True or false?

1. a scientist who performs an experiment has not predicted what the outcome of the experiment is going to be.
2. the control group and experimental groups are designed to be identical.
3. the independent variable is the variable that the experimenter changes in an experiment.
4. without enzymes, chemical reactions necessary for life would not occur at a rate sufficient to sustain life.
5. membranes are selectively permeable if they allow only certain substances to move across them.
6. water will diffuse out of a cell when the cell is placed in a hypertonic solution.
7. the transport of specific particles down their concentration gradient through a membrane by carrier proteins
is known as facilitated diffusion.
8. in active transport, energy is required to move a substance across a cell membrane.
9. exocytosis the cell rid itself of wastes.

This aquarium exhibits biotic and abiotic factors in an aquatic environment. one of the abiotic factors is

The idea of spontaneous generation was disproved by in a experiment involving jars of meat

Part e - sequence of metabolic processes each of the different cellular metabolic pathways occurs in a specific order. consider aerobic cellular metabolism from the beginning to end. what is the sequential order of the metabolic processes that starts with glucose and results in the production of carbon dioxide, water, and atp? put the following in the correct sequential order. rank from earliest to latest. to rank items as equivalent, overlap them. view available hint(s) acetyl coaglycolysiscitric acid cycle pyruvate finishstartstart background image electron transport chain background image finish background image submit cellular metabolism is often expressed as an equation. this equation puts into perspective, on a general scale, the substances needed to start cellular metabolism and the products that come out of it. the equation represents the overall product yield after every step of cellular metabolism is complete (i.e., glycolysis through the electron transport system). in this part of the tutorial you task will be to put together the equation that represents cellular metabolism. you will also learn the products that result from each metabolic pathway and the role that some these products play in the production of atp.
