When an individual muscle fiber receives a threshold stimulus, it contracts as much as possible. ... a threshold stimulus is the minimum amount of energy needed to make a muscle fiber contract.
Answer:
D) as we travel southward from the North Pole.
Explanation:
Species richness is the number of different species in a particular community. If we found 30 species in one community, and 300 species in another, the second community would have much higher species richness than the first.
Communities with the highest species richness tend to be found in areas near the equator, which have lots of solar energy (supporting high primary productivity), warm temperatures, large amounts of rainfall, and little seasonal change. Communities with the lowest species richness lie near the poles, which get less solar energy and are colder, drier, and less amenable to life. This pattern is illustrated below for mammalian species richness (species richness calculated only for mammal species, not for all species). Many other factors in addition to latitude can also affect a community's species-richness.
Answer:the condition is recessive, since the probability of appearing is 1/4.
Explanation:
Based on the information above,most of the children are dark skinned showing the dark skinned pigmentation being more dominant,thus the allele for albinism is recessive.
The hydrologic cycle is another name for the water cycle.
