Question

Which bormone has the lowest concentration on which day? a.) hormone A on day 4 e ) hormone C on day 12 b.) hormone B on day 2 d) hormone D on day 20 development of an 10. Which sequence represents the correct order of processes that result in the formation embryo? a.) meiosis-> fertilization> mitosis c.) fertilization-> meiosis mitosis and b.) mitosis-> fertilization-> meiosis 11. The diagram below represents stages in the processes of reproduction and development in an animal. Cell containing only half of the genetic information characteristic of this species are found at a.) A b.) B c.) C d.) D 12-15. The human female reproductive system is represented in the diagram below. Complete boxes 1-4 in the chart below using the information from the dia Name of Structure Letter on Diagram Function of Structure 2. Produces gametes Uterus 3. Transports oxygen directly to the

Answer 1

9.b is correct because it represent the estrogen and at the end of the previous cycle, the gonadotropin-releasing hormone levels increase due to negative feedback of estrogen and progesterone (their levels drop right before periods), which also causes the increase of the follicle stimulating hormone levels.

10. (a) is correct because it is obvious that meiosis,the reduction division ,has to occur if a diploid body has to produce haploid gametes.After fertilization a diploid zygote form which undergo mitotic division to increase the number of cells in the developing embryo.

11.(a) A is correct because here fusion not occur and as we know that ovum and sperm are haploid due to meiosis.So they contain half genetic information.

12.1.ovary

2.C

3.implantation occur

4.placenta
