1) Bacteria respond to changes in their environments, such as nutrient availability, by regulating their metabolic pathways. Des
nasty-shy [4]

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.

What is the island of Hispanola named today?
12345 [234]


The Correct  answer is C.

The Island of Hispaniola is the second largest island in the Caribbean, at 29, 237sq miles. Haiti occupies about 1/3 of the Island while the Dominican Republic controls the balance of the land.

Christopher Columbus claimed Hispaniola in 1492, declaring it  "the most beautiful island in the world".  It later became the launching base for the Spanish conquest of the Caribbean, as well as the American mainland. 

The western third of the island became known as Haiti in 1804 and while the remainder became known as the Dominican Republic in 1844.
