Answer:
The structure of proteins is complex and unique, and only specific molecules can interact with their surface features. The natural shape of each protein is termed the native state. When proteins are exposed to heat, acid, or alcohol, their shape is disrupted and they become nonfunctional or denatured.
Explanation:
Physical agents such as heat, and chemicals such as alcohol and acids cause protein denaturation, that is, a loss of the spatial conformation and structure of the proteins and with this their functionality. Depending on the intensity of the event there may be total loss of function. The three-dimensional structure of a protein is basic for the protein to perform its function correctly.
The Van der Waal’s forces are the forces, which are formed by the attraction of two opposite charged bodies. This charge exists due to the formation of the dipoles in the molecules or atom. The dipoles formed due to the movement of the electron in the atoms. The strength of the dipole or Van der Waal attraction depends on the size of the atoms or the molecule. As the size increases, the strength of the Van der Waal force increases. The positive and the negative regions are shown in the attached picture.
Answer:
Small hydrophobic molecules and gases like oxygen and carbon dioxide cross membranes rapidly. Small polar molecules, such as water and ethanol, can also pass through membranes, but they do so more slowly.
hope this helps :D
Explanation:
Answer:
A. Population growth increases
Explanation:
When the growth is no longer being limited by a limiting factor, the population increases because the factor that limits the growth is gone.
Answer:
Brachydactyly and Huntington are phenotypic diseases that develop when a person has one or two dominant alleles for these traits.
John's father has the Huntington disease, but not brachydactyly so his genotype is Hh/bb.
John's mother is a healthy women with brachydactyly, so her's genotype is probably hh/BB or hh/Bb.
