Answer :
Vinegar is a weak acid. This is used to make a naked egg. When an egg is added in the vinegar for one day / 24 hrs, it reacts with the eggshell. The calcium carbonate shell gets dissolve.
Then an egg without shell is formed and the size of the egg does not change. The calcium carbonate reacts with acetic acid and forms carbon dioxide.
When the shell-less egg is kept in the vinegar for 48 hrs i.e. 2 days again, the water content in it enters into the eggs through the membrane. Then the egg gets somewhat bigger.
Otherwise, for 24 hrs, vinegar is acting like an isotonic solution and only dissolves the shell. This experiment would be done for showing the osmosis process through the cell membrane.
Habitat: Coyotes are able to easily adapt to different habitats. They can be found living anywhere from the Sonoran Desert to large, populated cities.
Food: Coyotes will eat nearly anything. They hunt rabbits, rodents, frogs, fish, and even deer. they also eat insects, snakes, fruit, and grass.
Reproductive Process: Reproduction<span> in the </span>coyote<span> is a very intricate </span>process<span>, as females are completely infertile for ten months out of the year, and males are sterile for eight. The </span>process<span> begins with several males vying for the attention of a single female.</span> In spring, females den and give birth to litters of three to twelve pups. Both parents feed and protect their young and their territory.
Human and Environmental Challenges: Coyotes face many challenges. They are often hunted by other larger animals. Humans also hunt them when they are interfering with their crops or livestock.
Migration pattern: <span>According to a study, coyotes migrated eastward via two main route: one that went through the northern United States, and one that went through the south. Oddly enough, the Northern and Southern coyotes seemed to meet midway</span>
As the wolf population increases, the need for food will increase, causing the wolves to hunt more hares, making the hare population decrease.
Answer: Bacteria gain resistance to drugs because of mutations (permanent and random changes to their DNA) which means they have changed DNA coding, giving them the ability to resist the drug fighting them off. As a result, they survive and reproduce. Over time, more and more bacteria are generated as the DNA code for resistance is passed on over generations. This results in bacteria having the ability to resist drugs. This is particularly prevalent with antibiotics.
The first responsibility of the surgeon is notify the surgeon and go over the preoperative skin antiseptic choice.
Preoperative Skin- An excellent way to reduce surgery site infections is preoperative skin preparation (SSI). The two most often used antiseptics are povidone iodine (PV-I) and alcoholic chlorhexidine (CHG). Their effectiveness in lowering the normal bacterial skin flora after clean orthopedic surgery is the focus of this meta-analysis.
Antiseptic- An antiseptic is a substance that inhibits or stops the development of microorganisms on the body's outside surfaces, hence assisting in the prevention of illnesses.
Microorganism- A living thing that can only be observed under a microscope. Protozoa, algae, fungus, and bacteria are all examples of microorganisms.
