Short Answer

Expert verified
c. Hermaphroditism

Step by step solution

01

Understanding the Problem

Determine which form of reproduction could be best suited for a sexually reproducing animal with limited mobility. Consider the mobility and reproductive characteristics needed for each option.
02

Definitions of Reproductive Types

Review the definitions for each reproductive method: a. Fragmentation: A form of asexual reproduction where an organism breaks into parts that each grow into a new organism. b. Budding: A form of asexual reproduction where a new organism grows from the body of the parent organism. c. Hermaphroditism: A condition in which an individual has both male and female reproductive organs. d. Parthenogenesis: A form of asexual reproduction where an egg develops into a new individual without fertilization.
03

Evaluating Limited Mobility

Assess which method of reproduction might be advantageous to an animal with limited mobility. Limited mobility can impact the ability to find mates, thus self-fertilizing capabilities can be beneficial.
04

Matching the Best Reproduction Method

Identify which reproductive method allows for sexual reproduction and is compatible with limited mobility. Hermaphroditism allows an animal to reproduce sexually without needing a partner.
05

Conclusion

Based on the evaluations above, hermaphroditism (c) is the most suitable reproduction method for a sexually reproducing animal with limited mobility.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

hermaphroditism
Hermaphroditism is a fascinating and efficient reproductive strategy found in many animals, particularly those with limited mobility. In hermaphroditism, an individual possesses both male and female reproductive organs. This unique feature allows these animals to enhance their chances of successful reproduction.

Since finding a mate can be challenging, especially for slow-moving or stationary animals, being able to self-fertilize or mate with any encountered individual is extremely advantageous. Many hermaphroditic animals can either self-fertilize or cross-fertilize with another hermaphrodite.

Examples of animals that exhibit hermaphroditism include many snail species, earthworms, and some fish. These animals benefit from the increased flexibility in their reproductive options, ensuring they can continue their lineage even in environments where mates are scarce.
limited mobility in animals
Limited mobility can significantly affect an animal's ability to reproduce. Animals with restricted movement often inhabit environments where locating a mate is not only time-consuming but can also be risky.

For such animals, having reproductive strategies that mitigate these challenges is crucial for their survival and continuation. This is where hermaphroditism becomes particularly useful. By having both male and female reproductive organs, an animal doesn't need to search for a mate extensively.

In addition to hermaphroditism, some animals with limited mobility may use other strategies such as releasing gametes into their environment to increase the likelihood of fertilization by a nearby individual. Nonetheless, hermaphroditism stands out for its ability to guarantee reproduction in solitary conditions.
sexual reproduction
Sexual reproduction is a biological process where organisms produce offspring by combining genetic material from two different sexes. This method of reproduction introduces genetic diversity, which is beneficial for the adaptability and survival of species.

Typically, sexual reproduction requires two individuals: a male and a female. However, for animals with limited mobility, locating a member of the opposite sex can be challenging. This is where the strategy of hermaphroditism comes into play.

Hermaphroditism allows for sexual reproduction without the necessity of finding a partner of the opposite sex. This versatility means that even with limited mobility, these animals can maintain the benefits of genetic diversity while ensuring their reproductive success.

Sexual reproduction, enhanced by strategies like hermaphroditism, ensures that even animals that can't move much can still thrive and evolve over time.

Most popular questions from this chapter

Explain the mechanisms by which hormones from the brain and ovaries interact, eventually leading to menstruation. a. After the release of the egg from the follicle, the corpus luteum is formed, which inhibits FSH and LH production, which then inhibits GnRH production, causing no other follicle to develop. When no fertilization takes place, the corpus luteum degenerates and the progesterone level declines, initiating the breakdown of the myometrium and the start of the menstrual cycle. b. After the release of the egg from the follicle, the corpus luteum is formed, which inhibits FSH and LH production, which then inhibits GnRH production, causing no other follicle to develop. When no fertilization takes place, the corpus luteum degenerates and the progesterone level declines, initiating the breakdown of the endometrium and the start of the menstrual cycle. c. After the release of the egg from the follicle, the corpus luteum is formed, which inhibits FSH and LH production, which then facilitates GnRH production, causing no other follicle to develop. When no fertilization takes place, the corpus luteum degenerates and the progesterone level declines, initiating the breakdown of the endometrium and the start of the menstrual cycle. d. After the release of the egg from the follicle, the corpus luteum is formed, which inhibits FSH and LH production, which then inhibits GnRH production, causing no other follicle to develop. When no fertilization takes place, the corpus luteum degenerates and the progesterone level rises, initiating the breakdown of the endometrium and the start of the menstrual cycle.

During organogenesis, the ectoderm forms the neural cells and the epidermal cells. How do the ectoderm cells determine which type of cells to form? a. Growth factors signal some of the ectodermal cells to form epidermal cells, and the remaining cells form the neural plate. b. The notochord cells of the mesoderm signal the ectodermal cells to form epidermal cells as well as the neural plate. c. Growth factors signal some of the ectodermal cells to form epidermal cells, and the remaining cells form neural crest cells. d. Proteins involved in the Wnt signaling pathway signal the ectodermal cells to form the epidermal cells and the neural plate.

Compare and contrast sex determination in birds and mammals. a. In mammals, sex is determined by the presence of XX (homozygous) in males and XY (heterozygous) in females, while in birds, sex is determined by the presence of ZZ (homozygous) in females and ZW (heterozygous) in males. b. In mammals, sex is determined by the presence of XX (homozygous) in males and XY (heterozygous) in females, while in birds, sex is determined by the presence of ZW (heterozygous) in females and ZZ (homozygous) in males. c. In mammals, sex is determined by the presence of XX (homozygous) in females and XY (heterozygous) in males, while in birds, sex is determined by the presence of ZZ (homozygous) in females and ZW (heterozygous) in males. d. In mammals, sex is determined by the presence of XX (homozygous) in females and XY (heterozygous) in males, while in birds, sex is determined by the presence of ZW (heterozygous) in females and ZZ (homozygous) in males.

How does the feedback mechanism of hormones lead to muscular contractions during labor? a. A feedback relay occurs between the uterus, hypothalamus, and posterior pituitary to assure an adequate supply of oxytocin, which causes the contraction of smooth muscles of the uterus, leading to the birth of the baby. b. The posterior pituitary continuously produces oxytocin, which is sufficient for muscular contraction in the uterus, thereby causing the birth of the baby. c. A feedback relay occurs between the uterus, hypothalamus, and posterior pituitary to assure an adequate supply of prolactin, which causes the contraction of the smooth muscles of the uterus, leading to the birth of the baby. d. A feedback relay occurs between the uterus, hypothalamus, and posterior pituitary to assure an adequate supply of progesterone, which causes the contraction of the smooth muscles of the uterus, leading to the birth of the baby.

What is the advantage of sexual reproduction? a. Sexual reproduction allows animals to conserve resources and reproduce only during optimal conditions. b. Sexual reproduction results in offspring with diverse phenotypes, which may enhance survival of a population in a changing environment. c. Sexual reproduction guarantees that both parents will provide parental care. d. Sexual reproduction yields more numerous offspring more rapidly than is possible with asexual reproduction.
