<u>Answer:</u>

Principle of Superposition  causes the youngest layers to be on top.

<u>Explanation:</u>

  • Principle of Superposition states that when two or more waves having similar intensity and characteristics, intersect each other at the same point, some displacements occur as a result.
  • This displacement is equal to the sum of the displacements of both the waves.
  • The stratification of sedimentary rocks is based on the same principle. Thus, when two layers of soil come in contact, the younger soil layer deposit above the older one.

The first strong evidence for colinearity between a gene and its polypeptide product resulted from studies by:
ozzi

Answer:

The correct answer is option c, that is, Charles Yanofsky.

Explanation:

An American geneticist, Charles Yanofsky, worked as a faculty at Stanford University took part in the development of one gene-one enzyme hypothesis, and found attenuation, that is, a riboswitch mechanism.  

In the mechanism, the messenger RNA modifies its shape in response to a small molecule, and therefore, changes its binding capability for the regulatory region of an operon and a gene. His studies suggested that genes and proteins are co-linear. If the section of the intron in the gene gets mutated, then the protein generated by the protein also gets mutated.

Trypanosome infections evade attacks by host immune systems through which of the following mechanisms? A. insertion of its DNA i
lapo4ka [179]

Answer:

<h2>Through production of news cell-surface proteins with a different molecular structure by each new generation. Letter B</h2>

Explanation:

The life cycle of theses paratises extracellular alternate between the salivary glands of the insect transmitter and the blood of the mammal. During the set prior to the entry into the host, the metacylic parasites express a dense over formed by the Variant Surface of Glycoprotein, after entering to the mammal host they transform  into a morphology that stays in the bloodstream.

<em>The parasites have to manipulate hosts cells in order to avoid the production of antimicrobial molecules and to benefit from growth factor production.</em>

<em>Intracellular protozoa have a remarkable adaptive capacity as they are able to resist killing by remodelling the phagosomal compartments where they reside and by interfering with the signalling pathway that leads to cellular activation. </em>
