Answer:
B
Explanation:
The only difference between the speed and the velocity is that the velocity tell us about magnitude and direction but speed tell us about magnitude only. Hence, the correct option is,
Answer:
d. The normal pH of human blood is already in the alkaline range.
Explanation:
The blood has an average pH between 7.35 and 7.45. Also, in blood there are some natural buffers that allows to maintain this pH does not matter the kind of food or substances that enter to our body.
If for any process the pH decreases a little bit, the body starts a process to recover the natural pH of the blood.

Answer:
If a strand of DNA contains the bases adenine, cytosine, cytosine and guanine the order of the bases on the opposite strand is thymine, guanine, guanine and cytosine.
Explanation:
DNA contains a double strand, each of which contains a specific sequence of bases —adenine, thymine, cytosine and guanine— whose order determines the genetic information stored in this nucleic acid.
The sequence of bases on one DNA strand is complementary on the other strand, taking into account the complementarity of bases, i.e. the purines adenine and guanine are complemented by the pyrimidines thymine and cytosine, respectively:
A = T
G ≡ C
<u>So that the sequence A - C - C - G of one chain is complemented by the sequence T - G - G - C of the other</u>.
<em> Taking into account the above information, the other options can be discarded, as they do not comply with the complementarity of bases in the DNA.</em>
Answer:
Pneumonia may be defined as the medical condition in which the inflammation might occur in the lungs due to which the fluid might accumulate in the lungs. The infection might occur by the Streptococcus penumoniae bacteria.
The most likely diagnosis of this patient can be influenza. The symptoms shown by the patient like cough, fever, headache, lung pain is more common in influenza. The diagnosis can be based on the symptoms shown by the patient and no presence of the Streptococcal infection. This conditions can be worsened if the pneumonia follow the harsh influenza and this secondary infection must be monitored. The treatment that can be preferred in this patient bed rest, anti pyretic medicines and proper body fluids.
