Which statement best describes the total energy as it moves through the water cycle?
Artist 52 [7]

The correct answer is option D

The energy in the form of heat is absorbed by the water to convert itself into vapour during the process of evaporation. This energy is then released in the atmosphere when the water vapor gets converted into clouds during the process of condensation. From the start of the water cycle , the heat energy of the sun gets converted into the kinetic energy to raise the water vapour to certain height. After reaching heights Kinetic energy is converted into potential energy and then it is finally released to atmosphere after condensation. In the entire process the total energy remains constant it is just being converted from one form to another.

Let p = purple flowers and p = white, and t = tall plants and t = dwarf. if the uppercase letters represent the dominant alleles
sesenic [268]

If the uppercase letters represent the dominant alleles, purple flowers and tall are the phenotype of a plant with the genotype Pptt.

A gene can exist in different forms across organisms. These different forms are known as alleles.

The subsequent combination of alleles that an individual possesses for a specific gene is their genotype.  

Examples of  genotype include:

  • Hair colour
  • Height
  • Shoe size
  • Eye colour

The sum of an organism’s observable characteristics is their phenotype. A key difference between phenotype and genotype is that, whilst genotype is inherited from an organism’s parents, the phenotype is not.

Whilst a phenotype is influenced the genotype, genotype does not equal phenotype. The phenotype is influenced by the genotype and factors including:

  • Epigenetic modifications
  • Environmental and lifestyle factors

Observing the phenotype is simple – we take a look at an organism’s outward features and characteristics, and form conclusions about them. Observing the genotype, however, is a little more complex.

Genotyping is the process by which differences in the genotype of an individual are analyzed using biological assays. The data obtained can then be compared against either a second individual’s sequence, or a database of sequences.
