Answer/Explanation:
Let's say the allele for short hair is S and the allele for long hair is s. Since long hair is recessive, an individual would need to have two copies of that allele to show the genotype (h0m0zygous - ss). That means they must inherit one from each parent.
A guinea pig with short hair could be h0m0zygous (SS) or heterozygous (Ss)
Since a short haired male and a short haired female produced some long haired offspring, they must each have a copy of the long haired allele (s). Otherwise there is no way their offspring could inherit two copies of the s allele. The offspring must have got one s allele from each parent.
Therefore, the parents must both be heter0zygous (Ss)
The particles of the chair are strongly held together.
The chair is lower in energy than the surrounding environment.
The particles of the chair are free to move and form their most stable positions.
The chair is made of particles that are relatively far apart and spread out to a maximum to form the chair shape.
b. ecosystem—biome—community—population—individual
c. individual—population—community—ecosystem—biome
d. ecosystem—individual—population—biome—community
Answer: c. individual—population—community—ecosystem—biome
Explanation:
Biosphere is a part of earth which includes the living beings like plants and animals interact with the other important spheres of the earth like atmosphere, lithosphere, and hydrosphere to lead a healthy life.
c. individual—population—community—ecosystem—biome is the correct sequence that lists the levels of the biosphere from smallest to the largest.
The individual represent a single organism of any species, the population includes individuals of a single species, the community includes members of two or more species living together, the ecosystem involves one or more biotic communities which interact with their non-living physical environment.
Answer: Chitin
Explanation:
Carbohydrates can be defined as the class of bio molecules which includes sugar, cellulose, chitin and many forms.
Chitin is the major constituent of the exoskeleton. It is made of polysaccharide. It is a type of exoskeleton which is is found in arthopods which provides support to the shrimp.
This polysaccharide is chitin.
The specialized carbohydrate used for structure in shrimp is chitin. Chitin is a long-chain polymer of N-acetylglucosamine, which is a derivative of glucose.
Chitin provides strength and flexibility to the exoskeleton, allowing the shrimp to move and grow while still being protected and is also found in the exoskeletons of other arthropods, such as crabs and lobsters. It is also found in the cell walls of some fungi and algae.
Chitin is a very strong material. It is even stronger than steel, pound for pound. However, it is also very lightweight. This makes it an ideal material for the exoskeletons of shrimp and other arthropods.
The exoskeleton of a shrimp is made up of several layers of chitin. The outermost layer is the hardest layer. It is called the epicuticle. The epicuticle is made up of a waxy substance that helps to protect the shrimp from water loss and from predators.
