Answer:A=V
Explanation:
It is used to move small or non polar molecules does not apply to facilitated diffusion. Small, non-polar molecules can diffuse directly across the phospholipid bilayer.
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.
I believe the answer would be meiosis
Answer:
The sun is the start of the water cycle
Explanation:
Water can not evaporate without the sun.
Answer:
In harsh winter, usually there's less food, therefore, rabbits will not be able to find enough food and the population of rabbits will decrease.
