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 correctly describes hermaphroditism? A. It is an example of sexual reproduction because it involves a male and a female. B. It is an example of asexual reproduction because only one individual needs to be involved. C. It is an example of sexual reproduction because it involves fusion of two gametes. D. It is an example of asexual reproduction because the offspring are genetically identical to the parent.
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
Binary fission is a form of asexual reproduction. What is an advantage of asexual reproduction when compared to sexual reproduction? a Asexual organisms are less likely to have mutations in their DNA than sexual organisms are. b An organism that reproduces asexually can reproduce much more quickly than an organism that reproduces sexually. c An asexual organism lives longer than an organism that reproduces sexually. d An organism that reproduces asexually is better equipped to respond to environmental changes than an organism that reproduces sexually.
Birth control pills are oral contraceptives taken by women to prevent pregnancies. The most effective forms of birth control pills contain estrogen and a small amount of progestin (a synthetic hormone that mimics the effects of progesterone). Although the most effective forms of oral contraceptive for women contain estrogen and progestin, some birth control pills contain a small dose of progestin only. This is because there are many risks and side effects associated with estrogen.Which of the following statements is NOT a reason for using a progestin-only oral contraceptive? Select one: a. Progesterone suppresses the maturation of follicles, thereby preventing ovulation of a mature ovum. b. Progesterone maintains the corpus luteum as corpus luteum releases a large amount of progesterone and some estrogen. c. Progestin-only oral contraceptives prevent the production of FSH and LH in the anterior pituitary. d. Progesterone suppresses the production of GnRH in the hypothalamus.
Which of the following statements does NOT correctly describe the similarities and differences between male and female reproductive systems? Select one: a. Millions of mature sperm are produced on a daily basis, whereas single mature ovum is released every 28 days. b. Meiosis is completed in eggs after fertilization begins, whereas a mature sperm has completed meiosis prior to fertilization. c. Eggs and sperm contain exactly half of the genetic material of a normal somatic cell. Many zygotes with an abnormal number of genetic material often do not successfully implant. d. Eggs and sperm can survive for 3 to 5 days in the Fallopian tubes.
Which of the following scenarios does NOT describe an event that leads to the conception of twins? Select one: a. Two eggs are fertilized by two sperm cells, resulting in fraternal twins. b. Two eggs are fertilized by one sperm cell, resulting in monozygotic twins. c. High levels of FSH stimulates maturation of three ovums. d. One egg is fertilized by one sperm but divides into two zygotes, resulting in two babies of the same gender.
A paradox of sexual reproduction is that despite its being widespread in nature, the question of why it exists at all is still unresolved. What are some disadvantages of sex? What are some consequences of sex that make it so important?
Which of the following statements does NOT correctly describe a difference between the male and female reproductive systems? Select one: a. Testosterone has a major role in the development of secondary sexual characteristics in male reproductive systems, whereas LH promotes the development of secondary sexual characteristics in females. b. The male reproductive system mass produces large quantities of gametes each day, whereas the female reproductive system produces an average of a single gamete each month. c. The excretory and reproductive systems both use the urethra in males, whereas in females, there are separate tubes for the excretory and reproductive systems. d. The structures that produce gametes are exterior to the body in the male reproductive system, whereas the gametes are produced inside the body for females.
Compare and contrast sexual and asexual reproduction. Identify the most accurate statement. a. Asexual reproduction results in more offspring per mother. b. Sexual reproduction is always more costly. c. Sexual reproduction is associated with an increase in homozygosity. d. Asexual reproduction is always bad for a species.
Which of the following is a advantage of asexual reproduction? a.)Same DNA being passed down-NO GENETIC VARIATION IN THE OFFSPRING b.)If parent has genetic disease offspring will have it too c.)Only one parent involved. No searching for mates d.)Requires more cellular energy
Which of the following scenarios does NOT describe an event that leads to the conceptions of twins? Select one: A. two eggs are fertilized by two sperm cells, resulting in a fraternal twin. B. High levels of FSH stimulate the maturation of three ovums. C. Two eggs are fertilized by one sperm cell, resulting in a monozygotic twin. D. One egg is fertilized by one sperm but divides into two zygotes, resulting in two babies of the same gender.
