Answer:
In 1964 2.6 bales per hectare while in 2008, 380 bushels per hectare.
Explanation:
in 1964, the average corn yield was 2.6 bales per hectare which is equals to 570 kg per hectare while in 2008, the average yield of corn was 380 bushels per hectare which is equals to 9655 kg per hectare. This increase in the productivity of corn crop is due to advancement of technology, high yielding seed varieties and reduces post harvest losses. The yield of 2008 is 17 times higher than 1964.
Answer:
Yes...This is an example of speciation by natural selection
Explanation:
As we know that natural selection always promote those evolutionary changes that are necessary. Changes that happen in chromosome number always promote with a specie that is closely related to the parent specie and produce fertile off-springs. These new generations are most adaptable and can survive in the environment more efficiently than the previous ones.
Additionally, other than natural selection, speciation can also happen as a result of random mutations, genetic drift and by means of artificial selection as well. But the natural likelihood of all these is probably low as compared to that of natural selection.
<span>The F2 generation would have included a higher percentage of pea plants producing round, yellow peas. As the f2 generation included 315 plants producing round yellow peas, 108 with round green peas, 101 with wrinkled yellow peas, and 32 with wrinkled green peas which all are in the ratio 9:3:3:1.</span>
Answer:
temperature. humidity environment
Explanation:
species will adapt to environment temperature and humidity whether it is a rain forest or snowy mountains
Note each of them:
Archaea is a single-celled microorganism with no nucleus
Bacteria is a unicellular microorganism with cell walls but lack organelles
Sarcodina is a phylum with temporary extensions of the cell. They can be parasitic.
Protista is an eukaryotic organisms that is not an animal, plant, or fungus.
The organism found is unicellular (rules out Archaea), with cell walls (characteristics of bacteria), and the ability to produce spores.
I believe that Bacteria (B) is your best answer
hope this helps
