Select the correct option which is related to the movement of food through esophagus.
-
Lubrication by saliva
-
Peristalsis
-
Gravitational Pull
-
All of the above
Correct Answer
A. PeristalsisExplanation
Peristalsis is the correct option related to the movement of food through the esophagus. Peristalsis refers to the rhythmic contractions of the muscles in the esophagus that push food towards the stomach. This process allows food to move through the esophagus in a coordinated and efficient manner, ensuring that it reaches the stomach for digestion. Lubrication by saliva and gravitational pull are not directly involved in the movement of food through the esophagus, making peristalsis the most appropriate answer.Rate this question:

Bile, involved in the emulsification and digestion of fats, is produced by?
-
Gall bladder
-
Blood
-
Liver
-
Spleen
Correct Answer
A. LiverExplanation
Bile is involved in the emulsification and digestion of fats. It breaks down large fat molecules into smaller ones, making it easier for enzymes to digest them. The liver produces bile, which is then stored and concentrated in the gallbladder before being released into the small intestine during digestion. Therefore, the correct answer is liver.Rate this question:

Select the correct system which can relate to the function of the kidney.
-
Nutrition
-
Respiration
-
Excretion
-
Transportation
Correct Answer
A. ExcretionExplanation
The correct system that relates to the function of the kidney is excretion. The kidney is a vital organ in the excretory system, responsible for filtering waste products, toxins, and excess water from the blood to form urine. It helps maintain the body's fluid balance, regulate blood pressure, and eliminate metabolic waste products such as urea and creatinine. The excretory system also includes other organs like the bladder and ureters, which work together with the kidneys to eliminate waste from the body.Rate this question:

The xylem in plants are responsible for
-
Transport of water from roots of the plants
-
Transport of food
-
Transport of water from stomata to the root of the plants
-
Transport of oxygen
Correct Answer
A. Transport of water from roots of the plantsExplanation
The xylem in plants is responsible for the transport of water from the roots of the plants. Xylem is a complex tissue composed of specialized cells that form a network of tubes. These tubes allow water to move upwards from the roots to the rest of the plant. This process, known as transpiration, is essential for the plant's survival as it provides water and nutrients to all parts of the plant, including the leaves, stems, and flowers. Without the xylem, plants would not be able to absorb water efficiently, leading to dehydration and ultimately death.Rate this question:

The autotrophic mode of nutrition is a characteristic feature of plants that requires:
-
Carbon dioxide and water
-
Chlorophyll
-
Sunlight
-
All of the above
Correct Answer
A. All of the aboveExplanation
The autotrophic mode of nutrition in plants requires all of the above mentioned factors. Plants use carbon dioxide and water to undergo photosynthesis, a process in which they convert sunlight energy into chemical energy with the help of chlorophyll. Therefore, all three factors are essential for plants to carry out autotrophic nutrition.Rate this question:

The diaphragm changes its shape in the process of respiration. Select the correct situation in normal expiration.
-
Arched
-
Flattened
-
Perforated
-
None of these
Correct Answer
A. ArchedExplanation
During normal expiration, the diaphragm relaxes and moves upwards, causing it to arch. This upward movement of the diaphragm reduces the volume of the thoracic cavity, increasing the pressure inside the lungs. As a result, air is forced out of the lungs, allowing for expiration to occur. Therefore, the correct situation in normal expiration is when the diaphragm is arched.Rate this question:

Choose the correct statement for the process of respiration
-
Energy is stored in the form of ADP
-
Energy is released and stored in the form of ATP
-
Energy is used up
-
Energy is not released at all
Correct Answer
A. Energy is released and stored in the form of ATPExplanation
During the process of respiration, energy is released and stored in the form of ATP (adenosine triphosphate). ATP is a molecule that carries energy within cells and is used as a source of energy for various cellular processes. Through the breakdown of glucose and other molecules, energy is released and stored in ATP molecules, which can then be used by the cell for activities such as muscle contraction, active transport, and synthesis of molecules.Rate this question:

Give a term for the action of bile from the below options
-
Esterification
-
Hydrogenation
-
Oxidation
-
Emulsification
Correct Answer
A. EmulsificationExplanation
Emulsification is the term used to describe the action of bile. Bile is a substance produced by the liver and stored in the gallbladder, and it plays a crucial role in the digestion and absorption of fats. Emulsification refers to the process of breaking down large fat globules into smaller droplets, increasing their surface area and making them easier to digest. Bile acts as an emulsifying agent by surrounding the fat droplets and preventing them from clumping together. This allows for the efficient breakdown and absorption of fats in the small intestine.Rate this question:

An organism that can live without oxygen or air?
-
Amoeba
-
Sheep
-
Yeast
-
Leech
Correct Answer
A. YeastExplanation
Yeast is a correct answer because it is a type of fungus that can carry out fermentation, a process that does not require oxygen. Yeast can survive and reproduce in environments with low or no oxygen, making it an organism that can live without oxygen of air. Amoeba, sheep, and leech are not capable of surviving without oxygen.Rate this question:

A long small intestine is the characteristic feature of?
-
Carnivores
-
Omnivores
-
Herbivores
-
Autotroph
Correct Answer
A. HerbivoresExplanation
Herbivores have longer small intestines compared to carnivores and omnivores because they consume plant material which is more difficult to digest and requires more time for processing. The longer length allows for a slower digestion process and more efficient absorption of nutrients from the plant matter. This adaptation helps herbivores extract as much nutrition as possible from their plant-based diet.Rate this question:

Identify the correct location for villi
-
Pancreas
-
Stomach
-
Small intestine
-
Esophagus
Correct Answer
A. Small intestineExplanation
Villi are tiny, finger-like projections that line the inner walls of the small intestine. These structures greatly increase the surface area of the small intestine, allowing for more efficient absorption of nutrients from digested food. The pancreas, stomach, and esophagus do not have villi. Therefore, the correct location for villi is the small intestine.Rate this question:

-
Vena cava
-
Pulmonary vein
-
Pulmonary artery
-

Identify the statement which justifies the process of respiration
-
Energy is stored in the form of ADP
-
Energy is used up
-
Energy is released and stored in the form of ATP
-
Energy is not released at all
Correct Answer
A. Energy is released and stored in the form of ATPExplanation
The statement "Energy is released and stored in the form of ATP" justifies the process of respiration because respiration is the process by which cells break down organic molecules, such as glucose, to release energy. This energy is then stored in the form of ATP (adenosine triphosphate), which is the primary energy molecule used by cells. Therefore, the statement accurately describes the role of ATP in respiration and how energy is both released and stored during this process.Rate this question:

Select the correct pathway of blood in circulatory system.
-
Atria ……> ventricles ……> arteries ……> veins
-
Ventricles ……> atria ……> veins ……> arteries
-
Ventricles ……> veins ……> arteries ……> atria
-
Veins ……> ventricles ……> atria ……> arteries
Correct Answer
A. Atria ……> ventricles ……> arteries ……> veinsExplanation
The correct pathway of blood in the circulatory system starts with the atria, which receive blood from the body and the lungs. From the atria, the blood flows into the ventricles, which are the lower chambers of the heart. The ventricles then contract and pump the blood into the arteries, which carry oxygenated blood away from the heart to the rest of the body. Finally, the blood returns to the heart through the veins, which carry deoxygenated blood back to the atria.Rate this question:
