Respuesta:

B. pastoreo excesivo de animales de granja

Porque son lugares secos.

Explicación:  

Las políticas e infraestructuras que promueven la agricultura en las tierras de pastoreo que no pueden mantener sistemas viables de cultivo, contribuyen a la desertificación. La mayoría de las áreas de tierras secas (el 65%) son tierras de pastoreo que son más adecuadas para el pastoreo sostenible que para el cultivo.

What role does the MutL protein play in DNA repair? (5 POINTS) It performs a proofreading function, similar to DNA polymerase, a
Zinaida [17]

Answer:

It recognizes and binds to a pair of "mismatched" nucleotides, preventing their translation.

Explanation:

Mut L protein is involved in mismatch DNA repair. MutL protein is complexed with MutS protein and the MutL-MutS complex recognizes all the mismatched base pairs present in the newly formed DNA strand. The complex can not recognize the "C-C" pairs. MutH protein joins the complex.

The MutH protein also has a site-specific endonuclease activity and cleaves the unmethylated DNA strand towards the 5' end of the guanine base in the GATC sequence to mark the strand for DNA repair. In this way, MutL protein, along with MutS and MutH proteins mark the mismatched DNA bases for repair so that they are not translated into a faulty protein.

Are insects intermediate host or definitive host? Are there any symptoms of gongylonemiasis? If the insects are the definitive h
Lemur [1.5K]

Answer:

They are intermediate hosts.

Explanation:

Disease-transmitting insects are called vectors.

The life cycle of disease-causing pathogens is closely linked to the biology of the insect that carries it.

 The symptoms of gongylonemiasis include  hemorrhagic inflammation  at the site the pathogen invades,  followed by  granulomatous tissue development that  produces nodules in the invaded organ.

Some diseases transmitted by insects occur in both humans and other mammals because our differences in anatomy and physiology are not very different.

It is unlikely that clinical symptoms will occur in humans if the insect were the definitive host, because our biology is quite different from their biology, and the pathogen would be adapted to fulfill its entire life cycle in their body.
