The following phenotypic classes reflect offspring that were generated as a result of a crossover event
- miniature wings
- garnet eyes
Explanation:
When the miniature wings and garnet eyes links up with the 8 map unit that are present between them. After that the presence of two recombinant classes must complement together and make 8% of total i.e. they contribute 4% each. together the parental classes make up to 92% by contributing 46% one.
This can be understood through a phenotypic ratio calculation, which can be expected from it.
wild type: 4% x 800 = 32
miniature wings: 46% x 800 = 368
garnet eyes: 46% x 800 = 368
miniature wings, garnet eyes: 4% x 800 = 368
Out of the choices given, the two Middle Eastern people that can be referred to as a Semite is the Jews and the Persians. This will make the correct answer D.
C. Changes to biodiversity can positively and negatively affect an ecosystem.
Photosynthesis and respiration are reactions that complement each other in the environment.
Answer:
The correct answer is - Fossil fuels are cheaper than alternative forms of energy.
Explanation:
Fossil fuels are made by the natural process in a longer time period such as anaerobic decomposition of the dead organism like plants, and animals. These plants and animal's decomposed organic matter pilled up to form coal, or natural gases or crude oil.
By the use of such fuels the reserves are continuously depleting and will be no longer available in the future if not managed properly as it can not be renewed. Fossil fuels increases the green house gases in environment and affect it by incresing carbon in atmosphere. However, these fuels are cheaper in comparision of other fuels.
Thus, the correct answer is - Fossil fuels are cheaper than alternative forms of energy.
