When a fan is moving is convection, conduction, or raditation, and WHY?
Answer:
Moving of fan is convection.
The faster moving air from the fan displaces the warmer air that is in direct contact with our skin. This enhances the rate of convective heat transfer, which means we feel cooler.

What are biological macromolecules?Biological macromolecules are large molecules constituted of organic molecules. These are necessary for the survival of an organism. The four major classes of macromolecules in the study are Carbohydrates, Lipids, Proteins and Nucleic acids.
They are all built from carbon-based or organic molecules. These molecules form important components of a living cell and constitute most of its dry weight. These macromolecules are mostly obtained from the food we eat which is broken down into nutrients which are these organic molecules.
They are also called biomolecules. Carbohydrates are energy sources made of sugars. They are broken down into glucose which is required for cellular respiration to produce energy.
Proteins perform various functions including structural, regulatory, protective etc. Lipids are non-polar compounds that store energy for the long term in the form of fats in our bodies. Nucleic acids are hereditary biomolecules that pass on traits from one generation to another.
Therefore, the correct options are A, B, E and F.

Both complex carbohydrates and lipids can provide energy to your body as they are broker
down. However, only carbohydrates are broken down into which of the following subunits?
A sugars
B amino acids
C nucleotides
D fats
Answer:
A
Explanation:
Carbohydrates give the body energy to go about your day’s mental and physical tasks. Digesting or metabolizing carbohydrates breaks foods down into sugars, which are also called saccharides. These molecules begin digesting in the mouth and continue through the body to be used for anything from normal cell functioning to cell growth and repair
Both simple and complex carbohydrates break down into glucose (aka blood sugar). A simple carb is one that’s comprised of one or two sugar molecules, while a complex carb contains three or more sugar molecules.

You have been identifying the sequence of a segment of a protein. The sequence to date is: leucine-methionine-tyrosine-alanine-glutamine-lysine-glutamate. You insert arginine between the leucine and methionine. What effect would this have on the segment
Answer:
Inserting arginine places a positively charged amino acid in a portion that is non-polar, creating the possibility of a hydrogen bond in this area.
Explanation:
Inserting arginine places a positively charged amino acid in a portion that is non-polar, creating the possibility of a hydrogen bond in this area.
What are amino acids?The amino acids are the basic building blocks of the protein nutrient. They are made up of amino group (―NH2), an acidic carboxyl group (―COOH), and an organic R group.
An asymmetric center is the carbon atom that is bonded by four different molecules.Among all the amino acids, the ones that have more that one asymmetric center include the isoleucine and threonine.
Of all the types of amino acids listed above, isoleucine and threonine are the two amino acids that have more than one asymmetric center.The sequence to date is: leucine-methionine-tyrosine-alanine-glutamine-lysine-glutamate. You insert arginine between the leucine and methionine.
Therefore, Inserting arginine places a positively charged amino acid in a portion that is non-polar, creating the possibility of a hydrogen bond in this area.

~AH1807Peace!Which of the following statements about the causes of mental illness is NOT true?
O It is not caused by poverty.
O It is not the result of personal weakness or deficits in personality.
O Experiences a person has as a child play no role in causing mental disorders.
It is not the consequence of poor parenting or bad behavior.
Answer:
experiences a person has as a child play no role in causing mental disorders.
Explanation:
because one person have to act as his/her age level.
The statement that is NOT true experiences a person has as a child play no role in causing mental disorders, the correct option is (c).
Childhood experiences can significantly influence mental health outcomes. Adverse experiences like abuse, neglect, trauma, or dysfunctional family environments can have long-lasting effects on an individual's psychological well-being. Research shows that these negative experiences can increase the risk of developing mental disorders later in life, such as anxiety, depression, and post-traumatic stress disorder.
Early intervention and support are crucial in addressing the impact of childhood experiences on mental health. Understanding and addressing these underlying factors can help individuals cope with their conditions and work towards recovery. Recognizing the role of childhood experiences in mental illness highlights the importance of a holistic approach to mental health care, emphasizing prevention and early intervention, the correct option is (c).

Which two elements in the list would bond together based on their ionic charges?
A. calcium and potassium
B. potassium and neon
C. potassium and iodine
D. calcium and neon
Answer:
It's C. Potassium and iodine
The two elements in the list that would bond together on their ionic charges is potassium and iodine. The correct option is C.
What is ionic bond?Ionic bond, also known as electrovalent bond, is a type of linkage formed in a chemical substance by the electrostatic attraction of ions with opposite charges.
When the valence (topmost layer) electrons of one atom are indefinitely transmitted to another, a bond is formed.
The complete transmission of valence electron(s) among both atoms is referred to as ionic bonding.
It is a chemical bond that produces two opposing ions. The metal loses electrons in ionic bonds to become a positively charged cation, meanwhile the nonmetal chooses to accept those electrons to become a negatively charged anion.
Ionic bonds are formed by potassium iodide (KI). Iodine and potassium have very divergent electronegativities.
Since ionic bonds form between atoms with a large difference in electronegativity, the two atoms would form an ionic bond.
Thus, the correct option is C.

Describe the effect of increased carbon dioxide concentration on blood pH
Answer:
As it combines with water, it forms carbonic acid, making the blood acidic. So CO2 in the bloodstream lowers the blood pH. When CO2 levels become excessive, a condition known as acidosis occurs. This is defined as the pH of the blood becoming less than 7.35
The increase in the carbon dioxide concentration on blood pH leads to the condition known as Acidosis.
What is the normal blood pH?The level of normal blood pH in humans significantly ranges from 7.35 to 7.45 on a pH scale. It is considered neutral but experimentally it is slightly basic in nature.
As the concentration of carbon dioxide in the blood increases, the carbon dioxide in the presence of water forms carbonic acid which lowers the blood pH from 7.35.
This reduction in blood pH is known as acidosis. This is caused by the overproduction of acid within the body due to excessive concentration of carbon dioxide in the blood's pH. Acidosis leads to feeling fatigued, lethargic, muscle aches, etc.
Therefore, the concentration of carbon dioxide on blood pH negatively harms the health of an individual.

RNA, ATP, ADP, OR DNA?
The energy needed for chemical reactions in the body is provided by the breakdown or hydrolysis of ATP.
What is ATP?Adenosine triphosphate (ATP) is a higher energy molecule that is used to carry out cellular functions by breaking down their phosphate bonds.
ATP is produced in the body by means of a process known as cellular respiration and serves to carry out different metabolic functions (e.g., growth, reproduction, etc).
The hydrolysis of high-energy phosphate bonds present in the ATP molecule is required to perform many different physiological processes in multicellular organisms.
