Answer:
Answer number 2
Explanation:
So in Geology, Precipitation of rock layers took place over the last hundreds of millions of years...During that process many living organisms have died and are precipitated with the rock layers... Let me explain with an example.
Dinasours went extinct Million years ago while the Dodo bird went extinct a couple of hundred years ago
Would you expect to find Dinasour fossils in newer rock layers or the dodo? lets's say 200m deep? Dodo for sure, Dinasour fossils are waay too old to be found at such shallow deeps that's why fossils in newer layer of rocks are absolutely younger than fossils found at deeper layers
One hot summer day Thomas left a glass of full of water outside when he went back to get it the next day half of the water was gone what type of interaction with the Earth system was this
A.Lithosphere-Biosphere
B.Hydrosphere-Atmosphere
Answer:
B
Explanation:
Hydrosphere-AtmosphereB. Hydrosphere-Atmosphere
The hydrosphere comprises the totality of Earth's water. The atmosphere comprises the totality of Earth's air. The liquid water in the glass that was left outside evaporated, turning into gaseous water vapor that escaped the glass. The water as a liquid in the glass and as a vapor as a gas are both part of the hydrosphere. But once some of the liquid water became gaseous water vapor, that water became part of the Earth's atmosphere.

Have a great day!
The only statement which describes how jellyfish have a different adaptation to moving in the ocean than sharks and dolphins is:
Jellyfish fill the top part of their body with water and squeeze the water out to move.
What is adaptation?This is the ability of an organism to successfully adapt and survive in a particular environment.
Within the context of this medium, jellyfish bodies are:
Tansparent They have long tentaclesSo therefore, jellyfish fill the top part of their body with water and squeeze the water out to move.

What happens when red blood cells decreases in the blood?
Answer:
Having a low level of red blood cells can diminish the ability of the blood to transport oxygen, which can cause the heart to come under strain as it works to get enough oxygen to the tissue. Anemia can happen with lower red blood cell count or when red blood cells dont contain enough hemoglobin.

What type of carbon-based molecule is the first to be broken down by the body's cells to provide a source of energy?
Answer: Glucose
Explanation:
The carbon based molecule which is broken by the cells of the body is glucose it is a carbohydrate that is obtained from food we consume it is stored in the form of glycogen. When the energy requirement of the body increases then glucose monomers are released from the glycogen chain so that glucose monomers can participate in the energy generation process in the mitochondria of the cell. The chemical energy so produced is ATP (adenosine triphosphate).

The

The ozone in the

The
has the highest temperature of any layer in Earth’s atmosphere.
Answer:
Mesosphere
Stratosphere
Trophosphere and Mesosphere
Stratosphere
Thermosphere
Explanation:
The Stratosphere
This extends upwards from the tropopause to about 50 km. It contains much of the ozone in the atmosphere. The increase in temperature with height occurs because of absorption of ultraviolet (UV) radiation from the sun by this ozone.
Troposphere
Earth’s troposphere extends from Earth’s surface to, on average, about 12 kilometers (7.5 miles) in height.
Mesosphere
Located between about 50 and 80 kilometers (31 and 50 miles) above Earth’s surface, the mesosphere gets progressively colder with altitude. In fact, the top of this layer is the coldest place found within the Earth system, with an average temperature of about minus 85 degrees Celsius (minus 120 degrees Fahrenheit).
Thermosphere
Located between about 80 and 700 kilometers (50 and 440 miles) above Earth’s surface is the thermosphere, whose lowest part contains the ionosphere. In this layer, temperatures increase with altitude due to the very low density of molecules found here.

How does gas exchange occur in plants?
Plants obtain the gases they need through their leaves. They require oxygen for respiration and carbon dioxide for photosynthesis.
Explanation:
The gases diffuse between the cells spaces of the leaf through pores, which are normally on the underside of the leaf - stomata. From these spaces they will diffuse into the cells that require them.
The red imported fire ant is an invasive species that has affected many native species in North America. Scientists wanted to see the effect of the fire ants on the survival of a certain kind of native bird. They treated nests of the bird with a chemical that kills the ants. They treated a different percentage of bird nests in different areas. In some areas, only 25% of the bird nests were treated with the chemical. In other areas, 100% of the bird nests were treated with the chemical.
The graph below shows the percent of birds surviving compared to the percentage of bird nests treated with the ant-killing chemical.
What conclusion about the effects of fire ants on the birds is best supported by the graph?
A.
The birds are more likely to survive when there are many fire ants, so the ants are likely outcompeting the birds for resources.
B.
The birds are more likely to survive when there are many fire ants, so the ants are likely providing resources for the birds.
C.
The birds are less likely to survive when there are many fire ants, so the ants are likely taking over the niche of the birds.
D.
The birds are less likely to survive when there are many fire ants, so the ants are likely predators of the birds.

Describe how the relative surface temperature and the relative luminosity of Aldebaran would change if it collapses and becomes a white dwarf like Procyon B
Answer:
Greatly affect the luminous intensity.
Explanation:
The relative surface temperature and the relative luminosity of Aldebaran will greatly decreases if it becomes Procyon B because more surface area of a star increases the luminous intensity of that star. The size of Aldebaran is 30.7 million km whereas the size of Procyon B has 8585 km which very much lower than the Aldebaran so there is a great difference in the magnitude of luminosity between Aldebaran and Procyon B. So we can conclude that the decrease in the surface area of a star will greatly affect its luminous intensity.

Which of the following is a true statement?
A. Disruptions in an ecosystem are normal and natural changes.
B. Disruptions in an ecosystem are caused by both human activity and environmental disturbances.
C. Ecosystems are complex, interactive systems that include both biotic and abiotic components of the environment. D. All of these are true statements.
Answer:
All the statements are true and the correct option is;
D. All of these are true
Explanation:
Ecosystems change over time. ... Sudden disruptions such as volcanoes, floods, or fires can affect which species will thrive in an environment. Other disruptions are caused by human activities
An ecosystem ecosystem is an area where a community living (biotic) and non living (abiotic) things such as plants, animals, other organisms, landscape, natural sources and weather interact to create an apparently sustainable system
An ecosystem undergoes several changes over time due to environmental disturbance which results in the variation of the ecosystem's structure and change rate due to the natural disturbance and/or human activity
Therefore all the statements are true.
