B. alveolus
C. urethra
D. nephron
Ans. (D). nephron.
Kidneys are bean-shaped organs of excretory system that make urine and help in elimination of wastes from the body. Nephrons can be defined as structural and functional units of kidneys, made up of renal tubes and renal capsules.
Process of filtration, re-absorption, and secretion take place in nephrons to filter blood, make urine and excrete waste products out from the body with urine.
Thus, the correct answer is option (D).
The functional unit of the kidney involved in the filtration, reabsorption, and excretion processes is called the nephron.
The functional unit of the kidney where blood is filtered, water and other dissolved substances are reabsorbed, and waste is sent out to be excreted is the nephron.
Each kidney in the human body contains about one million nephrons. The nephron is a tiny tubular structure composed of a renal corpuscle (which is the site for blood filtration), and a renal tubule (where reabsorption occurs). Waste from this filtration is then collected and departs the kidney through the ureter, to be excreted from the body as urine.

The distribution of the native indigenous population of human to a wildlife habitat is a common practice seen among the villagers and has also been adapted by the urban societies . They move to forests in search of habitat, obtaining fuel food cooking food and for other needs. This displacement has affected the wildlife considerably. The animals which are dislocated from their natural habitats often found to be located in urban areas where they can become threat to the lives of the human lives and for themselves.
Nonrenewable resources like oil, natural gas, and coal are efficient and economically viable due to established infrastructure. However, they have environmental impacts and are finite.
The question asks about the advantages of using nonrenewable resources. Nonrenewable resources such as oil, natural gas, and coal, have several advantages. One significant advantage of nonrenewable resources is their efficiency. These types of resources are often much more efficient in generating energy than renewable alternatives. For example, a small amount of coal or nuclear energy can produce substantially more energy than solar or wind power. Furthermore, nonrenewable resources are currently more economically viable. The infrastructure for extracting and using these resources is well established, making them cheaper to use in the short term as compared to renewable sources. However, we need to be aware of the environmental impact and the fact that these resources are finite and will eventually run out.

b. area of square c2 = area of square a2 + area of square b2 + area of defect1 – area of defect2
c. area of square c2 = area of square a2 + area of square b2 – area of defect1 – area of defect2
d. area of square c2 = area of square a2 + area of square b2 + area of defect1+ area of defect2
e. area of square c2 = area of square a2 - area of square b2 + area of defect1 - area of defect2
Answer: c. area of square c2 = area of square a2 + area of square b2 – area of defect1 – area of defect2
(Option C)
Explanation:
The cosine rule helps to determine the different angles and sides of a triangle. The cosine rule is helpful when you need to find the third side of the triangle when the other two sides of the triangle are given and the angle between them.
The use of steamis essential in most power plants. Water is heated and dispatched through aturbine creating thermal energy. Later on, it is converted to electricity. Thesteam enables the turbines to rotate which activates a generator, producingelectricity.
