The three important parts that can be found in the structure of an atom are protons, neutrons, and electrons. Protons are positively charged particles located in the nucleus of an atom.

They have a mass of 1.6726 x 10-27 kg, which is approximately 1800 times the mass of an electron. In an atom, the number of protons equals the number of electrons, and the number of protons determines the element. For example, hydrogen has one proton, helium has two protons, and so on.

Neutrons are neutral particles located in the nucleus of an atom. They have a mass of 1.6749 x 10-27 kg, which is approximately the same as the mass of a proton. Neutrons can help to stabilize the nucleus of an atom by increasing its mass and preventing it from decaying. The number of neutrons in an atom varies, and can be different from the number of protons. This can lead to different isotopes of the same element.

Electrons are negatively charged particles located in the electron cloud, which is the region of space surrounding the nucleus of an atom. They have a mass of 9.109 x 10-31 kg, which is approximately 1/1800th.

In the night time, the pH of the water became acidic because of the reverse reaction of photosynthesis in which Hydrogen ions were produced as result.

In the dark condition or night when sufficient amount of sunlight is not present, plants do no undergo photosynthesis. This is because in absence of light, plants are unable to use carbon dioxide and water to produce glucose and O2 as sunlight acts as a catalyst to begin the reaction. During day, underwater photosynthesis rate exceeds respiration in plants. In dark, the plants respire like normal animals wherein they release carbon dioxide and water vapors are produced. These water vapors are in the form of hydrogen ions which makes the pH acidic. Carbon dioxide in itself is not acidic as such.

Heredity, also known as inheritance or biological inheritance, is the transmission of qualities from parents to their children; offspring cells or organisms receive genetic information from their parents through asexual or sexual reproduction.

In humans, eye colour is an example of an inherited trait: a person may receive the "brown-eye trait" from one of their parents. Genes influence inherited characteristics, and the total collection of genes within an organism's genome is referred to as its genotype. Heredity in biology refers to the transmission of genetic elements from parents to children or from one generation to the next.

a cell typically spends 95 percent of the time required to complete a full cell cycle in interphase.

cell cycle can be broadly divided into 2 phases:

interphaseM phase

Interphase is the time when the cell prepares for division by going through both cell growth and DNA replication. It is often referred to as the resting phase of the cell cycle. It is further divided into:

The G1 phase: (also known as the "Gap 1") is the time period a cell goes through between the completion of mitosis and the start of genetic material replication. The cell is metabolically active and continues to expand throughout this stage without repeating its DNA.

S phase: DNA replication occurs in the S phase (Synthesis), which is the next phase. If the cell's starting DNA content is represented as 2N, replication results in 4N. However, the number of chromosomes does not change; for example, if 2n chromosomes were present during the G1 phase, they would still be present by the conclusion of the S phase. In cells that contain centrioles, the centriole also splits into two centriole pairs.

G2 phase: As the cell gets ready to enter the mitotic phase, the G2 phase (also known as the "Gap 2") is where the RNA, proteins, and other macromolecules needed for the expansion of cell organelles, spindle formation, and cell development are created.

Adaptation: Any inherited trait that enhances an organism's capacity for survival and reproduction.

Natural selection is one way evolution occurs. It is more likely for organisms that have adapted to their environment to survive and pass on the genes that made them successful. This process causes species to evolve and diverge over time.

According to Charles Darwin's theory of evolution by natural selection, organisms that have heritable traits that make them more adept at adjusting to their environment than other members of their species will have a higher chance of surviving, procreating, and transferring more of their genetic material to the following generation.

The varying morphology of red blood cells due to pitting, culling, filtering, and persistence of abnormal red blood cells in the peripheral blood is most likely caused by splenectomy

Red blood cells or erythrocytes are the most numerous blood cells in the body and are produced in the spinal cord. Inside the red blood cells, hemoglobin is stored, which is a respiratory pigment that binds oxygen or carbon dioxide molecules. Oxygen will be transported to various tissues and organs of the human body. The characteristics of red blood cells are red, flat in shape, and do not have a cell nucleus.

Splenectomy is a procedure performed by surgeons to remove the spleen and treat blood diseases such as hemolytic anemia. In hemolytic anemia, the red blood cells are abnormal so that antibodies attack the red blood cells and are destroyed by the spleen. Then splenectomy is needed to prevent blood transfusions.

If the resistant individuals continue to survive and prosper, new resistant populations might emerge. this would be an example of natural selection

Natural selection is where specific qualities or features, depending on their propensity to aid individuals in surviving and procreating, gradually become more or less prevalent in a population over time. Chytridiomycosis-resistant people who endured and thrived despite the illness have an attribute that has made it possible for them to do so. This characteristic may be inherited genetically from one parent to the next or it may be acquired by process, like building up immunity through exposure to the disease.

New resistant populations will form as long as these resilient people persist and procreate, passing on their resilient traits to their progeny. If the disease's selective pressure persists, the proportion of resistant people in the population is likely to rise over time while the proportion of non-resistant people falls.

Many other coarse-grained models have been put forth.
