Question
Chapter 21.1, Problem 3CC
Summary Introduction
To determine:
The effect of only asexual reproduction of organisms in a population that have stopped the sexual reproduction by referring the concept 10.4.
Introduction:
Asexual reproduction involve production offspring from a single organism, that inherit the genes from one parent only whereas the sexual reproduction involve production of offspring from two individuals of different sexes (male and female), results in recombination of their genetic information in offspring.

4)either of them need to be virgins
Identify each of these statements as ones that describe asexual reproduction (A),sexual reproduction (S), or could describe both (B) forms of reproduction. Writeyour answer on the space provided before each number.B= BothA= Asexual ReproductionS= Sexual Reproduction1. organism does not need a mate to reproduce2. takes some time to create offspring-3. the offspring are not the exact copy of their parent/s4. it is a quick process5. does not need to develop special cells for reproduction6. environmental changes affect all individuals-7. may only be able to reproduce with a limited number or may notreproduce at all_8. offspring are reproduced9. characteristics are passed down to the next generation10. many new organisms are created in a short period of time11. dogs and cats reproduce this way12. amoeba, yeast and bacteria reproduce this way.13. plants reproduce this way14. production of gametes is necessary15. its purpose is the survival and continuity of species

- A salamander can regenerate the entire front part of the brain; including sensory structures. Being a salamander enthusiast you use laser capture microdissection to isolate a proliferative group of cells after sectioning off part of the brain of your pet salamander. What are 5 ways that you could determine if these cells are indeed NEURAL stem cells and briefly describe each?arrow_forwardSome organisms are capable of asexual or sexual reproduction. Under favorable conditions, reproduction proceeds asexually. When conditions become more stressful reproduction switches to a sexual mode. Why? Question options: Sexual reproduction is simple and more rapid allowing larger numbers of offspring to be produced. Sexual reproduction requires two separate individuals, who can mutually provide nutrient support during stress. Sexual reproduction produces individuals with new combinations of recombined chromosomes increasing diversity. Asexual reproduction requires more energy.arrow_forward8)Let's say that the an experiment is planned to test the following hypothesis: Sea urchin fertilization will go down as temperature rises What will be the independent & dependent variables in this experiment? Dependent variable---(a Number of urchins used)(b Concentration of carbon dioxide)(c Fetilization rate)(d Proportion of male & female urchins used)(e Species of urchins used)(f Water temp)(g Air temp) Independent variable---(a Number of urchins used)(b Concentration of carbon dioxide)(c Fetilization rate)(d Proportion of male & female urchins used)(e Species of urchins used)(f Water temp)(g Air temp)arrow_forward
- Sexual reproduction involves an organism (A.) growing from body parts that are cut or broken off the parent. (B.) being produced through a unique combination of DNA from two gametes. (C.) generating an identical offspring on the surface of its own body. (D.) replicating its DNA before dividing in half to produce two organisms.arrow_forwardDo all organisms reproduce sexually.

Why is sexual reproduction so common in multicellular organisms? 1 - because it produce more offspring 2 - because it creates genetic variation in the population 3 - because a sexual population can grow faster than an.

- evel Basic Features of Reproduction Which of the following features does not differentiate asexual reproduction from sexual reproduction? Asexual reproduction involves a single parent but it is not the case in sexual reproduction. Sexual reproduction does not involve gamete formation but asexual reproduction does. Asexual reproduction does not involve mitosis while sexual reproduction does. I. II. III.

The queen is the only reproductive individual—the workers aresterile. a) According to Hamiton’s rule, what is the maximum ratio of cost to benefit (C/B) for theworkers in order for this system to evolve?b) Some colonies of ants have multiple queens, which can be related to different degrees.Imagine that two sisters start a colony, so that they are the mother or aunt to allworkers.
