- Explain how the acids listed below are alike and different.
amino acid fatty acid folic acid

Answers

Answer:Amino acid is considered as organic compounds that comprise amine and carboxyl functional groups, with a side chain precise to each amino acid. While fatty acid is made up of of a hydrocarbon chain and a terminal carboxyl group that ensues as ester of fats and oils. Then folic acid also known as vitamin B9, is used as a nutritional supplement and invigorated foods. It benefits the body to produce and preserve cells.

Explanation:

Amino acids are chemical molecules that contain amine and carboxyl functional groups, as well as a side chain unique to each amino acid. While fatty acid is made up of a hydrocarbon chain with a terminal carboxyl group that results in fats and oils becoming esterified. Folic acid, often known as vitamin B9, is then utilized as a dietary supplement and to energize foods. It is advantageous to the body to make and keep cells.

Amino acid, fatty acid, and folic acid are all different types of organic acids that have some similarities and differences.

Amino acids are organic compounds made up of amino group and a carboxyl group. They are used to build proteins and also act as signaling molecules. Fatty acids, on the other hand, are long chains of hydrocarbons with a carboxyl group at one end.

They are a vital component of cell membranes and also act as an energy source. Folic acid is a type of B vitamin that helps the body to produce and maintain new cells. It also plays a role in DNA synthesis and repair. It is commonly found in leafy green vegetables and citrus fruits.

Now, let's compare the three acids:

Similarities: 1. All three are organic acids.

2. All three have a carboxyl group.

Differences: 1. Amino acids are the building blocks of proteins, whereas fatty acids and folic acid are not.

2. Fatty acids are mainly used as an energy source, whereas amino acids and folic acid are not.

3. Folic acid is a B vitamin, whereas amino acids and fatty acids are not vitamins.

Hence, amino acid, fatty acid, and folic acid are different types of organic acids with some similarities and differences.

You are alone and have identified an adult who is not responsive. You have

O
A. Try to find a pulse.
O
B. Begin chest compressions.
O
C. Begin rescue breaths.
O
D. Go get help.
SUBMIT

Answers

B should be the answer

In CPR (Cardiopulmonary Resuscitation), after calling 911, the next step would be to begin chest compressions. So the correct answer is B. Begin chest compressions.

Chest compressions are a critical component of CPR, especially when dealing with a person who is unresponsive and not breathing. By performing chest compressions, you can help circulate blood and oxygen throughout the body, which is crucial in maintaining vital organ function during an emergency situation.

Rescue breaths are also important in CPR, but in some modern CPR guidelines (like hands-only CPR), chest compressions alone may be recommended for untrained individuals or when providing assistance over the phone until professional help arrives. However, if you are trained in CPR and comfortable providing rescue breaths, you may incorporate them along with chest compressions as needed.

When scientists analyzed drilling samples from the Glomar Challenger study, which discovery did they make about rocks in relation to a mid-ocean ridge?

Answers

Scientists made the discovery that the rocks found near a mid-ocean ridge are young and have not been subjected to the same level of heat and pressure as the rocks found farther away from the ridge.

What was the Glomar Challenger study?

The Glomar Challenger study was a scientific ocean drilling project that took place between 1968 and 1983. It was the first large-scale international ocean drilling program and was funded by the United States National Science Foundation. The study was named after the research vessel that was used for the drilling, the Glomar Challenger.

The main goal of the Glomar Challenger study was to understand the geology of the ocean floor and how it has evolved over time. To do this, scientists used the Glomar Challenger to drill deep into the ocean floor and collect samples of rock and sediment. These samples were then analyzed in the laboratory to study the composition, age, and other characteristics of the rocks and sediments.

The Glomar Challenger study made many important scientific discoveries, including the existence of hydrothermal vents on the ocean floor and the process of sea-floor spreading, which is the process by which new crust is formed at the mid-ocean ridge. The study also helped to establish the field of marine geology and provided a wealth of data that continues to be used by scientists today.

How much water does a person need daily?

Answers

About 15.5 cups (3.7 liters) of fluids for men
About 11.5 cups (2.7 liters) of fluids a day for women. These recommendations cover fluids from water, other beverages and food. About 20 percent of daily fluid intake usually comes from food and the rest from drinks.

An adult should consume 3.7 liters (125 ounces) for males and 2.7 liters (91 ounces) for females of total water each day as per IOM recommendations, but this amount may increase depending on factors such as body weight, physical activity, and climate. The human body is mostly water, highlighting its importance for bodily functions. Daily usage of water in a typical U.S. household includes a plethora of activities leading to about 100 gallons of water used.

The amount of water an individual needs daily can vary based on several factors, including their size, gender, activity level, and the climate they live in. A balance between water intake and loss is crucial to maintain hydration. On average, adults should consume 3.7 liters for males and 2.7 liters for females of total water from all foods and liquids, according to the Institute of Medicine (IOM) recommendations. This equates to about 125 ounces or approximately 13 cups for men, and 91 ounces or about 9 cups for women. The human body is composed of up to 60% water, and water is essential for all living cells and functions.

For physical activity and environmental factors, fluid intake can range from half an ounce to 1 ounce per pound of body weight. For a 150-pound individual, that would mean a range of 75-150 ounces of water per day. While a person only requires about 1 gallon to survive, typical daily usage in a U.S. household is around 100 gallons, considering all activities that involve water, such as cooking and hygiene.
