Answer:
The Visible Light Spectrum and the differences in wavelength and appearance.
Explanation:
I stated this by using the concept of the visible light spectrum. As indicated already in reference to the statements provided, you are observing what is known as the visible light spectrum. This is indicated because the visible light spectrum obtains all the colors of the rainbow and not only that but the statements even use key terms such as wavelengths and different color components. Therefore, signifying that you are looking at the visible light spectrum and observing it on an appearance based observation based on background facts and scientific knowledge. To further evaluate the visible light spectrum in terms of wavelength, both statements A and D provide information regarding the differentiation within wavelengths based on the color in which one perceives. Whereas B and C simply state scientific facts about how the rainbow appears.
The roots need all the water it can get but sense theres water in the ground it already has water which transports water to the leaves
Answer:
There are many types of evidence which support the theory of evolution such as comparative anatomy, fossil records, phylogenetic relationship, embryology et cetera
Comparative anatomy includes homologous organs and analogous organs. They support divergent and convergent evolution respectively.
For example, the homologous structure of limb of humans, birds, bat, horse, whale et cetera show that they are made up of the same set of bones which are humerus, radius, ulna, carpals, metacarpals, and phalanges.
It shows divergent evolution and supports that these organisms have evolved from a common ancestor.
Embryological evidence: When early stages of embryological development of different organisms are compared, it is found that these stages are similar at different levels of development.
For example:
- The appearance of pharyngeal-arch (gill-like structures) in vertebrates during embryo development.
- Salamanders and terrestrial frogs pass through larval stages within an egg. They possess the features similar to aquatic larvae, however, when they hatched out the eggs being ready for life on land.
Answer:
The statements which are correct are:
-85% of the U.S. corn is GMO; modified to be resistant to herbicides.
-Technology now allows us to transfer genes between organisms of different species and even kingdoms.
- Extensive testing has been conducted on GMO-foods to ensure that there will be no adverse allergic reactions or health risks.
Explanation:
GM foods can be described as the food which is genetically modified. In simpler terms, food prepared by the introduction of a foreign gene is termed as genetically modified food.
About 92 percent of the corn produced in the U.S is genetically modified and out of it about 85 percent is genetically modified to be resistant against herbicides.
The use of GM foods was made legal after passing through various tests in the laboratory and being approved by the FDA. Up till now, any food prepared by this method is properly tested and approved By FDA before introducing it into the market.
