Answer:
Averaging the fitness of its members.
Explanation:
The fitness of a whole population can also be determined by averaging the fitness of its members. Absolute fitness is the ratio between the number of individuals with a genotype before selection versus after selection. Fitness is usually discussed in terms of genotypes, or collection of genes.
Answer;
Both genes and the environment
Both genes and the environment direct and produce human behaviors, personality traits, and even psychological disorders.
Explanation;
-Human behavior is determined by complex interactions of both nature and nurture. Genetic make up of a person together with the environment influences the physical and behavioral characteristics of an individual.
-Personality is a complex trait that is influenced by many different genetic and environmental factors. Personality traits are also polygenic trait because multiple genes are involved in determining these traits. Because a large number of genes each playing a small role in determining our personality, it is difficult to isolate and identify these genes.
Answer:
Oceanic crust is denser than continental crust.
Explanation:
The density difference arises because of <em>partial melting</em>.
When you partially melt a rock, the lighter minerals melt before the denser ones, so the rocks that form from the melt are less dense than before.
After each cycle of partial melting, the rocks become progressively less dense.
The continental crust is formed more cycles of partial melting than oceanic crusts. As a result, the density of continental crust (2.7 g/cm³) is less than that of oceanic crust (3.3 g/cm³).
Consequently, the denser oceanic crust is subducted below the continental crust at a convergent boundary.
I'm pretty sure the answer is oxygen because photosynthesis is the reason we have oxygen
