Fittoniya [83]

Answer:

1. genotypically

2. phenotypically

Explanation:

The genotype of an individual represents the total number and types of genes and the alleles of each gene present in the nuclei of its cells. In humans, the presence of two copies of X chromosomes makes an individual female. However, some individuals have two copies of X chromosomes but have masculine features. Similarly, some individuals have one X and one Y chromosomes in their cells. These individuals are genotypically males. But they have some feminine features. This makes them phenotypically female. Phenotype is the morphological expression of genotype.

Nataly_w [17]


They are composed of long chains of amino acids.

The building blocks of protein are amino acids. Amino acids are organic molecules made up an alpha (center) carbon atom which is linked to an amino group, a carboxyl group, a hydrogen atom and  a variable component  known as a side chain.

Amino acids are joined to each other by peptide bonds  to form either a short chain called an oligopeptide or  a long chain called a polypeptide.  These chains are what forms the protein.

Independent Variable: Temperature
Dependent Variable: Animal Metabolism

Animal metabolism will only be affected if the temperature of the room changes. Therefore animal metabolism is dependent on temperature.

9:
Independent Variable: Rainfall
Dependent Variable: Thickness of growth rings

The thickness of the tree's growth rings are determined by the amount of rainfall. Therefore the thickness of growth rings are dependent on rainfall.
