Explanation:
For the evolution of life to begin, the Earth formed as Earth is the only planet which can support life and has favourable conditions. Life first began from prokaryotic organisms which engulfed smaller prokaryotes and gave rise to unicellular eukaryotes. With the passage of time, the unicellular eukaryotes evolved to form multicellular eukaryotes. The life on Earth then started after the formation of multicellular eukaryotes in the oceans and seas.
Answer:A radical (often, but unnecessarily called a free radical) is an atom or group of atoms that have one or more unpaired electrons. ... A prominent feature of radicals is that they have extremely high chemical reactivity, which explains not only their normal biological activities, but how they inflict damage on cells.

Answer:
The correct option is A. The oxygen atoms diffuse through the atmosphere and are inhaled by animals.
Explanation:
Photosynthesis can be described as a process in which plants use the light from sun to convert carbon dioxide and water into glucose. Oxygen is made as a by-product of this reaction. This oxygen is released into the atmosphere by the plants through the mechanism of diffusion.
The oxygen released into the atmosphere is taken up by animals. Animals utilize this oxygen for the process of respiration.
The process of respiration and photosynthesis are opposite to each other.
I believe that secretion into the tubular fluid occurs when the principle cells in the Proximal convoluted tubule secrete H+ into the urine.
Tubular secretion is the transfer of materials from peritubular capillaries to the renal tubular lumen; it is the opposite process of reabsorption. This secretion is caused mainly by active transport and passive diffusion.
