Answer:

The body has levels of organization that build on each other. Cells make up tissues, tissues make up organs, and organs make up organ systems. The function of an organ system depends on the integrated activity of its organs. The survival of the organism depends on the integrated activity of all the organ systems, often coordinated by the endocrine and nervous systems.

Explanation:

In the human body, cells are the basic units of life. Groups of cells working together for a specific function form tissues. Organs are two or more tissues operating together. Even separate organs work together, forming body systems.

Hope this helps :) !!!

Cells form tissues, tissues combine to form organs, and organs work together to create organ systems, collectively maintaining the overall functioning of the human body.

Inside the human body, cells are the fundamental building blocks of life. They're arranged to form tissues. Organs are structures composed of different types of tissue, which perform certain functions. These organs are formed by the combination of tissues.

Organs, in turn, work together to create organ systems. Organ systems are groups of organs that work together in order to perform more extensive functions that allow a body to survive and function properly. Each organ system plays an important role in maintaining homeostasis and interacts with other systems.

Explanation:

It is easier than solving solving matrices problems.

Energy requiring metabolic pathways that yield complex molecules from simpler precursors are: anabolic. The correct option is (B).

Anabolic pathways are those metabolic pathways in which simple molecules are combined to form more complex molecules. These pathways require energy, usually in the form of ATP, to drive the chemical reactions that synthesize complex molecules from simpler precursors.

Anabolic pathways play an important role in building the macromolecules needed for cellular structures and functions, such as proteins, nucleic acids, and complex carbohydrates. These pathways are also involved in the storage of energy in the form of glycogen, lipids, and other complex molecules.

Examples of anabolic pathways include protein synthesis, DNA replication, and glycogen synthesis. These pathways are often linked to catabolic pathways, which break down complex molecules into simpler ones and release energy.

Together, anabolic and catabolic pathways maintain the balance of chemical reactions in the cell, allowing it to grow, divide, and carry out its functions.

C. A single copy of the mutation in a diploid organism that creates a gene product with enhanced or new functions.

Dominant gain-of-function mutations are mutations that result in a gene product with enhanced or new functions. These mutations only require one copy in a diploid organism to produce the phenotype. They are dominant because the mutated gene product can override the function of the normal gene product produced by the other allele. This results in an altered phenotype that is different from the wild type.

Dominant gain-of-function mutations can have significant effects on an organism's fitness and can lead to disease in humans. Examples of dominant gain-of-function mutations include the Huntington's disease gene, which produces a protein that is toxic to neurons, and the oncogene Ras, which is involved in the development of cancer.

The first step in the replication of DNA is catalyzed by the enzyme DNA helicase.

DNA replication, as used in molecular biology, is the process by which one DNA molecule is biologically converted into two identical copies of DNA. The most crucial component of biological inheritance is DNA replication, which happens in all living things. In addition to ensuring that each of the new cells receives a copy of the DNA, this is crucial for cell division during tissue growth and repair. Replication of DNA is crucial because the cell's unique ability to divide makes it.

Enzymes called helicases can modify or bind to complexes of nucleic acids or proteins that include nucleic acids. Helicases are present in both DNA and RNA. DNA helicases are necessary for DNA replication because they divide double-stranded DNA into single strands, allowing each strand to be replicated separately. At locations known as origins, where synthesis will begin, DNA helicases unwind DNA during DNA replication. The replication fork, so named because the two strands of DNA seem forked as they are unzipped apart, is a structure that is formed as the DNA is further unwound by the DNA helicase. In double-stranded DNA, energy is required to dissociate the hydrogen bonds that bind the base pairs together.

Answer:

Plastic is a physical contaminant

Explanation:

Answer:

Increases.

Explanation:

The pH of the intermembrane space increases as the poisoning of cyanide occurs. After cyanide poisoning, the electron transport chain can stop pumping of electrons into the intermembrane space. The pH of the intermembrane space would increase, the pH gradient would also decreases, and ATP synthesis would stop to occur. The pH of the intermembrane space is neutral i.e. 7 but due to cyanide it move towards basic.

Answer:

Cyanide inhibits cytochrome c oxidase, a component of the electron transport chain. If cyanide poisoning occurs, the pH of the intermembrane space becomes more basic. The electron transport chain can no longer pump hydrogen ions into the intermembrane space and ATP synthesis stops.

Dead organisms undergo a process known as decomposition when they are broken down. Also known as rotting or decay, it occurs as a result of microorganisms breaking down the organic matter of the dead organism.

These microorganisms, such as bacteria and fungi, release enzymes that break down the complex organic compounds into simpler compounds, which are then used as nutrients by other living organisms in the environment.

During decomposition, organic matter is broken down into carbon dioxide, water, and various minerals. The decomposition process is usually broken down into four stages: fresh, bloat, active decay, and advanced decay. During the fresh stage, the dead organism loses heat and rapidly cools. During the bloat stage, gases are produced by anaerobic bacteria, causing the body to swell. During active decay, the body is broken down by bacteria and fungi, and the process of liquefaction occurs. During advanced decay, the remains become dry and are no longer recognizable as a living organism.

The decomposition process is crucial for nutrient cycling in ecosystems, as the nutrients that are released from the dead organism are used by other living organisms. In addition, the decomposition process helps to reduce the amount of organic matter in the environment, preventing the buildup of waste.

For several decades, vitamin D has been added to milk to help increase intake of this nutrient. But in some ethnic groups, this strategy is not working. This might be due to lactose intolerance.

Lactose intolerance is the inability to digest lactose, which is a sugar that is found in milk and other dairy products. The lactase enzyme, which breaks down lactose, is not produced in sufficient amounts by people who are lactose intolerant. This can lead to digestive problems such as bloating, diarrhea, and gas. This may cause those people to avoid dairy products, which are one of the main sources of vitamin D.

As a result, they may not get enough vitamin D from their diet. In addition, some ethnic groups may also have darker skin, which can reduce their ability to produce vitamin D from sunlight. This is because melanin, which is responsible for skin pigmentation, can block the production of vitamin D in the skin.

Alkali denaturation refers to the process of using alkaline conditions to denature double-stranded DNA. In this method, DNA is treated with a strong alkaline solution, such as sodium hydroxide (NaOH), to break the hydrogen bonds between the two strands of DNA, resulting in single-stranded DNA.

The organic method is a common approach used to purify DNA from biological samples. The general steps involved in the organic method are as follows:

Cell lysis: The biological sample is treated with a lysis buffer to break open the cells and release the DNA.

Protein removal: Proteins are denatured and removed from the DNA using organic solvents such as phenol and chloroform. These solvents separate the DNA from proteins, lipids, and other contaminants.

Precipitation: DNA is precipitated by adding a cold alcohol, typically ethanol or isopropanol. The DNA forms a visible pellet that can be collected by centrifugation.

Washing: The DNA pellet is washed with ethanol to remove residual contaminants

Re-suspension: The purified DNA pellet is dissolved in a suitable buffer, such as TE buffer or distilled water, to make it ready for downstream applications.
