Answer:
1) carbon dioxide enters a plant and is used to make sugar; which is used to build plant tissue.
2) a primary consumer eats the plant. the plant's carbon enters the primary consumer.
3) carbon enters a high-level consumer when it eats the primary consumer. Some carbon exits as feces
4) fungi use the carbon that is found in the wolf's feces.
5) cellular respiration in fungi releases carbon dioxide to the atmosphere.
Explanation:
The above ilustration described a food chain involving the flow of carbon in the carbon cycle.
1) A food chain always begins with a PRODUCER e.g plants which undergoes photosynthesis to make its food (glucose sugar). Carbon in form of carbondioxide (CO2), which enters through the stomata of the plant is used in the photosynthetic process. Hence, photosynthesis removes carbon from the atmosphere.
2) An organism in the next TROPHIC LEVEL of the food chain called PRIMARY CONSUMER feeds on the plants. This causes the stored carbon in the plant to be transferred to the animal (primary consumer).
3) Another consumer higher than the primary consumer i.e. secondary and tertiary consumers eat the primary consumer, causing the carbon to be transferred to it. Some of this carbon is later released as feaces (undigested).
4) A set of organisms called DECOMPOSERS in ecology, which is the fungi in this case
begins to use the carbon source in the feaces as nutrients in order to grow.
5) Finally, the fungi undergoes cellular respiration which releases the carbon in form of carbondioxide (CO2) back into the atmosphere.
Carbon moves through organisms as it is taken in by plants and used to build tissue, then passed on to primary consumers, and eventually to high-level consumers. Fungi play a role in decomposing waste and releasing carbon back into the atmosphere through respiration.
Explanation:Carbon dioxide enters a plant and is used to make sugar, which is used to build plant tissue.A primary consumer eats the plant, and the plant's carbon enters the primary consumer.Carbon enters a high-level consumer when it eats the primary consumer.Some of the carbon exits the organisms as feces.Fungi use the carbon found in the wolf's feces.At the end, cellular respiration in fungi releases carbon dioxide back into the atmosphere.Learn more about Carbon movement in organisms here:https://brainly.com/question/33357525

Control of thirst response due to increased plasma osmolarity by a negative feedback loop rank from the first to the last steps to describe the correct order of events to maintain homeostasis.
Thirst response is controlled by the master of all endocrine gland i.e. the hypothalamus. The increase in the osmolarity of the cells causes the hypothalamus to trigger the thirst response. This is subsidized by fluid intake which helps in operating the feedback loop.
Further Explanation:
Feedback mechanism is the process by which the body tries to maintain a homeostasis. They are of two types,
a. Positive Feedback Loop
b. Negative Feedback Loop
Positive feedback loop is the self-regulating process in which the increase in input decreases the output. A sufficient decrease in the output leads to decrease in input.
Negative feedback loop is a self-regulating cycle in which the increase in input increases the output. The increase in output regulates the level of input.
Hypothalamus is the master endocrine gland that plays a vital role in maintaining homeostasis that is a stable condition inside the body.
The control of thirst response is carried out in the following manner,
i. The increase in osmoregularity of the cells.
ii. This increase is detected by the control center in the brain i.e. hypothalamus.
iii. Hypothalamus triggers the thirst response.
iv. The triggering helps in increasing the fluid intake.
v. The fluid intake is detected and the osmoregularity comes back to normal.
vi. The hypothalamus detects the change in osmoregularity.
vii. The change detected leads to decrease in thirst response.

Keywords:
Homeostasis, hypothalamus, fluid, Fluid intake, Brain, master endocrine gland, feedback mechanism, negative feedback loop, feedback loop, endocrine gland.
Final answer:
The control of thirst response due to increased plasma osmolarity is maintained by a negative feedback loop involving osmoreceptors signaling the hypothalamus to induce thirst and release ADH, leading to increased water reabsorption by the kidneys until homeostasis is restored. The correct order of events is: detection of increased plasma osmolarity, activation of osmoreceptors in the hypothalamus, thirst response and drinking water, release of antidiuretic hormone to recover water from urine, and decrease in watery output from salivary glands.
Explanation:
The body detects an increase in plasma osmolarity due to dehydration.The osmoreceptors in the thirst center of the hypothalamus monitor the concentration of solutes in the blood.If the blood osmolality increases above its ideal value, the hypothalamus signals thirst and the person responds by drinking water.The hypothalamus also releases antidiuretic hormone (ADH) through the posterior pituitary gland, which signals the kidneys to recover water from urine, diluting the blood plasma.To conserve water, the hypothalamus sends signals to the salivary glands, resulting in a decrease in watery output and an increase in stickier mucus output, causing a dry mouth and the sensation of thirst.This process efficiently regulates water intake and urine production to ensure that the body's plasma osmolarity remains within the optimal range.

