this is biology que can any one solve it.​

Answer 1

1.The first step in urine formation is also known as ultrafiltration. This process starts in glomerulus, which is a tuft of blood capillaries. The glomerulus is nestled inside a cup-like sac located at the end of each nephron which is known as Bowman's capsule. Blood undergoes filtration through the pores of glomerulus.
2.Bladder. This triangle-shaped, hollow organ is located in the lower abdomen. It is held in place by ligaments that are attached to other organs and the pelvic bones. The bladder's walls relax and expand to store urine, and contract and flatten to empty urine through the urethra.
3.Quinine. Quinine is an alkaloid derived from the bark of the South American cinchona tree. It has been used as an antimalarial for over 350 years.
4.The central nervous system is made up of the brain and spinal cord. The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body.
5.The renal artery carries oxygenated blood to the kidneys.
6.Dialysis is the method of eliminating solid wastes or solutes by the process of diffusion and eliminating unwanted water by the process of ultrafiltration, from the blood. Dialysis is carried out in the kidneys in our body and thus the kidneys get rid of toxic wastes from our body by the process of dialysis.
7.The autonomic nervous system has two components, the sympathetic nervous system and the parasympathetic nervous system. The sympathetic nervous system functions like a gas pedal in a car. It triggers the fight-or-flight response, providing the body with a burst of energy so that it can respond to perceived dangers.
8.Brainstem. The brainstem consists of the medulla, the pons and the midbrain.
9.Myelin is an insulating layer, or sheath that forms around nerves, including those in the brain and spinal cord. It is made up of protein and fatty substances. This myelin sheath allows electrical impulses to transmit quickly and efficiently along the nerve cells.
10.The junction between the axon of one neuron and the dendrite of the next is called a synapse.
