The correct answer is option C
The best way to classify the organism when they appear similar and found in the same area must be observed by studying the genotype of the organism.
Sometimes it is not possible to observe the change in the organism by looking physically( phenotype) so, in this case we must use the gel electrophoresis to compare the DNA pattern.
Answer:
They all include an exchange of gases with the atmosphere.
The carbon, oxygen, and nitrogen cycles are biogeochemical cycles meaning the chemicals spend a portion during the cycle in living things ( bio) and a portion in the nonliving environment
Answer:
D. 3:1
Explanation:
Gregor Mendel, in one of his numerous studies, performed a cross between purebred dominant (TT) pea plants and purebred recessive (tt) pea plants. All the offsprings of this cross appeared heterozygous tall (Tt) in the F1 generation.
However, when he self-crossed the F1 generation i.e. Tt × Tt, Mendel obtained a phenotypic ratio of 3 tall plants (dominant traits) : 1 short plant (recessive). This showed that the masked gene (recessive) was still present.
Particles or molecules that are too big to fit through regular pores in the cell membrane, or have to big an electric charge, against the current of passive transport ( lower to higher ).
