Answer:
Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.
hope this helps :)
can i have a brainilist pls
Answer:
i would say selection because this is not instinct thus not natural
1. Antibiotic resistance can cause global epidemics of diseases hence casing health disasters that result in high mortality and morbidity in the human population. This is because the current drugs in the market against the diseases will not be effective anymore in its control.
2. One is the misuse of antibiotics by people who self-prescribe these drugs over the counter and people who fail to complete their drug prescription when they start feeling better. The other is the overuse of the antibiotics in livestock and poultry farming.
3. One is the total ban of the use of antibiotics in poultry and livestock farming. The other is through campaigns to urge the proper use of antibiotics by people. The third is improving infection control mechanisms and system in healthcare settings.
4. People can maintain proper hygiene and sanitation using soap and hence will not require to use antibiotics to eradicate diseases which are brought about by poor sanitation. Patients should complete the full dosage of prescribed antibiotics even when they start feeling better before completion of the drugs.
5. The best way of dealing with antibiotic resistance is maintaining hygiene and sanitation. This reduces the need for use of antibiotics most of which are used against diseases that are preventable just by ensuring that the environment is clean. Increased use of antibiotics induces high rates of mutations in bacteria hence higher chances of developing resistant strains.

a. Does putting the yeast on salt cause the beneficial mutation? Why or why not?
When the logarithmic growth of cells is interrupted by exposure to a 0.5 to 2 Molar salt solution the aueous solution consisting of KCl, NH4Cl, NaCl, MgCl2 are basically mutagenic in yeast .
Stationary phase cells are not mutated by the treatment.
b. If you screened your mutagenized yeast cell population on caffeine (another substance that normally kills them), could you find caffeine tolerant ones? (assume there is the potential for genetic resistance to caffeine).
For normal tolerance to caffiene the sty1 and pap 1 pathways are not necessary, but generally only sty1 is activated by mutation hence making yeast sensitive for caffiene.
