17 - True, neurons are the most significant or basic unit for transferring nervous signals throughout the body. Nerves which are linked act as wires for connection. The brain wouldn't be able to send or receive signals if there were no neurons

18 - False, hormones are just chemical molecules or messengers that are sent towards tissues or organs through the bloodstream to help regulate the growth or metabolism through homeostasis process

19 - True, axons are the longest part of a neuron which helps for neurotransmission process throughout the whole nerve to the end of the motor neuron

A scientist claimed that hemophilia is caused by a functional deficiency in Factor VIII. The evidence in the passage that would

LekaFEV [45]

Answer:

C-able to relieve haemophilia

Explanation:

Factor V111 is a blood clotting factor;produced in the liver and body endothelial cells. It is usually exist as inactive form beacuse it is binded to glycoprotein (glycogen +protein) called Von Willebrand factor when released into the blood stream.

If absent in the gene of certain individuals due to mutations, it result in a sex-linked conndtion called haemophilia, where blood failed to clot when blood vessels are damaged leading to profuse bleeding/ hemorrhage.

Ideally in a normal individuals the inactive from of factor VIII are continuously circulated in inactive forms in the blood stream, until a damaged blood vessels occurs. At the injured site they are converted to active from called coagulating factor VIIIa,,by separation from Willebrand factor, react with coagulating factor IX to initiate clotting. The factor VIII is a co- factor for factor IX, and together with calcium ion,phospholipids converts t to factor IXa,

The latter converts prothrombin to thrombin. The thrombin convert fibrinogen to fibrin, which form a stable fibrin clot at the injured site to arrest bleeding. The cascade of events is lacking individual without factor VIII. Therefore bleeding occurs.

Consequently, symptoms of hemophilia can be relieved by a functional factor VIII, because it will prevent the deficiency in factor VIII in the affected individuals by acting as co-factors for the conversion of factor IX to IXa, to initiate clotting.

How ribosomes help cell maintain homeostasis

xxMikexx [17]

Answer:

Ribosomes create the thermoreceptors of the body. Another example of a homeostatic condition maintained by proteins is blood-glucose levels. When our blood-sugar levels get too high, specialized cells in the body release a protein hormone called insulin.
