Suggest two ways that reflex reactions help maintain homoeostasis in the human body.

Answers

Answer 1
Two ways that suggest that reflex reactions help maintain homeostasis in the human body are
1. By maintaining breathing - Maintenance of breathing is also a reflex reaction that helps maintain homeostasis on human body.
2. By recognizing discomfort level - In this case the reflex action can give message to the brain that the movement is causing discomfort and the body can move back to original position.
Answer 2

Final answer:

Reflex reactions help maintain homeostasis in the human body by regulating functions such as heart rate and pupil size through the autonomic nervous system. The sympathetic and parasympathetic systems create a balance by providing opposing actions that respond to different environmental stimuli, essential for health and stability.

Explanation:

How Reflex Reactions Maintain Homeostasis

Homeostasis is the stable state of internal conditions in the human body. Reflex reactions play a critical role in this process. For instance, the autonomic nervous system manages involuntary functions such as heart rate and pupil dilation through the sympathetic and parasympathetic systems. These systems often act in opposition to create a balance, or homeostatic state.

Regulation of heart rate: The parasympathetic system reduces heart rate by slowing it down during rest, while the sympathetic system can increase heart rate during stress or activity, helping to provide more oxygen to tissues when needed.

Regulation of pupil size: Similarly, the sympathetic system dilates the pupils to let in more light and enhance vision under certain conditions, whereas the parasympathetic system constricts the pupils in bright light to protect the retina and maintain optimal vision.

These actions ensure that critical bodily functions are maintained within a narrow range of operation, which is essential for overall health and stability of the body's internal environment.

How many passengers can fit into the cessna 406 hold?

Answers

2 crew, 12 passengers

Although the capacity of the Cessna 406 is not provided, similar Cessna models show that passenger capacity depends on the aircraft's weight limits and the weight of fuel and equipment. For instance, a Cessna 172 can hold up to 625 pounds of passengers and a Cessna 182 Skylane up to 769 pounds.

By examining similar aircraft, we can gather that passenger capacity is dependent on the aircraft's maximum gross takeoff weight and its fuel capacity. For example, the four-place Cessna 172 has a maximum gross takeoff weight of 2300 pounds, with an allowance of 625 pounds for passengers and equipment after considering the plane's weight and fuel, averaging 156 pounds per person. And similarly, the Cessna 182 Skylane can accommodate pilot, passengers, and accessories weighing up to 769 pounds. Thus, while the question about the Cessna 406 is not explicitly answered, we can infer that to calculate passenger capacity, one must consider the specific aircraft's weight and balance limits, and reduce the maximum gross takeoff weight by the aircraft's empty weight and fuel weight.

A person uses a spoon to eat a certain food. each spoonful tastes slightly different from the one before it. the food is most likely _____. a compound a heterogeneous mixture an element a homogeneous mixture

Answers

Heterogenous Mixture is the correct answer ! Hope it helps

Answer: Option (b) is the correct answer.

Explanation:

A mixture that consists of two or more components in a solution which are distributed in non-uniform composition is known as a heterogeneous mixture.

For example, mud in water is a heterogeneous mixture.

Components of a mixture never combine chemically with each other.

A compound is a substance that contains two or more elements which are chemically combined to each other. For example, [tex]CaCl_{2}[/tex] is a compound.

An element is a substance that contains same atoms. For example, element copper will have only atoms of copper.

A mixture in which solute particles completely dissolve in the solvent throughout the solution is known as a homogeneous mixture.

For example, sugar in water is a homogeneous mixture.

Thus, we can conclude that a person uses a spoon to eat a certain food. each spoonful tastes slightly different from the one before it. the food is most likely a heterogeneous mixture.

Answers

Final answer:

The correct answer is 'biomes'. Biomes are large geographic areas on Earth that share the same climate. They are broader in scope than habitats, communities, or ecosystems.

Explanation:

The Earth can be divided into large geographic regions known as biomes. These are areas that have the same climate, which simply refers to the average atmospheric conditions experienced in a specific region over an extended period of time. Examples of biomes include deserts, tropical rainforests, and savannahs. The other options in your question, communities, ecosystems, and habitats, all relate to biomes, but they are more specific or broad in their definitions. For example, a habitat is where a specific animal lives, an ecosystem includes all the living and non-living components in a specific area, and a community includes all the populations of different species that live in the same area and interact with each other.

The answer is: 

b. Succession ultimately leads to climax communities, which are stable and sustainable. 

Correct answer: B). Succession ultimately leads to climax communities, which are stable and sustainable

Ecological succession is the process, which involves the change in the species structure over a time. The ecological community starts with the few animals and plants and it develops into a complex community until it becomes stable as a climax community.

A Climax community is a type of ecological community in which all the species of animals and plants are in a stable state and exist in a balanced state with each other and with the environment. It is a final stage of succession, which is long-lasting and stable until disturbed by the human intervention.

Explanation:

Options for the question are

nervous system

excretory system

circulatory system

Solution

Blood is  part of circulatory system and as it move through various organs it exchanges the gases i.e give oxygen to the cell and take carbon dioxide from them. After taking CO2, the  blood becomes impure and hence it passes through the kidney before going to the heart. Kidney is part of excretory system which removes carbon dioxide from blood and thus purifies it.  

Hence, correct answer is excretory system  and circulatory system

During _____ both the contents of the nucleus and the cytoplasm are divided. during _____ both the contents of the nucleus and the cytoplasm are divided. g2 mitosis s g1 the mitotic phase

Answers

Interphase is the phase of the cell cycle in which a typical cell spends most of its life. During this phase, the cell copies its DNA in preparation for mitosis.[1] Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, reads its DNA, and conducts other "normal" cell functions.[1] The majority of eukaryotic cells spend most of their time in interphase. This phase was formerly called the resting phase. However, interphase does not describe a cell that is merely resting; rather, the cell is living, and preparing for later cell division, so the name was changed. A common misconception is that interphase is the first stage of mitosis. However, since mitosis is the division of the nucleus, prophase is actually the first stage
Final answer:

During mitosis, both the nucleus and cytoplasm are divided. This is part of the mitotic phase, which also includes cytokinesis, the division of the cytoplasm into two daughter cells. This follows interphase, which is when the cell prepares for division by growing and duplicating its DNA.

Explanation:

During mitosis, both the contents of the nucleus and the cytoplasm are divided. Mitosis is the first part of the mitotic phase and consists of five stages. During this process, the duplicated chromosomes are aligned, separated, and moved to opposite poles of the cell.

Following mitosis is cytokinesis, the second part of the mitotic phase. Cytokinesis refers to the division of the cytoplasm and cell body into two new identical daughter cells. The division of the nucleus and cytoplasm ensures that both daughter cells receive a full set of chromosomes and enough cytoplasmic machinery to operate.

Overall, interphase, including phases G₁, S, and G₂, and the mitotic phase (mitosis and cytokinesis) are crucial parts of the cell cycle. It's important to note that interphase is characterized by cell growth and DNA duplication, preparing the cell for division during the mitotic phase.
