Answer:
These characteristics are cellular organization , reproduction , metabolism , homeostasis , heredity , response to stimuli , growth and development, and adaptation through evolution.
Explanation:
Investigators should keep in mind that eyewitness identification is highly infallible. true, since the law takes the identification as a positive test and completely commits those involved and an error in it could tarnish the course of justice and consequently of the investigators.
C. Vestigial structure is the correct answer
Two examples of how the biosphere supports life is by reducing the amount of harmful radiation to reach the surface of the earth. It also gives oxygen for animals to breathe
Answer:
Examples:
- Short-term adaptation: feedback inhibition
- Long-term adaptation: regulation of gene expression
Explanation:
Feedback inhibition is a mechanism where the product of a chemical reaction is utilized to modulate its own subsequent synthesis. In bacteria, feedback inhibition allows regulating different metabolic pathways in response to environmental conditions by modulating enzyme activity through enzyme reaction products. Moreover, bacteria may also respond to environmental inputs by long-term changes in gene expression. For example, bacteria contain transcription factors activated during stress, which are able to activate the transcription of particular genes into messenger RNAs (mRNAs) that would subsequently be used to generate particular enzymes by the process of translation. These transcription factors may bind to specific DNA motifs in order to promote transcriptional activity, thereby regulating the production of the corresponding enzyme.
