Answer:
diffusion, higher , and Lower.
Explanation:
Within systemic capillaries, substances such as oxygen, hormones, and nutrients move by diffusion from their relatively higher concentration in the blood into the interstitial fluid and then into the tissue cells, where the concentration of these materials is lower.
We now that diffusion is process of movement of solute molecules from a region of higher concentration to region of lower concentration. That is against the concentration gradient.
<span>The pressure exerted by a static fluid depends only upon the depth of the fluid, the density of the fluid, and the acceleration of gravity. It can be calculated as follows:
P = density x g x h
P = 1000 kg/m^3 x 9.8 m / s x 33 ft x 0.3048 m/ft
P = 98572.32 kg/m^2
Hope this answers the question. Have a nice day.</span>
Hydrogen is the only atom that does not have neutron electrons in the first energy level/shell.
Answer:
B
Explanation:
I mean just think about it where else are the particles going to move? The room right?
Answer:
the correct option is:
We only need one electron to achieve a noble gas configuration
Explanation:
Halogens have 7 valence electrons in their outer energy shell, so when reacting with another element they satisfy the octet rule.
Halogens show trends in their binding energy from top to bottom on the periodic table with fluoride showing minimal deviation. They are shown to have strong bonding energy with other atoms but weak interactions with the F2 diatomic molecule. This means that as you go down the periodic table the reactivity of the element decreases due to the increase in the size of the atom.
Halogens are highly reactive, so they can be harmful to biological organisms in sufficient quantities. Its high reactivity is due to the high electronegativity that its atoms present due to its highly effective nuclear charges.
