Snow falling on glacier would be an example of atmosphere-cryosphere interaction.
        
             
        
        
        
Answer:Dehydration
Explanation:
 Dark urine is usually indicative of dehydration; but there could be more reasons responsible for it. Ideally, when you eat or drink something, it goes through your digestive tract, circulatory system and then to your kidney. Kidneys are where everything is filtered and urine is produced. Urine contains the harmful toxins which need to be eliminated from the body. Darker urine is more concentrated. It is indicative of the fact that unnecessary toxins and wastes are circulating in your body which could mess with your health. This, again, depends on how much fluids you drink throughout the day. But there could be many other reasons responsible for the same.
 
        
             
        
        
        
Answer:
a. amygdala
Explanation:
According to my research on studies conducted by various neurologists, I can say that based on the information provided within the question the part of the brain that was most likely under investigation in this study was the amygdala. This can be said because the amygdala is the part of the brain that is responsible for emotions, survival instincts (which dictates fear levels), and memory.

The correct option is A ie the process whereby non-sister chromatids exchange genetic material
- Between prophase I and metaphase I, a process known as crossing over occurs in which two homologous non-sister chromatids join up and exchange various pieces of genetic material to create two recombinant chromosome sister chromatids.
- When genetic material is switched between two chromosomes, this process is known as crossing over.
- It is in charge of causing genetic variation among members of a species.
- Only the reproductive cells known as gametes undergo this process.
- The steps involved in crossing over are as follows:
1) Synapsis.
2) Chromosome duplication
3) Crossing over.
4) Terminalizataion.
