The study of your brain and mental illnesses and understanding how the brain functions.
Answer:
Does not take up the stain.
Explanation:
Negative staining refers to the process wherein the unstained specimen is visualized under the darkly stained background.
One of the examples is capsule staining wherein the capsulated cells are stained with India ink or nigrosin dyes. The particles of these dyes stain the background blue-black but cannot enter the capsule.
Hence, the light-colored capsulated cells are visualized in the midst of the blue-black background.
Answer:
c. Cr. N. IV = trochlear nerve
Explanation:
The IV cranial nerve is the trochlear nerve. It is located on the dorsal side of the brain near the back. It is a motor nerve and the smallest nerve which serves eye. This nerve present in the superior oblique muscle of the eye. The superior oblique muscle controls the rotational movement of the eyeball and prevent the eyeball from rolling upward into the eye socket.
Answer:
E) can usually make enough ATP for skeletal muscle function
Explanation:
Glycolysis is the main process by which cells obtain energy. During glycolysis, glucose is fully oxidized to obtain ATP, this is the 'fuel' for cellular function. Glycolysis is oxygen dependant, meaning that in order to successfully complete the process, enough oxygen must be available.
There are a few exceptions in which glycolysis is unable to provide enough ATP, an example is strenuous exercise. In this case the speed of oxygen consumption is very high, therefore at some point the oxygen intake is not enough. There are several mechanisms that regulate the production of ATP. In case of strenuous exercise, different process are activated to supply the cell with the necessary energy to keep on functioning.
Among the latter mentioned processes, there is anaerobic production of the oxidation of lactate, that does not require oxygen. Other example is the usage of creatine phosphate to obtain energy. Therefore, muscular cells have many ways of obtaining energy, but this secondary mechanisms are only activated in specific situations.
The Earth turns on its axis every day; it orbits the sun, just like all the other planets in our Solar System. You can cross out D and A, obviously. Which leaves us with answers B and C. Now, C says that the Earth turns clockwise, which is false; when viewed from space, they determined it turned counter-clockwise, which leaves us with B. Hope this helped
