<span>The cell has 1% concentration of the salt. The external environment is highly concentrated with 25% saline solution. This will lead to release of water outside the cell, by passive diffusion from a region of high conentration of solvent to lower concentration. Thus, the cell will shrink.</span>
External respiration (correct answer) involves the exchange of oxygen and carbon dioxide within the environment.
The exchange of wastes through the skin is just called excretion by sweating.
There is no exchange of nutrients that occur in the lungs but rather absorption of nutrients is the function of the gastrointestinal tract.
The exchange of oxygen and carbon dioxide within the cell is called cellular respiration and involves carrying oxygen from the blood to the cell then the cell uses it as the final electron acceptor in the electron transport chain. The metabolic wastes of the cell, primarily carbon dioxide, goes now to the bloodstream to be exchanged for oxygen in the lungs.
In terms of processing in the nervous system, the reactio<span>n was faster for the more simple tasks because it required less processing and therefore small amount of neurons had to travel through out nerve system because our frontal lobe had less delay since there was less to think about.</span>
The answer is predict future events.
I
have black hair just like my father and blue eyes like my mother. The
shape of my nose also resembles the shape of my father’s nose yet I
am taller than both of them, I have less body fat index and more
hair!
<span>I
think the environmental factors are responsible from much of the
differences between me and my parents, after all I grew up, in a
sense, in a different world. The level of pollutants in the air, the
hormones in the food, ,better medical care and even the availability
of information regarding health care choices, they are all factors
that change from generation to generation and change they way we are
and a very real way. It is true that we are the product of our genes
but the environment plays a determinant role in our development as
well.</span>
