Answer:
g. A cell model consisting of a circle containing four vertical pairs of lines attached at the middle, stacked in two rows of two.
Explanation:
In Metaphase I of the cells, homologous chromosome pairs are lined up next to each other which is defined as synapsis. Each pair of two chromosomes (bivalents) consists of four chromatids in total are positioned on the metaphase plate.
Metaphase I occurs when tetrads of chromosomes are lined up along the equator of the spindle. Spindle fibres are attached to the centromere region of each homologous chromosome pair. These homologous chromosomes consist of the matching alleles originating from mother and father.
In Metaphase I, meiotic recombination (''crossing over'') happens. Meiotic recombination means there is a genetic shuffling of the attributes of both parents. A result is a large number of possible genetic combinations. It is estimated that there is a 50-50 chance for the daughter cells to receive or mother's or father's homologous for each chromosome. In an organism with 2 sets of chromosomes, there are 4 ways in which the chromosomes may be arranged. This is resulting in differences in the chromosomal distribution in daughter cells after meiosis I.
The answer would be B made of one cell.
C matches with G and A matches with T, so:
TGACGGTA
matches with
ACTGCCAT
Answer:Over time, carbon-14 decays in predictable ways. And with the help of radiocarbon dating, researchers can use that decay as a kind of clock that allows them to peer into the past and determine absolute dates for everything from wood to food, pollen, poop, and even dead animals and humans.

Chlorophyll is the pigment
