Thymine has a methyl group and is better suited for the storage property of the DNA molecule as it is far more stable compared to Uracil.
RNA contain Uracil instead of thymine so as to make differentiation of RNA molecule from DNA molecules easier.
Mono hybrid cross dihybrid cross homozygous cross heterozygous
Answer:
Over time the beetle population will adapt as a result of natural selection because the beetles "desired" by the birds will be eaten and their population will dimish as a result. The beetles that are not eaten by the birds will have a chance to allow their population to grow because a. they aren't being eaten and b. they have more space as the other colored beetle's population is shrinking. Causing the eaten species to become less prominant and the not eaten beetle's population to grow and take over in place of the other beetles.
Answer:
invasive species are a problem both in anthropogenically altered and natural environments
Explanation:
An invasive species can be defined as a non-native species introduced into a new environment which then becomes abundant. Only in the US, it is believed that there are approximately 4,000 invasive species (some examples include the feral pigs, grey squirrels, European rabbits, etc.). In general, invasive species have a negative impact on the ecosystem, especially by displacing native species and thereby altering the trophic chain. In anthropogenically altered environments (anthromes), human beings are considered to be an invasive species.