Final answer:
The correct food web model shows a predator like a fox above its prey, a rabbit because arrows in a food web indicate the direction of energy flow from the eaten to the eater.
Explanation:
The model that presents a species relationship as it would typically be drawn within a food web is the Vertical model. From top to bottom, you would have a predator such as a fox, shown with a down arrow to a prey species such as a rabbit. This is because, in a food web, arrows represent the flow of energy from the organism being eaten to the organism that does the eating. Therefore, the correct sequence within a food web is the second option: Vertical model. From top to bottom: an oval with the label fox, a down arrow, an oval with the label rabbit.
what condition absolutely must be present in a population before evolution can act upon it ?
what condition absolutely must be present in a population before evolution can act upon it ?
Answer:Genetic variation
Genetic variation is the condition that must be present in a population for evolution to act upon it. This variation leads to evolutionary forces such as natural selection, mutation, migration, and drift, driving the genetic change in populations.
Explanation:The condition that absolutely must be present in a population before evolution can act upon it is genetic variation. This variation, or differences, among individuals in a population must have some genetic basis; otherwise, the selection will not lead to change in the next generation. Even Hardy and Weinberg recognized that no natural population is immune to evolution. Populations in nature are constantly changing in genetic makeup due to drift, mutation, possibly migration, and selection.
Evolution by natural selection arises from three conditions: individuals within a species vary, some of those variations are heritable, and organisms have more offspring than resources can support. This leads to advantageous traits being passed on to offspring in greater proportion, and the trait will have higher representation in the next and subsequent generations leading to genetic change in the population. The Hardy-Weinberg principle provides a mathematical baseline of a non-evolving population, allowing for comparisons and inferences about evolutionary forces.

Which of the following pairs are the best examples of homologous structures?(a) bat wing and human hand(b) owl wing and hornet wing(c) porcupine quill and cactus spine(d) bat forelimb and bird wing(e) Australian mole and North American mole
Answer:
(a) bat wing and human hand
Explanation:
The homologous structures are structures at living organisms that are the same, very similar, or have the same function, despite the organisms having different appearance. This can mostly be seen in the bones of the animals, and this type of structures more often then not suggest a distant common ancestor between the species. Usually the homologous structures appear among animals from the same class, so it can be expected that animals from the mammalia class can have these structures, or animals from the reptilia etc. In this case we have the bat wing and the human hand. Both have similar bone structure, and the function of the bones in the bat wing and the human hand is also similar. Both of them are in the class of mammalia, and they do share a very distant common ancestor in the small shrew-like mammals during the reign of the dinosaurs.
Water can leave the air as a result of which processes? A. infiltration or transpiration B. precipitation or evaporation C. evaporation or transpiration D. condensation or precipitation
Answer:
D
Explanation:
The water in the air is in its gas form. The act of evaporation is water in its liquid form turning into gas. Condensation and precipitation both are acts of water in its gas form turning back into its liquid form.
Answer:
The correct answer is: D) condensation or precipitation.
Explanation:
Condensation refers to the change in the state of water, from the gas phase into the liquid phase - making it the opposite of evaporation.
Precipitation is basically any product of the condensation of atmospheric water that falls under gravity. For precipitation to happen, the atmosphere must become saturated with water vapor.
Water in the air is normally in the gaseous phase and, in order to descend, it needs to go to the liquid state (rain).

Eliminate B) GMOs have reduced nutritional value compared to traditional crops. C) there is not enough research on long-term effects of consuming GMOs. D) GMO crops become invasive and take over the habitat of indigenous crops.
The answer is C.) There is not enough research on long-term effects of consuming GMOs
Answer:
D) GMO crops become invasive and take over the habitat of indigenous crops.
Explanation:
A "Genetically Modified Organism (OMG)" is any organism whose genetic material (DNA) has been modified in a way that does not occur naturally. Over 95% of all commercially grown transgenic plants belong to four species: soybean, corn, cotton, rapeseed and rice. While there are many advantages to using OMGs in agriculture, there are also disadvantages that have caused many controversies about this technology around the world.
One of the disadvantages that can be cited is that OMG crops can become evasive and take over indigenous and family acriculture land.
This is because whenever there is genetic contamination of conventional crops by transgenic pollen grains, these crops become transgenic and the companies responsible for the manufacture of transgenic seeds have the 'right' to own agricultural land (often indigenous land). because now it became his seeds that constituted the agricultural fields, and the owner, in addition to being without his crops, is still liable to pay compensation for having 'used' seeds that were not his own.

Methane hydrates are kept in sediments deep in the ocean by the cold temperature and high pressure. Some scientists are concerned that there could be a release of immense amounts of natural gas contained in methane hydrates. Why are climate scientists concerned about this?
Methane is a greenhouse gas, so its release would likely increase global warming.
Methane is toxic to marine organisms and would damage the ecosystem if released by killing species.
This would lead to massive pollution of drinking water.
We want to extract and use this gas as a fuel source, but it would be lost to the environment through this process.
Greenhouse, it’s release would most definitely increase global warming chances by a major amount.
Methane is a potent greenhouse gas, so its release would likely increase global warming.Therefore, option (A) is correct.
What are greenhouse gases?Greenhouse gases are gases that trap heat in the Earth's atmosphere and contribute to the greenhouse effect, which is the warming of the Earth's surface temperature. Methane is a powerful greenhouse gas, with a warming potential 28 times greater than carbon dioxide over a 100-year time frame.
It is produced through natural processes such as decomposition of organic matter, but it is also emitted as a result of human activities such as livestock farming, natural gas production and transport, and waste management. Methane emissions contribute significantly to climate change, and reducing methane emissions is an important strategy for mitigating the impacts of climate change.

