Explain how the complexity and diversity of living things has changed over time. Use evidence from the text, boxes of fossils and rock strata diagram and scientific reasoning to support your response.

this is the reading:
The Precambrian: In Maryland the rocks found from the Precambrian period are metamorphic and igneous. No fossils have been positively identified from these rocks thus far.

The Paleozoic: The Paleozoic era in Maryland was a time of changing sea levels. The sedimentary rocks contain abundant marine fossils, indicating the presence of warm, shallow seas. A period of uplift and mountain building occurs later in the area and was followed by a time of erosion and subsidence (the gradual sinking of land). During times of subsidence, the seas returned and flooded the lands. These cycles of uplift and flooding led to alternating deposition of non-marine and marine sediments. Brachiopods and bryozoans were abundant in the sea, while horsetail rushes and scale trees thrived in the warm, humid, Late Paleozoic climate on land.

The Mesozoic: Plate movement pulled apart the supercontinent of Pangea. The area that is now Maryland filled with sediment creating a coastal region where fossils of plants and dinosaur footprints can be found. Late in the Mesozoic (Cretaceous), seas advanced and retreated across the coastal plain numerous times, providing habitats that ranged from land organisms to deep sea organisms. Fossils of plants and dinosaurs are common in the terrestrial deposits, while marine fossils include mollusks and brachiopods.

The Cenozoic: During the Early Cenozoic in Maryland, sea level fluctuated, leaving marine deposits in coastal areas. The climate cooled later in the Cenozoic, vast ice sheets advanced and retreated across North America, and sea levels dropped as the glaciers expanded. The cooler temperatures encouraged the growth of new types of plants, while mastodons and other cold-adapted animals roamed the state. During warmer climate periods (interglacial), sea levels again rose to cover the eastern part of the state. Fossils of marine clams, oysters, and snails are abundant in the rocks formed during these interglacial episodes.

Answer 1

Living organisms are known to often evolve. Due to human evolution, humans have develop more complex structures and also grow to larger in sizes.

How has the complexity of organisms changed?

New research in evolution theory has shown that though  the use of relaxing selection pressure, it has been found that its  streamline genomes, therefore making the complexity of an organism to increase.

Diversity in living things has also changed a lot, with a lot of extinction taking place in the Earth’s. The extinction event has lead to a decrease in diversity. The diversity when viewed  locally do fluctuate.

This decrease in diversity is said to be, due to human activities, such as land use rotations, pollution, etc.

Complexity in terms of individual eukaryotic cell has shown to have little changes in about two billion years, and that makes it  complex.

Diversity has been shown to often increases and decreases over time.

Why isn't there a huge deep sea trench next to California like there is next to South America?

Answers

Answer:

Deep-sea trenches generally lie seaward of and parallel to adjacent island arcs or mountain ranges of the continental margins. They are closely associated with and found in subduction zones—that is, locations where a lithospheric plate bearing oceanic crust slides down into the upper mantle under the force of gravity.

Explanation:

"The result is a topographic depression where the oceanic plate comes in contact with the overriding plate, which may be either oceanic or continental. If the overriding plate is oceanic, an island arc develops. The trench forms an arc in plan view, and islands with explosive volcanoes develop on the overriding plate. If the overriding plate is continental, a marginal trench forms where the topographic depression appears to follow the outline of the continental margin. Explosive volcanoes are found there too"

1. What was one cause of the development of

Explanation:

If the weather changes and the partial pressure of water is reduced to 1.7 kPa, what is the new dew-point temperature

Answers

The complete question was not included to give context to the question, so we will present the formula for solving for the dew point. Given relative humidity, the dew point can be calculated with this formula;

Td = T - ((100 - RH)/5where Td= dew point temperature in degree celsiusT= Observable temperatureRH= Relative humidity

It is important to note that the measurement of the dew point is connected to humidity. When the humidity is high the dew point is also expected to go higher.

A reduction in partial pressure will also make the dew point reduce.

This is because of the wider gap that is created between the ambient temperature and dew point.
