The picture below shows a peacock. Many of the early peacocks did not look like they do today. Their feathers were typically not as bright nor as
large. Which of the following best explains the differences between early and modern peacocks?
Larger, brighter feathers mad the peacocks carry more weight, so these peacocks became stronger and were healthier as a result
Larger, brighter feathers were more attractive to mates, and therefore peacocks with smaller, duller feathers did not survive over
Larger, brighter feathers helped the peacocks to assorb more sunlight, keeping them warm during winter months
Od Larger, brighter feathers made peacocks more noticeable to predators, so these peacocks became stronger from defending
themselves more often

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.

just finished the test, the answer is d, greg is the least cost-effective because he charges the most for the project

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.