What part of a neuron relays signals from one neuron to another neuron or to an effector?
Answer:
Synaptic terminal
Explanation:
Neuron or nerve cell is excitable cell of the nervous system which consists of cell body or soma (karyon), dendrites and an axon. Dendrites are short, numerous filaments responsible for the signal receiving. On the other hand, axon is long "filament" and it originates from the cell body from the swelling called axon hillock. At the end of an axon there are axon terminals (Synaptic terminals) from which neuron can transmit a signal another cell. Synaptic terminal is axonic end of presynaptic neuron.
Axons and their terminals, or synaptic terminals, are the parts of a neuron that relay signals to another neuron or an effector. They accomplish this through the release of neurotransmitters into a synaptic gap which can then bind to the next cell, transmitting the signal.
Explanation:The part of a neuron that relays signals to another neuron or to an effector is the axon and its terminal, also known as the synaptic terminal. The signals are sent across a gap called a synapse, which lies between the axon terminal of one neuron and the dendrites of another neuron. The axon terminal releases neurotransmitter molecules into this gap, these molecules then bind to receptors in the next neuron or effector cell's membrane, potentially initiating a response in that cell.

Summation that results from the cumulative effect of multiple synapses at multiple places on the neuron is designatedimpulse transmission.spatial summation.inhibition of the impulse.hyperpolarization.temporal summation.
Answer:
spatial summation
Explanation:
There are two types of neuron summation:
temporal-multiple repeated signals (target neuron receives a single form one neuron that is repeated)spatial-multiple simultaneous signals from multiple synapses (target neuron receives few different inputs).Since the signals might be excitatory (produce depolarization of the postsynaptic cell) or inhibitory (produce hyperpolarization) of the postsynaptic cell, their total sum might or might not trigger an action potential on neuron.
Spatial summation is the cumulative effect of multiple synapses at multiple places on a neuron, which can potentially initiate an action potential. Temporal summation refers to multiple inputs at the same place over time. Both types of summation can influence a neuron's signal transmission.
Explanation:The cumulative effect of multiple synapses at multiple places on a neuron is referred to as spatial summation. This is where signal inputs at different locations on a neuron add together, potentially initiating an action potential that is strong enough to be transmitted. The membrane potential itself is a balance of positive and negative charges across the neuron's cell membrane. If the excitatory potentials overcome the inhibitory ones and reach a certain threshold, an action potential is fired.
On the other hand, temporal summation refers to multiple inputs that occur at the same place but are spread out over time. Both spatial and temporal summation can work together to influence the neuron's signal transmission.
Lastly, there's the concept of a synapse, a small gap where neurotransmitter molecules are released by one neuron and received by another, and this helps signal transmission between neurons. A key area where summation occurs is the axon hillock, a place where synaptic end bulbs release neurotransmitters onto a target cell across a synaptic cleft.

Global warming has resulted in weather extremes. One such extreme is a general increase in the intensity of winter storms and a decrease in average winter temperatures. Discuss how the worsening of winter conditions in the Southern United States may alter the long-term behavior of a population of birds that depend on mild winters for food and reproduction.
The more extreme winter storms in the Southern United States will result in change of behavior or migration of the animals that live there. The reason for that is that the animals, in this case the birds, will not be able to get to enough food, so they will have to move to a region that will provide enough food for them to survive. These birds are used to mild winters and sufficient amount of food, but the more extreme winter conditions bring in temperatures that are not suitable for the birds, and on top of that the food sources will be damaged. This will force the birds to migrate further south, toward Mexico or Central America where the winter conditions would be much better for the birds and they will be able to sustain their populations.

A genetically modified organism (GMO) is any organism whose genetic material has been altered using genetic engineering techniques. The exact definition of a genetically modified organism and what constitutes genetic engineering varies, with the most common being an organism altered in a way that "does not occur naturally by mating and/or natural recombination". A wide variety of organisms have been genetically modified (GM), from animals to plants and microorganisms. Genes have been transferred within the same species, across species (creating transgenic organisms) and even across kingdoms. New genes can be introduced, or endogenous genes can be enhanced, altered or knocked out.

Sperm undergo capacitation in order to become functional and able to fertilize an egg.
Explanation:The correct answer is they undergo capacitation.
Sperm are not initially capable of fertilizing an egg as they go through a process called capacitation, which occurs in the female reproductive tract. During capacitation, the sperm undergo various biochemical and physiological changes that enable them to become functional and able to fertilize the egg.
Capacitation involves the removal of certain proteins and the modification of the sperm's plasma membrane, allowing it to acquire the ability to penetrate and fertilize the egg. This process usually takes several hours to occur.
