Answer:
Fruit (pods or hulls etc) bearing seeds are a means of dispersal for plants because they are sessile and have no means to move once germination anchors them with roots. Seeds are the dormant propagules or the quiescent, dispersing agents of the next generation that travel away from the parent plant in a disposal. This is why fruit/seeds are categorized by their dispersal by wind (hydrochoric) or by animals (zoochoric).
Explanation:
Answer:
a. one allele from each parent
Explanation:
According to Mendel, gametes are always pure and contain one allele for each gene. Let's assume that the genotype of the tall plant is "TT" and the genotype of the short plant is "tt". The tall plant would produce all the gametes with one copy of the "T" allele while all the gametes from the short plant would carry only the "t" allele.
The random fusion of gametes from tall and short parent plant produces all the F1 progeny with genotype "Tt". Here, each F1 plant obtained one "T" allele from the tall parent plant and one "t" allele from the short parent plant.
Answer:
It means that the cell membrane only lets some molecules/substances through the phospholipid bilayer.
Explanation:
I would say Dwayne. That’s my final answer
The theory of plate tectonics evolved from the previous theory of continental drift. Alfred Wegener came up with the latter theory in comparing the coastline shapes of for example eastern South America with western Africa they seemed to fit together. However, there was no mechanism for this until I believe in the late 1960's or early 1970's the theory of plate tectonics was developed which the Canadian geophysicist played a part in J. Tuzo Wilson. The latter theory shows how the mid-oceanic ridges are spreading and the continental margins have the ocean floor subducting.
