More individuals with beneficial mutations will survive than those without it, and it will lead to an increase in the expression of those certain traits throughout the population through increases and decreases of specific traits.

Any modification to a species' structure or behavior that makes it more suited to surviving and procreating in its environment is referred to as an adaptation. Random mutations can cause the expression of particular features to become more prominent. Natural selection will result in an increase in the expression of specific features throughout the population since more people with advantageous mutations will survive than those without them.

Physical characteristics of an organism, such as the bill on a bird or the fur on a bear, are examples of structural adaptations. Behavioral adjustments make up the rest. Organisms use behavioral adaptations to help them survive. Bird migration and calls are two examples of behavioral adaptations.

Once pyruvate is produced in glycolysis, cell has two choices, without oxygen, option that it does not have: A.) Oxidative phosphorylation. It is the final stage of aerobic cellular respiration.

When oxygen is not present, pyruvate undergoes a process called fermentation. In the process of fermentation, NADH + H+ from glycolysis will be recycled back to NAD+ so that glycolysis can continue. In the glycolysis, NAD+ is reduced to form NADH + H+.

If insufficient oxygen is available, acid is broken down anaerobically, producing lactate in animals and ethanol in plants and microorganisms.

In 1953, James Watson and Francis Crick proposed the double helix model of DNA, which revolutionized the field of genetics. The discovery of the structure of DNA was a monumental achievement, it  was important breakthrough in establishing DNA as the molecule of heredity.

In 1935, American microbiologist Wendell Stanley demonstrated that a virus is composed of proteins and nucleic acids, proving that viruses are complex, living organisms. Stanley also identified and labeled the proteins and nucleic acids of the virus he was studying, which allowed him to conclude that the nucleus of this virus was composed of DNA. This was the first time that a scientist had identified and labeled the DNA and proteins of a virus, and it demonstrated that DNA is the molecule of heredity.

In the 1940s, American virologist Alfred Hershey and Canadian biologist Martha Chase conducted a series of experiments to study the composition of viruses. They used a radioactive isotope of phosphorus to label the proteins of a virus, and a radioactive isotope of sulfur to label the DNA. By doing this, they were able to prove that the DNA of the virus was the molecule responsible for heredity. This was the first time that scientists had labeled the DNA and proteins of a virus to demonstrate that DNA is the molecule of heredity.

Decade is closely aligned with the 2030 Agenda for Sustainable Development which outlines 17 Sustainable Development Goals that aim to achieve a more sustainable and equitable world for all.

The Decade focuses on the restoration of degraded ecosystems, which is essential for the achievement of the Sustainable Development Goals. Ecosystems are essential for the health and vitality of the planet and its inhabitants. They provide a variety of resources such as food, water, and medicine, and they regulate the climate and provide habitat for many species of plants and animals. When these ecosystems are degraded, they can no longer provide these essential resources and services.

The Decade on Ecosystem Restoration seeks to address this problem by focusing on the restoration of these ecosystems. This includes activities such as reforestation, restoring wetlands, and rehabilitating degraded land. These activities not only help restore ecosystems, but they also help reduce poverty and improve the livelihoods of people living in these areas. For example, restoring wetlands can help provide water for irrigation, while rehabilitating degraded land can help improve crop yields and provide more income for local communities.

A kelp forest can be safeguarded by the presence of sea otters. They consume a lot of sea urchins, which controls their population and keeps the kelp forest from being destroyed. One of the foundational species of the coastal ecology is the sea otter.

Marine animals known as sea otters (Enhydra lutris) live along the coasts of the Aleutian Islands and North America's mainland up to Mexico.. Fish, sea urchins, mollusks, and crustaceans make up the majority of sea otters' diets.  Sea otters are keystone species is one that has a significant, calming effect on the entire ecological community.

A versatile sea vegetable, kelp can be eaten raw, cooked, or as a component of several supplements. Sushi, salads, sauces, and other dishes must all have kelp. Particularly sea otters are essential to the health of kelp forests, which are essential to the health of the bay. Sea urchins, which may completely devastate kelp beds without them, instead eat the stripes of huge kelp plants, which are not consumed by sea otters.

Sea otters play a key part in the kelp forests around the coast of Alaska. More than 20 distinct species of fish live in kelp forests, which also serve as spawning and breeding grounds for herring, atka mackerel, and salmon fry nurseries. Sea otters contribute to the energy flow between the ocean and kelp forest. Sea otters feed on kelp forests because they are dense, which opens up the canopy to let sunlight reach the floor and feed herbivores. Because sea otters graze on urchins, a primary pest in kelp forests, the urchin population is impacted, which harms the canopy of kelp forests.

The first factor is temperature; normally, a reaction is sped up or slowed down depending on the temperature. The second factor is pH; each enzyme has a preferred pH range. these two factors affect the active site and enzyme function.

The average kinetic energy of a system is measured by its temperature. The kinetic energy of a system starts to rise as the particle's velocity increases, which raises the system's temperature. The energy that is transferred when two bodies with different surface temperatures come in touch is referred to as heat.

Proteins called enzymes serve as biological catalysts by quickening chemical reactions. Substrates are the molecules that enzymes can interact with, and the enzyme changes the substrates into other molecules known as products.

The area of an enzyme where substrate molecules bind and undergo a chemical reaction is known as the active site. The amino acid residues that make up the active site are those that catalyze the reaction of the substrate and those that temporarily binds with the substrate.

With the help of photosynthesis, the pea plants can take in carbon from the air. The carbon is used to make energy storage molecules.

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.

The energy from light causes a chemical reaction that breaks down the molecules of carbon dioxide and water and reorganizes them to make the sugar (glucose) and oxygen gas.

The main purpose of photosynthesis is to convert radiant energy from the sun into chemical energy that can be used for food. Cellular respiration is the process that occurs in the mitochondria of organisms (animals and plants) to break down sugar.
