Secondary structures are stabilized by which type of interaction?
Brrunno [24]
This pertains to the structure of proteins. Secondary structures are stabilized by the presence of hydrogen bonds. The common types of secondary structures of proteins are the alpha helix and the beta sheets, each performing different functions. 

Primary structure of protein is the peptide molecule comprised of peptide bonds. Once these peptide grows long enough, it will either be arranged into alpha helices or beta sheets stabilized by hydrogen bonds and this is the secondary structure. Once there is protein folding involved in the secondary structure of protein, then the folded protein is called the tertiary structure (or a protein subunit). When protein subunits come together to perform a specific function, then that is the quaternary structure.

Attached is a figure concerning the protein structures.

Write three facts you discovered about patterns of heredity and human genetics
lubasha [3.4K]
If two parents have dark hair, the child will most likely have dark hair.
If one has light and the other dark, the child has a 75% chance of having dark hair or a dark-dominated mix because the gene for dark hair is dominant.
If two parents have light hair, the child will most likely have light hair.

Of course, it gets a lot more complicated than this, the genes of the child's grandparents and great grandparents could be carried by the parents as well. So if the parents have dark hair but they each have a parent with light hair, the light hair gene will be carried by them and could be passed on to the child. That's how it is with genetic disorders, such as Systic Fibrosis or Sickle Cell Anemia.

In your own words, explain what natural selection is?
Katyanochek1 [597]

Answer:

Natural selection is the process of which forms of life having traits that better enable them to adapt to specific environmental pressures, such as predators, changes in climate, or even competition for food or mates. As the species will tend to survive and reproduce in greater numbers than others of their kind, thus ensuring the perpetuation of those favorable traits in succeeding generations.
