  • Question 1
    1 / -0
    Hypotension may not be due to _______.
  • Question 2
    1 / -0
    Which one represents pulmonary circulation?
    Solution
    Pulmonary circulation is the flow of deoxygenated blood to lungs and return of oxygenated blood to the heart. 
    • Deoxygenated blood from the body parts is brought to right auricle by the vena cava. 
    • The blood is pumped to the right ventricle from the right auricle. 
    • From the right ventricle, deoxygenated blood is carried to lungs by pulmonary artery. 
    • The blood gets mixed with oxygen in the lungs and is carried to left auricle of heart by pulmonary vein. 
    So, the correct answer is 'Right auricle (deoxygenated blood) →→ lungs (oxygenated blood) →→ Left auricle'.
  • Question 3
    1 / -0
    The cells surrounding the stomata are known as
    Solution
    The cell surrounding the stomata is known as guard cells. They are two highly specialized cells. They are dumbbell shaped in grasses and Kidney-shaped in dicotyledons. They have nucleus, chloroplasts, starch grains, mitochondria, endoplasmic reticulum, Golgi apparatus, and ribosomes. They regulate the rate of transpiration by opening and closing the stomata. 
    Thus, the correct answer is option A.
  • Question 4
    1 / -0
    Blood vessel which brings oxygenated blood to left auricle is:
    Solution
    A. Anterior vena cava carries deoxygenated blood from anterior body parts to the right auricle.
    B. Posterior vena cava carries deoxygenated blood from posterior body parts to the right auricle.
    C. Pulmonary vein carries oxygenated blood from the lungs to the left auricle.
    D. Pulmonary artery carries deoxygenated blood from the right ventricle to the lungs.
    So, the correct answer is option C.
  • Question 5
    1 / -0
    The part of the cardiovascular system that transports oxygen-depleted blood from the heart to the lungs brings oxygenated blood back to the heart is:
    Solution
    The correct answer is option A. 
    • The cardiovascular system is composed of two circulatory paths: pulmonary circulation, the circuit through the lungs where blood is oxygenated; and systemic circulation, the circuit through the rest of the body to provide oxygenated blood. The two circuits are linked to each other through the heart, creating a continuous cycle of blood through the body.  
    • Pulmonary circulation: The part of blood circulation which carries oxygen-depleted blood away from the heart, to the lungs, and returns oxygenated blood back to the heart. 
    •  Systemic circulation: The part of blood circulation that carries oxygenated blood away from the heart, to the body, and returns deoxygenated blood back to the heart.
  • Question 6
    1 / -0
    Sphygmomanometer is an instrument that is used to record:
    Solution
    The pressure of blood inside the artery during ventricular contraction is called systolic pressure and pressure in the artery during ventricular relaxation is called diastolic pressure. 
    Both systolic and diastolic pressure can be recorded by a sphygmomanometer.
    The normal systolic pressure is about 120 mm of Hg and diastolic pressure is 80 mm of Hg.
    So, the correct answer is option D.
  • Question 7
    1 / -0
    If blood pressure reads 140 systole and 90 diastole, the condition is called
    Solution
    Normal range of systolic pressure is between 90 and less than 120 and diastolic pressure id between 60 and less than 80.
    If the blood pressure reads 140 systole and 90 diastole, then the condition is known as high blood pressure. Another name of high blood pressure is hypertension.
    So the correct answer will be option A.
  • Question 8
    1 / -0
    The most important process for the existence of life on Earth is:
    Solution
    Photosynthesis is the most important process on earth, without which neither plants nor animals can survive. Plants get their own food through the process of photosynthesis. The energy stored in organic molecules of the plants is the fuel of life for most living organisms. The oxygen released in the process of photosynthesis is used by most of the living organisms for respiration. 
    So, the correct option is C.
  • Question 9
    1 / -0
    Artery is a vessel that carries blood
    Solution
    Arteries are the vessels which carry oxygenated blood pumped from the heart to various organs, tissues and cells of the body.
  • Question 10
    1 / -0
    It is a byproduct during carbon assimilation by a plant.
    Solution
    Oxygen produced by the plant during carbon assimilation is a byproduct. The plant utilizes solar energy in the process of photosynthesis and produces cellular material by utilizing CO$$_2$$ and H$$_2$$O. During respiration, stored food is oxidized into CO$$_2$$ and water and energy is released. 
    Thus, the correct answer is option D.
