Answer:

secondary structure

Explanation:

Alpha helices and beta sheets are two main structural forms in secondary structure of proteins. This structures are formed spontaneously. The next step of protein structure formation is folding into tertiary three-dimensional form.

In diseases such as CJD and kuru, protein prion is changed in structure. It is not known how degeneration of priones protein structure occurs, but it can lead to neurodegenerative diseases which can even be fatal.

Priones are also known as proteinaceous infectious particles.

Which conditions are common to all three of the following: genetic drift, the founder principle, and the bottleneck effect? a. i
Tcecarenko [31]

Explanation:

Common to genetic drift, the founder principle, and the bottleneck effect:

b. in small populations and result in a decrease in genetic diversity and/or an increase in the occurrence of specific genetic traits

c. when a small group of organisms only reproduce with each other to create a larger population of organisms

d. when the majority of a population is killed off and there are only a few remaining organisms left to rebuild the population

Further Explanation:

During the process of cell division, spontaneous changes within the genome can arise, called mutations. These are errors occur when copies of the DNA within the cell are made; mutations may range from small changes called single nucleotide polymorphisms, to large scale deletions, and additions which span multiple genes.

These mutations form variants which become stable within a population, leading to the formation of separate, genetically distinct populations called species.

  • mutations accumulate in a population over time, altering the frequency of alleles or different forms of a gene- this is called genetic drift.
  • In the founder effect, the separation of a group from a larger group can decrease genetic diversity, this can create a genetically distinct population
  • In the bottleneck effect, a population die off or barrier to reproduction increases the genetic drift in the population

Trees use narrow tubes to transport water upward. Which property of water allows the water to rise in these narrow tubes?
cluponka [151]

Answer:

C. Cohesion of molecules

Explanation:

Cohesion is the interaction of molecules of the same substance together. By the force of cohesion if two drops of water come together they form one. Water has high rates of cohesion due to hydrogen bonds.  

This phenomenon also called surface tension and is what allows small insects to stand on water.

Cohesion along with adhesion of water to the walls of the narrow tube generate what is called capillarity. This allows liquids to ascend inside the narrow tubes. As long as the cohesion is less than the adhesion, the liquid will rise until both forces are equal.
