When a gummy bear shrinks, is that considered hypertonic or hypotonic?
raketka [301]

Answer:

Hypertonic

Explanation:

In hyper-tonic solutions, the cell will shrink and crenate. The mass and volume of a gummy bear that is placed in a salt solution will decrease due to the effect of osmosis. When placed in water, a hypo-tonic solution, the gummy bear will expand in size and volume due to the water entering it.

Two short-haired guinea pigs are mated several times. Out of 100 offspring, 25 of them have long hair. What are the probable gen
Alekssandra [29.7K]

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.

Being able to respond to change (irritability) is one of the necessary life functions. Which body system is mostly responsible f
Ede4ka [16]

Answer:

The correct answer is : nervous system.

Explanation:

Irritability is one of the key aspect life which is deal with being able to response or change according to the stimuli that is occur and disturbs the homeostasis of the body which is maintaining the body environment for living.

Nervous system is deal with the irritability by sensing the stimuli in which change occur it can be physical stimuli such as temperature, light, or sound or chemical stimuli such as pH, ions, amount of required chemical or biological stimuli such microbes in body. All these stimuli are sense b the sensory neurons and then send these signals to brain or spinal cord in order t act and respond accordingly to maintain homeostasis.

Thus, the correct answer is : nervous sytem.
