what happens if too much water is reabsorbed into the blood from the material in the large intestine and the problems this can cause.
Answer:
More ADH will be released, which results in water being reabsorbed and small volume of concentrated urine will be produced. If a person has consumed a large volume of water and has not lost much water by sweating, then too much water might be detected in the blood plasma by the hypothalamus.
Explanation:
If too much water is reabsorbed into the blood from the material in the large intestine, it can lead to dehydration.
The large intestine is responsible for absorbing water and electrolytes from the indigestible material that remains after digestion in the small intestine. Under normal circumstances, the amount of water that is reabsorbed is carefully regulated to ensure that the body stays hydrated and that the consistency of the stool is appropriate.
However, if too much water is reabsorbed, it can lead to dehydration, which can cause a variety of symptoms and problems. These may include:
Dry mouth and thirstDark yellow urineDry skinHeadachesFatigueConstipationDizziness or lightheadednessIncreased heart rateDehydration can be caused by a variety of factors, including not drinking enough fluids, sweating excessively, or having diarrhea. It is important to drink enough fluids and replace lost electrolytes to prevent dehydration. In severe cases, dehydration may require medical treatment.

why is heating water changing its volume
Answer:
As heat increases water begins to evaporate. Evaporation begins at 0C and is at full effect at 100C. So by increasing heat you are increasing rate of evaporation and thus more and more water molecules are lost to the gas phase reducing volume of the water.

------------------------⚡ Awesome ⚡------------------------Brown coat color rabbits possess the dominant allele B, and white coat color rabbits possess the recessive allele b. If the frequency of the allele for white coat color is 0.04, what is the frequency of the dominant allele in the population?
Assuming Hardy-Weinberg equilbrium, we have
p + q = 1
where p = frequency of dominant allele and q = frequency of recessive allele. So
p = 1 - q = 1 - 0.04 = 0.96
Consequently we have
• p² = 0.9216 = frequency of hom ozygous domininant genotype
• pq = 0.0768 = frequency of heterozygous genotype
• q² = 0.0016 = frequency of hom ozygous recessive genotype
since
p² + 2pq + q² = 1
