How much memory can a two-year-old child’s brain hold?

The DNA contained within the cells of the body is damaged.

The ‘random events’ theory states that external and spontaneous mutations are responsible for the damage to the DNA that is contained within the cells of the body. Over a period of time, this damage makes the repair process inefficient and may also lead to cancerous cell production.

The right answer is: C. One form of a gene.

The human body consists of 23 pairs of chromosomes. Each chromosome contains many information in the form of genes that express the hereditary characteristics of an individual.

Each gene has two alleles, one from the genetic information of the father, the other from that of the mother. If the two alleles of the individual are identical, the characteristic resulting from this allele will be expressed. If, on the other hand, they are different, the so-called dominant allele will be imposed on the other recessive allele, and it is this dominant allele which will give its characteristic to the individual.

By way of example, the color of the eyes: if a child inherits a "brown" allele and a "blue" allele, he will have brown eyes, since the brown allele is dominant in relation to the allele blue that is recessive.

The correct answer is

B. chromosomes of the same type

Explanation:

An allele is an alternative form of a gene which is situated at a specific position on a specific chromosome. These DNA codes describe distinct traits that can be passed on from parents to their offspring through sexual reproduction.  “Alternative form of the gene” means that there is difference in the genetic content between the two genes of a simple Mendelian trait.

Answer: jejunostomy

Explanation:

jejunostomy = a surgically implanted tube from the small intestine to the outside of the body.

The wrong answer is "gastrostomy" which is placed from the stomach to the outside of the body.

A jejunal tube (J-tube) is a synthetic entryway through the abdominal wall into the jejunum. It serves as a feeding or drug delivery aperture and may be permanent or temporary. Thus, option D is correct.

The patient is ultimately the rate-limiting element for JF. As long as the patient tolerates it, it is completely fine to try a bolus or high-rate regimen if a stable patient requests one.

Always flush the tube with lukewarm water to lower the possibility of blockages. In the case of continuous feeding, flush every 4-6 hours. When a feeding is halted, flush. J-tube does not get used; flush daily.

Therefore, many immediate-release tablets into a fine powder and dilute them before use. Crushing is not advised for extended-release (ER), sublingual, enteric-coated, or delayed-release drugs.

Answer: C. a blood clot in the coronary artery.

Explanation: The most feared outcome associated with CAD is a myocardial infarction (MI), more commonly known as a heart attack. MI is one possible form of acute coronary syndrome (ACS), the name for a rupture of coronary arteries due to plaque buildup. Specifically, MI occurs when a thrombus (blood clot) develops in a coronary artery that’s already narrowed by atherosclerosis. The complete blockage of blood flow through the coronary artery prevents the surrounding heart muscle from receiving any blood and oxygen. One proven measure to decrease the incidence of CAD and myocardial infarction is controlling cholesterol levels... PF

One common reason teens start using alcohol is peer influence and the desire to fit in and gain social approval.

One common reason teens report they start using alcohol is peer influence. Teenagers often want to fit in and be accepted by their peers, and they may perceive alcohol use as a way to gain social approval or feel more mature. They may also be influenced by media portrayals of alcohol use as glamorous or cool. Additionally, some teenagers may use alcohol as a coping mechanism to deal with stress, anxiety, or other emotional problems.

Final answer:

Teens often start using alcohol due to peer pressure, social conformity, risk-taking tendencies, and sometimes family influences. Adolescence is a critical period for identity formation, which can make teens more susceptible to experimenting with alcohol.

Explanation:

One common reason teens report they start using alcohol is peer pressure and the desire to fit in with their social group. Adolescents often face significant social pressures and may use alcohol as a means to socialize, conform, or gain acceptance among peers. This is compounded by their developmental stage, which involves seeking independence and identity formation, often leading them to experiment with behaviors like alcohol consumption despite potential risks.

Additionally, adolescents may have a natural propensity for risk-taking, which can contribute to their likelihood of trying alcohol. During teenage years, developing cognitive capabilities around evaluating risks and rewards can lead to more risk-taking behavior than seen in adults. Also, some may turn to alcohol as a coping mechanism to handle emotional ups and downs or because of family influences, such as a family history of substance abuse.

The impact of alcohol use during adolescence can be significant, leading not only to immediate consequences such as poor coordination or trouble walking but also to long-term problems like potential alcohol dependency or contributing to negative family dynamics and child abuse. Therefore, understanding these motivators for teen drinking is crucial for prevention efforts.

Frequent heartburn could be caused by overproduction of gastrin. When too much gastrin is secreted, it causes the stomach to produce too much acid; therefore, resulting in heartburn.

You get heart burns with acid reflux that’s why you should take Antacids. Antacid excess stomach acid to relieve heartburn, sour stomach, acid indigestion, and stomach upset. They can also be used to relieve the pain of stomach and duodenal ulcers.

When too much acid builds up in your stomach, it can feel upset. Alka-Seltzer is a "buffer" which keeps your stomach from being too acidic. This demonstration using bromphenol blue and vinegar, will show how Alka-Seltzer neutralizes stomach acid.

The correct answer is c. Overproduction of gastrin is the factor most directly linked to heartburn.

Heartburn is often caused by the overproduction of stomach acid, which can lead to the irritation of the esophagus. Gastrin is a hormone that stimulates the secretion of gastric acid (HCl) by the parietal cells of the stomach. Therefore, an overproduction of gastrin would lead to an increase in stomach acid, which can cause frequent heartburn.

Let's consider the options:

a. Overproduction of cholecystokinin (CCK): CCK is a hormone that, among other functions, stimulates the digestion of fat and protein. While CCK does stimulate the secretion of pancreatic enzymes and bile, it is not directly associated with the overproduction of stomach acid. Thus, it is not the primary cause of frequent heartburn.

b. Underproduction of cholecystokinin: If CCK is underproduced, this would likely result in impaired fat and protein digestion, but it would not lead to an overproduction of stomach acid. Therefore, it is not a direct cause of frequent heartburn.

c. Overproduction of gastrin: As previously mentioned, gastrin directly stimulates the production of stomach acid. An overproduction of gastrin would lead to an excess of stomach acid, which can cause frequent heartburn. This is consistent with the known physiological mechanisms.

d. Underproduction of gastrin: If gastrin is underproduced, there would be less stimulation of stomach acid production. This would not lead to frequent heartburn but rather could result in decreased digestive efficiency, particularly in the stomach phase of digestion.

The correct question is:

One cause of heartburn is overproduction of stomach acid. Frequent heartburn could be caused by which of the following?

a. Overproduction of cholecystokinin

b. Underproduction of cholecystokinin

c. Overproduction of gastrin

d. Underproduction of gastrin
