In deducing the evolutionary relationships among dogs, do you think it would be better to use a sequence that is neutral or one
sweet-ann [11.9K]

Answer:

a neutral marker

Explanation:

A gene polymorphism can be defined as the existence of two or more variants of the same gene (i.e., alleles). A polymorphism may be a difference of one nucleotide base in DNA (single nucleotide polymorphisms, SNPs) or indels (i.e., insertions and deletions). A gene under selection will have many polymorphisms in its sequence which may lead to convergence and disproportionate divergence among sequences, and thereby will be uninformative to trace the evolutionary history among individuals within a species, population, etc. Conversely, neutral molecular markers exhibit fewer nucleotide differences, it is for that reason that they are commonly used to determine genetic population structure among individuals.

IRINA_888 [86]

Carbon dioxide and water are components of air help to trap infrared energy.

The atmosphere then acts as a blanket, keeping the heat of the planet from escaping back to the area. This result is thanks to bound gases within the atmosphere that are superb at gripping and re-radiating the warmth energy before it's lost to the area.

These gases, referred to as "greenhouse gases", embrace greenhouse emission, water vapor, and paraffin.

Explain why catalase activity is considered a virulence factor? in terms of bacteria?
elena55 [62]

Answer:

Catalase allows the decomposition of the hydrogen peroxide.

Explanation:

The virulence factor is any molecule secreted by bacteria that allow them to colonize in host.

The enzyme catalase allows the splitting of hydrogen peroxide in water and oxygen. This process prevent them from  ROS that is reactive oxygen species. Thus, catalase activity is considered as a virulence factor.
