Addie Logan from Sydney, Australia has been observing a population of rhinoceros beetles in her backyard for over a decade. She has noticed that males use their oddly shaped exoskeleton "horns" on their head to joust with other males to gain access to breeding sites where the single females hang out. Addie noticed that the males horns came in 3 lengths, long (LL), medium (LS) and short (SS). She also noticed that over time, the average length of all the...

LLL LULUI AL SOLULIUI 1. What are the four criteria (refer to your lecture notes) that must be met in order for natural selection to result in the evolution of a phenotypic trait? Also, explain why a trait evolves in a population as a result of these 4 criteria being met (in other words, provide a clear and detailed explanation of why the Irequency of a phenotypic trait would increase across generations as a result of these 4 criteria being...

Which example illustrates the difference between Lamarck's vs. Darwin's theories of how new species come from existing species. A. Lamarck may have stated that with the rapid distance between pieces of ice in the arctic, polar bears would naturally be able to swim further than their parents would have, whereas Darwin would have said that the polar bears who could swim far enough would survive, those who could not would die. B. Lamarck may have stated that with the need...
Climate change is a threat to the existence of many species.
QUESTION 2 Climate change is a threat to the existence of many species. Which of the following limits to natural selection hinders the adaptation of species to the new climate conditions? The developmental plans of plants and animals are too complex. They cannot cope with the warmer temperatures. Mutations happen so frequently that beneficial alleles change before natural selection can substantially increase their frequency Many species not have gene variants in their gene pool that are beneficial in higher temperatures. Climate change happens so...

1. Population is not used in describing species. Population is a group of organisms of the same species populating a given area, a group of individuals of the same species that live in the same area and interbreed, producing fertile offspring. Interbreeding, sexual reproduction, natural selection and color are used in describing species. Individuals in an interbreeding population share in a common gene pool. My question is can you tell me how interbreeding, sexual reproduction, natural selection and color are...
Female stalk-eyed flies prefer to mate with males that have longer eye stalks
1Female stalk-eyed flies prefer to mate with males that have longer eye stalks, and the average male eye stalk length is much longer than that of females. This is an example of _______ mutation macroevolution. disruptive selection sexual selection. 2 Several different species of small nocturnal primates called, bush babies live in the woodlands of Africa While several different species of bush babies often live in the same habitat they cannot interbreed because bush babies have genitalia that will only fit the genitalia of females belonging...

The genetic code is "redundant" because: Question 1 options: Each amino acid is specified by only a single codon Most amino acids are specified by multiple codons Codons are groups of four consecutive DNA bases Each codon can specify multiple amino acids Question 2 (1 point) A mutation in the DNA may not result in change in protein function because: Question 2 options: Many different amino acids share similar chemical properties, so can substitute for one another without altering function...
