The male contributes the sperm and the female contributes the egg or ovum. Then they meet in the fallopian tube and becomes a zygote.
Answer: Homeostasis
Explanation: One way that a cell maintains homeostasis is by controlling the movement of substances across the cell membrane. The lipid bilayer is selectively permeable to small, nonpolar substances. Proteins in the cell membrane include cell-surface markers, receptor proteins, enzymes, and transport proteins.
Answer:
To determine the effect of toxin binding, you perform a Competitive Binding Experiment
Explanation:
Competitive binding experiments are very relevant when matters relating to cellular and or molecular toxicity are concerned.
They are used to determine the binding of a single concentration of labeled ligand in the presence of various concentrations of unlabeled ligand.
They are important because:
1. Validate a direct binding assay
2. Confirm whether or not a drug binds to the receptor
3. determine and explore how low-affinity drugs and receptors interact and it's resultant effects
