Answer:
B
Explanation:
Mendel discovered that an organism receives two forms of a gene called allele from each parent. This alleles combine to form the genotype of that organism, which in turn determines the phenotype.
Mendel crossed purebreeding plants that produced only tall and short plants respectively. He got an all tall F1 offspring. He then self-crossed the F1 offsprings to get a phenotypic ratio of 3:1 in the F2 offsprings. He discovered that the tall allele was dominant over the short allele for the height gene in pea plants. This is because the tall alleles masked the expression of the short allele in the F1 generation making them all exhibit tall traits.
The F1 are regarded as hybrids or heterozygotes because they were a mixture or combination of two different alleles. This mixture was confirmed in the F2 offsprings that produced 3 tall plants and 1 short plant, showing that the recessive allele was still present but masked in the heterozygotic combination.
Answer: comenzando en el sitio de desarrollo y saliendo del cuerpo? La producción inicial ocurre en los túbulos seminíferos, los espermatozoides maduran en el epidídimo, luego ingresan a los conductos deferentes, luego pasan por el conducto eyaculatorio y salen del cuerpo por la uretra.
wax represents rock. different colors means different types of rock. the squeezing n folding represent rocks being compressed n folded together. heating in pan is rock getting heated. the whole experiment demonstrates how metamorphic rock is formed.
Measure the amount of energy in the phytoplankton and the amount of light entering the aquarium. Then measure the amount of energy in the phytoplankton after exposure to the light and determine the difference.
Explanation:
Phytoplanktons like most of the plants use chlorophyll, sunlight and carbon di-oxide for photosynthesis but it depends on other organisms to consume extra energy as they are unable to gain enough energy from their consumption of light. This differs among the different species of planktons.
It can be observed in an aquarium that a phytoplankton is gaining less energy than the energy they have absorbed by the light and this can be done by measuring the energy before and after the photosynthesis.
