The oxidation of organic compounds by molecular oxygen to produce CO2 and water releases free energy because electrons are being moved from atoms that have a lower affinity for electrons.
Answer:
Multicellular organism is the example of complexity of the natural world.
Explanation:
Multicellular organism such as human which is made of billions of cell. Each cell perform a specific function. The function of one organ is different from the other organ. For example, brain of human is made of millions of neurons which takes instructions from brain to the organs and bring messages from organs to the nervous system in the form of electrical impulses. In short every system in our body is full of complexity.
Answer:
Rods and cones
Explanation:
The retina contains the light sensitive cells, the cones and rods. It is here that an image is formed. Rods contain the photochemical pigment rhodopsin for dim light vision. Cones contain the photochemical pigment iodopsin for bright light and colour vision.
The answer is letter c. produces protein.
<span>Water, ions and molecules requires for cellular processes, can leave and
enter cells through a passive process like diffusion. Diffusion is random
movement of molecules yet has a net direction to regions of lower concentration
in order to reach a balance. Simple passive diffusion takes place when small
molecules pass through the lipid bi-layer of
a cell membrane. Depending on carrier proteins, facilitated diffusion is
imbedded to allow certain substances to pass through, which may not be able to
diffuse through cell membrane.</span>
