When a person breathes in, what happens to the diaphragm and to the cage?

Answers

Answer 1

Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarges. This contraction creates a vacuum, which pulls air into the lungs. Upon exhalation, the diaphragm relaxes and returns to its domelike shape, and air is forced out of the lungs.

Answer:

OA

Explanation:

Chemical energy refers to the energy that is released with reactions involving chemicals. Cellular respiration takes glucose(a five carbon sugar) and breaks it down using glycolysis, then makes ATP(adenisine-triphosphate)(an essential chemical to the energy of life) using the krebs cycle and the electron transport train. This is all to get a surplus ATP, which is a useable CHEMICAL ENERGY source. This energy can be diverted to any system in the body, including the muscular system. Then, the muscles are used MECHANICALLY(look at the types of muscle levers in anatomy) to acheive work, thanks to the CHEMICAL ENERGY produced in cellular respiration. Thus, the answer in OA.

Causes of background extinction; Changes in the environment, such as climate change or geological events, can cause slow, long-term changes that make certain species less adapted to their environment.

The introduction of new predators or changes in predator-prey relationships can also lead to the extinction of some species.

Genetic factors can play a role in the extinction of species, particularly in small populations where genetic diversity is low.

Causes of mass extinction; Mass extinctions can be caused by catastrophic events, such as asteroid impacts, massive volcanic eruptions, or global climate change.

Rapid changes in the environment, such as sudden climate change or sea level change, can cause species to become extinct.

Changes in the ocean, such as ocean acidification or anoxia, can lead to the extinction of marine species.

Human activities such as overhunting, habitat destruction, pollution, and introduction of invasive species can also contribute to mass extinction events.

How does a cell's external environment affect the movement of water across the cell membrane?

Answers

Answer:

water molecules move according to the energy from where they are to where they're going.

Explanation:

The external environment of the cell significantly affects the movement of water across the cell membrane when a cell is placed in three types of solution.

What is a cell membrane?

A cell membrane may be defined as a type of biological membrane that significantly separates and protects the interior environment of all cells with respect to the outside environment. It is semi-permeable in nature which regulates the transport of materials entering and exiting the cell.

If a cell is placed in a hypertonic solution, water will migrate out of the cell, and the cell will shrink. In an isotonic environment, there is no net water movement, so there is no change in the size of the cell. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.

Therefore, the external environment of the cell significantly affects the movement of water across the cell membrane when a cell is placed in three types of solution.

Please can you explain what this paragraph is trying to say. Also what does it mean in the sentence 'the difference in charge across the battery provides push for current' and what is the difference in charge.



Here's paragraph I need to have a simple definition of:


A high waterfall is also like a large voltage. It will transfer a lot of energy to the water (charge), making the river flow very fast (a large current) the difference in height makes the river flow. In a circuit , the difference in charge across battery provides push for the current.

Answers

Answer:

This paragraph is drawing an analogy between a high waterfall and an electric circuit to explain the concept of voltage and current.

It is saying that a high waterfall has a lot of potential energy that can transfer to the water and cause it to flow very fast, which is similar to how a large voltage in an electric circuit can create a large current. The difference in height of the waterfall causes the water to flow, just as the difference in charge across a battery provides the push or force for the current to flow in a circuit.

In an electric circuit, voltage is the measure of the electric potential difference between two points, and it is measured in volts. Current is the flow of electric charge through the circuit, and it is measured in amperes or amps. The difference in charge across the battery refers to the potential difference or voltage between the positive and negative terminals of the battery, which creates an electric field and provides the force or push for the current to flow through the circuit.

Brainlist Please

This paragraph is using an analogy between a high waterfall and a large voltage to explain the concept of voltage and current in a circuit.

The paragraph starts by comparing a high waterfall to a large voltage. Just as a high waterfall transfers a significant amount of energy to the water, a large voltage in a circuit transfers a significant amount of energy to the flow of electric charge.

The energy transfer in the waterfall causes the river to flow very fast, which is likened to a large current in a circuit.

The "difference in height" in the waterfall analogy refers to the variation in elevation between different points in the waterfall. This difference in height creates a force that propels the water downstream, causing the river to flow. Similarly, in a circuit, the "difference in charge" refers to the disparity in electric charge between two points in the circuit.

This difference in charge, also known as voltage, provides the "push" or driving force for the flow of electric current. It is this voltage difference across the battery that causes the electric current to move through the circuit.

In summary, the paragraph illustrates that just as a high waterfall with a significant difference in height creates a fast-flowing river, the difference in charge (voltage) across a battery in a circuit provides the driving force (push) for the flow of electric current.

The cell membrane, also called the plasma membrane, is a double layer of lipids and proteins that envelops a cell and divides the cytoplasm (the contents of the cell) from the external environment.

Only particular molecules are allowed to enter and exit because it is selectively permeable. The quantity of some chemicals entering or leaving the cell can also be regulated.

Cells are surrounded by cell membranes, which are incredibly thin and only partially permeable, which keep the inside of the cell isolated from the outside world.

Some compounds can pass through the fluid lipid bilayer whereas others cannot since it is a fluid barrier.Selective permeability refers to the ability of the cell membrane to regulate what can enter and leave the cell.The cell membrane is crucial for preserving the integrity of the cell and controlling communication and interactions between cells.

Answers

Embryonated chicken eggs represents an in vivo method for cultivating viruses. (option c)

To cultivate viruses in a living system, an in vivo method is used. Among the options provided, embryonated chicken eggs are the most commonly used method for culturing viruses in a living organism.

HeLa cells: HeLa cells (a) are human cancer cells commonly used in laboratory research, but they are not a living organism suitable for virus cultivation.

Pure bacterial cell cultures: Bacterial cell cultures (b) are often used to study bacteriophages, which are viruses that infect bacteria. However, this method involves culturing viruses in bacterial hosts and does not involve a living organism.

Embryonated chicken eggs: Embryonated chicken eggs (c) are a widely used method for virus cultivation. In this method, viruses are injected into the developing embryo, which provides an environment for viral replication. The embryos provide a controlled and nutrient-rich environment for the viruses to grow and propagate.

Lung cell culture: Lung cell culture (d) involves growing lung cells in a laboratory setting. While this method can be used to study certain viruses, it is an in vitro (outside a living organism) method rather than an in vivo method.

In conclusion, the in vivo method for cultivating viruses among the options provided is embryonated chicken eggs. This method provides a living system in which viruses can replicate and propagate. (option c)

Answers

The statement that surface fires may actually benefit some plant species and some game animals is false. Surface fires can be beneficial for the environment, but can also be destructive. Thus, it is important to be aware of the potential implications of surface fires and to use them responsibly.

Surface fires are a type of wildfire that occur on the ground surface of a forest and can be caused by lightning strikes or human activities. They are often characterized by their low intensity, relatively quick burning of fuels, and the possibility of being controlled with relative ease. While surface fires can be destructive, they can also be beneficial to the environment.

Surface fires can help control pathogens and insects, as they burn away dead organic material that can accumulate and lead to insect infestations. The heat from surface fires can also reduce the spread of disease-causing microorganisms in the forest. Additionally, surface fires can help control weed growth, which can be beneficial for other plants.

Surface fires, however, can also be destructive. Wildlife and mature trees are relatively unharmed by surface fires, but younger vegetation can be severely damaged or destroyed. Additionally, frequent surface fires can increase the chances of crown fires, which are more intense and can spread quickly and cause more destruction.
