The answer would be B. Cats.
Cats are the most advanced organisms between the options thus have the greatest amount of cell specialization.
A Only one variable changed
Chromatography is a simple technique in principle, it remains the most important method for the separation of mixtures into its components. It is quite versatile for it can be used to separate mixtures of solids.
Explanation:
- The two elements of chromatography are the stationary phase and the mobile phase. There are many choices of stationary phases, some being alumina, silica, and even paper. The mobile phase, in liquid chromatography, can also vary. It is often either a solvent or a mixture of solvents and is often referred to as the eluant.
- A careful choice of eluting solvent helps to make the separation more successful. The mixture is placed on the stationary phase. The eluant passes over the mixture and continues to pass through the stationary phase carrying along the components of the mixture.
- Chromatography is used in industrial processes to purify chemicals, test for trace amounts of substances, separate chiral compounds and test products for quality control. Chromatography is the physical process by which complex mixtures are separated or analyzed.
- Chromatography is based on the principle where molecules in mixture applied onto the surface or into the solid, and fluid stationary phase (stable phase) is separating from each other while moving with the aid of a mobile phase
The correct options are as follows:
1. D.
<span>A clade refers to a group of organisms that are made up of evolutionary descendants that originated from a common ancestor. A clade that will survive a series of catastrophic events must be one that is made up of distantly related and diverse species. This is because, those species will have different type of adaptability capacity and will be able to adapt in different ways to the catastrophic events. Due to the differences in their ability to adapt, some of the specie will survive the catastrophic events even if others are wipe out.
2. B.
The mass extinction of one specie usually creates space for another new specie to survive. The new specie that survive the old one may possess the ability to adapt to the event that wipe out the former set of living organisms and thus, the new specie will be able to occupy and reproduce in their new space. Mass extinction is said to occur when the whole population of living organism living in an ecosystem are wipe out as a result of unfavorable conditions.
3. B.
Convergent evolution refers to the independent evolution of similar features in species that arise from different lineages. The species involved usually evolve these traits as a result of having to adapt to similar environments. Convergent evolution usually result in evolution of analogous structures, that is, structures that have similar forms or functions but which are not present in the last common ancestors of the species.
4. C.
In evolution, gradualism refers to theory that states that evolution occurs slowly and gradually, thus, large changes in evolution are actually product of small changes that occur over a long period of time. The theory of gradualism was originally proposed by James Hutton in 1795.
5. C.
Mass extinction refers to the wiping out of a a large number of species within a very short time. Mass extinction can occur as a result of severe unfavorable conditions that all the species in an ecosystem can not adapt to. An instance of this is a drastic decrease in global temperature after several massive volcanic eruptions.</span>
El Ministerio de Medio Ambiente (MINAM) gestiona esto, lo gestiona a través del comité nacional sobre el clima.
El cambio climático en Perú es vulnerable y necesita altas adaptaciones. Hay una gran contribución al calentamiento global por el derretimiento de sus glaciares ubicados en los picos andinos.
La pesca y la agricultura en las regiones costeras de bajo nivel son propensas a la elevación de alta mar que puede destruir las infraestructuras económicas y disponibles presentes.
Esta institución de los gobiernos está haciendo un esfuerzo frenético para reducir esta vulnerabilidad, asegurando una reducción en la emisión de gases de efecto invernadero.
Además, el país está adoptando caminos con bajas emisiones de carbono en un intento por conservar la reserva forestal de carbono, con una mayor reducción de las emisiones de la combustión de combustible y otros sectores industriales.
Answer:
This is being managed by the ministry of environment(MINAM).It manages this through the national committee on climate.
The climate change in Peru is vulnerable and needs high adaptations.There is high contribution to global warming from the melting of its glaciers located on at the Andean peaks.
Fishery and agriculture at low-levels coastal regions are prone to high sea rise which may destroy the economic and available infrastructures present.
This institution of the governments is making frantic effort to reduces this vulnerability, by ensuring reduction in the green house gas emission.
Besides the country is embracing low carbon paths in an attempt to conserve the forest carbon reserve,with further reduction in emission from fuel combustion and other industrial sectors.
