Scientists found a layer of rock with several different fossils in it, as shown in the image. Based on the model, which of these fossils are the oldest and which are the newest? Explain your answer.

LOOK AT THE PICTURE!

Answers

Answer:

Fossils generally helps in relative dating of rocks.

The Trilobites are considered the oldest in this rock sequence when we apply the principle of superposition of strata.

The principle states that "in an undeformed/undisturbed sequence of rock, the oldest is always at the bottom while the youngest is on top" .

This principle therefore explains why the Trilobites at the base are considered the oldest.

Flowering plants grow from seeds
The embryo inside the seed starts to grow into a seedling. Roots grow down to anchor the plant in the ground. Roots also take up water and nutrients and store food. A shoot grows skywards and develops into a stem that carries water and nutrients from the roots to the rest of the plant

Answers

Answer:

See below

Explanation:

The structure of the cell is very much linked with the functions of the cell. The cardiac muscle is made of the myocardium which serves the body by providing the blood, nutrients and oxygen. The cardiac muscles appear striped when seen under a microscope.

The skin consists of the tissues and cells which are close enough to create a boundary that does not allow the entry of materials and pathogens inside the body.

Hence, the function and the morphology of the cells are somewhere related to each other.

A seagull flew 145 meters to the east at a constant velocity. It flew that distance in
10.0 seconds. What was its velocity?
What’s the answer ?

Answers

Given parameters:

Displacement of the seagull  = 145m to the east

Time taken to cover the distance = 10s

Unknown:

Velocity  = ?

Solution:

Velocity is one of the physical quantities. It is the speed in a specific direction. Hence, velocity is a vector quantity having both magnitude and direction.

  So, mathematically;

           Velocity = [tex]\frac{Displacement }{Time taken}[/tex]  

         Velocity  = [tex]\frac{145}{10}[/tex]   = 14.5m/s due east

The velocity of the seagull is 14.5m/s due east

Answer:

v=d/t=v=145/10.0=14.5m per second

Answer:

b) Fossils supported Darwin's ideas about

common ancestry and the relationship of

living species to fossil species.

Explanation:

How did fossils contribute to Darwin's ideas about changes in species over time?

Fossil remains have been found in rocks of all ages. Fossils of the simplest organisms are found in the oldest rocks, and fossils of more complex organisms in the newest rocks. This supports Darwin's theory of evolution, which states that simple life forms gradually evolved into more complex ones.

Fossils supported Darwin's ideas aboutcommon ancestry and the relationship ofliving species to fossil species.

Common ancestry allows Darwin to infer what happened in the lineage leading to modern mammals. The fact that present day birds and reptiles have sutures but no live birth is evidence that sutures were present in the lineage leading to modern mammals before live birth evolved.

Fossils showed that all species are the result

Fossils showed that all species are the resultof gradual changes over time.

Fossils. Fossils provide solid evidence that organisms from the past are not the same as those found today; fossils show a progression of evolution. Scientists determine the age of fossils and categorize them all over the world to determine when the organisms lived relative to each other.

Fossils explained how species develop

Homologous features

Homologous features If two or more species share a unique physical feature, such as a complex bone structure or a body plan, they may all have inherited this feature from a common ancestor. Physical features shared due to evolutionary history (a common ancestor) are said to be homologous.different traits.

Fossils showed how humans had affected the

Fossils showed how humans had affected thetraits of organisms for thousands of years.

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 type of fault is formed when divergent plate move​

Answers

A divergent boundary or divergent plate boundary (also known as a constructive boundary or an extensional boundary) is a linear feature that exists between two tectonic plates that are moving away from each other. Divergent boundaries within continents initially produce rifts, which eventually become rift valleys. Most active divergent plate boundaries occur between oceanic plates and exist as mid-oceanic ridges.[1][2] Divergent boundaries also form volcanic islands, which occur when the plates move apart to produce gaps that molten lava rises to fill.
