The components of food known as nutrients are vital to life and health. They give us energy, the building blocks for repair and growth, and the substances needed to control chemical reactions.
Nutrients such as water, proteins, lipids (fats), carbohydrates (CHO), vitamins, and minerals. The body divides these substances into smaller components during digestion. They can now infiltrate cells and deliver energy and Disbenefits as a result. Digestion enzymes break down food as it moves from your mouth into your digestive system, transforming it into more easily absorbed nutrients. Your body wouldn't be able to do it without it.
However, the majority of chemical digestion takes place in the stomach, with some also taking place in the intestines. The stomach's hydrochloric acid does its function. The stomach's hydrochloric acid serves as a catalyst for chemical digestion. Chemical digestion is invisible at all times. We eat starches, which are chemically broken down into simple sugars.

victims of drowning who have stopped breathing are sometimes revived by a process called artificial respiration. Suggest why a biologist would object to the use of this expression. (Resuscitation is a better word to use.)
When a person experiences a drowning incident and stops breathing, immediate intervention is necessary to provide oxygen to the brain and other vital organs to prevent permanent damage or death.
Traditionally, this intervention has been called "artificial respiration" or "mouth-to-mouth resuscitation," where a person provides breaths to the victim by blowing air into their mouth to mimic the process of respiration. However, the term "artificial respiration" can be misleading because the action performed during resuscitation is not a complete replacement of the biological process of respiration as it occurs naturally in a living organism. Instead, it is an external intervention to provide oxygen to the victim until they can resume normal breathing on their own.
A more accurate and biologically precise term for this intervention is "resuscitation" or "cardiopulmonary resuscitation" (CPR). Resuscitation involves a combination of chest compressions to maintain blood circulation and rescue breaths to provide oxygen to the victim. By using the term "resuscitation," biologists and medical professionals can better convey the concept that the goal is to restore the natural processes of breathing and circulation, rather than implying the creation of an entirely "artificial" biological function.

Reading task 1 : Please read the text and answer the 12 questions that follow.
What is your hair texture? You may have wondered why your hair color is just the way it is. Genes make that happen. Living things are different because they have different characteristics. For example microbes such as bacteria, plants, to worms, fungi, algae, millions upon millions of animals. These organisms of the same species together form a population. All the genes in a population is called its gene pool. This can change over time. Generally speaking, the term evolution is “ Change over time.” When the gene pool of a population changes over time, then biological evolution has occurred. Think about a population of goldfish with that solid gold color. Supposed the color changes, then biological evolution has occurred. Biological evolution occurs by four mechanisms: migration, mutation, genetic drift, and natural selection.
A mutation is the change in DNA . Imagine some goldfish with stripes. It could just be a mutation. If the mutation is in the sperm or egg cell, it would certainly be passed on to the next generation leading to biological evolution.
Another mechanism is Migration which is movement into or out of a population. Fish gene pool can change if the population is separated over a long time. Thirdly, Genetic drift is biological evolution by chance. Think about a natural disaster that kills all but a few of the individuals of a population, the next generation would get a different gene pool from the original population just by chance.
Lastly, Natural selection is when physical characteristics that are important for reproduction and survival are passed on more frequently from parent to offspring. The conditions for natural selection is for the organisms to produce more offspring than can survive. However, organisms struggle for existence because there are limited resources limiting them from reproducing to their fullest biotic potential. So, they can not reproduce uncontrollably.

What is Mutation?Any alteration to a cell's DNA sequence. Mistakes in cell division can result in mutations, as can exposure to environmental DNA-damaging substances.
Mutations may be negative, positive, or ineffective. Mutations that take place in other types of cells are not passed on to offspring; however, if they do so in the cells that produce eggs or sperm, they may be.
Cancer and other diseases may result from specific mutations. A variation is another name for a mutation. A mutation is a change to an organism's DNA sequence.

Hydrophobic substances like salad oil are:
Answer: Molecules that are nonpolar and resist water molecules.
Explanation:
Hydrophobic substance like salad oils are the molecules that are nonpolar and resist water molecules.
Carbon and hydrogen atoms, which exchange electrons almost evenly and form nonpolar covalent bonds, make up the majority of the atoms in salad oil. Hydrophobic substances are those that lack an affinity for water while having a lot of nonpolar connections and being nonpolar ("water-fearing"). Because polar bonds cause atoms to have partial charges, substances that possess polar bonds are hydrophilic, or "loving water." For instance, the oxygen atom in a water molecule can create a hydrogen bond with a hydrogen atom that has a partial positive charge on it.

This evidence is used to suggest that life changes over time, as the genetic inheritance of each species evolves and adapts to its environment.
What is species?
A species is a group of living organisms that are able to interbreed and produce fertile offspring. All members of a species share a set of common characteristics and traits that distinguish them from other species. Species are the basic unit of biological classification and are often given a scientific name. Depending on the species, the members of a species may look similar or be quite different from each other. Species can also be distinguished from each other by their behaviour, habitat, diet, and other characteristics.

Which of the following statement is true regarding natural selection?ANatural selection may lead to evolution.BDifferences in reproduction and survival are due to variation among organisms.CThe initial population varies in many traits. Individuals have one version of some traits.DAll of the above.
Option d is Correct. Darwin introduced the concept of natural selection (survival of the fittest). This hypothesis contends that more people are created with each passing generation, and they fight for survival.
Phenotypic variation exists among individuals and the variation is heritable; those individuals with heritable traits that are better suited to the environment will survive and reproduce. Those individuals that can inherit the adaptations according to the change in the environment will survive, and the rest will die.
Differential reproduction is what is done in this situation. At the time of reproductive isolation, new species (evolution) will develop. Natural selection is demonstrated by the industrial revolution in the black peppered moth.
