Answer 7

Hermaphroditism,
separate sexes,
external fertilization,
internal fertilization

Question 8

Asexual reproduction

Answer 8

Production of offspring without gamete fusion

Ex) budding, fission and fragmentation with regeneration

Question 9

Parthenogenesis

Answer 9

Form of Asexual reproduction where one gamete creates it own embryo without the inclusion of another gamete

Question 10

What controls reproductive cycles

Answer 10

Hormones and environmental cues

Question 11

When does fertilization occur

Answer 11

When sperm and egg are both released outside the body or when sperm is deposited by the male into the female eggs

Question 12

What type of fertilization is associated by fewer offspring but greater parental protection

Answer 12

Internal fertilization

Question 13

Look@ human game to genesis flow chart

Question 26

Human sexuality includes

Answer 26

Biological sex, gender identity andsexual orientation

Question 27

In mammals what hormone in the hypothalamus regulates the release of FSH and LH from anterior pituitary

Answer 27

GnRH

Question 28

What do FSH AND LH control in male mammals

Answer 28

Control the secretion of androgens(LH), mainly testosterone, and spermicide production

Question 29

What does FSH AND LH control in females

Answer 29

Controls the ovarian and uterine cycles via estrogen (mainly estradiol) and progesterone

Question 30

The developing ovarian follicle and corpus luteum also

Answer 30

Secrete horomones which further helps coordinate the period cycle through positive and negative feedback

Question 31

The estrous cycle

Answer 31

The reproductive cycle in rodents

Question 32

What happens to the endometrium lining in rats

Answer 32

They are reabsorbed and sexual receptivity is limited to a heat period

Question 33

Journey to blastocyst

Answer 33

Fertilization—> meiosis in oviduct—> zygote cell division —> blastocyst develops before implantation in endometrium
