<u>Answer:</u>
<em>An oxygen is not attached to the central carbon atom in an amino acid.</em>
<u>Explanation:</u>
To understand this, we need to look at the <em>simple molecular structure of amino acids.</em> The basic structure of amino acid consists of an amine 
, a carboxyl 
functional groups.
There is also a R-Group for a particular amino acid on the side chain of it. Although oxygen is one of the key constituents of amino acid it is not directly attached with the <em>central carbon atom in an amino acid.</em>
The lactase-persistence mutations are roughly as old as the oldest milk-holding vessels or pots
lactase persistence:
Lactase persistence is an example of natural selection, which can cause some humans to continue the activity of the lactase enzyme in adulthood also.
The hereditary examinations and studies propose that the established mutation related to lactase persistence began a long time back, in populaces that started domesticating and dairy cultivation during the Neolithic age when pastoralist populaces started to utilize milk for their livelihood. As found and studied that “the lactase-persistence mutations are roughly as old as the oldest milk-holding vessels.” The cultural and social activities of dairying and drinking non-human milk gave an environment wherein lactase persistence was favorable. DNA proof demonstrates that mutation in the lactase gene emerged in these populaces around a similar time.

Answer:
Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body's cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP. Carbon dioxide dissolves in water and slowly reacts with water to produce carbonic acid.
Explanation:
Answer:The anesthetic may cause a severe headache, which is treatable."
Explanation:
Spinal anesthesia is a type of anesthesia which is administered locally using a fine needle between L3 and L4 space or L4 and L5 space in order to avoid injury to the spinal cord. This procedure is usually carried out by a trained health personnel such as:
- a nurse anesthetists and
- anesthesiologists
Spinal anaesthesia can be used in different surgical procedures such as Caesarea sections and to manage pain during vaginal delivery in MULTIGRAVID CLIENTS, which are those clients who has been pregnant more than once.
Caesarean section is usually done while the patient is awake with the use of spinal anaesthesia. Therefore it's important to explain any possible side effects from the drug to the patient which includes a severe type of headache called post-spinal headache and it's treatable.
