Mitochondria is referred to as the "powerhouse of the cell" because it is responsible for producing the majority of the cell's energy in the form of adenosine triphosphate (ATP) through cellular respiration. ATP is the main energy currency of the cell and is essential for various cellular processes such as metabolism, growth, and movement. Mitochondria have their own DNA and can replicate independently within the cell, further supporting their role as the power generators of the cell.

Yes cell is basic structural and functional unit of our body

The plasma membrane is semipermeable because it allows certain substances to pass through while restricting others. This selectivity is crucial for maintaining cellular homeostasis and regulating the movement of molecules in and out of the cell. The membrane is composed of a lipid bilayer with embedded proteins that control the transport of ions, nutrients, and waste products. This property enables the cell to control its internal environment and ensure the proper functioning of cellular processes.

In angina pectoris, ischemia is produced due to a lack of oxygen to the cardiac muscle. Ischemia refers to a reduced blood flow to a particular area, which leads to a decreased supply of oxygen. Angina pectoris is a condition characterized by chest pain or discomfort caused by a temporary reduction in blood flow to the heart muscle. This reduced blood flow is typically a result of narrowed or blocked coronary arteries, leading to insufficient oxygen supply to the cardiac muscle. Therefore, the statement "In angina pectoris, ischemia is produced due to lack of oxygen to cardiac muscle" is true.

The cerebrum is responsible for processing sensory information, including the perception of pain, touch, and temperature. It is the largest part of the brain and is divided into two hemispheres. The sensory cortex, located in the cerebrum, receives and interprets sensory signals from different parts of the body. Therefore, it is correct to say that the perception of pain, touch, and temperature is a function of the cerebrum.

Leukemia is the correct answer because it refers to an abnormal increase in white blood cell (WBC) count. Leukemia is a type of cancer that affects the bone marrow and results in the overproduction of abnormal white blood cells. This condition can lead to various symptoms such as fatigue, frequent infections, and easy bruising or bleeding. Ischemia refers to a lack of blood supply to a specific organ or tissue, thrombocytopenia refers to a low platelet count, and scurvy is a vitamin C deficiency.

Night blindness is a condition characterized by difficulty seeing in low light or darkness. The correct answer, Vitamin A, is essential for maintaining good vision and is specifically responsible for the production of a pigment called rhodopsin, which is necessary for vision in dim light. A deficiency in Vitamin A can lead to a decrease in rhodopsin production, resulting in night blindness.

Ribosomes are called the site for protein synthesis because they are responsible for translating the genetic information from the mRNA into proteins. They are composed of RNA and proteins and are found in the cytoplasm of the cell. Ribosomes read the mRNA molecule and use it as a template to assemble amino acids into a polypeptide chain, which eventually folds into a functional protein. Therefore, ribosomes play a crucial role in the production of proteins, which are essential for various cellular processes and functions.

Blood is the correct answer because it is a fluid connective tissue that circulates throughout the body, delivering oxygen and nutrients to cells and removing waste products. It is composed of red and white blood cells, platelets, and plasma. Blood plays a crucial role in maintaining homeostasis, regulating body temperature, and defending against infections. It is also involved in transporting hormones, enzymes, and other substances throughout the body.

A decrease in platelet count can lead to various complications such as blood loss, delay in blood clotting, and hemorrhage. Platelets are responsible for forming blood clots to stop bleeding. When the platelet count is low, the blood clotting process is impaired, resulting in delayed clot formation. This can lead to prolonged bleeding, which can cause blood loss and hemorrhage. Therefore, all of the given options are correct consequences of a decrease in platelet count.

The tympanic membrane, also known as the eardrum, plays a crucial role in hearing. It vibrates when sound waves enter the ear, transmitting these vibrations to the middle ear and ultimately to the inner ear where they are converted into electrical signals that the brain can interpret as sound. If the tympanic membrane is damaged, it may not be able to vibrate properly, resulting in hearing loss. Therefore, it is true that damage to the tympanic membrane can be responsible for hearing loss.

Shoulder joint is example of ball and socket joint

Plant cells have more vacuoles compared to animal cells. Vacuoles are membrane-bound organelles that are responsible for storing water, nutrients, and waste materials. In plant cells, vacuoles are larger and more prominent, occupying a significant portion of the cell's volume. They play a crucial role in maintaining turgidity and providing structural support to the plant. Vacuoles in plant cells also store pigments, toxins, and other substances. In contrast, animal cells generally have smaller and fewer vacuoles, which are primarily involved in storing water and waste materials.

Pernicious anemia is caused by a deficiency of intrinsic factor. Intrinsic factor is a protein produced by the stomach that is necessary for the absorption of vitamin B12. Without intrinsic factor, vitamin B12 cannot be properly absorbed by the body, leading to a deficiency and subsequent anemia.

Progesterone is the correct answer because it is the hormone that prepares the endometrium for implantation of a fertilized ovum. Progesterone is produced by the ovaries after ovulation and helps to thicken the lining of the uterus, making it more receptive to the fertilized egg. It also helps to maintain the pregnancy by preventing the shedding of the uterine lining.

Absorption of protein and lipids takes place in small intestine

The skull joint is an example of an immovable joint because the bones of the skull are tightly fused together, allowing for no movement. This joint provides protection to the brain and stability to the head. Unlike other joints, such as the shoulder joint, which allows for a wide range of movement, the skull joint is fixed and does not permit any motion.

Eukaryotic cells are present in multicellular organisms because multicellular organisms are composed of multiple cells that have a nucleus and other membrane-bound organelles, which are characteristics of eukaryotic cells. Unicellular organisms, such as bacteria, usually have prokaryotic cells, which lack a nucleus and membrane-bound organelles. Viruses, on the other hand, are not considered to be cells at all, as they are acellular and cannot replicate on their own. Therefore, the correct answer is multicellular organism.

Renin is a hormone secreted by the kidney. It plays a crucial role in regulating blood pressure and fluid balance in the body. Renin is released in response to low blood pressure, low blood volume, or low sodium levels. It acts on angiotensinogen, a protein produced by the liver, to convert it into angiotensin I. This is then converted to angiotensin II, a potent vasoconstrictor that increases blood pressure. Overall, renin secretion by the kidney helps maintain blood pressure within a normal range and ensures proper fluid balance in the body.

Oxytocin is secreted by posterior lobe of pituitary gland

Amylase do digestion of carbohydrates

Insulin is secreted by pancreas

Mineralocorticoid is secreted by adrenal cortex



 

Diuresis refers to an increase in urine output, not a decrease. When diuresis occurs, the kidneys produce and excrete larger volumes of urine, leading to increased fluid loss from the body. Therefore, the statement "diuresis means decrease in urine output" is false.

Colour of muscle of iris is responsible for colour of eye like black,brown eye

The cerebellum is responsible for the maintenance of balance. It receives information from the sensory systems, such as the inner ear and muscles, and coordinates movements to ensure that the body remains upright and stable. Damage to the cerebellum can result in difficulties with balance, coordination, and motor control.

Menopause is the cessation or stopping of the menstrual cycle. During menopause, a woman's ovaries stop releasing eggs and her hormone levels, including estrogen and progesterone, decline. This leads to the end of menstruation and fertility. Menopause typically occurs in women between the ages of 45 and 55, but can happen earlier or later. Symptoms of menopause can include hot flashes, night sweats, mood changes, and vaginal dryness.
