Answer:
internal fertilization, development of an embryo within the female body, and the developing embryo deriving nourishment from its mother
Explanation:
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)
B. their digestive structures.

B.They evolved after the seeded flowering plants.
C.They evolved after the seedless vascular plants.
D.They evolved before the seedless nonvascular plants.
The statement that best explains the evolution of gymnosperm plants is that they evolved after the seedless vascular plants.
Gymnosperms are classes of plants that do not produce fruits but rather bear seeds structures called cones.
Gymnosperms and angiosperms both belong to the class of plants called higher plants because they have mechanisms for conducting and transporting water and nutrients.
Gymnosperms are believed to evolve before angiosperms or flowering plants but after seedless vascular plants called pteridophytes.
Therefore, the statement that best explains the evolution of gymnosperm plants is that they evolved after the seedless vascular plants.
