Which of the following observations did Mendel make as a result of his experiments with dihybrid crosses?
Vinvika [58]

The correct answer is: B) Different traits are inherited separately.

Mendel’s conclusions as a result of his experiments with dihybrid crosses are known as Mendel’s laws.

• Mendel’s law of Segregation: During the gametes formation (meiosis), alleles are separated so that each gamete carries only one allele for each gene

• Mendel’s law of Independent Assortment: The segregation of alleles of one gene is independent to that of any other gene

Mendel also defined the Principle of Dominance: Recessive alleles will be masked by dominant alleles when are together in heterozygous genotype.

A student made a model of a cell. First, she filled a clear plastic bag with gelatin.
Ksivusya [100]
B) the model does not show that cells can contain smaller structures inside.

This is true because only a rubber ball was added, indicating that only a nucleus or any one organelle is present in a cell. However, the cell contains more than one organelle from the nucleus, mitochondria, Golgi apparatus, smooth and rough endoplasmic reticulum, ribosomes, and more.

Another possible answer would be D since they model does not show the process of cellular respiration where cells undergo this process to create ATP in the mitochondria.
