C. nephrons

Download to view full explanation
In the kidney, the structures that filter the blood are the nephrons. Nephrons are the functional units of the kidney responsible for filtering waste products, excess water, and other substances from the blood to form urine. Each kidney contains millions of nephrons, which consist of a glomerulus and a tubule. The glomerulus acts as a filter, allowing small molecules such as water, electrolytes, and waste products to pass through while retaining larger molecules like proteins and blood cells. The filtered fluid then passes through the tubule, where reabsorption of essential substances and further concentration of urine occur. Ultimately, the nephrons play a crucial role in maintaining the body's fluid balance, electrolyte levels, and waste elimination through the process of filtration, reabsorption, and secretion.

Question
1. vvily Oran it oecorrie
necessary to
distinguish between
organic chemistry
and inorganic
chemistry? Explain
the reasons for this
division and its
importance today.
Answer

Organic chemistry and inorganic chemistry are divided because they involve different types of compounds. Organic chemistry involves compounds that contain carbon, while inorganic chemistry involves compounds that do not contain carbon. This division is important today because it allows chemists to study and understand the different properties of each type of compound.

Download to view full explanation
Organic chemistry is the study of compounds that contain carbon, such as proteins, carbohydrates, and lipids. Inorganic chemistry is the study of compounds that do not contain carbon, such as metals, salts, and acids. This division is important because it allows chemists to study and understand the different properties of each type of compound. For example, organic compounds tend to be more complex and have different reactivity than inorganic compounds. This division also allows chemists to develop new compounds and materials that have specific properties and applications.
