Mutations can cause instant adaptations, while natural selection is the process by which adaptations occurs over a series of generations. Adaptations are changes or processes of changes by which an organism or species becomes better suited for its environment. A mutation is an alteration of the DNA sequence.
Hydrogen and oxygen which makes up h2o / water
Answer: The osmotic concentration of plasma proteins in the venous side of capillaries helps reduce the amount of interstitial fluid in tissues by inducing: <u>passive H2O diffusion along a concentration gradient</u>.
Explanation:
Osmosis is the diffusion of water through a semipermeable membrane according to the concentration gradient of water across the membrane. Osmosis is a special case of diffusion. Water, like other substances, moves from an area of higher concentration to one of lower concentration.
The answer is ‘arteries are less flexible’. This is why the older you get the more predisposed you
are to cardiovascular diseases such as high blood
pressure. However, regular
exercise may delay this development. The barometers in the blood vessels also
become less sensitive hence these vessels become less responsive to blood
pressure changes.
