Answer:
The answer is A: virus
Explanation:
AIDS (acquired immunodeficiency syndrome) is caused by the late-stage HIV virus; as a manifestation of the patient's great immune compromise, which is practically without defense to resist any infectious attack on the organism.
In the following orbital the lone pair on each N atom is present:
N1: sp3,
N2: p,
N3: p,
N4: sp2,
N5: sp2
Sitagliptin is an anti-diabetic drug used to treat type 2 diabetes and is marketed under the brand names Januvia and others. One carbon atom has no pi bonds, while the first nitrogen atom is linked to two hydrogen atoms. It thus possesses sp3 hybridization.
The second nitrogen atom possesses a single pair of electrons and is bound to three other atoms. It is hence sp2 hybridized. The nitrogen atoms in positions 3, 4, and 5 have sp2 hybridization.
The lone pair of nitrogen in the first nitrogen atom is in the sp3 orbital. The second and third nitrogen atoms' only pair of electrons are in p-orbitals. The fourth and fifth nitrogen atoms' lone pair of electrons are in sp2 orbitals.

Out with the old and in with the new—that's what the respiratory system does, delivering air to the lungs, bringing oxygen into the body, and expelling the carbon dioxide back into the air. Understanding the structure and intricacies of the respiratory system is vital to human anatomy. The respiratory system is made up of more than just the lungs; it also includes your nose, throat, larynx, windpipe, bronchi, alveolar ducts, and respiratory membrane.The function of the respiratory system is to deliver air to the lungs. Oxygen in the air diffuses out of the lungs and into the blood, while carbon dioxide diffuses in the opposite direction, out of the blood and into the lungs. Respiration includes the following processes:
External respiration is the process of gas exchange between the atmosphere and the body tissues. In order to accomplish this task, the following events occur:
1.Pulmonary ventilation is the process of breathing—inspiration (inhaling air) and expiration (exhaling air).
2. Gas transport, carried out by the cardiovascular system, is the process of distributing the oxygen throughout the body and collecting CO 2 and returning it to the lungs.
Internal respiration is the process of gas exchange between the blood, the interstitial fluids (fluids surrounding the cells), and the cells. Inside the cell, cellular respiration generates energy (ATP), using O 2 and glucose and producing waste CO 2.
Answer:
Explanation:
eight out of the 9 trainees prescribed the antibiotics, whereas 7 out of the 12 GPs did so. On the basis of a Bayesian analysis, these results yield reasonable statistical evidence in favor of the notion that experienced GPs are more likely to withstand the pressure to prescribe antibiotics than trainee doctors.
Answer:
A. sharing electrons
Explanation:
A covalent bond consists of the simultaneous attraction of two nuclei for one or more pairs of electrons.
