Answer:
Explanation:
Why are layers of rocks related to each other?
Layering, or bedding, is the most obvious feature of sedimentary rocks. ... This Law of Superposition is fundamental to the interpretation of Earth history, because at any one location it indicates the relative ages of rock layers and the fossils in them. Layered rocks form when particles settle from water or air.
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.

Explanation:
1) Eubacteria cells lack a nucleus, and are therefore________
Viewing eubacteria requires a microscope,because they all single celled organisms.another word for single celled is_______
Answer:
The correct answer is - prokaryotic and unicellular.
Explanation:
Eubacteria is known as the true bacteria and belongs to the prokaryotic type of cells which is characterized by no double-membrane organelles or the nucleus. All the genetic material is present in the cytoplasm itself.
These bacteria are single-cell microscopic organisms as they are very minute to see by the naked eyes and required a microscope to study. Another word for the single-cell organisms is unicellular.
The diagram below shows two kinds of cells.

How do animal behaviors lead to successful reproduction and growth of their young?
Answer: Their actions help the young survive in the wild
Explanation: Examples of behaviors that affect the probability of animal reproduction could include nest building to protect young from cold, herding of animals to protect young from predators, and vocalization of animals and colorful plumage to attract mates for breeding.r
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.

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

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.
