Explanation: Survivorship curves fit three types. A Type I curve shows a low death rate in early and middle life but the death rate increases steeply in old age. A Type II curve shows a death rate is more constant throughout the lifetime of the species.
Answer: Since the industrial revolution, human activities have also resulted in an increase in natural greenhouse gases, especially carbon dioxide. An increase in these gases in the atmosphere enhances the atmosphere's ability to trap heat, which leads to an increase in the average surface temperature of the Earth.
Explanation:
Two parent mice with black fur have offspring with white hair.
Since both are heterozygous, that means they both have a dominant and recessive allele, but since they have a dominant, that trait is displayed. Since both also have a recessive allele, there is a possibility that they can have offspring with a recessive trait.
In other words, if you have 2 heterozygous parents that show a dominant allele, offspring that display the recessive allele is possible.
Hope this helps :)
