The answer is <span>bird droppings that contain seeds from a different location.
</span><span>Gene flow includes a transfer of alleles from one population to another. So imagine a population of plant A on location 1 and another population of plant A on location 2. They cannot interchange their genes. But if birds drop seeds from location 1 and those seeds get to location 2, gene flow may occur.</span>
The answer is <span>reuptake.
Reuptake is a term used when a neurotransmitter is taken back by the axon after being used. By doing reuptake, the synapse will be cleaned out of the neurotransmitter, making it stop giving the signal.
Some drug target reuptake mechanism like serotonin reuptake inhibitor that used for depression. This drug can increase serotonin by inhibiting the reuptake mechanism.</span>
You would need two plants at the least, one that you kept out side of sunlight and one in sunlight. I don't know how you would figure out how much Carbon Dioxide is used but the plant in the sunlight i believe would be the control. <span />
I suppose the yellow peg is facing the green peg, in which case the green peg must be guanine.
The bases are associated in pairs. In each pair there is always a purine associated with a pyrimidine. The association is by weak bonds: the hydrogen bonds, two bonds for an AT pair; three links for a GC pair. When we know the sequence of one strand we can deduce the sequence of the other strand. The two strands are oriented opposite to the 3 'and 5' ends (the strands are called antiparallel).
Answer:
The correct answer will be option- synaptonemal complex.
Explanation:
The tetrad arrangement of the genetic material in an organism is mediated by a highly conserved structure known as the synaptonemal complex. The synaptonemal complex is formed during the prophase I of the meiosis I which attaches the chromatin of the homologous chromosomes.
The synaptonemal complex is a proteinaceous structure which is formed by the two lateral ladders like elements with a central portion composed of the central element. The chromatin gets attached to the lateral elements while the central a portion bridge space between the two ladders thus help in the formation of the tetrad.
Thus, option- synaptonemal complex is the correct answer.
