Which of the following best explains the importance of studying the ocean carbon cycle?
a. The oceans have a significant impact on the levels of atmospheric gases.
b. It is a new field of ocean science.
c. The ocean releases one quarter of the carbon dioxide in the atmosphere.
d. All of the above
Answer:
d. All of the above
Explanation:
All of the given choices are reasons to study the ocean carbon cycle. The ocean occupies about 70% of the earth surface area and it plays important roles in carbon cycling.
The ocean acts as reservoir for carbon in many different ways especially due to the dissolution of this gas in it. It also releases a significant amount of carbon dioxide to the atmosphere due to the plethora of life within it. The field is also relatively new and more works must be done to understand this cycle.Answer:

how does the data that Scientists collect get used with climate models? scientists collect data then developed and use models to maken predictions about future climate conditions.
Answer:
To make these predictions, meteorologists use weather data and forecast models to determine current and future atmospheric conditions. Because weather takes place hour by hour, forecast models use current atmospheric and oceanic conditions to predict future weather.

The chemical formulas are aluminum bromide (AlBr₃), magnesium bromide (MgBr₂), sodium sulfide (Na₂S), and the chemical compound formula of the sodium nitride is Na₃N.
What is the significance of the chemical formulas?Chemical formulas are important to identify the chemical composition of the mixture as they provide important information about the types and numbers of atoms present in a molecule or compound and also predict the properties of a substance, such as its melting point and boiling point. This is useful in industries such as manufacturing, agriculture, etc which has significant importance in the field of medicine, as it helps researchers understand how the human body interacts with the drug.
Hence, the chemical formulas are aluminum bromide (AlBr₃), magnesium bromide (MgBr₂), sodium sulfide (Na₂S), and the chemical compound formula of the sodium nitride is Na₃N.

A reflex response to excessive pain or heat is first processed through the brain.
True
False
Answer:
False
Explanation:
The above statement is false
False because reflexes and snap reactions are generally bounced back directly from the spinal cord to save time. An example could be touching something hot because you react and move away instantly rather than your body burning for a second while the brain processes the information.

What are some "topics" to be considered when discussing the California Current
Ecosystem
Answer: Red tide events
Explanation:
Red tide events causing massive fish die-offs, unprecedented sea ice loss, erosion of coastal wetlands, and bleaching of coral reefs not only impact marine ecosystems but also communities, peoples' well-being, local businesses, and more.
These issues impacting ecosystems and people require solutions that consider ecosystems and people. These types of solutions are Ecosystem-Based Management, which considers social, economic, and ecological trade-offs when deciding how to address these issues.

If humans change the function or equilibrium of one of Earth's systems, this will not change
the function or equilibrium of all of Earth's systems.
True
False
Answer:
False.
Explanation:
All of the things found in the Earth system can be categorized into four (4) main categories and these includes;
I. Land: this subsystem forms a sphere which is generally referred to as litosphere.
II. Water: this subsystem forms a sphere which is generally referred to as hydrosphere. It comprises of landforms such as mountains, valleys, plateaus, ridge, rocks, etc.
III. Air: this subsystem forms a sphere which is generally referred to as atmosphere. This sphere comprises of gases such as oxygen, carbon dioxide, nitrogen, etc.
IV. Living organisms: this subsystem forms a sphere which is generally referred to as biosphere. It comprises of all living things such as humans, animals and plants.
If humans change the function or equilibrium of one of Earth's systems, this will significantly change the function or equilibrium of all of Earth's systems. Consequently, these changes result in environmental phenomenon such as volcanoes, earthquakes, tornadoes, wildfire, etc.

Answer:
2920 rodents could be elimated a year by the owl if the population of rodents could continue to survive with this bird around.
Explanation:
2x4 because 1 pellot is 4 preyy
2 pellots is 8 prey
8 prey for 1 day
8 x 365
not leap year so don;t say 356
so 2920

When the Earth's continental crust and ocean crust formed, they were different densities. Why did they differ in density and how did this affect their formation?
A.) The continental crust was thicker and less dense. It rose above sea level, separating land from water.
B.) The continental crust was thicker and more dense. It sunk below sea level, separating land from water.
C.) The continental crust was thinner and less dense. It rose above sea level, separating land from water.
D.) The continental crust was thinner and more dense. It sunk below sea level, separating land from water.
I think it’s B, but I’m not completely sure. Help please!
Answer: A.) The continental crust was thicker and less dense. It rose above sea level, separating land from water.
Explanation:
The Ocean crust is made out of rocks like basalt with a thickness of about four miles. The Continental crust on the other hand is made out of granite and other similar minerals and is between six and 47 miles in thickness which makes it thicker than the Oceanic crust.
With basalt being more dense than granite, the Oceanic crust sank and the Continental crust rose thereby separating land from water.

Answer: A.) The continental crust was thicker and less dense. It rose above sea level, separating land from water.

Many aquatic birds secrete waxy organic substances that repel water. The birds use these substances to coat their feathers. An analysis of these substances would reveal that they are composed mostly of…
•Lipids
•Carbohydrates
•Nucleic Acids
•nucleic Acids
Answer:
The correct answer would be - lipids.
Explanation:
Many aquatic birds secrete a waxy organic substance which coats their feathers and this substance allows their feathers to repel the water which is helpful for their flying even after floating in the water.
An analysis of these substances would tell that these substances are composed of lipids as lipids are the only macromolecules that are hydrophobic which means they try to avoid water and not allow water to pass through them.

Explanation:
True/ False: Substances will diffuse more rapidly through a dense substance. Explain
Answer:
I'd say true
Explanation:
Mass of the molecules diffusing: Heavier molecules move more slowly; therefore, they diffuse more slowly. The reverse is true for lighter molecules. ... Because cells primarily use diffusion to move materials within the cytoplasm, any increase in the cytoplasm's density will inhibit the movement of the materials.
Answer:
False
Explanation:
As the density of a solvent increases, the rate of diffusion decreases. The molecules slow down because they have a more difficult time getting through the denser medium. If the medium is less dense, diffusion increases.

Which of the following explains why meiosis contributes to genetic variations?
A - it increases the ratio of mitosis within an organism
B - It produces offspring that are different from either parent
C - It decreases the rate of mutation occurrence
D - It forms DNA that is resistant to environmental changes
Answer:
A
Explanation:
The reason of why meiosis contributes to genetic variations is because of option A. it increases the ratio of mitosis within an organism.
Why does meiosis contributes to genetic variations?Since the recombination and the non-dependent assortment in meiosis, each gamete comprise the different DNA set. It generated the unique combination of genes that should lead to zygote.
Also, it rises the mitosis ratio within an organism
Hence, the option A is correct.
