Homeostasis is defined as the regulation of biological systems such as temperature, blood pressure, etc., in response to changing environmental conditions. Sweating is an example of homeostasis as it helps regulate our body temperature. When our core temperature rises, we start to sweat.
In biology, homeostasis (British also homoeostasis) is the state of steady internal, physical, and chemical conditions maintained by living systems This is the condition of optimal functioning for the organism and includes many variables, such as body temperature and fluid balance, being kept within certain pre-set limits (homeostatic range).
Other variables include the pH of extracellular fluid, the concentrations of sodium, potassium and calcium ions, as well as that of the blood sugar level, and these need to be regulated despite changes in the environment, diet, or level of activity. Each of these variables is controlled by one or more regulators or homeostatic mechanisms, which together maintain life

How are genes organized in DNA?
Typically, the genes are organized in DNA in the form of chromosomes. Chromosomes are structures that resemble threads and are found inside the nucleus of plant and animal cells.
A gene is the fundamental physical and useful unit of heredity. DNA is what makes up genes. Some genes serve as instructions for making proteins, which are molecules. However, a lot of genes don't make proteins.
Genes are found on these chromosomes. Protein and a single molecule of deoxyribonucleic acid (DNA) make up each chromosome. DNA contains the specific instructions that give each living thing its individuality and are passed down from parents to children. Chromosomes, which are made up of long strands of DNA, contain many genes. Each gene has its own locus (plural locus) on the chromosome, and each chromosome has its own sequence of genes.

What causes a point mutation?
The point mutation arises due to errors in the replication of DNA.
The single base pair in the DNA sequence that is altered in a point mutation. This may induce changes in gene expression. Although DNA alteration, for as by exposure to X-rays or UV radiation, can also cause point mutations, mistakes occurred during DNA replication are most usually the cause of point mutations.
Transition mutations and transversion mutations are the two different forms of point mutations. Transition mutations happen when a purine base replaces another purine base or when a pyrimidine base replaces another pyrimidine base. Transversion mutations, on the other hand, take place when a pyrimidine base is changed into a purine base or vice versa.
Hence, point mutation is single base pair change which alter protein structure.

Does Type B blood make antibodies against type A?
Type B blood does make antibodies against Type A. However, the production of antibodies does not guarantee immunity, and it is possible for Type B individuals to develop antibodies against their own type of blood.
Type A and Type B blood are the two major categories of human blood groups. Each type is classified based on the presence or absence of two antigens, A and B, on the surface of red blood cells. As such, it is possible for an individual to possess either type A, type B, or both antigens.
Due to the fact that the A and B antigens are distinct from each other, and the body’s immune system recognizes the difference. When exposed to the A antigen, a Type B blood group individual will produce antibodies that recognize and attach to the A antigen, thus helping to protect the body against disease.
Furthermore, it is possible for Type B individuals to develop antibodies against their own type of blood, if they have been exposed to a transfusion of Type A blood.

List the significant events of the Electron Transport Chain. Include which reactants and products are involved. Highlight what will be released as a product. Be sure to include where the process occurs in the mitochondria.
Answer:
The electron transport chain is a series of protein complexes and electron carriers that are located in the inner membrane of the mitochondria. These complexes and carriers are involved in the transfer of electrons from NADH and FADH2, produced during glycolysis and the Krebs cycle, to oxygen, the final electron acceptor. The energy released from this transfer is used to pump protons across the inner mitochondrial membrane, generating a proton gradient that drives the production of ATP.
The key events of the electron transport chain include the following:
The transfer of electrons from NADH to complex I, also known as NADH-ubiquinone oxidoreductase, by the enzyme NADH dehydrogenase. This complex consists of several protein subunits and a non-protein electron carrier called ubiquinone.
The transfer of electrons from complex I to complex II, also known as succinate-ubiquinone oxidoreductase or succinate dehydrogenase, by the enzyme ubiquinone. Complex II consists of several protein subunits and a non-protein electron carrier called ubiquinone.
The transfer of electrons from complex II to complex III, also known as ubiquinone-cytochrome c oxidoreductase or cytochrome bc1 complex, by the enzyme cytochrome b. Complex III consists of several protein subunits and two non-protein electron carriers called cytochromes c1 and c.
The transfer of electrons from complex III to complex IV, also known as cytochrome c oxidase or cytochrome aa3, by the enzyme cytochrome c. Complex IV consists of several protein subunits and two non-protein electron carriers called cytochromes a and a3.
The transfer of electrons from complex IV to oxygen by the enzyme cytochrome a3. Oxygen is the final electron acceptor in the electron transport chain.
As the electrons are transferred through the complexes of the electron transport chain, energy is released and used to pump protons across the inner mitochondrial membrane. This creates a proton gradient that drives the synthesis of ATP by the enzyme ATP synthase. The end products of the electron transport chain are water and ATP.
Explanation:
