Which is an example of feedback inhibition answers?

Answers

For example, the effect of the thyroid on the hypophysis is negative feedback or feedback inhibition.

Hypophysis produces the hormone TSH to stimulate the thyroid gland to produce its hormones (T3 e T4). To not exceed the quantity of T3 e T4, these hormones will inhibit the hypophysis so that it stops or decreases the release of TSH, thus reducing the stimulation of the thyroid.






How is the Sun's energy passed along in an ecosystem?

Answers

Energy is passed through the ecosystem in the food chain. Sun to plants to Consumers to Decomposers which keeps going through the food chain, which is the energy

Sun is the primary source of energy in ecosystem where the producers all rely over the sun. The sun's energy is passes from the producers to decomposers in the form of a food chain.

What is ecosystem ?

The living and non living constituents all combine together to form a circle relying on each other.

The living constituents are the living beings along with plants and non living are the abiotic factors such as water, precipitation, temperature and wind.

Sun's energy is passed from the producers that are plants along with the consumers that are herbivores that rely on plants for the purpose of food.

The carnivores depend on herbivores for their nutrition. These biotic and abiotic factors together form dependence and rely on each other making a food chain.

The balance out in nature is made to be stable by not populating any of the living beings along with the abiotic factors' disturbance to be avoided in any manner.

Therefore, the dependency is shown in the form of a food chain.

compare and contrast two of the cycles of matter

Answers

The two cycles of the matter are the carbon and nitrogen cycle. Both of them are biogeochemical cycles, it means that the chemicals spend a portion of the cycle in living things and non-living things. They are also common in that they both recycle nutrients that are essential to all organisms. 

They are different in the manner that they cycle. Nitrogen is huge, 78% of the air around us is nitrogen. It cannot be used by plants or animals. Once the nitrogen is used by the plant and make its way to the animal, it can be released to decomposition. 

Carbon has no requirement in processing by bacteria prior to plants and animals being able to use. Plants take carbon dioxide and make it sugar, animals eat the sugar. Some of it is released carbon dioxide that we exhale.

Final answer:

The carbon and nitrogen cycles are essential for life, involving the transfer of carbon and nitrogen through biological and geological systems. They share similarities like cycling essential elements but differ in processes and pathways, such as photosynthesis in the carbon cycle and nitrogen fixation in the nitrogen cycle.

Explanation:

Comparing and contrasting two cycles of matter, such as the carbon cycle and the nitrogen cycle, highlights how matter is transferred within and between different biological and geological systems. Both cycles are critical for sustaining life on Earth, and involve various physical processes, chemical reactions, and biochemical processes.

The carbon cycle involves the movement of carbon among the biosphere, geosphere, hydrosphere, and atmosphere. It includes processes such as photosynthesis, where plants convert carbon dioxide (CO₂) into organic compounds, and respiration, where these compounds are used by organisms and CO₂ is released back into the atmosphere.

The nitrogen cycle includes processes such as nitrogen fixation, where atmospheric N₂ is converted into a form usable by plants, and denitrification, where nitrogen compounds are returned to the atmosphere as N₂ gas. Both cycles are crucial for providing essential elements necessary for the growth and functioning of organisms, but they operate through different pathways and involve different forms of matter.

From an evolutionary perspective, what adaptive value do mirror neurons have?

Answers


Mirror neurons are said to be the factors behind social imitation. Neurons are the main cell of the nervous system which is responsible for communication of organs and control of many bodily functions. In an evolutionary standpoint, mirror neurons are an advantage because humans are able to replicate and imitate skills, behaviors and practices which they find beneficial and advantageous in the wild. Among their social peers, mirror neurons help these individuals practice social inclusion through culture, values and practices for increased group cohesion and cooperation.
Final answer:

Mirror neurons have adaptive value in enabling mimicry and understanding the actions of others, which is important for language development.

Explanation:

Mirror neurons have an adaptive value from an evolutionary perspective because they enable mimicry and the ability to understand and interpret the actions of others. This ability is thought to be a fundamental prerequisite for language development. In primates, such as monkeys, the mirror neuron system allows them to recognize and imitate actions performed by other primates. While the neurological studies of mirror neurons are invasive and cannot be performed on humans, neuroimaging studies suggest that a similar mirror neuron system exists in humans.

Answer:

Densely populated regions with little vegetation.

Explanation:

Flooding refers to a longer event in comparison to flash flooding, it may take a few days or weeks. On the other hand, flash floods are generally featured by intense fast-moving water post heavy rains, which gashes through urban streets, river beds, or mountain canyons sweeping everything coming in their way. They can take place within minutes or a few hours of extreme rainfall. In such cases, the regions with heavy population and comprising little vegetation would be the one that would be most affected.

Grasslands are considered transitional biomes. for which two biomes would grasslands be considered a transition? forest and tundra desert and savannah forest and savannah prairie and savannah desert and forest

Answers

Final answer:

Grasslands can act as a transitional biome between forests and deserts, as well as forests and tundras, specifically for forest and savannah, and prairie and savannah.

