web, the biomass of the population of organisms at the lower trophic levels is usually more than that at the higher trophic level.
Thus, producers tend to have more biomass than primary consumers. Primary consumers tend to have more biomass than secondary consumers.
In the same vein, secondary consumers have more biomass than tertiary consumers.
Bluegill fishes are consumers while aquatic plants are producers. Thus the biomass of aquatic plants would be more than that of bluegill fish.
