Answer:
The oxygen molecule enters the human body from the mouth or nose and reaches the phraynx and then the larynx, trachea and the bronchus. It then enters the lungs which then the red blood cells takes the oxygen from the blood and carries it to the muscle in the arm.
The pathway of an oxygen molecule from the air outside your body to a muscle cell in your arm involves several sequential steps, including inhalation, gas exchange in the lungs, transportation through the bloodstream, and diffusion into muscle cells.
During inhalation, you breathe in air through your nose or mouth. The air travels through your respiratory system, passing through the trachea (windpipe) and into the bronchi, which branch into smaller tubes called bronchioles. Eventually, the inhaled air reaches the alveoli, tiny air sacs located at the end of the bronchioles in the lungs.
In the alveoli, oxygen molecules diffuse across the thin walls of the air sacs and into the surrounding capillaries. Oxygen diffuses from an area of higher partial pressure (in the alveoli) to an area of lower partial pressure (in the capillaries). Hemoglobin, a protein within red blood cells, binds to the oxygen molecules in the capillaries, forming oxyhemoglobin.

how does an autoimmune disease affect the muscular system?
Answer:
Explanation:
Myositis (my-o-SY-tis) is a rare type of autoimmune disease that inflames and weakens muscle fibers. Autoimmune diseases occur when the body's own immune system attacks itself. In the case of myositis, the immune system attacks healthy muscle tissue, which results in inflammation, swelling, pain, and eventual weakness.

Answer:
1.Toad
2.Newt
3.Salamander
In addition to the frog, the other organisms that are classified as modern amphibians are toads and salamanders. Therefore, the correct option is A.
What are modern amphibians?Modern amphibians are a class of cold-blooded vertebrates that spend part of their life cycle in water and part on land. They are united under the taxon Lissamphibia. They are divided into three clades which are Urodela, Anura and Apoda. In addition to frogs, the other two groups of modern amphibians are toads and salamanders.
Snakes and lizards are reptiles, which are a different class of cold-blooded vertebrates. Opossums and koalas are marsupials, which are warm-blooded mammals, and sharks and skates are fish, which are cold-blooded vertebrates but are not classified as amphibians. Therefore, the correct option is A.

without rain animals would not survive
Answer:
Without rain, there would more than likely be no collection of water for animals to drink such as ponds, lakes, rivers, etc. Rain, in addition to providing these animals with water to drink, also provides them with their natural habitats such as fish, mosquitoes, and other water creatures. Without rain, animals would merely perish, and soon, humans would as well.

why would one gene work as a barcode for one species and not for another
One gene work as a barcode for one species and not for another because for different species different barcodes are used.
Every specie is different than another organism genetically so it also needs different barcodes for every other specie. If all the species are made up of the same gene then we can say that one barcode is used for all of them but its not the case.
Every organism has different and its own gene so one gene barcode is not acceptable for all species but for the original one so we can conclude that one barcode is used for one species and not for another.

Foods or beverages created through managed microbial growth and enzymatic conversion of food components are referred to as fermented foods.
What is biotechnology?Biotechnology is the application of biology to the problem-solving and product-making processes. The most well-known application of biotechnology is the use of genetic engineering to produce therapeutic proteins and other medications.
Because the production of antimicrobial metabolites (such as organic acids, ethanol, and bacteriocins) lowers the danger of contamination with pathogenic bacteria, food fermentation has historically been used as a preservation technique.
Therefore, Foods or beverages created through managed microbial growth and enzymatic conversion of food components are referred to as fermented foods.
