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.
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.

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.

Although the living reptiles birds are most closely related to are crocodilians (archosaurs), when it comes to their relation to dinosaurs, birds evolved from theropod dinosaurs. These theropods share over 100 traits with modern birds.

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.

The diagram shows a model of a section of double-stranded DNA. The straight lines and dotted lines represent chemical bonds between the
components of the molecule.
During DNA replication, which chemical bonds break apart? Select all that apply.
The DNA has two double strands, and they have different chemical bonds, so during the DNA replication, the hydrogen bonds that are present between the two strands break to separate the DNA.
What role does DNA replication play?DNA replication is the process of making two DNAs from a single DNA, and here the hydrogen bonds that are present between the bases, such as thymine and adenine, which have two hydrogen bonds, and guanine and cytosine, which have three hydrogen bonds, break. The purpose of DNA replication is to make a copy of the genetic content of the cell so that it can be passed to other cells.
Hence, the DNA has two double strands, and they have different chemical bonds, so during the DNA replication, the hydrogen bonds that are present between the two strands break to separate the DNA.

Think of another science topic you studied earlier. How might considering scale be useful when investigating that topic? How is that similar to and different from how the crosscutting concept of Scale is useful in this unit?
Scale can be extremely important to consider when applying the conclusions of an investigation to a larger group.
Scale is defined as a series of measurements in a given ratio, in order to compare two objects or groups. Some examples include:
Scale modelsScale populationsIn the case of scale models, one example may be creating a 1:100 scale model of a building. What this means is that the model created will be one hundred times smaller than the original.
The idea of scale is very important to consider when performing experiments. For example, if we were to take a sample of 10 people and test for a specific bacteria, which gives us a result of 1 in 10 (or 10%) of the people that test positive for the bacteria, it would seem as though it is a very small number of people. However, if we take scale into consideration we can apply this 10% to the global population, which will result in hundreds of millions of people who will test positive for the bacteria.
Scale is important to consider when performing any experiment or drawing conclusions because it offers a method to calculate and make an educated assumption as to the impact of the results on a population that would otherwise be impossible to test.

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.

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.
