hi! producers are the main source of energy for consumers because they turn sunlight into chemical energy. without producers, no ecosystem would be able to survive because consumers would no longer have energy needed to live. hope this helps!
Appositional growth is the term for the rise in diameter. The periosteum's osteoblasts build compact bone around the exterior bone surface.
Therefore they are consider matter. Remember anything with a mass is matter.
Well, experimentation can be really expensive, so when funding is provided it gets rid of a lot of obstacles.
That's intimidating, lol!
Okay so choice A says that #8 is heterozygous for the trait which means for example it would have the genotype Aa. She's a female witht he dominant trait. This is a possibility.
Choice B says #10 is heterozygous, but if it has the recessive trait it would have to have the geotype aa which is homozygous so this one is wrong.
Choice C says #13 is homozygous dominant which means the genotype will be AA. The individual can still have the dominant trait without having the AA genotype (it can also be Aa) so this one is wrong.
Choice D says that #3 is homozygous dominant but like with choice C, the chart doesn't specify the genotypes of each so it'd be a guess to say that #3 is homozygous. This is wrong.
This means that choice A is true!
