Answer:
The answer is "supported and when fruit was removed"
Explanation:
It dated the idea from this laboratory because the distribution of avian beaks differed. If any kind of food available keeps shifting, the frequency of the beak types changes as beaks with beaks is far more suitable for food available. The data in this laboratory confirmed the theory, so because the fruit was removed by birds. These results of this laboratory confirm this idea because the dispersion of pigeons when food was taken was varied.
Answer: 1. supported 2. when fruit was removed

A scientist was studying a population of elephants. The first year, he counted a population of 80. Over the next eight years, the population's numbers were 94, 100, 103, 110, 125, 120, 125, 120. What appears to be the carrying capacity for this population? 120 124 125 126
Answer:
125
Explanation:
The correct option would be 125.
The carrying capacity of a particular environment generally refers to the maximum number of individuals of a particular species that the environment can support at a particular time based on the resources it has. Hence, the maximum population of a species will normally oscillate around the carrying capacity of the environment where it is found.
In the case of the elephants in the illustration, the maximum population recorded was 125. The population decreased from this value at some point only to increased back to it later.
Hence, the carrying capacity for the elephant is 125.
Answer:
125

What is an Obligate anaerobe? How do obligate anaerobes, like the bacteria C. Botulinum, get energy ?
Answer:
See the answer below
Explanation:
Obligate anaerobes are microbes that can only survive in oxygen-deficient environments. They are killed by the normal atmospheric level of oxygen and will only thrive in environments whose oxygen levels are lower than that of normal atmospheric level.
Obligate bacteria such as Clostridium botulinum obtain their energy through anaerobic respiration processes such as fermentation and anaerobic respiration. During this process of fermentation, the lactic acid pathway is mostly used but other fermentation pathways such as propionic acid, mixed acid, acetogenesis, and methanogenesis pathways can be used.

What is the difference between food chains and food webs?
1. Food webs show the flow of energy from producers to consumers, and food chains show the flow of energy from consumers to producers.
2.Food chains show a single path of energy in an ecosystem, and food webs show overlapping pathways of energy in that ecosystem.
3.About ten percent of the energy is passed on to the next trophic level in food webs, but in food chains, about ninety percent is passed on to the next trophic level.
4.Heat is lost when energy is passed on to the next trophic level in food chains, but in food webs, heat is not lost when energy is passed on to the next trophic level.
Answer:
2. Food chains show a single path of energy in an ecosystem, and food webs show overlapping pathways of energy in that ecosystem.
Explanation:
A food chain is a single chain representing who eats whom in a system of organisms. A food web is a system of food chains, involving overlapping pathways of different foodchains.
Answer:
2.Food chains show a single path of energy in an ecosystem, and food webs show overlapping pathways of energy in that ecosystem.
Explanation:
A food chain shows only a targeted path, while a food web shows a more realistic path. See attached photos.
First picture: Food Chain: Notice how it only shows one path from producer to tertiary consumer.
Second picture: Food Web: Notice the many pathing that connects for certain organisms in the food web. It shows a more realistic distribution of energy in a real world scenario.

Which answer best defines what the Lotka-Volterra predator-prey model mathematically describes?-The competition among many predator species for a dingle prey species.-The simultaneous effect of a predator population on a prey population and a prey population on a predator population over time.-The effect of a predator population on a prey population.-The capture efficiency and assimilation rate of a predator, which is dependent on the number of individuals in a prey population.
Answer:
The simultaneous effect of a predator population on a prey population and a prey population on a predator population over time.
Explanation:
The mathematical models of Lotka-Volterra equations explain the existing interaction between species in which prey and predator influence and affect each other. The model follows a few assumptions,
The ecosystem is isolated and closed. There is no migration. The whole individuals are reproductively equivalent. In the absence of the predator, prey shows an exponential growth rate. The prey is in the ideal environment. When there is no prey, the predator population decreases exponentially because of the lack of food. The predator environment is ideal, but it is limited by prey density. The predation rate is proportional to the encounters rate, which also depends on density. The predators affect the prey populations, inducing its decrease proportionally to the number of prey and predators present. The prey population also influences the predator population proportionally to the number of encounters between the two species.In these equations, the variable D is the number of predators, and P the number of prey items.
The parameters are always constant:
• r1: prey growth rate.
• a1: predator hunting success.
• r2: predator growth rate.
• a2: the success of the predator in hunting and feeding.
In nature, many factors affect interactions, such as dense-dependent factors and dense-independent factors. Also, in reality, there are stochastic factors. Stochasticity refers to the variability in the system involving those factors that are affecting or influencing population growth. Stochasticity might be related to good years and bad years for population growth.
In real situations, the compliance of the whole assumption does not occur. The previously mentioned constants might vary, constantly changing the interaction between the predator and the prey. These parameters change in different degrees, resulting in varying circumstances for both species.
There is a new trend to focus on dopamine receptor sensitivity rather than on dopamine itself because
Answer:
There is no scientific evidence to prove that people with schizophrenia ingest dopamine capable of accumulating excess in the body.
Explanation:
Although you did not specify that your question is associated with the origin of schizophrenia in people, we can see that this is the main topic of your question, due to its context. This is because scientists have been striving to find the origin of this disease, in order to be able to combat it in the early stages. Although many scientists believe that the origin of this disease is associated with excessive intake of dopamine, there is not strong enough scientific evidence to show that this is true. Because of this lack of evidence, filmmakers have focused on associating the origin of the disease with the sensitivity of the dopamine receptor and not with the dopain itself.
Cyanide inhibits cytochrome c oxidase, a component of the electron transport chain. If cyanide poisoning occurs, would you expect the pH of the intermembrane space to increase or decrease
Answer:
Increases.
Explanation:
The pH of the intermembrane space increases as the poisoning of cyanide occurs. After cyanide poisoning, the electron transport chain can stop pumping of electrons into the intermembrane space. The pH of the intermembrane space would increase, the pH gradient would also decreases, and ATP synthesis would stop to occur. The pH of the intermembrane space is neutral i.e. 7 but due to cyanide it move towards basic.
Answer:
Cyanide inhibits cytochrome c oxidase, a component of the electron transport chain. If cyanide poisoning occurs, the pH of the intermembrane space becomes more basic. The electron transport chain can no longer pump hydrogen ions into the intermembrane space and ATP synthesis stops.

