Answer:
Survival of the Fittest means that animals best suited to a certain area will survive, not that the largest will survive. An example of this is the mouse.
Explanation:
When an animal adapts to live longer, they are adapting to their predators and their environment. For smaller animals, like mice, being big might mean that hawks are able to find them easier, leaving only the small mice to reproduce. I hope this helps!

Hydropower is the renewable resource that supplies which is more electricity to the human population than any other single of renewable resource
Hydropower is the most widely-used by renewable power the source, with the global of hydroelectric installed the capacity exceeding 1,295GW, and accounting for more than the 18% of the world's and total installed power by generation capacity and more than the 54% of the global renewable and power generation capacity.
What is hydropower explain?
Hydropower, or the hydroelectric power, it is a renewable source of energy that is generates power by using the dam or the diversion structure to alter the natural flow of the river or other body of the water.

Answer:
You are interested in obtaining Staphylococcus aureus for a study investigating the prevalence of methicillin-resistant Staphylococcus aureus in the general population. You have received several samples and are ready to start your isolation procedures. Describe the personal protective equipment that would be needed and three different culturing techniques that can be used to obtain organisms to produce pure cultures. State if you use general or selective media and which specific media you would choose. How would you determine if the culture was contaminated? What is the first step you would take if you detected contamination?
Personal Protective equipment needed; No special precautions are necessary when working with methicillin-resistant staphylococcus aureus, staphylococcus aureus is a bio-safety level
Three different culturing media; to include;
- Etest Method
- Disc Diffusion
- Latex Agglutination.
Properly enriched selective media is used.
The most accurate method for identifying Merthicillin-resistant staphylococcus is to test for the presence of mecA gene by PCR.
The best specific media is latex agglutination test and oxacillin salt agar screen.
How to determine if the culture was contaminated;
It can be spotted by the turbidity of the growth medium or the floating branching mycelia, bacteria contamination can be detected under 10× microscope within few days of contamination.
Step to take if contamination is detected;
Biological contamination is a serious issue and being able to correctly identify different types of contamination is an essential first step in ensuring the safety of your culture.
Explanation:
The literature on methicillin susceptible testing is extensive, and often conflicting in recommendations regarding the most important method for routine use. this is partly because the various studies of phenotypic methods have included different strains, which may differ significantly in heterogeneity and behave differently under particular test condition.
The number is different than the number of chromosomes because us humans normally contain 23 pairs of chromosomes which is a total of 46 chromosomes in each cell. A change in the number of chromosomes can cause problems with growth, development, and function of the body systems.
