Stick bugs are perhaps one of the better known examples of insect mimicry. Their twig-like appearance helps to defend them against predators that hunt by sight.
Answer:
a gas produced during photosynthesis
Explanation:
during photosynthesis plants use carbon dioxide, water and sunlight to make sugar (glucose) and a waste product, oxygen gas.
the equation of this process can be:
6 CO2 + 6 H2O + light energy → C6H12O6 + 6 O2.
carbon dioxide + water + light → glucose + oxygen
Genetic drift is the variation of population allele frequency, natural selection changes allele frequency by favoring those alleles that give an organism a reproductive fitness advantage
Polycythemia is defined an abnormal increase in the number of circulating red blood cells. It is mainly caused by a cancerous condition known as myeloproliferative disorder or due to a low supply of oxygen to body tissues usually due to living in high altitude areas and the body tries to compensate by producing more red blood cells to increase oxygen carrying capacity of the blood
Normal blood count values in a male adult is 4.7 to 6.1 million cells/mcL, while in a female adult it is 4.2 to 5.4 million cell/mcL.
If this blood cell count is significantly higher then these values, and remains there or continues to rise, over a given period of time, accompanied with some specific symptoms, then polycythemia is suspected.
