Answers
Answer:
In this picture the ground is now completely covered in vegetation and trees are growing back all along the road and sides of the picture. Then there’s little flowers and grass and bushed all over the place. In the other pictures the ground was bare, with the second and third pictures having bushes and other little vegetation starting to grow. Changes in the Biotic Factors: There are now larger trees, there is grass, flowers, small bushes, and other small vegetation growing. Changes in Abiotic Factors: The ground is no longer dust and ash, The dead trunks and branches are covered in vegetation for the most part and are decomposing.

How does your model show what happened to the circled rock material as a result of plate motion?
Answers
Answer:
Once exposed, they are weathered, both physically (by mechanical breaking of the rock) and chemically (by weathering of the minerals), and the weathering products — mostly small rock and mineral fragments — are eroded, transported, and then deposited as sediments. Therefore, the model should show signs of deterioration and subduction.
Explanation:
I'm not sure if this is on a quiz or test, but this is what I would put down. No need to mark me brainliest, thanks anyway! :)

why is earth's crust necessary for any life to take hold on our planet
Answers
Answer:
I think is this
Explanation:
The crust is a thin but important zone where dry, hot rock from the deep Earth reacts with the water and oxygen of the surface, making new kinds of minerals and rocks. It's also where plate-tectonic activity mixes and scrambles these new rocks and injects them with chemically active fluids.

A graph showing the energy of the reactants and products of cellular respiration is shown here. Which description accurately compares the products and reactants of cellular respiration in terms of energy level?
Answers
Answer:
Water and carbon dioxide are products and have a lower energy level than the reactants.
In cellular respiration, water and carbon dioxide are products. According to the graph, the products have a lower energy level than their reactant counterparts.
The minimum energy is required by the element to reach the Threshold is called activation energy.
The description in the question is not given, Hence the question is incomplete.
According to the diagrams, the reactant is converted into the products when the Gibbs free energy is less than zero.
The products are modified form the reactants and the possible product in this reaction is might be water and carbon dioxide.

Answer:
a. Gregory Mendel
Explanation:
Gregory Mendel is the father of genetics
Gregory Mendel is widely considered to be the father of genetics
Option A is correct
How do we explain?Gregor Mendel was an Austrian monk and botanist who is considered to be the father of genetics. He conducted experiments on pea plants and was able to formulate the laws of inheritance, which are the basic principles of genetics.
Mendel's work was not widely recognized until the early 20th century, but it has since had a profound impact on our understanding of genetics. His work laid the foundation for the study of genetics and has helped to advance our understanding of how traits are passed down from parents to offspring.
Therefore, Option A is correct

Explain how the availability of resources in the environment is linked to exponential growth of a species
Answers
Answer: Exponential growth occurs when resources in the environment are abundantly available to a species.
Explanation: When a food source amount drops, so does the survival rate of the predator that eats that specific food source. When a food source grows too abundantly at too fast a rate, predators increase in numbers.

One of the concerns about rising CO2 levels ocean water is the negative effect on certain types of marine life, such as oysters and clams. Does your experiment show a negative effect? Explain your answer.
Answers
Answer:
see below :)
Explanation:
For many years sea life such as oysters and clams have been acostumed to the temperature of the water. Rising levels of CO2 will cause more heat in water temperatures. This would make the shells of the oysters and clams 'wear away'.
Answer:
yeah the person under me is right
Explanation:
Ocean acidification is a consequence of the excess carbon dioxide in the atmosphere from fossil fuels. When the ocean absorbs the CO2, the water becomes more acidic. Shelled animals like zooplankton, corals, clams, mussels and oysters cannot grow their shells in the acidic water.

The noble gases in group 18 were some of the last natural elements to be discovered. Why do you think this is so?
Answers
Answer:
because they were extremely un-reactive. Being inert, they were difficult to isolate via chemical reactions, thus difficult to distinguish as separate elements
Explanation:
The noble gases of group 18 were the last to be discovered because they are highly unreactive or inert.
Noble gases refer to elements in group 18. These elements are renowned for being inert.
As a result of their inertness and because they are all gases, they are sometimes called "inert gases".
This chemical inertness made it difficult to discover these elements until lately. Many natural elements were discovered because they participate in chemical reactions. Hence, inert gases became the last natural elements to be discovered.

During a large thunderstorm, you hear and feel the thunder. Draw a representation of the sound wave produced. Your model should account for the energy and patterns of the wave.
Answers
Answer:
Sound waves are longitudinal waves that travel through a medium like air or water. When we think about sound, we often think about how loud it is (amplitude, or intensity) and its pitch (frequency).
Explanation:
This is why we hear and feel them!
Sound waves are longitudinal waves that travel through a medium like air or water. When we think about sound, we often think about how loud it is (amplitude, or intensity) and its pitch (frequency).
What is Sound waves?A sound wave is the pattern of disruption brought on by the movement of energy moving through a medium as it propagates away from the source of the sound (such as air, water, or any other liquid or solid matter).
Pressure waves are produced when an object vibrates, such as a ringing phone, and these waves are known as sound waves. The surrounding medium's particles are disturbed by the pressure wave, and those particles disturb the particles next to them, and so on.
Like ocean waves, the disturbance's pattern causes outward movement in all directions. Usually in all directions and with decreased intensity as it gets further away from the source, the wave transmits the sound energy through the medium.
Therefore, Sound waves are longitudinal waves that travel through a medium like air or water. When we think about sound, we often think about how loud it is (amplitude, or intensity) and its pitch (frequency).
