A family takes its summer vacation at a beach resort. Six-year-old Timmy spends the entire morning in a swimming pool. When his

mother finally gets him out and dries him off, she remarks that his fingers and toes are "wrinkled up just like a prune." Prunes start their lives as plums. They get their characteristic wrinkles by dehydration. Sitting for hours in water is anything except dehydration. How can you solve this mystery? Use the Internet to investigate the wrinkling of a prune and the wrinkling of the skin when it is immersed in water. Be sure to relate your discussion of this topic to the process of osmosis.

Answer: Water diffuses into the skin via sweat ducts which alters the electrolyte balance. electrolytes can be salts like sodium and potassium. This alters the stability of neurons causing blood vessels to constrict therefore decreasing the amount of fluid in the fingers which would normally give the skin tension. The decrease causes wrinkles.

Explanation: I had that answer before and it was really hard to understand it, I hope this helps you. Best Of Luck!

Punnett Squares are used by geneticists to determine the likely genotypes of the offspring of two parents.
PilotLPTM [1.2K]
That's correct - it's a square where on one axis, the paternal allele (allele = one of the possible forms of the same gene), and on another the maternal allele is listed. Often, it's also indicated whether an allele is recessive or dominant.

Then, in the table that results, all the possible "combinations" of allele between the paternal and maternal party are created. If you count how often a certain combination appears, it indicates the likelihood of that combination.
See the picture (though it is directly from Wikipedia, please note). The likelihood of BB is 25%, of Bb is 50%, and of bb 25%.

Thermochemical conversion is a process which is used to produce solid, gaseous, and liquid fuels.

<h3>What are the processes of biomass production in generation of gas</h3>

Biomass is converted into energy through various processes such as Direct combustion means burning to produce heat. Thermochemical conversion is a process which is used to produce solid, gaseous, and liquid fuels while on the other hand, Chemical conversion is a process to produce liquid fuels.

So we can conclude that thermochemical conversion is a process which is used to produce solid, gaseous, and liquid fuels.

1 Populations that show uniform dispersion typically show the following characteristics EXCEPT:
professor190 [17]

1. Answer: C

Explanation: Species that are inclined to clumping means they are more likely to cooperate in tasking such as gathering food. However, evenly distributed population means there is competition between individuals hence the need to their own space and territory from the other individual.

2. Answer: B

Explanation: While the clumped up populations may be inclined to cooperate in tasks such as food gathering, such distribution results to increases intraspecies competition especially during scarcity. This is because the individuals are close together – which is also advantageous during mating season.

3. Answer: A

Explanation: Type 3 survivorship curve is characterized by a high mortality rate early in the life of the species which gradually progresses to a low mortality rate for the individuals that survive the early stages of life. These species, therefore, bear a lot of offspring most of which will not make to adulthood.

4. Answer: B

Explanation: If the death rate of a population is higher than the birth+ immigration rate, then the population must be decreasing. This can be demonstrated by a growth curve of a population such as that of bacteria. The population starts decreasing due to increased competition for reduced resources after reaching carrying capacity  - depicted by the stationary phase.
