23
Q

Oogonia differentiate into _________, which together with the surrounding gramulosa cells make up a follicle

A

Primary oocytes

24
Q

The_______ is ejected from the ovary during ovulation, and the part of the follicle remaining in the ovary develops into the corpus luteum, a temporary endocrine gland.

Secondary oocyte

25
Q

In ___________ reproduction
- A single individual gives rise to offspring
- There is no genetic input from another individual

A

Asexual

26
Q

In _________ reproduction
- male and female parents produce offspring through the fusion of gametes (egg and sperm) generated by meiosis

A

Sexual

27
Q

The parent separates into two or more offspring of approximately equal size example, planarians

A

Fission

28
Q

A new individual develops while attached to the parent - offspring may free from the parent, or remain attained to form a colony (hydra)

A

Budding

29
Q

Pieces separate from the body of a parent and develop (regenerate) into new individuals (ex: flatworms, annelids, and some echinoderms)

A

Fragmentation

30
Q

° some animals produce offspring by development of an egg without fertilization

° because the egg is produced by meiosis in the female parent, the offspring are not genetically identical to the parent or to each other

A

Parthenogenesis

31
Q

The formation of male and female gametes

A

Gametogenesis

32
Q

Formation of sperms in males

A

Spermatogenesis

33
Q

Formation of ova or eggs in females

A

Oogenesis

34
Q

Fusion of a haploid sperm and egg during fertilization produces a diploid _______, the first cell of a new individual

A

Zygote

35
Q

_________ a cell line that is set aside early in embryonic development and remains distinct from other body cells (somatic cells)

A

Germ cells

36
Q

Germ cells are located in specialized gamete - producing organs

A

Gonads

37
Q

In _______ reproduction, a single individual gives rise to offspring without fusion of gametes (egg and sperm)

A

asexual

38
Q

The offspring therefore are genetically identical to one another and to the parent. In other words, they are genetic clones of the parent and asexual reproduction of this kind is also called

A

Cional reproduction

39
Q

Some animals produce offspring by the growth and development of an egg without fertilization, a form of asexual reproduction called ___________

A

Parthenogenesis

40
Q

The formation of male and female gametes

A

Gametogenesis

41
Q

Gametes in most animals form from _______, a cell line that is set aside early in embryonic development and remains distinct from the other, somatic cells of the body

A

Germ cells

42
Q

Mitotic divisions of the germ cells produce spermatogonia in males and ______ in females

A

Oogonia

43
Q

The fusion of a haploid sperm and egg duringfertilization restores the diploid number of chromosomes and produces a _____, the first cell of a new individual

A

Zygote

44
Q

When the corpus luteum degenerates, menstruation begins due to

A

A drop in progesterone levels

45
Q

Ovulation where the maturing egg is released from the follicle is stimulated by an increase in

A

Lutenizing hormone

46
Q

The formation of male and female gametes is called fertilization

A

False

47
Q

Oogonia differentiate into ___________ which together with the surrounding _________ make up a __________

A

Oogonia differentiate into primary oocytes, which together with the surrounding granulosa cells make up a follicles

48
Q

Which of the following are mostly effective methods of contraception?

A

Condoms
Contraceptive diaphragms
Hormonal contraceptives
Intrauterine devices

49
Q

How many mature sperm are usually formed from each primary spermatocyte?

A

Four
