Answer:
Esophagus
Explanation:
In the digestion and absorption of food, the esophagus is the least involved.
It is a part of the digestive system, but all it does is simply pass the food down to the stomach.
The one that is least involved in the mechanical breakdown of food, digestion, or absorption is esophagus. The correct option is d.
Even though it is a vital component of the digestive system, the esophagus plays a much smaller role in the mechanical digestion of food than the other alternatives.
A muscular tube called the esophagus moves food from the mouth to the stomach by a process known as peristalsis, which calls for repetitive muscle contractions.
Its main job is to push food down the digestive tract so that it can travel more easily. Food is mostly mechanically broken down in the mouth while being chewed by the teeth and in the stomach while being churned by muscles.
The majority of digestion and nutrient absorption occurs in the small intestine.
Thus, the correct option is d.

How does the Hardy-Weinberg equation work? With only the information q2=0.0036, how do I find the other numbers? I would greatly appreciate it if someone could help explain this to me, I have been stuck on this for a while. Thank you :))
Answer:
We can find the value of p and q with the following 2 formula.
p + q = 1 and p2 + 2pq + q2 = 1
Explanation:
Here,
q2=0.0036
So, q = [tex]\sqrt{0.0036}[/tex] = 0.06
Using formula, p + q = 1
p = 1 - q
p = 1 - 0.06
p = 0.94
So, based on the value of p and q you can find other required solutions.

Answer:
B i think or C
Explanation:
Because in the way I am thinking it's B, "School cooks should be educated on allergies to peanuts." It makes the most sense
Answer: b
Explanation:
it can't be a since source 2 says "few people recognize..." which contradicts "students know what to do..."
it can't be c because there is no source comparing peanut allergies now vs. past.
it can't be d because you cannot infer this from the given data.
leaving us with b because since a majority of peanut allergies happen at school and not many know how to deal with an event with a peanut allergy, then teaching cooks about peanut allergies will help students in the case of an allergic reaction in school.
