Q 27. Which of the following function is performed by the kidneys in the human body?
मानव शरीर के गुर्दे इनमे से कौन सा कार्य करते हैं?
SSC CGL 9-august-2017
1.Excretion उत्सर्जन
2.Respiration श्वसन
3.Digestion पाचन
4.Transportation परिवहन
Correct Answer: Excretion उत्सर्जन
Basic functions of kidneys include:
1. Regulation of pH. The kidneys prevent blood plasma from becoming too acidic or basic by regulating ions.
2. Excretion of wastes and toxins. The kidneys filter out a variety of water-soluble waste products and environmental toxins into the urine for excretion.
3. Production of hormones. The kidneys produce erthryopoietin, which stimulates red blood cell synthesis, and renin, which helps control salt and water balance and blood pressure. They are also involved in regulating plasma calcium and glucose levels.
4. Regulation of extracellular fluid volume. The kidneys work to ensure an adequate quantity of plasma to keep blood flowing to vital organs.
5. Regulation of osmolarity. The kidneys help keep extracellular fluid from becoming too dilute or concentrated with respect to the solutes carried in the fluid.
6. Regulation of ion concentrations. The kidneys are responsible for maintaining relatively constant levels of key ions including sodium, potassium and calcium.

Q 30. Plant tissues are of how many types?
पौधों के उत्तक कितने प्रकार के होते हैं?
[SSC CGL 9-08-17]
Correct Answer: 3
Plants have only three tissue types: 1) Dermal; 2) Ground; and 3) Vascular. Dermal tissue covers the outer surface of herbaceous plants. Dermal tissue is composed of epidermal cells, closely packed cells that secrete a waxy cuticle that aids in the prevention of water loss. Vascular tissue – The primary components of vascular tissue are the xylem and phloem.>
