Typical cervical vertebrae have several features distinct from those typical of thoracic or lumbar vertebrae. The most notable distinction is the presence of one foramen, in each transverse process. These transverse foramina encircle the vertebral arteries and veins.
Answer:
No, because Pneumonia can be transferred from one person to another.
Explanation:
Because humans are the only natural host for S. pneumoniae, our data suggest that the CbpA-mediated recruitment of complement FH may contribute to host tropism of this pathogen. A person can spread the germs that cause pneumonia when he or she coughs and expels the bacterial or viral infections that caused the disease. The droplets containing the virus or bacteria can land on a common surface, such as a table, telephone, or computer. Anyone can get pneumococcal disease, it occurs more frequently in infants, young children, the elderly or in people with serious medical conditions such as chronic lung, heart or kidney disease. Others at risk include alcoholics, diabetics, people with weakened immune systems and those without a spleen.
Have the best day ever! :D
Ok, DNA Polymerase is an enzyme that joins free nucleotides to both existing strands of DNA, which means it isn't D (which is helicase, by the way). They normally work in pairs of two for this function, so it isn't C; this is because if it created a fork, there would only be one needed. Now, concerning A & B, you'll have to be careful. Depending on how A is worded contextually, it could be correct, or it could not. I'm not sure I like the wording "chunks." Which is why I think it's B. Polymerase joins one strand of the "unzipped" DNA to free nucleotides that match it, and these aren't "chunks of DNA." Now, Polymerase is VERY accurate, only making a mistake once every millionth (or billionth?) nucleotide matchup. When it does make a mistake (most of the time), it'll go back and fix it. So I believe the best answer is B, it checks for errors.
Hope this helps!
The correct answer is C. (Ik it's correct because I just answered it)
Answer: 
1.922x10⁻²⁰ Joules
Explanation: <u>Electric</u> <u>Potential</u> <u>Energy</u> (U) is the energy a charged object has due to its location in an electric field and it will only exist with the object is charged.
<u>Voltage</u> or <u>Electric</u> <u>Potential</u> <u>Difference</u> (V) is external work done to move a charge from one point to another in a electric field.
These terms have a relationship, which is given by:
where
q is the charge
Proton is positive and has a charge of 1.6x10⁻¹⁹C.
Unit for potential energy is Joule (J). The relation between mV and J is
1mV = 10⁻³J
Then:
V = 120x10⁻³
V = 0.12
So, for a proton to move from the negative side of a membrane to the positive:
= 1.922 x 10⁻²⁰
Energy necessary to transport a proton from negative side of the membrane to the positive is 1.922 x 10⁻²⁰J.
