Answer:
We can see some of the most important patterns Darwin noticed in distribution of organisms by looking at his observations of the Galápagos Islands off the coast of Ecuador. Darwin found that nearby islands in the Galápagos had similar but nonidentical species of finches living on them.
Answer:
Main function of phloem Transportation of food particles.
Explanation:
Phloem is the living vascular tissue in plants. Phloem is also known as bast. Phloem is responsible for transporting food to parts of the plant where needed. It's mainly transport sugar sucrose which is made by photosynthesis. This transport process is called translocation. In trees the phloem is the innermost layer of the bark.
Answer:
3 yellow : 1 green
Explanation:
Let yellow seed trait be represented by Y allele and green seed trait by y allele.
Purebred yellow seed plant = YY
Purebred green seed plant = yy
YY x yy = Yy, Yy, Yy, Yy (all yellow)
This thus means that yellow seed trait is dominant over green seed trait.
F1 x F1 = Yy x Yy, resulting in YY, Yy, Yy, yy offspring.
Since Y is dominant over y,
YY, Yy, Yy = Yellow
yy = green
<em>Hence, the expected phenotypic ratio of seed color of the offspring of F1 x F1 cross is </em><em>3 yellow : 1 green</em>
