Answer:
The Grants's research shows that variation within species increases the likelihood of the species' adapting to and surviving the environmental change.
Explanation:
The beaks of individual birds can change depending on what food is available.
Over time, individuals can evolve to better fit the environment by changing heritable traits.
Beak depth and length must affect survival and/or reproduction of birds.
Beak depth and length must be heritable.
Beak depth and length must show variation among individuals of a single species.
Genetic diversity serves as a way for populations to adapt to changing environments. With more variation, it is more likely that some individuals in a population will possess variations of alleles that are suited for the environment. Those individuals are more likely to survive to produce offspring bearing that allele.
Small tt because there are large TT on the top
It is what makes plant stems, leaves, and branches so strong.
