Antibiotics can be used to kill the specific pathogenic bacterium, Mycobacterium tuberculosis, that causes tuberculosis. The appearance of antibiotic-resistant strains has made it more difficult to cure M. tuberculosis infections. These antibiotic-resistant bacteria survive and pass on the genes to their offspring, making the resistant phenotype more common in the population. DNA analysis indicates that the genes for antibiotic resistance are not normally present in bacterial chromosomal DNA. Which of the following statements best explains how the genes for antibiotic resistance can be transmitted between bacteria without the exchange of bacterial chromosomal DNA
a. The antibiotic-resistant bacteria release a hormone that signals neighboring bacteria to become resistant
b. The genes for antibiotic resistance are located on a plasmid that can be passed to neighboring bacteria.
c. The antibiotic-resistant bacteria are the result of bacteria that specifically modify their own chromosomal DNA to neutralize the antibiotics
d. The antibiotic alters the bacterial genome of each bacterium, which results in an antibiotic-resistant population
How do you know your answer is the correct one?
Answer:
b. The genes for antibiotic resistance are located on a plasmid that can be passed to neighboring bacteria.
Explanation:
Conjugation refers to the process where one bacterium known as 'donor' transfers genetic material to another bacterium by direct contact. Conjugation enables bacteria to transfer genes that encode proteins conferring antibiotic resistance to another bacteria by transferring plasmids (i.e., small, extrachromosomal DNA molecules) containing these genes, which is known as horizontal transference. Plasmids that contain multiple antibiotic resistance genes confer Multidrug drug resistance (MDR) and they may severely limit the therapeutic efficacy of treatments against bacteria.
There are different kinds of antibiotics. The statement that best explains how the genes for antibiotic resistance can be transmitted between bacteria without the exchange of bacterial chromosomal DNA is that;
The genes for antibiotic resistance are located on a plasmid that can be passed to neighboring bacteria.Bacteria are known to be able to get antibiotic resistance genes from other bacteria in different ways. It can be gotten when they undergo a simple mating process referred to as "conjugation".
Bacteria are known to transport genetic material such as genes encoding resistance to antibiotics that are resident on plasmids and transposons. This can be transferred from one bacterium to another.

Proteoglycans are part of the extracellular matrix; they provide structure, viscosity and lubrication, and adhesiveness. They are composed of proteins conjugated to carbohydrate components called glycosaminoglycans. The glycosaminoglycan component makes up the majority of the mass of a proteoglycan. Which of these are possible components of glycosaminoglycans
Answer:
This question lacks options, options are: a. beta-D-fructofuranose b. amylose c. uronic acid d. N- acetylglucosamine. The correct answers are c and d.
Explanation:
Glycosaminoglycans are very long, unbranched polysaccharides, made up of repeating units of disaccharides. One of the disaccharides is always an amino sugar, which can be N- acetylglucosamine. The other is uronic acid (it can be iduronic acid or glucuronic acid and is often sulfated at position 2). The amino sugar is usually sulfated and the rest of the sugars have carboxyl groups, which give the structure a negative charge, which attracts a large amount of cations such as sodium. Glycosaminoglycans are often covalently bound to proteins to form proteoglycans. Hyaluronic acid is the only glycosaminoglycan that does not form protein bonds and does not have sulfate groups in its structure.

Which are characteristics of life?
Answer:
All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. When viewed together, these characteristics serve to define life.
Explanation:
Huntington's disease, which causes degeneration of neurons, runs in Mark's family. Huntington's is a heritable, autosomal dominant genetic disease. In an autosomal dominant disease, only one abnormal allele is required to cause the disease in offspring. However, it is possible that not all offspring will receive the abnormal allele from an affected heterozygous parent. Family members that have the disease include Mark's maternal grandfather and Mark's maternal aunts. Mark's maternal grandmother does not have the disease. Because symptoms of Huntington's disease do not appear until later in life, genetic testing is necessary to determine whether a younger individual possesses the allele for the disease. These tests determined that Mark's mother does not carry the allele for Huntington's disease. Mark's paternal aunt suggested that Mark create a pedigree to track the disease in his family. Use the symbols provided to complete the pedigree. Each symbol may be used more than once.
Answer:
The correct answer is - maternal grandmother unaffected, maternal father affected, two maternal aunts affected, mother not affected and paternal side not affected so Mark is also not affected. (check the image)
Explanation:
As we know Mark's paternal grandparents do not have Huntington's disease. If the grandparents are normal the father and paternal aunt of Mark does not carry the disease allele therefore the symbols on the right represent Mark's paternal family.
We also know that the grandfather from the maternal side is affected and maternal aunts also have Huntington's disease, it is found out by the genetic testing that the mother is unaffected which means Mark will be unaffected as well as mother and father both are normal.

List 3 ways that microwaves are beneficial to society
1. It’s a super-fast way to get a (healthy) dinner on the table.
2. Despite what you’ve heard, it’s perfectly safe.
3. It can help migraine sufferers.
1. It’s a super-fast way to get a (healthy) dinner on the table.
For some reason, when most of us think of microwaves, we think of unhealthy (and not-so-tasty) frozen microwavable dinners. But they’re good for so much more than that! Aside from reheating leftovers, you can also use a microwave to make a tender baked potato in just eight to 10 minutes and steam veggies in two minutes with very little cleanup. You can even use it to heat up whole grains and healthy proteins. Not only does it get dinner on the table quickly (no oven preheating or waiting for pressure to release), but it’s especially great this time of year when it’s too hot to even think about turning on the oven. Beyond dinner, I use my microwave regularly to heat up oatmeal in just a few minutes and heat up non-dairy milk for quick lattés.
2. Despite what you’ve heard, it’s perfectly safe.
For several years, I admittedly avoided microwaves because I’d heard myths about dangerous toxins flying through my kitchen and other health claims. Now, I laugh about this.
After doing some digging, I’ve found that many studies confirm that microwaves are more efficient at retaining nutrients than other methods — especially roasting at high temperatures, something most all of us feel safe doing in the oven. Another important fact: Most of us are exposed to more radiation through our cell phones each day than we are with one or two sessions a day of simple microwave use.
Also, no studies to date have found that microwaves cause cancer or any other major disease in humans. The tests that do link microwaves to cancer and neurological issues have only been performed on rats — not humans — which can’t be equally compared and shouldn’t be.
The most important thing to remember when using a microwave is to skip the plastic containers. Old plastic containers could have BPA, and that can leach into our food when the plastic heats. Even if you have new plastic, why not just use glass?
3. It can help migraine sufferers.
I do not suffer from chronic migraines, but I know plenty of people who do — and many of them say that their microwaves are key to helping them manage their pain. See, there are these little bags that can get heated up, and they almost provide instant relief. Yes, you can heat these bags in the oven, but then you have to wait for the oven to heat up and then for the bag to heat up. With a microwave, you just nuke the bag for two minutes and you’re in business