Speech is a dynamic process requiring precisely coordinated articulatory movements for the sequencing of sounds to ultimately produce words. What is common among children with cerebral palsy
Answer:
Speech impairment
Explanation:
Cerebral palsy children suffers speech impairment and it is the inability to produce speech sounds and this may range from mild to severe. This can include an articulation disorder, fluency disorder and voice disorder.
fluency disorder is characterized by inability to pronounce a sound or repitition of a particular sound.
voice disorder is characterized by the production of abnormal pitch or volume.
Articulation disorder in the inability to articulate words, it could include stammering.
If you are interested in the evolutionary relationship of animals that have four limbs, which of the following would be the outgroup? Group of answer choices Sharks Ray-Finned Fish Amphibians Crocodiles Dinosaurs
Answer:
First outgroup → Ray-Finned FishesSecond outgroup → SharksExplanation:
The outgroup is the most distant taxonomic group that shares no traits or characters with the lineages of interest, which compose the ingroup. You can compare the outgroup with the ingroup to determine the evolutive relationship and which characters are primitive or derived.
Even though the outgroup shares a common ancestor with the ingroup, this is placed far away in evolution, making the outgroup to be the taxonomic group less related to the other lineages. The lineages in the ingroup share another common ancestor that is more recent in history.
To select the outgroup, you need to focus on what you are interested in. There might be several outgroups, but you should choose the one that is more related or closer to the ingroups. This selection is important because you need to make comparisons to understand the evolution of specific traits.
In the exposed example, we need to focus on animals that have four limbs. Then, we might assume that the ingroup is composed of Amphibians Crocodiles Dinosaurs. Sharks and Ray-Finned Fish do not have four limbs, so they might be considered outgroups.
From these two outgroups, sharks have a cartilaginous skeleton, while Ray-Finned Fishes have a bony skeleton. This fact makes ray-finned fishes more related to the ingroup than the sharks. So,
First outgroup → Ray-Finned FishesSecond outgroup → Sharks.Discuss the THREE types of evidences of evolution to show that all organisms are related to each other: fossil record, comparative anatomy, AND molecular evidence. ALSO, give an example of each.
Answer:
1. fossil record:
Fossils are organisms that get buried in sedimentary rocks. These are formed at different times. The study of fossils existing in the different rock layers indicates the time period when they existed. Thus different life forms have been formed at different times in the history of the earth.
fossil bird Archaeopteryx is considered as a connecting link between reptiles and birds indicating that birds evolved from reptiles.
2 comparative anatomy:
Homologous organs - such organs that have different embryonic origins but play different roles.
The forelimbs of whale, bat, deer, rabbit
Homologous organs - such organs that are the same in structure and embryonic origin but play similar roles.
wings of a bird and wings of the insect. The wings of the birds are modified
3. DNA sequence can be helpful in finding relations among organisms. Biogeography also helps in identifying the geographical distribution of organisms, to know how and when species may have evolved.
Just after they taste a sweet liquid, mice are injected with a drug that produces an immune response. Later, the taste of the sweet liquid by itself triggers an immune response. This best illustrates
Answer:
This question lacks options, options are:
a) classical conditioning
b) observational learning
c) spontaneous recovery
d) operant conditioning.
The correct answer is a.
Explanation:
The classical conditioning theory derives from the experiments of the Russian physiologist Ivan Pavlov, he hypothesized that when any stimulus predicts the occurrence of another stimulus that triggers an automatic response, that first stimulus would acquire the ability to trigger that response, in other words , is a type of learning according to which an originally neutral stimulus, which does not provoke a response, becomes able to provoke it thanks to the associative connection of this stimulus with the stimulus that normally provokes said response. The conditioning of the immune response is built on the same principles of the classical conditioning paradigm described by Ivan P. Pavlov in which an environmental stimulus that by itself does not produce any immune reaction (conditioned stimulus), is associated with substances that stimulate or they suppress immune function (unconditioned stimulus), and finally, by presenting the conditioned stimulus alone, trigger the appropriate immune response.
Question 2 of 10
Which of the following should be included in a good conclusion?
Answer:
How to write a conclusion
An effective conclusion is created by following these steps:
Restate the thesis: An effective conclusion brings the reader back to the main point, reminding the reader of the purpose of the essay. However, avoid repeating the thesis verbatim. Paraphrase your argument slightly while still preserving the primary point.
Reiterate your supporting points: Aside from restating your thesis, you should also reiterate the points that you made to support it throughout the paper. But instead of simply repeating the paper's arguments, summarize the ideas.
Make a connection between your opening and closing statements: It's often effective to return to the introduction's themes, giving the reader a strong sense of conclusion. You can accomplish this by using similar concepts, returning to an original scenario or by including the same imagery.
Provide some insight: Your conclusion should leave the reader with a solution, an insight, questions for further study or a call to action. What are the implications of your argument? Why should anyone care? You'll want to answer these types of questions here and leave your audience with something to think about.
