Answer:
The correct answer will be- 95X.
Explanation:
Magnification of a microscope is the amount of the visual enlargement of the observed object.
The magnification of a microscope can be increased by changing the lens closer to the object called an objective lens while the ocular lens close to the eyes remain fixed. The magnification is a result of the multiplication of the power of the ocular lens to the objective lens like in the given case:
Magnification= power of ocular lens X power of the objective lens.
950 X = 10X x P(o)
P (o)= 95X
Thus, 95X is the correct answer.
Vacuole perform digestion in amoeba while stomach perform digestion in mouse.
Explanation:
Amoeba is a unicellular organism so they lack stomach. The food which is taken are digested in the vacuole of the amoeba with the help of specific enzymes and absorbed by the cytoplasm in order to use for performing different activities, while mouse is a multicellular organism and have the stomach which perform the function of digestion. The digestive system of mouse is similar to humans.
Novocaine is a logal anesthetic agent which is commonly used during dental procedures or other oral processes. This causes numbness of the infected area so that the patients will not feel the pain. This is a local name for procaine which was discovered by the German chemist named Alfred Einhorn in 1905.
The duration to which we expect the numbness varies to the different factors. The factors include the location of the application, the area, concentration, and presence of other anesthetic chemical. It is expected at least that novocaine will last for 1.5 to 3 hours.
Answer: True
Explanation:
The cerebrum and the cerebellum are parts of brain:
Cerebellum: lies under the cerebrum. Its purpose is to coordinate movements of the muscles, to maintain posture and balance.
Cerebrum: is the main portion of the brain, which consists of hemispheres right and left. It performs higher functions such as reading vision, touch, hearing, reasoning, emotions, and thinking.
They both contain a gray mater in their surface cortex and deeper nuclie whose function is related to motor control, coordination , precision, and balance.
Hence, the statement is true.
the pathway coming to the lungs are veins and the ones going away from the lungs are the arteries :)
