When a cell membrane is said to be selectively permeable, it means that the cell membrane controls what substances pass in and out through the membrane. This characteristic of cell membranes plays a great role in passive transport. Passive transport is the movement of substances across the cell membrane without any input of energy by the cell. The energy for passive transport comes entirely from kinetic energy that the molecules have.
Keep in mind that your success in Biology will be directly proportional to the amount of effort you invest. You should complete every activity assigned to strengthen your understanding of each concept.
Expectations Do your best effort. Be responsible for your own learning. Believe in your abilities.
Confidence is half the battle. Read all text and supplementary materials as assigned. Try, and then try again. Complete all assignments as assigned. Safety Laboratory safety is important. Although many labs are online, students will be conducting some labs at home.
All students are encouraged to wear protective equipment at all times while conducting labs. Assignments Save all your work to your hard drive or disk and also save it in another location i.
Sometimes things can happen to your computer, and it may be necessary for you to prove that you have completed all assignments.
Cheating and plagiarism is lying and stealing. Read over the key terms. Day 2 Learn about the terminology of biology. This chart shows how the words used in biology are formed.
For today, think about what you already know about living and non-living things. Make a list of what living things have in common. What makes something alive? Then write at least three characteristics of living things with descriptions and examples as shown in the example below. If something is alive it needs a source of energy.
Plants get their energy from the sun. Animals eat plants or other animals. Mushrooms feed on decaying organic material. This is just referencing the source of this assignment. Record your score out of Take off one point for each incomplete section of the assignment.
There are nine things you should have written. Or just create your own. Take notes in an outline form. The title is Characteristics of Life. Then you will write I. All living things are made with one or more cells. Then you would indent and write A.
Read about three characteristics of life. Watch the short video on living things being made up of cells. Watch the short video on unicellular and multi-cellular organisms. Read about examples of single-cell organisms.Lab 1 Osmosis & Diffusion Osmosis Lab Introduction: Cells have kinetic energy.
This causes the molecules of the cell to move around and bump into each other.
Diffusion is one result of this molecular movement. Diffusion is the random movement of molecules from an area of higher concentration to areas of lower concentration.
Osmosis . It is widely apparent that osmosis is an extremely significant process to be studied and was the best choice for our experiment, which provided us with logical results through the study of osmosis process. I'm a lab tech so I LOVE this movie!
If you work in the lab or nursing, etc this movie will be even funnier to you with all the subtle hints, puns, and other jokes. Osmosis Through a Cell membrane of an Egg Joe Lockwood Introduction: When a cell membrane is said to be selectively permeable, it means that the cell membrane controls what substances pass in and out through the membrane.
This characteristic of cell membranes plays a great role in passive transport. Passive transport is the movement . Fulfillment by Amazon (FBA) is a service we offer sellers that lets them store their products in Amazon's fulfillment centers, and we directly pack, ship, and provide customer service for these products.
In some circles, however, opposition to the concept of evolution has persisted to the present. The argument from design has recently been revived by a number of academics with scientific credentials, who maintain that their version of the idea (unlike Paley’s) is soundly supported by both microbiology and mathematics.
