The process that tend to reduceb the variety within a population is called B. Random fertilization.
Months with higher temperature have more rainfall.
Explanation:
From the presented graph, we can see that all three parameters are following a same trend. When the maximum temperatures increase, the minimum temperatures increase too, and the rainfall increases as well. When the maximum temperatures decrease, the minimum temperatures decrease, and the rainfall decreases too.
There is a simple explanation for the connection of higher temperature and more rainfall in Scotland. Scotland is located on an island, thus it is heavily influenced by the sea. When the temperature is higher, the humidity is higher, and in accordance to that more rainfall occurs. When the temperature is lower, the humidity is lower, so there is less rainfall, or instead of rainfall the precipitation can be manifested as snowfall.
Answer:
Sympathetic Nervous System
Explanation:
The main function of the sympathetic nervous system is to stimulate the fight or flight response.
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.
