Answer:The discovery of the "distal-less," or Dll, gene in many different phyla.

Explanation: Appendages of animals are any external attachment or extension of one or two body parts of an organism in order for it to be able to effectively perform its responsibilities.

The morphological and functional changes or evolution of appendages is responsible for the adaptive radiation of tetrapods, arthropods and winged insects. Recent studies tends to show that all animal appendages may be homologous through the discovery of the "distal-less," or Dll, gene in many different phyla.

Which of the following describes the role of cyclic AMP (cAMP) in hormone response? A. cAMP receives messages from mRNA to begin
Advocard [28]

Answer:

D

Explanation:

Hormones are bigger than the cell pores hence cannot pass through the cell membrane to influence biochemical processes. Therefore, hormones (such as glucagon and insulin) bind onto receptors on the cell membrane, then transmembrane proteins, such as the G-protein, change conformation activating the secondary messengers inside of the cell. Cyclic- AMP is a major secondary messenger  significant in activating protein kinases.

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.
