A) Soil pH is a characteristic that describes the relative acidity or alkalinity of the soil of the Soils are considered acidic below a pH of 5, and very acidic below a pH of 4. Conversely, soils are considered alkaline above a pH of 7.5 and very alkaline above a pH of 8
B) While there's logic in that, dogs don't just love treats, they also love new treats. Most dogs get very excited at the sight of a new treat even if the old one is still their favorite. Keep giving them the old ones as well if they prefer it, but also add a little diversity of a they be grateful
C) the important meeting one whose outcome affects you and your team the after it happens. When you’re overlooked for a meeting it feels bad personally and professionally
D) the long term running changes your vascular system; your heart size grows, the heartbeat rate decreases and your arteries widen. They may get harder with the build up of plaque as the studies indicate, but it's not clear that that's a bad thing
The answer is T A A C G T.
Replication is a process in which DNA molecule is copied, and thereby two identical DNA molecules are produced. Complementarity is achieved through interactions between nucleobases. In the DNA, base complements are adenine - thymine (A-T) and guanine - cytosine (G-C).
So, free nucleotides will add in the following order <span>T A A C G T:

Answer:
Yes, swollen lymph nodes are more common than some might think.
Explanation:
The medical terms for swollen lymph nodes are adenopathy or lymphadenopathy.
Lymph nodes play a vital role in fighting off sickness in the body. They act as a filter, trapping bacteria and viruses before they can spread too far.
Lymph nodes <em>typically</em> swell up as a response to bacteria or viruses. Though cancer can be a factor in swelling, it is very rare. Most commonly they are felt right below the corner of the jaw, in the neck. Yet, they are not only in the neck; they are all throughout the body. When they are swollen, they might feel tender or even painful.
Half life formula
The number of unstable nuclei remaining after time t can be determined according to this equation:
N(t) = N(0) * 0.5^(t/T)
where:
N(t) is the remaining quantity of a substance after time t has elapsed.
N(0) is the initial quantity of this substance.
T is the half-life.
It is also possible to determine the remaining quantity of a substance using a few other parameters:
N(t) = N(0) * e^(-t/τ)
N(t) = N(0) * e^(-λt)
τ is the mean lifetime - the average amount of time a nucleus remains intact.
λ is the decay constant (rate of decay).
All three of the parameters characterizing a substance's radioactivity are related in the following way:
T = ln(2)/λ = ln(2)*τ
How to calculate the half life
Determine the initial amount of a substance. For example, N(0) = 2.5 kg.
Determine the final amount of a substance - for instance, N(t) = 2.1 kg.
Measure how long it took for that amount of material to decay. In our experiment, we observed that it took 5 minutes.
Input these values into our half life calculator. It will compute a result for you instantaneously - in this case, the half life is equal to 19.88 minutes.
If you are not certain that our calculator returned the correct result, you can always check it using the half life formula.
Answer:
Obtain specimen before antibiotics are given.
Explanation:
Antibiotics may be defined as the chemicals given to kill or restrict the growth of the bacterial infection. The antibiotics are not available for virus as they can change their DNA.
The sensitivity results can be accurate if the nurse is able to ensure the successful culture of the antibiotics. Throat culture specimen is taken from the pharyngeal area. The aseptic technique can be used by the nurse for obtaining the blood and urine specimen.
Thus, the answer is obtain specimen before antibiotics are given.
