Question 2
Taking antibiotics for viral infections has no positive impact on individual health because
viruses are not killed by antibiotics. What negative impact does the unnecessary use of
antibiotics have on public health?
Answer:
Antibiotic Resistance
Explanation:
Antibiotic Resistance is when bacteria mutates or adapts to become resistant to antibiotics, wether by protecting the bacteria itself or limiting how the antibiotics can effect the body. This antibiotic Resistance can happen from using too many antibiotics, or using antibiotics but not having a high enough dose (so all the bacteria isn't killed). This can cause much more serious infections, like pneumonia and meningitis, to happen, and they can last longer, as they may not immediately respond to treatment. These can also spread to people who don't have a problem with antibiotic Resistance, but will get the antibiotic resistance bacteria which can mess with the other bacteria in their body, making them antibiotic resistant, which turns into a cycle of spreading bacteria and becoming resistant.

Answer:
almost all of our food contain them .so answer is option C
Explanation:
Almost all of our foods contain food spoilage microorganisms.
What are food spoilage microorganisms?When there is an unpleasant change in the meal's usual state, food spoiling develops. This could be a modification to the way the meal looks, feels, tastes, or smells. The usual culprits for spoilage are bacteria, molds, or yeasts. The appearance of green fuzzy spots on a piece of bread is a classic sign of rotting.The most common bacteria linked to spoiling include Lactobacillus spp., Carnobacterium spp., Lactobacillus spp., and Brochothrix thermophacta. The primary spoilage organisms in cultured foods like yogurt, sour cream, and buttermilk are yeasts and molds. Butter can become spoiled by yeasts, molds, and Pseudomonas bacteria. Butter is more prone to surface mold growth than bacterial deterioration because of its high fat content and low water activity.learn more about food spoilage microorganisms here: https://brainly.com/question/17966536

what is the difference between mitosis and cytokenisis
Answer:
Mitosis refers to the division of a cell's nucleus into two. Cytokinesis refers to the further division of the cytoplasm of the cell, forming two daughter cells.
Explanation: I hope this helps :)
Explanation:
The Mitosis Phases
Mitosis itself is the division of the nuclei into daughter nuclei. It includes five phases of its own.
Prophase: Here, chromosomes become more condensed in the nucleus, and the nuclear membrane dissolves. The mitotic spindle forms from the centrioles, which have split and moved to opposite poles (sides) of the cell. This spindle is made of proteins in the form of microtubules.
Prometaphase: In this step, the chromosomes migrate toward the center of the cell. They are propelled by the mitotic spindle apparatus attached at the centromeres that joins sister chromatids. They begin to approach a line perpendicular to the direction they are moving, through their centromeres, called the metaphase plate.
Metaphase: In this step, chromatids align precisely along the metaphase plate via their centromeres, with one sister chromatid on each side of the metaphase plate.
Anaphase: In this step, the sister chromatids are pulled to opposite poles of the cell, releasing from each other at the centromere. The spindle fibers, again, are responsible for this motion.
Telophase: In this step, daughter nuclear membranes form around the newly formed daughter nuclei. At this point, chromatids are unpaired, as this generation's chromosome replication has yet to start. This is because cell division is not quite complete.
Cytokinesis
To define cytokinesis as a stand-alone phase, the difference between telophase and cytokinesis is best imagined by thinking of telophase ending the instant both daughter nuclear membranes are completely formed. Cytokinesis starts with a "pinching inward" from the top and the bottom of the cell, with one daughter nucleus on each side.
This "pinching" results from the formation of a protein structure called the contractile ring, which runs around the widest part of the cell under the membrane. When this shrinks inward, it pulls the membrane tighter along with it until the cell halves are completely separated by the now-finished "pinch."

If a sewage treatment plant malfunctions or if low-income areas lack sanitary waste disposal, raw sewage can be introduced into surface waterways. Describe one potential environmental problem or one potential human health problem that can result from the presence of raw sewage in surface waters.
The more significant problem is that raw sewage causes eutrophication, which is an expansion in the concentration of chemical elements needed for life. The natural systems on steroids. The nitrates, phosphates and other organic matter found in human waste serves as a food for algae and bacteria.
What are the effects of sewage on human health?Sewage and wastewater contain bacteria, fungi, parasites, and viruses that can induce intestinal, lung, and other infections. Bacteria may cause diarrhea, fever, cramps, and vomiting, headache, weakness, or loss of appetite.

What will the overall charge of an atom be if it has more protons than electrons?
A:neutrally charged
B:negatively charged
C:ionically charged
D:positively charged
Answer:
D
Explanation:
A: Neutrally charged atoms have the same number of protons and electrons.
B: Negatively charged atoms have more electrons than protons. These are also called anions.
C: ironically charged is a molecule that has a charge so a cation or an anion. This option isn't correct becuase it's not specific enough for the question. An ion can be positively charged (cation) or negatively charged (anion).

A real case where RFLP was used.
Answer:
Alec Jeffreys and the Pitchfork murder case: the origins of DNA profiling
British geneticist Alec Jeffreys began working in 1977 on a technique that could identify individuals through samples of their DNA. In 1984, he and colleagues devised a way to use a newly discovered property of DNA, isolated areas of great variability between individuals called restriction fragment length polymorphisms (RFLP), for forensic identification—the original DNA fingerprint.
In 1986, police asked Jeffreys for help in finding a man who had raped and killed two girls. DNA tests exonerated the primary suspect. Through a genetic dragnet, police found the perpetrator, Colin Pitchfork, who gave himself away when he asked a friend for a substitute blood sample.
Within a year, genetic fingerprinting was making the unique molecular structures of victims and suspects visible in criminal investigations around the world. Today, RFLP-based DNA analysis is being supplanted by newer techniques of genetic identification.

Cactus finches have long, pointed beaks. Say the only source of food for Cactus finches is cactus flowers. If a plant disease killed a large portion of the cacti on the Galapagos islands, how would the population of Cactus finches change
The population of the Cactus finches suddenly experiences a decline when a large portion of the cacti on the Galapagos islands was killed by a disease.
What do you mean by Population?A population may be defined as the number of individuals of the same species living in a particular area at a given time.
Cactus finches only depend on the cactus flower as a food source, and if these flowers were killed by a disease, the cactus finches do not get enough food to survive and reproduce, hence their population may fall rapidly.
