Answer:
fish: blood flows unidirectionally from the two-chambered heart through the gills and then the rest of the body.
mammal: Blood is pumped from veins of the systemic circuit into the right atrium of the heart, then into the right ventricle. Blood then enters the pulmonary circuit, and is oxygenated by the lungs. From the pulmonary circuit, blood re-enters the heart through the left atrium.

Explanation:
The weathering that most likely played the largest role in creating the cliff was when water in the river broke down the rocks into smaller pieces, which is present in Option B.
What is the weathering process?Rock cliffs can be formed by a variety of weathering processes. One common process is erosion caused by the movement of water as seen here as water flows through the mountains. Over time, these agents of erosion can wear away the softer layers of rock, leaving behind the harder layers that form the cliffs. Physical weathering is caused by the action of natural forces such as water, wind, etc. For example, water can flow into cracks in rock and then freeze and expand when the temperature drops, causing the rock to break apart. Wind can also erode rock surfaces over time by carrying small particles of sand and other debris that scrape and wear down the rock.
Hence, here the largest role in creating the cliff was when water in the river broke down the rocks into smaller pieces, which is present in Option B.

,is homeotasis_____is the application of force to move something closer. *
1 point
A. push
B. pull
C. a push and a pull
D. All of the above
Explanation:
push is the application of force to move something closer..
Point, . push ,a push and a pull is the application of force to move something closer.
Option (D) is correct.
When you apply force to move an object, there are generally two ways to do it: pushing or pulling.
1. Pushing: This is when you exert force on an object away from you, causing it to move in the direction of the force. For example, if you push a chair forward, you apply force in the direction away from you, making the chair move forward.
2. Pulling: This is when you exert force on an object towards you, causing it to move in the direction of the force. For instance, if you pull a door towards you, you apply force in the direction towards you, making the door move inwards.
So, the application of force to move something closer can involve either pushing or pulling. Therefore, the correct answer is "All of the above" (D), as both A (push) and B (pull) are correct ways of applying force to move something closer.

What type of fuel does each energy system produce?.
Answer:
carbon?
Explanation:
Energy systems produce ATP, during every process cellular respiration is the major process of the system.
How ATP as fuel produce by each energy system?During cellular respiration, all the metabolic intermediates finally produce ATP, and in glycolysis, the Kreb cycle produces reducing products which finally oxidize in the electron transport chain.
The electron transport chain produces fuel as ATP, it is an enzymatic chain reaction that produces an electromotive force that is responsible for the production of ATP.
ATP is a major fuel for every cellular process which acts as an energy form that is extracted from metabolic intermediates.
Therefore ATP is a major fuel produced by the system.

Which strategy during the planning stages of a group project would most
likely prevent this problem?
It's clear to group members what tasks in a project need to be
completed, but some members are worried they that don't have the
skills necessary to completescertain tasks.
O A. Choose an organizer.
B. Choose roles
C. Identify deadlines.
D. Listen actively
Answer:
B. Choose roles
Explanation:
Choosing roles would be the best choice in order to avoid the problem stated, because certain people can be put to work on a certain section of the project (that they are suited for). That way, no one will feel as if they lack the skills to complete another part of the project.
Choosing an organizer wouldn't help much because they'd only be organizing the project itself, not the parts that people play within it. Identifying deadlines wouldn't help at all. It would cause stress if anything. Lastly, listening carefully also wouldn't help, because listening to so-and-so won't do anything to the problem at hand. You'd just be listening.
hope this helps!
The strategy during the planning stages of a group project that would most likely prevent the problem of some members being worried about not having the necessary skills to complete certain tasks is to choose roles. The correct option is B.
What is group project?A group project is a collaborative effort where a group of people works together to achieve a common goal or complete a task.
By deciding on roles, each group member can be assigned tasks that are best suited to their skills, interests, and experience.
This can help to ensure that everyone in the group is confident in their ability to complete their assigned tasks and that the workload is evenly distributed.
The most effective strategy for avoiding the problem of members being concerned about not having the necessary skills to complete certain tasks is to assign roles during the planning stages of a group project.
Thus, the correct option is B.

How could harm to one resource among the commons listed in part b cause harm in another part of the environment?
Answer:
Take a picture of what the problem is, because your question isn't clear
Explanation:
Not using complete sentences
For example, overfishing can harm fish populations, leading to imbalances in the food chain and harm to other species.
What are commons?The commons, as a concept, refers to shared resources that are available to all members of a community or society. These resources can include things like air, water, land, and wildlife. When harm is caused to one of these resources, it can have a cascading effect on other parts of the environment.
For example, if pollution from a factory contaminates a river, it can harm the fish and other aquatic life that live in the river. This, in turn, can impact the local ecosystem and reduce the biodiversity of the area. The contaminated water may also be used for agriculture, leading to contaminated crops and potentially harming human health.
Similarly, deforestation can lead to soil erosion, which can cause sedimentation in rivers and harm aquatic life. It can also contribute to climate change by reducing the amount of carbon that is absorbed by trees and released back into the atmosphere.
In summary, harm to one resource among the commons can have far-reaching effects on other parts of the environment, highlighting the importance of managing these resources sustainably.

8. Describe: Locate the Sun on the H-R diagram. How will the Sun's luminosity and
temperature change as it ages? How will these changes affect its position on the diagram?
Answer:
It will eventually become less bright and cooler.
Explanation:
Astronomers estimate that the Sun's luminosity will increase by about 6% every billion years. This increase might seem slight, but it will render Earth inhospitable to life in about 1.1 billion years. The planet will be too hot to support life.
The Sun is a weakly variable star, and its actual luminosity therefore fluctuates. The major fluctuation is the eleven-year solar cycle (sunspot cycle) that causes a quasi-periodic variation of about ±0.1%. Other variations over the last 200–300 years are thought to be much smaller than this.

D) deposition and compaction
Answer:Its C
Explanation: i took the test trust me
physical-weathering is likely the cause of the underground cave system.
Rocks, minerals, and soils disintegrate through a process known as physical weathering, sometimes known as mechanical weathering.
Abrasion is the main physical weathering process (the process by which clasts and other particles are reduced in size). Temperature, pressure, frost, root movement, and burrowing animals can all cause physical weathering.
For instance, physical weathering will expose more surface area through the use of cracks, speeding up the pace of deterioration.
