Oxygen is an element in the sixth group of the periodic table. This means it contains 6 electrons in its valence shell. Therefore, to complete its octet, it will prefer to gain two electrons rather than to donate 6. This is why its valency is -2. The relatively easy to achieve octet makes Oxygen a reactive element.
Because it was to cold for them to plant and raise crops
In the Claritin commercial, the man is laying in the grass with a
beagle puppy. The beagle is a breed of small hound that is similar to a larger
foxhound that has approximately
220 million scent receptors. This is the reason why they are employed as
detection dog and not as guard dogs for they are usually friendly dogs.

producers: photosynthetic plants
consumers: humans or any life that breathes oxygen
How are each of the spheres connected to the carbon cycle?
biosphere: regions occupied by living organisms need the carbon cycle to survive.
geosphere: is the habitat of the biosphere, w/o the geosphere plants would not be able to perform carbon fixation.
atmosphere: carbon cycle can contribute to global warming.
anthrosphere: involves the external environment and plants, so the carbon cycle is present.
hydrosphere: carbon cycle still happens in submerged plants as sunlight can pass through water.
How is the growing human population going to affect the carbon cycle?
more humans means more carbon being produced. more co2, more cars, more pollution being expelled into the air. Some things that can occur with the carbon cycle include an excess of co2 being present in the air as there isn't enough plants to efficiently remove it from the air, which can lead to co2 buildup in the atmosphere resulting in climate change.

Answer:
backcrossing
Explanation:
when you cross the offspring (inttermediate size) to one of the parental strains, (the small strain for example) you should get 1/2 intermediate size and 1/2 parental size (small) if body size is due to single gene. On the other hand if the trait "size" is polygenic you should get mice around half way between small and intermediate sizes.
