Answer 2

Organogenesis

Question 3

Cell division

Answer 3

Proliferation

Question 4

Cell differentiation

Answer 4

Specialization

Question 5

Branch of embryology that deals with the cause and results of abnormal development or congenital malformation.

Answer 5

Teratology

Question 7

Result of cells expressing some genes and suppressing others within a common genome.

Answer 7

Cell differentiation

Question 9

Abnormality arise during prenatal development

Answer 9

Congenital malformation or congenital defect

Question 10

Cell division that results in two daughter cells having diploid number of chromosomes that are identical to the parent cell.

Answer 10

Mitosis

Question 11

Cell differ because they produce different proteins such as:

Answer 11

Structural composition
Enzymes
Secretory products
Channels and pumps
Receptors

Question 12

Developmental disturbance that involves an organ or portion of an organ

Answer 12

Anomaly

Question 13

Where is the non mitotic cell located in?

Answer 13

Interphase stage

Question 14

Chromosomes condense and become visible; nuclear membrane disappears under the light microscope.

Answer 14

Prophase

Question 15

Individual, double-chromatid chromosomes align randomly at the equatorial region between centrioles.

Answer 15

Metaphase

Question 16

Two chromatids per chromosome separate as the centromere divides and each chromatid becomes a chromosome in a new nucleus

Answer 16

Anaphase

Question 17

Cytoplasm divides (cytokinesis); cell membrane divides; chromosomes become invisible and the nuclear membrane reappears.

Answer 17

Telophase

Has two diploid cells having haploid number of chromosomes

Answer 18

Meiosis

Answer 23

Mesenchyme

Question 24

Group of loosely and irregularly arranged embryonic stellate cells separated by an extensive extracellular cells.

Answer 24

Mesenchyme

Question 25

Three facts about a mesenchyme?

Answer 25

Present in the embryo.
May differentiate into a epithelium.
Differentiate into adult structure as the embryo grows.

Question 26

Tissue that connects and support other tissues of the body?

Answer 26

Connective tissue

Question 27

All develop in sequential manner from a fertilized?

Answer 27

Ovum

Question 28

Characteristics common to all vertebrate embryos

Answer 28

All develop in sequential manner from a fertilized ovum. All share similar structures. All pass through a common stage of development during which they present similar anatomical features.

Question 29

Removal of proteins that cover the sperm also increases sperm motility.

Answer 29

Sperm capacitation
