This question lacks options, the options are:
A. Halved
B. Doubled (x2)
C. Quadrupled (x4)
D. Octupled (x8)
The answer is B.
Explanation:
Via the process of meiosis, gametes are formed in order for sexual reproduction to occur. However, the chromosomal content of the gametes are reduced by half. According to this question, a germ cell is said to have 2 sets of chromosomes i.e. diploid, meaning that each daughter cell after meiosis will have one set of chromosome (haploid, n).
However, before any form of division can occur, the DNA (genetic material) of the cell must be replicated i.e. doubled in order to ensure that each resulting gamete has enough chromosomes. This is applicable in this question as well as the DNA in the germ cell must be DOUBLED (×2) via replication in order to have enough DNA for each gamete.
I think it’s m(C6H12O6) = 856 g
M(C6H12O6) = 12*6+1*12+16*6 = 180 g/mol
n(C6H12O6) = m/M = 856 g / 180 g/mol = 4.756 mol
n(CO2) = 6*4.756 = 28.536 mol
M(CO2) = 12+16*2 = 44 g/mol
m(CO2) = n*M = 28.536mol*44g/mol = 1255.584 g
Answer:
Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote. Recombination or crossing over occurs during prophase
Answer: Option E
Maintaining very long telomeres promotes cancer cell formation.
Explanation:
Telomere refers to either of the sequences of DNA at each end of a eukaryotic chromosome.
Usually, in eukaryote chromosome replication, telomeres are not replicated.
Hence, they are usually lost resulting in the shortening of the telomere ends after repeated cycle of cell division. This also leads to cell aging and stoppage of cell division.
The shortening of telomere combined with stoppage of cell division, and cell aging initiation prevent CANCER, which thrives on lengthy telomeres
I don't think that is right !!! .....some planktons can be eaten and it is not release cO2 back in air. so false !
