Explain molecules
Answer:
Molecules are parts of stuff all over in the air
Explanation:
____are compounds that produce H+ ions in solution.
Answer:
An acid is a substance or compound that releases hydrogen ions (H+) when in solution. In a strong acid, such as hydrochloric acid (HCl), all hydrogen ions (H+), and chloride ions (Cl-) dissociate (separate) when placed in water and these ions are no longer held together by ionic bonding.

Answer:
1. Glucose itself is a monomer of both sugar and starch. A monomer is a component of a polymer; in other words, many monomers come together to form a polymer.
2. Proteins
3. Nucleic acids
4. It is made of monomers called of Fatty Acids and Glycerol which are made mostly of Carbon, Oxygen, and Hydrogen atoms with mostly C and H, and a few O atoms.
5. What three elements do all bio molecules have in common? Carbon, hydrogen, and oxygen.
6. Glucose has the chemical formula`C_6H_12O_6` and is a 6-carbon sugar. Each of these carbon atomsare connected to an oxygen atom and a hydrogen atom. However, 5 of these carbon atoms are connected to hydroxyl group or OH-.
7. Each molecule contains a central carbon (C) atom, called the α-carbon, to which both an amino and a carboxyl group are attached. The remaining two bonds of the α-carbon atom are generally satisfied by a hydrogen (H) atom and the R group.
8. To form a nucleotide, a base connects to the first or primary carbon of ribose or deoxyribose.
9. 2:1
10. Nitrogens and sometimes sulfur.
11. Phosphorous
12. Cellulose, in contrast, is linear, consisting of a long chain of glucose monomers with hydrogen bonds interspersed between carbon atoms at regular intervals.
13. The first picture going from left to right is nucleic acid, the second one is lipid, the third one is carbohydrate, and the last one is protein.
Explanation:
How are amino side chains usually classified? a. Small, Medium, or Large b. Straight, branches, or ringed c. Charged, polar, or non-polar d. Reactive or non-reactive
Answer:
C. Charged, polar, or non-polar
Explanation:
Amino side chains, also called R groups, are classified into the categories of charged, polar, and non polar.
These classifications can be determined by the structure and elements within the R group/functional group.
Glucose is a building block of carbohydrates. Which of these best describes glucose?
A. nucleotide
B. protein
C. monosaccharide
D. lipid
Answer:
monosaccharide
Explanation:
Glucose is called a simple sugar or a monosaccharide because it is one of the smallest units which has the characteristics of this class of carbohydrates.
Glucose is the simplest monosaccharide which cannot be broken down further. Thus, option C is correct.
What is Glucose?Glucose is the primary component of carbohydrates. Glucose is a monomer made up of carbon, hydrogen and oxygen. Molecular formula of glucose is C6H12O6.
The functional group in glucose is an aldehyde present at the first carbon atom.
Glucose is called monosaccharides because it cannot be hydrolysed further. It is the simplest carbohydrate also referred as simple sugars.
Glucose molecules are chiefly linked together forming a glycosidic bond by removal of water molecule and form a disaccharide.
Glucose is chiefly produced by plants during the process called photosynthesis.
Glucose is the key component in metabolism. It provides energy to the body cells to carry out physiological activities. Glucose is found in blood.
Excess of glucose in the blood results in a medical condition called diabetes. It can be life threatening if not managed on time.

The secondary structure of a polypeptide is produced by bonds between amino
acids.
Describe how.
The order in which the amino-acids are placed within the polypeptide determines the tertiary structure and therefore the function of the given protein. Amino acids have different functional groups like methyl(CH3), phenyl(C6H5). Those functional groups can interact with molecules like glucose determining reactions, the proteins that catalyze reactions are called enzymes. Other functional groups of amino acids can be the sulfate groups. For example, insulin has 2 polypeptide chains(Chain A has 21 amino acids, and chain B, 30). Between the two polypeptide chains, 2 disulfide bonds form altering its shape.
The secondary structure of a protein is generated by hydrogen bonds between atoms of the polypeptide backbone.
A hydrogen bond is an intramolecular attraction between a hydrogen atom in one molecule and an electronegative atom (e.g., oxygen) of another molecule.The most common types of secondary structures in proteins are alpha helices and beta sheets.In alpha helices, the carbonyl group of one amino acid is bonded to the amino group of another amino acid spaced four residues apart in the polypeptide chain.In beta-sheets, different regions of the polypeptide line up next to each other, thereby these protein regions interact by hydrogen bonds.In conclusion, the secondary structure of a protein is generated by hydrogen bonds between atoms of the polypeptide backbone.

How do animals obtain usable nitrogen? Why is it important?
Nitrogen in Plants
Nitrogen in PlantsNitrogen is so vital because it is a major component of chlorophyll, the compound by which plants use sunlight energy to produce sugars from water and carbon dioxide (i.e., photosynthesis). It is also a major component of amino acids, the building blocks of proteins
Answer:
Through eating plants and animals.
Explanation:
Usable nitrogen is not achievable simply. It can also not be obtained directly. Animals must receive nitrogen from consuming plant-based foods (plants) or other animals.
Nitrogen is significantly relevant/important to animals and plants since nitrogen produces proteins to these animals and chlorophyll to the plants. Nitrogen also helps with the growth and creation of DNA towards animals and plants.
Explain how critical thinking helps scientists analyze information for accuracy and bias.

Which of the following is the most likely outcome of Leigh syndrome on affected mitochondria?
Answer:
The loss of this protein reduces the formation of normal COX complexes, which impairs mitochondrial energy production. The most common mtDNA mutation in Leigh syndrome affects the MT-ATP6 gene, which provides instructions for making a piece of complex V, also known as the ATP synthase protein complex.

You are conducting a photosynthesis experiment to determine how much oxygen is produced over a 24-hour period of time. You are measuring the oxygen production every hour for 24 hours.
Answer:
Measure only daytime.
Explanation:
It is useless to measure the oxygen production every hour for 24 hours because oxygen is produced during day time due to the presence of photosynthesis process. Oxygen is produced in large amount during photosynthesis, some oxygen is used in respiration while the remaining diffuse out from plant body through stomata. After vanishing sunlight, the photosynthesis process stop and no production of oxygen occur. So only measure oxygen production at daytime as compared to every hour for 24 hours.

what do you observe at low temperature medium temperature and high temperature
The temperature of a body can be related to the energy transferred between the particles of the body. Hence, temperature is directly proportional to the energy of the particles in the sample.
The kinetic energy possessed by the particles in a sample is highest at the highest temperature attained by the body. The kinetic energy drops as the temperature drop s from high to medium to low temperature. Hence, the low temperature samples have very low kinetic energy.Therefore, the energy possessed by the particles of a sample is directly proportional to the temperature of the sample.
