(i) Carbohydrates, lipids, and proteins are completely digested in the small intestine. For this function, it receives the liver and the pancreas secretions.(ii) For pancreatic enzymes to work on stomach-born food, they must be converted from their naturally acidic state to an alkaline one. This is done with the help of bile juice, which the …

The breakdown of pyruvate to give carbon dioxide, water and energy take place in mitochondria. Hence, the answer is (b) mitochondria

Carbon dioxide, water, chlorophyll, and sunlight from the processing of food are necessary for the autotrophic mode of nourishment. So, (d) all of the above is the correct response.

In plants, the Xylem is responsible for the transport of water. Hence, the answer is (a)

The answer is (c) excretion The human excretory system consists of two kidneys, two ureters, a urinary bladder, and a urethra. There are two kidneys in the abdomen, one on each side of the vertebrae. The urinary bladder is where the urine that is produced in the kidneys is stored until it is released through …

The quantity of extra water and dissolved waste that is present in the body affects how much urine is generated. The ADH hormone, which regulates urine production, and the environment may also be contributing factors.

Transpiration is a method for plants to eliminate excess water. Plants contain the fact that a lot of their tissues are made up of dead cells and that they can even lose some sections, like leaves, to help with other wastes. Vacuoles within cells are where a lot of plant waste is kept. Waste materials …

Nephrons are the filtration units of the kidney, which are large in numbers. As the urine moves down the tube, certain components of the original filtrate, including glucose, amino acids, salts, and a significant amount of water, are selectively reabsorbed. The main components of Nephrons are Glomerulus Bowman’s Capsule Long Renal Tube Structure of Nephron …

A special organ in plants called the phloem is responsible for moving food. Food components are transported from leaves to various areas of a plant by phloem. The movement of food through the phloem requires the use of ATP’s energy. Water moves as a result of an increase in osmotic pressure in the tissue. With …

 Plants parts of the plant are connected by a continuous network of water-conducting channels thought up of the xylem components of the tracheids and the vessels of the roots, stems, and leaves. Suction pressure from transpiration forces water into the xylem cells of roots. From the root xylem to all areas of the plant connected …
