Some 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.

Which of the following is an advantage of asexual reproduction over sexual reproduction? It requires a partner. It does not require a partner. The resulting offspring have no genetic diversity. It leads to offspring with high genetic diversity.
Which of the following is a disadvantage of sexual reproduction? a.)Offspring can be reproduced more quickly than by sexual means b.)Two parents are required for making sex cells c.)Offspring are genetically different d.)Genetic diversity makes organism respond uniformly to environment changes
Unicellular organisms such as bacteria depend on asexual reproduction. 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. Asexual population 4 - because it produces offspring that are identical to the parents 5 - because it requires less energy
In asexual reproduction only ______ ______________is involved, and the offspring are genetically _____________________to the parent. – In Unchanging environments In sexual reproduction _______ _________________are involved, and the offspring are genetically ___________________from the parent. – Changing environments Evolution is _____________ _____________over time in a ________________________. Different organisms have different genes. How is it that so many organisms seem perfectly suited to their environment? ___________ _____ ___________________. After a genetic __________or mutation in an organism, It survives, reproduces, and passes along its genes. Beneficial ______________ develop at random. The environment “___________” beneficial adaptations. Adaptations are an inherited characteristic.
Sexual reproduction is the best method of procreation because it guarantees survival of species and genetic diversity. There are no disadvantages of sexual reproduction.
Identify whether the following statements describe Asexual or Sexual Reproduction. Answer it all. 1. Requires only one parent and creates offspring genetically identical to parent 2. Needs two parents and creates offspring genetically unique from parents 3. Leads to more genetic diversity 4. Has a little chance of genetic variation 5. Commonly happens to more complex organisms such as plants and animals 6. Commonly occurs to less developed organisms such as bacteria and fungi 7. Does not require finding a mate and formation of gametes 8. Requires finding a mate and formation of gametes 9. Typically happens in faster time period 10. Usually occurs in slower time period
Which of the following organism that undergoes asexual reproduction is the most interested to be studied? •Hydra •Some species of sea stars •Cyanobacteria •Some plants •Ferns
Compare between asexual and sexual reproduction Asexual Sexual Disadvantage Advantage Life Cycle
Which of the following statements best describes the advantage of sexual reproduction in organisms? It reduces genetic variation, which may be useful in the future. It prevents adaptation in a changing environment. It yields offspring with novel combinations of traits. It eliminates the possibility of harmful traits being passed on. tnf: Which of the following statements best describes the functions of villi and microvilli? Villi and microvilli form the inner layer of epithelial tissue in the small intestine and increase the absorption of nutrients from chyme. Villi and microvilli absorb food through the small intestine via smooth muscle contractions called peristalsis. Villi and microvilli increase the surface area of the small intestine, which increases the absorption of nutrients by diffusion. Villi and microvilli increase the surface area of the small intestine, which aids in the absorption of bile salts and vitamin B12.
Most eukaryotic organisms use sexual reproduction as their primary means of perpetuating their species. Gametes are formed via meiosis. However, some species primarily reproduce via asexual means. Reproduction is accomplished via mitosis. Aspen trees most commonly reproduce by such asexual methods of cloning.What are the advantages and disadvantages of reproduction by asexual means? Why do some species reproduce in this manner? Why don't all species?
List three reasons why individuals that result from sexual reproduction do not have the same DNA instructions as their parents.
An egg and similar share: the same size the same degree of mobility the same number produced each month the same number of chromosomes
