Concerning language development, which of the following statements is false?
a. The idea that language is learned is supported by the fact that children around the world use a limited number of patterns in their first sentences.
b. The typical patterns of children’s first sentences include identification, nonexistence, possession, agent-action, negation, and question.
c. A readiness to interact socially with parents may be as important as innate language recognition to language development.
d. Noam Chomsky overestimated the innate quality of language and underestimated the importance of learning.
Which of the following statements regarding early embryonic development is FALSE.
a. The embryo is normally at the zygote stage when it implants in the uterine wall.
b. Cleavage refers to mitotic cell divisions in the first 3 days.
c. The vast majority of cells that make up the embryo germ layers derive from the inner cell mass cells of the blastocyst.
d. One function of the yolk sac is to provide nutrients to the developing embryo.
e. None of the above.
Answer to question 1
Answer. The false statement is, about half of the oogonia complete mitosis between birth and puberty.
The mitosis occurs during 9 th to 22 nd week of embryonic devlopment during which the oogonia proliferate.later they either degenerate or further differentiate into primary oocytes through meiosis I. The primary oocyte remain dormant until puberty.
Other statements are true.
Before birth, the girls lost majority of the oocytes and some of them before puberty. By the time of puberty, there are only 300000 eggs remain out of which only 300 to 400 will ovulate test are degenerated.
The oogenesis begins before birth during the embryonic life from the primordial germ cells which devlop and differentiate into oogonia.
Oogonia is the stem cell that develop from the primordial stem cell during embryonic life. The oogonis under goes meiosis I and form primary oocytes which arrest their growth at prophase I until puberty.
The oocyte is arrested at metaphase of meiosis II after ovulation which is completed after fertilization that form mature ovum and second polar body.
Answer to question 2
The correct solution to this problem is provided by option A: the idea that language is learned is supported by the fact that children around the world use a limited number of patterns in their first sentences.
To elaborate, the learning perspective of language development is actually weakened by the fact that children around the world use a limited number of patterns in their first sentences. That fact actually supports that nativists’ perspective of language development.
Answer to question 3
The statement regarding early embryonic development that is false is answer option A. The embryo is normally at the zygote stage when it implants in the uterine wall. A zygote is the initial fertilized egg cell that has not divided yet. The stage at which the embryo implants into the uterine lining is during blastulation when the embryo is considered a blastocyst.
