Which one is not the feature of solids?

A. Definite Mass and Volume
B. Frequent Fludity
C. Rigidity
D. Definite Shape



Answer & Solution
Option: B
Explanation : Solid is one of the states of matter

  • Solid have Definite mass, volume, and shape because particles of matter are held together by strong intermolecular forces.
  • Solid have Short Intermolecular distance due to tight close packing.
  • Strong Intermolecular Forces because atoms and molecules are held close together.
  • Solids are incompressible and rigid in nature due to strong intermolecular forces acting on particles which keep them fixed on their positions.

      A. Vitamin A
      B. Vitamin B
      C. Vitamin C
      D. Vitamin D

      Answer & Solution
      Option: D
      Explanation :We can get Vitamin D from sun rays. We also get vitamin D from a foods like oily fish, red meat and eggs. Vitamin D deficiency cause bones to become soft and weak. In children vitamin D deficiency lead to rickets. In adults it lead to osteomalacia which causes bone pain and tenderness.

          If a man have blood group A then he can receive blood from person having blood group

          A. AB+, O+
          B. A+, O-
          C. A+, O+
          D. None of these

          Answer & Solution
          Option: C
          Explanation :Your blood type is determined by the antigens it contains. There are two major types of blood antigens: ABO and Rh, which combine to create blood types: O+. O-, A+, A-, B+, B-, AB+ & AB-
          A patient can receive blood that has the same ABO antigens as theirs, plus O. Rh+ can receive Rh+ or Rh-, while Rh- must receive Rh- blood.
          If your blood type is: O Positive You can give to: O+, A+, B+, AB+ You can receive from: O+, O-
          If your blood type is: A Positive You can give to: A+, AB+ You can receive from: A+, A-, O+, O-
          If your blood type is: B Positive You can give to: B+, AB+ You can receive from: B+, B-, O+, O-

            Which of the following enzymes is present in the Saliva?

            A. Ptyalin
            B. Bile
            C. Trypsin
            D. Lipases

            Answer & Solution
            Option: A
            Explanation :Ptyalin is an enzyme that is part of your saliva and aids with digestion. Enzymes are compounds that help speed up chemical reactions. In the case of saliva, the enzymes help speed up reactions that break down the food you eat. Even before food makes it to your stomach it begins to break down, and enzymes help make the process go smoothly.
            Ptyalin helps digestion by breaking down starches and glycogens as they enter your mouth. After the starches and glycogen are covered with saliva, they are broken down into maltose and glucose — simple sugars that can be used more readily by the body. After the ptyalin speeds up the chemical reaction that breaks down these molecules, it simply unbinds from them and binds to a different set of molecules. Ptyalin can be used again and again, and this is what allows us to continue eating starches and glycogen.

              Which one is produced by liver

              A. Ricket
              B. Blood diluteness
              C. Bile
              D. Enzymes

              Answer & Solution
              Option: C
              Explanation :A biliary obstruction is a blockage of the bile ducts. The bile ducts carry bile from the liver and gallbladder through the Pancreas to the duodenum (Parts of the small intestine). Bile is a dark green or Yellowish brown fluid secreted by the liver to digest fats. After you eat the gallbladder releases bile to help in digestion and fat absorption. Bile also helps clear the liver of waste products.

                The seat of memory in the human brain is located in the

                A. Cerebellum
                B. Cortex
                C. Cerebrum
                D. All of these




                Answer & Solution
                Option: D
                Explanation :Seat of memory in human brain is located in Cerebellum, Cortex and Cerebrum. The Cerebrum is one correct answer, but it’s the cerebral cortex where that memory is held. So cortex is also a correct answer. On the other hand cerebellum holds other kinds off-memory, so that’s correct answer too.
                The human brain is hugely interconnected but three major components can be identified:
                I. The cerebrum
                II. The cerebellum
                III. The brain stem
                Role of Cerebellum:-
                The cerebellum plays an important role in balance and motor control. As a result cerebellum involved in some cognitive functions such as attention, language, emotional functions and in the processing of procedural memories.
                Most importantly the cerebrum (or forebrain) makes up 75% of the brain by volume and 85% by weight. It is divided by a large groove, known as the longitudinal fissure, into two distinct hemispheres. The left and right hemispheres (“left” and “right” refer to the owner’s point of view, not an outside viewer’s) are linked by a large bundle of nerve fibres called the corpus callosum, further also by other smaller connections called commissures.
                The cerebrum is covered by a sheet of neural tissue known as the cerebral cortex (or neocortex). Cerebral cortex envelops other brain organs such as the thalamus, the hypothalamus and pituitary gland.
                Firstly thalamus evolved to help relay information from the brain stem and spinal cord to the cerebral cortex. Secondly pituitary gland control visceral functions, body temperature and behavioural responses such as feeding, drinking, sexual response, aggression and pleasure.
                Role of Cerebral Cortex:-
                The cerebral cortex plays a key role in memory, attention, perceptual awareness, thought, language and consciousness. It is divided into four main regions or lobes, which cover both hemispheres.
                The frontal lobe involved in conscious thought and higher mental functions such as decision-making, particularly. This part of the frontal lobe known as the prefrontal cortex. In addition prefrontal cortex plays an important part in processing short-term memories and retaining longer term memories. Therefore The seat of memory in the human brain is located in Cerebellum, Cortex, Cerebrum

                  Number of bones in the human body of an adult is

                  A. 202
                  B. 204
                  C. 206
                  D. 208

                  Answer & Solution
                  Option: C
                  Explanation :The human skeleton is the internal framework of the human body. It is composed of around 270 bones at birth – this total decreases to around 206 bones by adulthood after some bones get fused together. The bone mass in the skeleton reaches maximum density around age 21. The human skeleton can be divided into the axial skeleton and the appendicular skeleton. The axial skeleton is formed by the vertebral column, the rib cage, the skull and other associated bones. The appendicular skeleton, which is attached to the axial skeleton, is formed by the shoulder girdle, the pelvic girdle and the bones of the upper and lower limbs.
                  The human skeleton performs six major functions; support, movement, protection, production of blood cells, storage of minerals, and endocrine regulation.

                    Oncology is the study of

                    A. Animals
                    B. Plants
                    C. Lungs
                    D. Cancer

                    Answer & Solution
                    Option: D
                    Explanation :Oncology is the study of cancer. An oncologist is a doctor who treats cancer and provides medical care for a person diagnosed with cancer. The field of oncology has three major areas: medical, surgical, and radiation.
                    A medical oncologist treats cancer using chemotherapy or other medications, such as targeted therapy or immunotherapy.
                    A surgical oncologist removes the tumor and nearby tissue during surgery. He or she also performs certain types of biopsies to help diagnose cancer.
                    A radiation oncologist treats cancer using radiation therapy.
                    An oncologist manages a patient’s care throughout the course of the disease. This starts with the diagnosis. His or her role includes:

                  • I. Explaining the cancer diagnosis and stage
                    II. Talking about all treatment options and his or her preferred choice
                    III. Delivering quality and compassionate care
                    IV. Helping a patient manage the symptoms and side effects of cancer and cancer treatment.
