Answer:
true
Explanation:
Cerebrospinal fluids is a colorless fluid that is secreted in the choroid plexus,and circulates in the ventricles system and sub -aranchinoid space of the brain and spinal cord. its provides nutrients to the surrounding neurons, cushions the effects of trauma, pressure, acts as buffer and provides protection through immune system .
it plays a vital role in regulating blood flow, through a process called cerebral auto regulation,This is needed to maintain efficient cerebral blood flow of oxygen and other metabolites, and withdraw of metabolic wastes from the brain.
in order to analyze it to diagnose some neurological diseases its sample is usually taken out in a process called lumbar puncture.

Answer:
A. Pathogen- 4
B. aerobic- 7
C. hypothesis- 6
D. herbivores- 2
E. one another differentiation -5
F. homeostasis- 1
G. metabolism- 3
Explanation:
A. Pathogen- a pathogen is a living organism which can feed on other organism and can utilise their cellular components for their own survival. This affects the host cell and they get infected and the pathogen thus causes disease.
B. Aerobic- The oxygen appeared on Earth later compared to the time life originated on earth. Therefore some organism living today can use oxygen for survival and some not. The organism which utilises oxygen for their survival is known as aerobic microorganisms.
C. Hypothesis- The hypothesis is a predicted statement formulated based on the study related to the natural event which can explain the natural event.
D. Herbivores- The organism which cannot make food for themselves on their own but rely on another organism, especially the plants, are known as the herbivores.
E. Differentiation- Differentiation is the process which forms a variety of cells from a single cell and can perform different functions.
F. Homeostasis- is the mechanism which can maintain the internal conditions of the organisms.
G. Metabolism- refers to the chemical reactions which can help perform the normal functioning of the organism.

Proteins are synthesized in the ribosomes. Newly synthesized proteins that are meant for the nucleus usually possess a localization sequences which direct it to a protein on the nuclear membrane through which it will enter into the nucleus.<span />
