What are different types of biomolecules ?Biomolecules are the primary building blocks of our body. The primary biomolecules are Carbohydrates, Proteins, Fats, Nucleic Acids
Carbohydrates are polyhydroxy aldehydes or ketones produced by hydrolysis, collectively called as saccharides
Proteins are polymers of amino acids, can be classified as primary, secondary, tertiary and quaternary protein.
Nucleic acids are up two types namely, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
The nucleic acid involve in transfer of genetic information and proteins synthesis by processes known as translation and transcription.
The basic units of nucleic acids are composed of a nitrogenous base, pentose sugar, and phosphate.
Lipids are organic insoluble substance in water, soluble in organic solvents, are related to fatty acids, they include sterols, fat-soluble vitamins, mono-, di- or triglycerides, phospholipids, etc.

what is an enzyme that begins the digestion of proteins?
Protein digestion begins when you first start chewing. There are two enzymes in your saliva called amylase and lipase. They mostly break down carbohydrates and fats. Once a protein source reaches your stomach, hydrochloric acid and enzymes called proteases break it down into smaller chains of amino acids
How does chromosomal inheritance generate genetic variation in sexual reproduction?
Answer:
Crossing-over is the exchange of genetic material between homologous chromosomes. It results in new combinations of genes on each chromosome. When cells divide during meiosis, homologous chromosomes are randomly distributed to daughter cells, and different chromosomes segregate independently of each other.
Answer:
Independent assortment
Explanation: When cells divide during meiosis, homologous chromosomes are randomly distributed to daughter cells, and different chromosomes segregate independently of each other. This called is called independent assortment. It results in gametes that have unique combinations of chromosomes.
4. The diagram below represents a cell in water. Explain why more water is moving out of the
cell than into the cell.
Answer:
One cell has a higher concentration of solutes, and a lower concentration of water thus the water moves down the concentration gradient.
Explanation:
Water in cells readily diffuse across the selectively permeable membrane, or move via osmosis. Here, the water molecules and solutes attempt to maintain equilibrium or balance.
Thus, water moves along its concentration gradient to regions of low water concentration and high solute concentration continuously.

Meiosis is a type of cell division in germinal cells. It produces gametes that contain one complete haploid set of chromosomes. Thus, option B is correct.
What is meiosis?Meiosis is a reductional cell division that occurs in the reproductive or the germinal cells to produce the daughter cells with a haploid (n) set of the genetic material.
The chromosome gets halved and reduced by number in the meiosis I phase of the division. Here, the homologous chromosomes separate and enter daughter cells that are called the gametes.
Therefore, in meiosis, the gametes produced have half the number of chromosomes.

Which organic molecule serves as the main source of energy for cells?
A. Starch
B. Glucose
C. Proteins
Answer:
B. Glucose
Explanation:
Carbohydrates include sugars, starch, cellulose, and glycogen. Carbohydrates are the primary sources of energy for most organisms. The sugar glucose is the main source of energy for cells.
An organic molecule that serves as the main source of energy for cells is known as Glucose. Thus, the correct option for this question is B.
What is the function of glucose molecules?The function of glucose molecules is to serve as an important source of energy. This organic molecule is also known as fuel for living organisms. All those metabolic, as well as, physiologic activities are typically performed by the source of energy which is facilitated by this organic molecule specifically.
Glucose provides immediate energy to the individual in order to make themselves active and strengthen. The molecule of glucose is directly absorbed into your bloodstream and delivers energy to the cells along with the complete body. All cellular processes are performed with the help of glucose.
Therefore, glucose is a type of organic molecule that serves as the main source of energy for cells.

A bird that preys on moths is introduced to the habitat with moths and trees like the ones shown below.
Answer: c. The dark colored moths will experience disruptive selection.
Explanation:
The tree bark is light in color which means that while the light colored moths will be able to blend in, the dark colored moths will not. This will lead to the dark colored moths being hunted more by the bird leading to a sharp decrease in their numbers.
Disruptive selection occurs when an extreme trait is preferred over an intermediate one with little advantage in that environment. The dark moths will experience disruptive selection because the light moths are preferred for survival.
