Answer:
Since Yellow is dominant over green then almost all of the children will have yellow faces. The punnet square below will show what the offspring will have but my guess is
50% will have yellow faces
50% will have both yellow and green
1% will have a green face
But since Yellow is dominant over green the 50% of both colors will mostly show a yellow dominant.
I apologize if my drawing looks messy.
Hope this is correct
The limitation of triangulation is it is not accurate to calculate stellar distance.
Explanation:
- In case of triangulation method no specific or uniform method is used . The scientist who use triangulation to measure stellar distance becomes unable to say what type of technique they are using to find the distance. The triangulation method is a combination of various techniques.
- Triangulation can be divided into four parts, they are Data triangulation, theory triangulation, investigator triangulation and lastly methodological triangulation. Triangulation method is used in creating innovative ways.
Answer:
Darwin's theory of natural selection lacked the physical proof of the intermittent species as suggested by him. The fossils of such species had not been discovered by the time he wrote his book 'Origin of species'. In order to defend his theory, he pointed out the non-reliability on fossils.
Explanation:
The field of geology was just evolving at the time Darwin wrote his book, and no fossils supporting his theory has been discovered yet. He defended his theory by saying that the fossils cannot be depended on for the proof of evolution as the the process of fossilization depends on many factors, and the available fossils are very rare. The irregularities in the geological records, also suggested that the fossil records are not perfect.
Defending his theory, he shows how, if available. the fossil records can support his theory. The fossils should show the features of both the extinct (parent species ) species and the present species, as the species present in today's world have evolved from the ones that existed long before them through the process of natural selection.
The discovery of the Archaeopteryx in 1861 supported his theory and the process of evolution as it showed the features of both the reptiles and birds.
Explanation:
The large size of a egg makes it difficult for the female to retain more than a single one egg at a time - carrying eggs would make flying harder and require more energy. (Bird eggs vary in size from the tiny 0.2 gramme eggs of hummingbirds to the enormous 9 kilogram eggs of the extinct elephant bird.)
Just as an aircraft cannot fly if it is overweight, all female birds must dispense with the fertile egg as soon as it is formed. And because the egg is such a protein-rich high-nuitrition prize to all sorts of predators, birds must find a secure place to hatch their eggs. Although birds' eggs appear to be fragile, they are in fact extremely robust. The oval shape applies the same rules of engineering as an arched bridge; the convex surface can withstand considerable pressure without breaking. This is essential if the egg is not to crack under the weight of the sitting bird. It takes 26 pounds of pressure to break a swan's egg and 120 pounds to smash the egg of an ostrich.
