Answer: D. DDT bioaccumulates
Bioaccumulation is the accumulation of substances or compounds such as pesticides, fertilizers or other chemicals in the body of the organisms. These substances or compounds are toxic and remain undigested in the body of the organisms are transferred subsequently in a food chain, when one organism is consumed by another organism. The highest trophic level is most effected because of the concentration of the toxic substance is the maximum.
DDT (dichlorodiphenyltrichloroethane) is a colorless, odorless and tasteless crystalline chemical compound. It is used as a pesticide to kill pests in agricultural field. DDT is highly toxic chemical compound. It remains undigested in the body of the organism and transferred in a food chain when one organism is consumed by another organism. The effect of DDT is magnified several times in the top most trophic level in the food chain due to bioaccumulation.
B. Classification can change with new discoveries and evidence.
C. Classification does not change with more evidence.
D. Phylogenetic trees are inaccurate.
Answer;
B. Classification can change with new discoveries and evidence.
Explanation;
-Classifying organisms on the basis of descent from a common ancestor is called phylogenetic classification
-A phylogenetic tree is a visual representation of the relationship between different organisms, showing the path through evolutionary time from a common ancestor to different descendants. Trees can represent relationships ranging from the entire history of life on earth, down to individuals in a population.
B - Mitosis
C - Meiosis
D - Chemiosmosis
2) The final product of _______ is glucose.
A - Cellular respiration
B - The light dependent reaction
C - The Calvin cycle
D - None of the above
True
or
False
Answer:
The correct answer would be :
b. Microbes can be blocked from accessing favorable growth environments.
d. Microbial life can be destroyed by heat.
e. Microorganisms can be present in nonliving matter, such as air, liquids, and solids.
g. Pasteur's observations support the theory of biogenesis.
Explanation:
Pasteur's experiment with s-shaped neck flasks indicated that organisms can't emerge from nonliving materials under the conditions that existed on Earth during his lifetime.
It helps in testing the role of airborne contaminants in producing microbes in the nonliving matter by the biogenesis theory. His experiment showed and supports that heat can kill or destroy microbial life.
Thus, the correct answer would be - b., d, e., and g.
Pasteur's experiments using S-shaped neck flasks led to several conclusions: microorganisms can be blocked from accessing favorable growth environments, microbial life can be destroyed by heat, microorganisms can be present in nonliving matter, and Pasteur's observations support the theory of biogenesis.
