Notes

Watch the video clip and answer the following guided question.

1.Why the different Biological Molecule is important?
Six elements account for the majority of living things (Carbon, oxygen, Nitrogen, Sulphur, Phosphorous and Hydrogen). They make up around 90% of the dry weight of humans. Biomolecules are those that are created by living things and are crucial for their daily operations. They are dependent on the structure and lose their functionality when it is disrupted. They typically consist of small building blocks called monomers, which chemically combine to create big, complicated polymers. All biomolecules are composed of three basic elements: carbon, hydrogen, and oxygen. For the purposes of biology homework help, biomolecules may be generically divided into four categories: carbohydrates, proteins, lipids, and nucleic acids.
2.What is the benefit of Carbohydrate?
Carbohydrates are organic compound that contains various types of sugar units. Carbohydrate is widely known as the main source of the energy in your daily life. But, since many people have some problems with carbohydrate, especially associated with their weight gain, other people become a little bit dubious when they’re consuming carbohydrates, while the amount of people who choose to avoid carbohydrates at all costs is also huge. Carbohydrate is very fundamental in your daily life. The following statements will show you how important carbohydrate is for your life.
3.What is the benefit of Protein?
Protein is the one item I always advise to my clients. Everyone benefits from protein, whether they are serious athletes or just occasional gym visitors. Protein plays so many vital functions in your body, notably for the development of muscles. Protein provides advantages for everybody from bodybuilders to runners to yoga practitioners. I rigorously concentrate on dietary protein and supplement with protein powder. My personal fitness routine and that of my clients have never failed to produce positive outcomes for me!
4.What is the benefit of Lipids?
Lipids are molecules that are not water-soluble. Lipids in the body include hormones, fats, oils, and waxes. They are essential to your health, as they are involved in a range of functions from cell signaling to fueling the body with energy. However, they can also contribute to disease. Lipids that commonly cause issues are cholesterol and triglycerides. Found in the foods you eat, too much cholesterol can harm your heart. High levels of these lipids are also linked to an increased risk of stroke, diabetes, and high blood pressure. This article discusses the different types of lipids in the body and what they do. It also explains how lipids are measured, the risks of having high lipid levels, and how to prevent lipid-related health problems.
5.What is the benefit of Nucleic Acid?
Despite a paucity of evidence, proponents assert that nucleic acid-rich diets can provide a number of advantages, including a stronger immune system, easier digestion, and speedier muscle recovery (2). Your body can produce nucleic acids from scratch in addition to getting them from food. In actuality, your body usually creates enough nucleic acids to meet all of your requirements. More nucleic acids may be required than your body can make, particularly during times of illness, injury, or development. Nucleic acid-rich meals can help make up the difference in these situations (2). Most foods were once live organisms before they were put on your plate. Thus, at least some nucleic acids are present in these meals. It's crucial to think about

Guided question. Discussion wil be on next synchronous meeting.

1. What are the types of IMFA?
The three major types of intermolecular interactions are dipole–dipole interactions, London dispersion forces (these two are often referred to collectively as van der Waals forces), and hydrogen bonds.
2.What is Dipole-Dipole forces of attraction?
Dipole-dipole forces, also known as dipole-dipole interactions, are the electrostatic forces between two permanent polar molecules. Generally, the positive end of one molecule is attracted to the negative end of another molecule. As a result, the two molecules come closer, adding to the stability of the substance. This interaction is different from a regular ionic or covalent bond since there is no transfer or sharing of electrons.
3. What are Hydrogen Bonds?
A hydrogen bond is a type of attractive (dipole-dipole) interaction between an electronegative atom and a hydrogen atom bonded to another electronegative atom. This bond always involves a hydrogen atom. Hydrogen bonds can occur between molecules or within parts of a single molecule. A hydrogen bond tends to be stronger than van der Waals forces, but weaker than covalent bonds or ionic bonds. It is about 1/20th (5%) the strength of the covalent bond formed between O-H. However, even this weak bond is strong enough to withstand slight temperature fluctuation.
4. What are London Dispersion Forces of attraction?
So, we may say that the intra-molecular forces of attraction that develop within a molecule are the covalent bond, ionic bond, and coordination bond. The intermolecular force of attraction refers to the forces of attraction that hold molecules together. These forces are less powerful than those between molecules. Any compound's liquid, solid, and solution states are caused by these forces. London dispersion, dipole-dipole, hydrogen bonding, and ion-ion force are a few examples of common intermolecular interactions.

For your asynchronous later. Watch the video clip about the octet rule and answer the following guiding question. The discussion will be on next synchronous meeting.

1. What is octet rule?
The octet rule dictates that atoms are most stable when their valence shells are filled with eight electrons. It is based on the observation that the atoms of the main group elements have a tendency to participate in chemical bonding in such a way that each atom of the resulting molecule has eight electrons in the valence shell. The octet rule is only applicable to the main group elements. The molecules of the halogens, oxygen, nitrogen, and carbon are known to obey the octet rule. In general, the elements that obey this rule include the s-block elements and the p-block elements (except hydrogen, helium, and lithium). The octet rule can be observed in the bonding between the carbon and oxygen atoms in a carbon dioxide molecule, as illustrated via a Lewis dot structure below.
2. What is lewis dot structure?
Lewis structure is basically a graphic representation of the electron distribution around an atom. The major reason why learning Lewis dot structure is important is that it helps in predicting the number and type of bonds which can be formed around an atom. It also helps in predicting the geometry of the molecule. Learning to make proper Lewis dot structures can help in solving the problem that most of the students have.
3. What are the types of chemical bonding?
Various states, such as plasma, Bose-Einstein condensates, fermionic condensates, and quark-gluon plasma, are possible regardless of the common times of solid, liquid, and gas – for example, water exists as ice, liquid water, and vaporous steam – but various states, such as plasma, Bose-Einstein condensates, fermionic condensates, and quark-gluon plasma, are also possible. Apart from that, it is divided into pure substances and mixtures.

For your asynchronous. Watch the video clip on the formation of light elements. Answer the following guide question on your notebook or any piece of paper.

1. What is an isotope?
Isotopes can be defined as the variants of chemical elements that possess the same number of protons and electrons, but a different number of neutrons. In other words, isotopes are variants of elements that differ in their nucleon ( The total number of protons and neutrons) numbers due to a difference in the total number of neutrons in their respective nuclei.
2. What are the 2 light elements formed?
That's a lot to cover; what exactly do you mean by "light" elements? Actually, immediately after the Big Bang, as the infant cosmos cooled sufficiently for matter to form, hydrogen and helium were formed. Beyond that, the creation of elements was left to the early stars. A number of other elements, including helium, are being created by our sun.
3. What are the 4 concept takes place during the bigbang?
In 1927, Roman Catholic priest and physicist Georges Lemaitre independently calculated the Friedman solution and again suggested that the universe must be expanding. This theory was supported by Hubble when, in 1929, he found that there was a correlation between the distance of the galaxies and the amount of redshift in that galaxy's light. The distant galaxies were moving away faster, which was exactly what was predicted by Lemaitre's solutions. In 1931, Lemaitre went further with his predictions, extrapolating backward in time find that the matter of the universe would reach an infinite density and temperature at a finite time in the past. This meant the universe must have begun in an incredibly small, dense point of matter, called a "primeval atom." The fact that Lemaitre was a Roman Catholic priest concerned some, as he was putting forth a theory that presented a definite moment of "creation" to the universe. In the 1920s and 1930s, most physicists—like Einstein—were inclined to believe that the universe had always existed. In essence, the big-bang theory was seen as too religious by many people.
