Answer:
Centre of Gravity
The centre of gravity (COG) of the human body is a hypothetical point around which the force of gravity appears to act. It is point at which the combined mass of the body appears to be concentrated[1]. Because it is a hypothetical point, the COG need not lie within the physical bounds of an object or person. One subjective way (there are objective measures) to approximate the COG of an object is to visualise it balancing on one finger.
Centre of Gravity in the Human Body
In the anatomical position, the COG lies approximately anterior to the second sacral vertebra. However, since human beings do not remain fixed in the anatomical position, the precise location of the COG changes constantly with every new position of the body and limbs. The bodily proportions of the individual will also affect the location of the COG.
The spinal cord is the primary means for transmitting messages between the brain and the rest of the body.
Answer:
They play an important role in educating nonscientists about the content and processes of science. In fulfilling these responsibilities scientists must take the time to relate scientific knowledge to society in such a way that members of the public can make an informed decision about the relevance of research.
Explanation:
theres the answer
Incomplete question. Here are the missing parts.
What will happen to the substances in this diagram to bring the concentrations closer to equilibrium?
A. The solute will flow into the cell from the surrounding environment.
B. Nothing will change--it is already in equilibrium.
C. Water will flow into the cell from the surrounding environment.
D. Water will flow out of the cell and into the surrounding environment.
My answer:
D. Water will flow out of the cell and into the surrounding environment.
The solute cannot pass through and go inside the cell, water has to flow from the cell to the surrounding environment to bring the concentration closer to equilibrium.