Explanation:

Grasslands are often referred to as transitional biomes because they can be found between forests and deserts, as well as between forests and tundras. These ecosystems are dominated by grasses rather than large shrubs or trees, and the two biomes for which grasslands can be considered a transition are forest and savannah, and prairie and savannah. The temperate grassland biome, for example, has characteristics that are intermediate between those of forests and deserts, where precipitation is too low to support a forest, but greater than that which would permit a desert to form.

Similarly, tropical and subtropical grasslands, which include savannas, act as a transition between tropical forests and more arid environments like deserts. These grasslands are characterized by seasonal droughts and fires which inhibit the development of tree-cover, making it a transitional zone between the lush forests and the dry deserts.

What is one way the vision of primates is different from that of other animals?

Answers

Us humans have trichromatic vision also known as three color vision. We have 3 types of light sensitive retinas in our eyes that appear green, blue and red. Howler monkeys is trichromatic. The owl monkey is monochromatic seeing in old black and white. Spider monkeys are dichromatic and can't see red or green.

Primates differ from other animals in their vision through forward-facing eyes allowing stereoscopic vision, advanced trichromatic color vision, and larger visual centers in the brain due to a high reliance on sight.

Primates possess forward-facing eyes with convergent visual fields, allowing for stereoscopic vision or three-dimensional vision, which is critical for depth perception. This trait, shared among all primates, is tied to their arboreal lifestyle and predation habits. The presence of a postorbital bar or plate provides structural support and protection for the eyes, a feature linked to the degree of orbital convergence among different primate species.

Additionally, many primates have trichromatic color vision, which permits them to distinguish more colors compared to most other mammals that are typically dichromatic. This advanced color vision is beneficial in activities such as foraging for food, as it helps in identifying ripe fruits and young leaves, and plays a role in social interactions by enabling the recognition of visual signals related to health and fertility.

The purple color in a purple pea plant is dominant to a white-color. what would be the expected outcome of a cross between a purple-flowered pea plant, and a white-flowered pea plant?

Answers

Well, it depends on the purple pea plant. Purple pea plants can have either PP or Pp.

White pea plants always have recessive, so it would have pp only.

So, the expected outcome of the cross would be - 
PP x pp or Pp x pp

PP x pp = all the offspring would be purple in colour 
 or 
Pp x pp = half would be purple and the other half would be white


For what side effects should the nurse ask the patient to be watchful when administering mixed alpha/beta agonists?

Answers

A agonist of alpha and beta receptores would be something like noradrenaline or epinephrine.
A agonist like that would cause the following side effects associated with the heart : vasoconstriction and the work of the heart increases. If the patient suffers from coronary heart disease, it would also cause angina, from the oxygen demand. Some other side effects would be sedation, impotence, bradycardia, orthostatic hypotension, and impotence, constipation, nausea, etc.

These types of drugs stimulate the adrenergic receptor sites and stimulate the release of norepinephrine from the terminal nerve ending. Adrenergic drugs stimulate the nerves in your body's sympathetic nervous system (SNS). This system helps regulate your body's reaction to stress or emergency. During times of stress, the SNS releases chemical messengers from the adrenal gland. These chemical messengers act on your body to increase heart rate, sweating, and breathing rate and to decrease digestion. This is sometimes called the fight or flight response.

What will happen to living systems if bicaarbonate, citrate and phosphate buffers didn't exist?

Answers

Buffers such as bicarbonate buffer, citrate buffer and phosphate buffer are important in living system. pH of blood is near to neutrality (7.4). If the pH of blood increases, these buffers help in maintaining the blood pH. Increase in blood pH leads to certain diseases such as alkalosis. This further leads to muscle spasm and respiratory diseases.

Bicarbonate buffer helps to maintain the blood pH if it falls towards acidic range or increases towards alkalinity. It helps in decreasing acidity and increasing alkalinity by forming carbon dioxide gas. Increase in blood pH towards alkalinity is also maintained by excreting the bicarbonates into the urine. Similar action is also seen in case of phosphate buffer and citrate buffer.

Answer: If these buffers are not present in a living system then the change of pH cannot be altered or put back to normal. These buffers help to maintain the pH of the living system so that cells can work properly.

A stream of water will bend toward a balloon that has been rubbed on a sweater to generate static charge. which property of water is responsible for this behavior ?

Answers

the polarity of the water molecule 

hope this helps have a great day

Answer:

The correct answer is the polarity of the water molecule.

Explanation:

When a balloon is rubbed on a sweater it acquires a charge on its surface that produces a static charge on it. Thus, when a stream of water is targeted over the balloon, the bending of the stream of water takes place towards the balloon that exhibits static charge over it, as water possesses a dipole moment of 1.85. The production of dipole moment takes place when there is a separation of charge between the terminals of the molecule.
