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.

Explanation:
Answer:
100kcal
Explanation:
The law in energy transfer in the food chain is that only 10% of total energy is transferred.
The food chain between the plankton and starfish follows;
Plankton - Mussels and Oysters - Starfishes - Manta Ray
Plankton being the producer produces 100,000kcal
Mussels/Oysters get 10% of 100,000kcal= 10,000kcal.
Starfish gets 10% of 10,000kcal = 1,000kcal
Manta Ray being the final consumer of starfish gets 10% of 1,000kcal = 100kcal
Age 65 is referred to the age in which a person will normally enroll with an insurance carrier under a part C medicare advantage plan and is therefore denoted as option D.
<h3>What is Insurance?</h3>
This is defined as a form of protection against financial loss or other forms of risks and examples include health, life insurance etc.
Medicare on the other hand is a health insurance program by the American government which helps to cater for individuals who are 65 years old and above and also those with disabilities or certain types of illnesses.
Part C medicare advantage plan are those which are offered by private insurance companies with the eligibility age also being the same as the one run by the government.
This therefore makes option D the most appropriate choice.
The options include the following:

57 degree Celsius or 135 F is the minimum hot holding temperature for baked potatoes.
<u>Explanation:
</u>
Sweet potatoes, baked potatoes, cooked rice, cooked beans, etc are considered as potentially hazardous and hence they must be held at 135 degree F or 57 degree Celsius or hotter.
A restaurant setting food holding and food held before service has lot of differences. Steam tables or cold-holding units are not used in most of the child-care facilities. Cold foods are usually prepared and refrigerated in child-care facilities.
Whenever needed to serve children they are removed from the fridge and then served. The pH and water activity interactions in a food determine whether the food is potentially hazardous or not.
