Answer:
Complex organisms evolved from more simple organisms
Explanation:
<em>Fossil records support the fact that complex organisms evolved from more simple organisms.</em>
<u>Fossils are remains of organisms that have been naturally preserved in rock forms. </u>
The study of fossilized remains of organisms has enabled scientists to establish the fact that earlier organisms are simple types and more complex organisms arose from them through a gradual process of change, otherwise known as evolution. Carbon dating of fossils enables scientists to establish the year the organism existed.
I believe the answer is A!
Answer:
<em>The correct option is A) if the research uses anonymous questionnaires</em>
Explanation:
For research studies, it is always important that the consent of the participants be taken if they are to be mentioned in the research. Without the consent of a person, a researcher cannot use anything related to that person in his research. However, in scenarios where you have to keep the data anonymous and just depict the results, consent is not necessary. However, one should recognize that apart from anonymous studies, not taking consent of the participants is unethical.
Answer:
Image result for Two differences between primary and secondary metabolites
Primary metabolites are not species-specific and thus might be identical in some organisms. Secondary metabolites are species-specific and thus are different in different organisms. Primary metabolites are involved in the growth, development, and reproduction of organisms.Aug 18, 2020
The answer is a C3 fixation.
Plants are located in different regions with a different condition, so they had to adapt the carbon fixation. There are three types of carbon fixation in plants - C3, C4, and CAM fixation. C3 and C4 plants open their stomata during the day while CAM plants open stomata during the night.
Plants in arid locations use CAM carbon fixation because of adaptation to water deficiency. In CAM plants, stomata are closed during the day and water loss is reduced. In the night when is colder, stomata open and carbon dioxide enters through stomata. In C4 carbon fixation, there is also adaptation to high temperatures thanks to enzymes that increase the rates of photorespiration, unlike the C3 fixation.
