Answer:
Sandstone is younger than the granite rocks
Explanation:
- As the rocks layer found at the bottom are the oldest and closer to the ground surface are the younger. This is due to the law of superimposition and as when looking at the outcrops you will notice pieces of sandstone within the batholith that indicates that the base is formed by granite and is later cemented by sandstone rock
Alanine and Serine
<span>The degradation of amino acid is to transform
the carbon skeleton into metabolic intermediates that can be easily be oxidized
by the citric acid cycle or converted into glucose. Both Alanine and serine
provide substrate for ketone bodies gluconeogenesis. However, metabolism of
alanine yields pyruvate directly by transamination</span>
Answers:
Zooplankton help other populations survive by keeping out other herbivores
Explanation:
This is because a keystone species are species that have large effect on the the habitat and through its effect they help to keep the ecosystem in existence. They make sure that the ecosystem exist. They help populations survive by keeping out herbivores and feeding on the algae. They help drive nutrients cycle and transfer energy from algae to invasive fish.
The evolution of whales was a gradual process in which terrestrial animals have become more and more adapted to an aquatic environment.
Ambulocetus was perhaps the first whale ancestor that live mostly in water. Evidence suggesting this are the sediments where its fossils where recovered. These were most probably an ancient estuary.
This species had large feet but short limbs, perfectly adapted for swimming. The back limbs were longer than the forelimbs suggesting that together with their powerful tail, they were used for propulsion, in a similar fashion to modern river otters.
This species is a perfect example of a transitional fossil that shows how terrestrial animals can evolve into aquatic animals.
