The natural blind spot is due to lack of receptors where the optic nerve and blood vessels leave the eye. There can also be artificial blind spots when something blocks light from reaching the photoreceptors, or when there is local adaptation of the retina as just after seeing a bright light
<span>Blockage of the Cerebral Artery can reduce blood supply to the brain, causing a stroke (Ishcemic Stroke)
Blood is carried to the brain by two pair of arteries, i) The Internal Carotid arteries, ii) The Vertebral arteries.
Stroke is a neurovascular condition affecting blood vessels in the brain. There are two types of Stroke i) Ischemic Stroke ii) Hemorrhagic Stroke.
In Ischemic stroke occlusion of a cerebral artery causes the damage to brain tissue dependent on blood supply from the affected vessel</span>
Answer:
Ribosomes, endoplasmic reticulum, Golgi apparatus, vesicles.
Explanation:
The endomembrane system in eukaryotes has divided the cell organelles into the structural and functional unit. This system plays an important role in the protein processing, its sorting and transport of protein.
The protein is prepared from the plasma cells. The antibodies is made on the ribosomes by the translation process. From the ribosomes, it will move to the endoplasmic reticulum for the glycosylation and protein folding. Then it moves to the golgi for the further protein packaging and processing. With the help of the vesicles it moves to its destination part in the cell.
Thus, the correct answer is option (d).
Answer:
the answer is C) They increase the rate of the chemical reactions involved in digestion
Explanation:
The digestive functions of saliva include moistening food, and helping to create a food bolus, so it can be swallowed easily. Saliva contains the enzyme amylase that breaks some starches down into maltose and dextrin. Thus, digestion of food occurs within the mouth, even before food reaches the stomach.
