Answer:
Carbon's characteristics include its ability to bond with oxygen, hydrogen, nitrogen, phosphorus and sulfur.
Explanation:
Carbon biochemical compounds are essential to all life on the planet. Because of its bonding ability, carbon can form single, double, or triple covalent bonds with other atoms.
Answer: Arctic foxes have several adaptations that allow them to survive. Their round, compact bodies minimize surface area that is exposed to the cold air. Their muzzle, ears, and legs are short, which also conserves heat.
Explanation:
Answer:
ExplanatThe geometric or exponential growth of all populations is eventually curtailed by food availability, competition for other resources, predation, disease, or some other ecological factor. If growth is limited by resources such as food, the exponential growth of the population begins to slow as competition for those resources increases. The growth of the population eventually slows nearly to zero as the population reaches the carrying capacity (K) for the environment. The result is an S-shaped curve of population growth known as the logistic curve. It is determined by the equation As stated above, populations rarely grow smoothly up to the …(100 of 4579 words)

Answer:
This is because fluids have a polar nature, so they couldn´t cross the lipidic bilayer that constitutes the plasma membrane
Explanation:
Plasma membranes are contituted by lipid bilayers. These kind of compounds are hidrophobic (they reject water) and don´t permit the freely passage of hidriphilic molecules that can disolve in water, constituing fluids. Because of that cells developed transport mechanism like endocytosis.
Answer:
Explanation:
some gases prevent the escape of heat from the earth.There will be an increase in the percentage of such gases would cause the average temperatures to increase world wide.This is known as greenhouse effect.Carbon dioxide is one of the green house gases.An increase in the carbon dioxide content in the atmosphere woul cause more heat to be retained by the atmosphere and lead to global warming.
