Answer:
High specific heat.
Explanation:
Water is able to maintain the temperature of living organisms because it has highest specific heat. Specific heat is a physical property of matter. If specific heat is high then the matter does not get heated easily but once it is heated it does not cool down easily either. In short we can say that water can easily resist temperature changes because it has very high specific heat. This property plays a great role in maintaining the temperature of a living organism's body because all organisms have water in their body. When heat is generated within the body, it is unable to disrupt internal temperature of the organism's body because the water does not get heated easily as a result of which the temperature of the body does not rise. On the other hand, the internal temperature of the body remains the same with slight decrease in the temperature outside because water does not radiate heat easily either. This is how high specific heat of water helps in maintaining a constant temperature in the body of organisms.

Answer:
Which of the following is an advantage of an in vitro experiment?
Variables and environmental conditions are controlled.
Explanation:
An advantage of in-vitro experiment is that the variables and environmental conditions are controlled because in-vitro experiment is performed outside a living organism with the environment in control
Answer:
Ss (male) × Ss (female)
Explanation:
This question involves a single gene coding for hair length in guinea pigs. Based on the information in this question, the allele for short hair (S) is dominant over the allele for long hair (s). This means that a guinea pig will only be phenotypically long-haired if the genotype is "ss".
According to this question, Two short-haired guinea pigs are mated several times. Out of the 100 offsprings produced by this cross, 25 of them have long hair (recessive). This means that the phenotypic ratio of this cross is 3 short hair : 1 long hair i.e. 100 - 25 = 75 short hair. 75/25 = 3/1 = 3:1
To produce this phenotypic ratio, the parents must both be heterozygous (Ss) for the hair length gene.
