Based on morphological and molecular data, researchers hypothesize that the split between dugongs and proboscideans likely occur

red between 48 and 34 million years ago. Explain how molecular data from fossils and living organisms would support the existence of an evolutionary relationship between dugongs and proboscideans.

Answer:

Both molecular and morphological comparisons among dugongs and proboscideans species should be conducted

Explanation:

From a molecular biology point of view, it is possible to compare the sequences of dugongs and proboscideans and thus observe the homology level between genes of interest, it in order to establish evolutionary relationships among species. Moroever, by mass spectrometry (MS), it is possible to compare proteins in fossils >1 million years, these comparisons may shed light on the evolutionary origin of one group

If natural selection has no foresight, how can it explain features that seem to prepare organisms for future events? for example
Nezavi [6.7K]

The genes in a population give forth the genetic variability across a population (genotypes). In addition, occasional mutations of these genes in a population increase this genetic variability. Hovever, natural selection only favours reproduction of individuals with genes that are favourable in the environment/habitat. Therefore, natural selection has no foresight but is rather pegged on being an ‘opportunistic’ process.

marshall27 [118]

Answer:

The cow uses all but stores ten percent of what they eat.

Explanation:

For example, a plant produces 100 percent energy. The plant needs to use the energy for survival.

When a cow eats the plant, it only gains 10 percent of the energy.

Then, say a wolf eats the cow.

The wolf only gets 1 percent of the energy that is produced by the plant.

mihalych1998 [28]
<span>John could make some simple changes to his breakfast to increase his fiber intake. Instead of orange juice, he could drink juice with added fiber such as V8 juice or fiber added grape juice. Instead of corn flakes, he could eat a high fiber cereal such as Grape Nuts. Instead of white toast, he could eat a slice of high fiber whole wheat bread. He can make some simple substitutions that will really impact his diet and his health.</span>
