Which statement correctly describes amphipathic (or amphiphilic) helices and sheets?Helices are typically hydrophilic on one sur
Sloan [31]

Answer:

The correct answer is the last statement.

Explanation:

Amphipathic refers to a substance that comprises both hydrophobic and hydrophilic surfaces. Thus, the given first three statements are incorrect. The amphipathic helices are witnessed on the proteins surfaces in which the hydrophilic region associates with the aqueous phase and the hydrophobic regions associate with the hydrophobic component of the protein.  

Both the amphipathic sheets and helices exhibit primarily the hydrophobic or hydrophilic residues on one face. Thus, the correct answer is the last statement.

Hepatocyte growth factor aff ects satellite cell activation and diff erentiation in regenerating skeletal muscle
vichka [17]

Hepatocyte growth factor (HGF) is the only known growth factor that activates quiescent satellite cells in skeletal muscle.

Hepatocyte growth factor regulates cell growth, cell motility, and morphogenesis by activating a tyrosine kinase signaling cascade after binding to the proto-oncogenic c-Met receptor. Hepatocyte growth factor is secreted by mesenchymal cells and acts as a multi-functional cytokine on cells of mainly epithelial origin.

HGF, produced by some cancer cells, stimulates c-Met, through activation of the autocrine signaling system. Hepatocyte growth factor (HGF) is a paracrine hormone that plays an important role in epithelial-mesenchymal transition. HGF secreted by mesenchymal cells affects many properties of epithelial cells, such as proliferation, motility, and morphology.

Can you complete this concept map that reviews some key ideas about macro evolution
Inessa [10]
Macroevolution can cause significant changes in the frequencies of alleles, that can ultimately result in speciation (forming of new species).
Various large-scale events like climate change and continental drift can greatly influence the distribution of species and adaptive radiation of different groups that can fill vacant ecological niches.
The changes in gene regulation and genetic mutations can also contribute to macroevolution by producing novel traits and adaptations.

Map pling Sickle-cell anemia is a disease that affects the type of hemoglobin (Hb) a person makes in his or her red blood cells.
topjm [15]

Answer:

The correct answer is codominance.

Explanation:

It is given in the question that the genotype of Martin is HbS/HbS, and is exhibiting sickle cell anemia with unusual hemoglobin. On the other hand, the genotype of Cindy is HbA/HbA, which shows that she possesses normal hemoglobin. Both of them have a child, Mary who as usual is exhibiting genotype HbS/HbA.  

This shows that Mary has acquired both the alleles for sickle cell anemia from her parents, and thus, is demonstrating both unusual and normal form of hemoglobin. Sickle cell is a condition that does not demonstrate the phenomenon of complete dominance, as it is a codominant trait.  

A phenomenon in which the features of both the alleles are expressed in the phenotype is termed as codominance. Hence, Mary is demonstrating a codominance pattern.
