Summary Introduction

To determine: The costs of energy associated with sexual reproduction.

Introduction: The phenomenon, called reproduction, is important for the continuous survival of species. The two different modes of reproduction are sexual reproduction and asexual reproduction. The asexual reproduction involves the production of offspring with genes inherited from a single parent. On the contrary, sexual reproduction involves the fusion of two haploid gametes to form a diploid zygote. One of the two gametes comes from the male and the other gamete comes from the female.

Summary Introduction

To discuss:  The importance of sexual reproduction that outweighs those costs and accounts for the observation that most animals reproduce sexually.

Introduction: Reproduction is an important phenomenon for ensuring the survival of species. The two different modes of reproduction are sexual reproduction and asexual reproduction. Asexual reproduction involves the production of offsprings with genes inherited from a single parent. Sexual reproduction involves the fusion of two haploid gametes to form a diploid zygote.

Multiple choice:which of the following are disadvantages of sexual reproduction? Requires more timeRequires more energy to be expended during courtship Favorable gene combo are broken up Allows for the removal of bad genetic combinations
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.
For each of the following, choose whether it is true of sexual reproduction or asexual reproduction. Each female produces more daughters. Each female produces more genetically variable offspring. Most common eukaryotic reproductive strategy. advantageous when the environment is stable [Choose ] [Choose ] [Choose ] [Choose ]
