Answer:
III. Equal number of chromosomes.
Explanation:
Comparison between two cells, one cell just before first meiotic division and other cell ready to start mitosis is that both the cells have equal number of chromosomes.
Both the cells have an equal number of chromosomes that is 2n (diploid), where n is 23 and total chromosomes are 46 in each cell but at the meiosis at the end meiosis produces four haploid (n) daughter cells and mitosis produces two diploid (2n) cells.
Hence, the correct answer is "III. Equal number of chromosomes.".
Endoderm is the correct answer.
glad i could help(:
Answer:
(B) semiconservative.
Explanation:
According to the model proposed by Watson and Crick, the DNA molecule consists of two polynucleotide chains arranged on a helix around an imaginary axis, rotating to the right (a double helix). That is, the DNA molecule is in the shape of a spiral staircase, in which the "steps" are made up of nucleotide nitrogen bases and the "handrails" are covalently linked phosphate and sugar - so it is said that DNA is shaped like a helical ribbon. Also according to Watson and Crick DNA replication is semi-conservative, because each strand of DNA will give rise to another strand that will be complementary to its nucleotides.
A plasma (cell) membrane, a nucleus, mitochondria, internal membrane bound organelles and a cytoskeleton.
