Which evidence is provided by fossil record

Biology
1 answer:
GalinKa [24]2 years ago

The fossil record

This supports Darwin's theory of evolution, which states that simple life forms gradually evolved into more complex ones. Evidence for early forms of life comes from fossils. By studying fossils, scientists can learn how much (or how little) organisms have changed as life developed on Earth.There are gaps in the fossil record because many early forms of life were soft-bodied, which means that they have left few traces behind. What traces there were may have been destroyed by geological activity. This is why scientists cannot be certain about how life began.

Fossils provide a snap shot of the past and allow us to study how much or how little organisms have changed as life developed on Earth.

Moraines are made of till. They form when a glacier stays in one place for a long time and deposits a pile of till, then it retreats and leaves a moraine.

When 15n-labeled aspartate is fed to animals, the 15n-label rapidly appears in many amino acids. What reactions are occurring to
malfutka [58]

Aspartate + a- keto acid >> Oxaloacetate + a amino acid

This reaction is occur because the a- keto acid in the equation can come from any amino acid, the 15 N from aspartate is rapidly transferred to other amino acids.

15N is symbol use as the isotope of nitrogen with mass number 15. comprises of 0.4 % of stable nitrogen found, so the relative abundance of each in amino acid is simply a reflection of how much is found in nature in general.

This isotopes is enrichment of the labelled amino acids was determined following a previously developed procedure comprising by determination of the spectral purity of the selected natural abundance amino acids.

topjm [15]

Evolution's patterns manifest as nested similarities. nesting occurs between molecular sequences of evolutionary related organisms and between the different taxa arranged in a phylogenetic tree. True

Phylogenetic tree is a branching diagram that shows the evolutionary relationships between various species.

Nesting behavior is an urge in the pregnant animal to prepare a home for the upcoming generation which occurs due to increase in the amount of estradiol to protect them from predators and environment.

Nesting behavior is also taken consideration to understand the phylogenetic similarities between various species.
