5. Animals which produce one or two egg cells during a single reproductive cyde are most likely to have (1) extemal fertilization & much parental care of young, (2) extemal fertilization & little parental care of young, (3) intemal developrment & Íittle parental care of young, (4) internal fertilization & much parental care of young 6. In frogs, zygote formation nomally occurs in the (1) ơvary, (2) oviduct, (3) extenal environment, (4) intemal environment 7. Generally, animals that cary on extemal fertilization (1) produce more eggs than animals camying on intemal fertilization, (2) have much parental care of the young, (3) have little yolk in the eggs, (4) live on land

Hi, I'm trying to get some assistance for these questions:
Transcribed Image Text:5. Animals which produce one or two egg cells during a single reproductive cycle are most likely
to have (1) extemal ferilization & much parental care of young, (2) extemal fertilization &
little parental care of young, (3) intemal developrment & ittle parental care of young, (4)
internal fertilization & much parental care of young
6. In frogs, zygote formation normally occurs in the (1) ovary, (2) oviduct, (3) external
environment, (4) intemal environment
7. Generally, animals that camy on extemal fertilization (1) produce more eggs than animals
carying on intemal fertilization, (2) have much parental care of the young, (3) have little yolk
in the eggs, (4) live on land
8. Which is an important adaptation for reproduction among land animals? (1) fertilization of
gametes outside the body of the female, (2) fertilization of gametes within the body of the
female, (3) production of spem cells with thick cell walls, (4) production of spem cells with
thin cell walls
9. Which is the correct sequence in the development of an animal embryo? (1) cleavage,
blastula, fertilization, gastrula, (2) gastrula, fertilization, blastula, deavage, (3) fertilization,
cleavage, blastula, gastrula, (4) fertilization, deavage, gastrula, blastula
10. From which human embryonic layer do the epidemis of the skin and the nervous system
develop? (1) ecdoderm, (2) blastula, (3) mesodem, (4) gastrula
11. The endodem of the gastrula gives rise to the (1) blood and blood-vessels, (2) muscles, (3)-
brain & nérvous system, (4) digestive system
12. The holow ball stage in embryo development is called the (1) blastula, (2) morula,

parent cell, has (1) more cytoplasm, (2)less cytoplasm, (3) more chromosomes, (4) fewer
chromosornes
(1) they Iive near
14. Which generally characterizes animals that cary on extemal fertilization?
water, (2) they give exténsive care to their newbom, (3) they have fewer offspring than
animals which cary on intemal fertilization, (4) they produce nonmotile male gametes
