In 2012, a research team at the University of Guelph randomly selected 44 herbal products off the shelves in Canada and the U.S.

and started comparing them to the plant DNA in their databank. They found that ____ percent of the products contained ingredients not listed on their labels. Even more astonishingly, ________ proved to be outright fakes. More recently, Eric Schneiderman ordered up his own tests of herbal supplements purchased from four major chains — Walmart, Walgreens, Target and GNC — from various locations around New York State. He found that only _____ percent of products tested had DNA evidence that they contained the product listed on the label. They found _______ DNA, _______DNA, ________ and other things, but not the product that was on the labels. The Institute of Medicine recommends avoiding getting above 4,000 IUs of _______ daily because that could be associated with adverse events: _____ in the urine, which can be associated with ________; high blood _______, calcium in the _________; vascular ____________; as well as __________ calcification. And there are now studies that show a U-shaped curve — that those who have _____ as well as ______blood levels of _________ have higher risk of cardiovascular disease, as well as all-cause mortality. So we can’t assume that more is necessarily better. The FDA division in charge of the supplement industry is ______, with _____ employees. They target companies they consider the most risky, but agree the problem remains much bigger than that. Because of the targeting and because of, traditionally, the way the supplement industry has developed over time, a ______ proportion of inspections of dietary supplements have substantial problems compared to other categories that FDA regulates. To many, supplements may look like __________, but there is a big difference. _________ have to prove their products are safe and effective before putting them on the market. Those who make _______ don’t, not unless they’re introducing __________ that’s never been marketed before.

Vinvika [58]

Isotopes are variants of a particular chemical element which differ in neutron number (neutral particle)and all isotopes of a given element have the same number of protons (positive particle) in each atom.So isotope B of the sodium will have 11 protons, 11 electrons but it may have a wide range in its number of neutrons.

Refer to the following five terms to answer the following questions. Choose the most appropriate term for each phrase. Each term
soldi70 [24.7K]

Answer: 3. C. mitochondrion

Explanation:

Mitochondrion in a cell is defined as the powerhouse of the cell which provide energy to the whole cell.

A mitochondrion is has a membranous layer and bean-shaped organelle that is the “energy transformer” of the cell. They contibute to the  biochemical processes of the cell called cellular respiration. They works as a digestive system which takes nutrients, breaks them into several energy rich molecules for the cell.

Hence, the correct answer is 3. C. "mitochondrion".

Molecule 1 has the nitrogenous base sequence TCA AGT. Which set of bases in Molecule 2 can bond to that sequence in a complement
serious [3.7K]

Complete question:

Molecule 1 has the nitrogenous base sequence TCA AGT. Which set of bases in Molecule 2 can bond to that sequence in a complementary way?

a. UCAAGU

B. AGTACA

C. AGUUCA

D. UCAATA

Answer:

C. AGUUCA

Explanation:

DNA template strand and the corresponding RNA have complementary sequences. Adenine in the DNA template strand pairs with "uracil" base of RNA while cytosine pairs with its "guanine" base. Similarly, thymine base in DNA template strand pairs with "adenine" base in the RNA. This occurs since RNA does not have a thymine base. RNA has uracil base instead. Therefore, the molecule 1 with sequence  TCA AGT would bind to the molecule 2 with the " AGU UCA" sequence.  

Molecule 1: DNA template:  TCA AGT  

Molecule 2: mRNA:              AGUUCA

Which of the following is true of retroviruses? (3 points)
Nikitich [7]

Answer:

Explanation:

A retrovirus is an RNA virus that is duplicated in a host cell using the reverse transcriptase enzyme to produce DNA from its RNA genome. The DNA is then incorporated into the host’s genome by an integrase enzyme. The virus thereafter replicates as part of the host cell’s DNA. Retroviruses are enveloped viruses that belong to the viral family Retroviridae. A special variant of retroviruses are endogenous retroviruses, which are integrated into the genome of the host and inherited across generations. Endogenous retroviruses are a type of transposon.
