Cell Biology Reproduction: Asexual to sexual by Devin Reese, PhD. Reading Quiz Teach with this You're going to work in a lab studying a species of bacteria, and want to seem knowledgeable. Which can you safely assume about its reproduction? The bacteria does not reproduce because it has other ways of spreading around. The bacteria reproduces asexually through the process of binary fission. The bacteria reproduces sexually by sharing gametes with other bacteria. The bacteria reproduces both asexually and sexually, depending on conditions. Both asexual and sexual reproduction yield clones of the parents. true false What is the BEST evidence that asexual reproduction was the earliest mode on Earth? In prokaryotes, sexual reproduction is the most common mode today. In prokaryotes, asexual reproduction is the most common mode today. In eukaryotes, sexual reproduction is the most common mode today. In eukaryotes, asexual reproduction is the most common mode today. What percent of these animals are able to reproduce sexually? CC BY 3.0 mossi889 20 percent (two of the ten) 50 percent (five of the ten) 70 percent (seven of the ten) 100 percent (ten of the ten) These depictions are representing an aspect of asexual reproduction. Public Domain true false In which scenario would you expect to see the most rapid growth of a population? Asexual reproduction in a stable environment Asexual reproduction in an unstable environment Sexual reproduction in a setting with ample mating opportunities Sexual reproduction in a setting with scarce mating opportunities Why might sexual reproduction have persisted in evolutionary terms? It requires less energy and time than asexual reproductions It requires more time and energy than asexual reproduction. It yields lower diversity of offspring than asexual reproduction. It yields higher diversity of offspring than asexual reproduction. Organisms capable of both modes of reproduction tend to reproduce sexually if resources are becoming scarce. true false What does this photo of grove snails (Cepaea nemoralis) BEST demonstrate about sexual reproduction? CC BY-SA 4.0 Angus Davison Sexual reproduction is used by invertebrates Sexual reproduction creates lots of offspring. Sexual reproduction produces genetic variability. Sexual reproduciton yields many look-alike offspring. In this photo of an aphid giving birth to a live offspring, is it practicing sexual or asexual reproduction? CC BY-SA 3.0 MedievalRich Sexual because the offspring closely resembles the parent, as would a clone. Sexual because in asexual reproduction, its eggs are laid outside of its body before they hatch. Asexual because the offspring closely resembles the parent, as would a clone. Asexual because in sexual reproduction, its eggs are laid outside of its body before they hatch. Which is the BEST description of asexual reproduction using the horserace metaphor? Asexual reproduction is like betting on a known horse that has a high chance of winning, unless conditions change. Asexual reproduction is like gambling on an unknown horse that looks extraordinary during the warmup laps. Asexual reproduction is like betting on a set of horses with entirely unknown performance capabilities. Asexual reproduction is like gambling on a set of horses with varied chances of winning depending on conditions. In a casino metaphor, sexual reproduction would be like splitting your bets amongst a variety of poker hands. true false Score Quiz
