Antagonism can take one of two forms: competitive and non-competitive. Ketamine, on the other hand, is a non-competitive foe of the NMDA-glutamate receptor, whereas naloxone is a competitive foe of all opioid receptors. The correct answer is Antagonism.
Competitive antagonism is based on the idea that an agonist or antagonist can bind to the same recognition site(s) on the receptor and compete for those sites when they are present simultaneously.
A competitive antagonist blocks the agonist's action by binding to the same site as the agonist but not activating it. To prevent the receptor from being activated, a non-competitive antagonist binds to an allosteric (non-agonist) site on the receptor.

Answers
Exponential growth refers to a rapid and continuously increasing rate of population growth over time, resulting in a steep upward curve on the graph.
It took 1649 years for the world population to double, going from 0.25 billion people to 0.50 billion people. To double once again, it would take the same amount of time, approximately 1649 years. A third doubling would also take approximately 1649 years.
The population doubled for the second time in the year 1950. It took around 100 years for the population to double for the second time.
Extending the graph to the year 2015, you would add data points for that year. The specific values would depend on the available population data for that year.
According to the graph, the population is projected to reach 10 billion around the year 2050.
Based on the graph, it appears that the population of 2000 will double in approximately 40 years. However, since the specific year for the population value of 2000 is not provided, the exact number of years cannot be determined.
The graph illustrates exponential growth. This term means that the population is increasing at an accelerating rate over time. As the population grows, the rate of increase becomes more significant, resulting in a steep upward curve on the graph. This indicates a rapid and continuous growth pattern rather than a linear or constant rate of growth.

O a history of normal medical exams
O significant pain in a specific area
O a preoccupation with the idea of being sick
O an onset of the disorder before the age of 30
Answers
Answer:
C. a preoccupation with the idea of being sick
Explanation:
Hypochondriasis and pain disorder are two conditions that deviates from the normal human health. Hypochondriasis, also known as health anxiety, is a condition whereby an individual is fearfully worried about having a serious illness. On the other hand, pain disorder is a condition in which pain results in certain areas of an individual's body due to psychological disposition of such individual i.e. his/her mindset.
Based on the description of both conditions above, it can be observed that both hypochondriasis and pain disorder are as a result of a preoccupied mindset of being sick. One is worried PSYCHOLOGICALLY about being terribly ill (Hypochondriasis) while the other PSYCHOLOGICALLY induces pain on him/herself.

What is water pollution?MIxing of unwanted toxic substances in the water is called water pollution. Agricultural runoff caused the most change in stream diversity. Industrial pollution caused the greatest change in pH, it make the water more basic.
Thermal pollution increases water hardness because of increasing temperature, and mineral dissolves. Agricultural pollution shows evidence of eutrophication because of high nitrate levels. High level of nitrogen and phosphorus causes eutrophication which makes the water hypoxic.
Trout are the only aquatic species that are not able to tolerate any type of pollution in the stream. Pollution adversely affects human health and causes many types of diseases.

2. How does the frequency of a wave relate to the energy of the wave?
Type your answer here:
Answers
1. The energy of the wave is quadrupled if the amplitude is doubled.
2. The frequency of a wave is not directly related to its energy.
1. When the amplitude of a wave is doubled, the energy of the wave increases. The amplitude of a wave represents the maximum displacement of particles in the medium from their equilibrium position. As the amplitude increases, the particles oscillate with greater displacement, resulting in more energy being transferred through the wave.
The energy of a wave is directly proportional to the square of its amplitude. This means that if the amplitude is doubled, the energy of the wave will be quadrupled (increased by a factor of four). This relationship holds true for various types of waves, including mechanical waves like sound waves and electromagnetic waves like light waves. Therefore, doubling the amplitude of a wave leads to a significant increase in its energy content.
2. The frequency of a wave is not directly related to its energy. The frequency of a wave refers to the number of complete oscillations or cycles it undergoes per unit of time. On the other hand, the energy of a wave is determined by its amplitude, which represents the magnitude or intensity of the wave.
While frequency and energy are independent properties of a wave, they can indirectly affect each other. For example, in certain wave phenomena, such as the photoelectric effect, higher frequencies of electromagnetic waves (e.g., light) are associated with higher energy photons. However, this relationship is specific to certain interactions and is not a general rule that applies to all types of waves.
In summary, the frequency of a wave and its energy are distinct properties. The energy of a wave is primarily determined by its amplitude, while frequency relates to the number of oscillations per unit of time.

Write an essay that provides a scientific explanation for the question: How did the UCSD (campus) population of juncos become bolder than the mountain population over the last 60 years? Your essay should be
Answers
Answer:
The population of juncos at the University of California, San Diego (UCSD) campus has become bolder than the mountain population over the last 60 years, and this change can be explained by the process of natural selection.
Juncos are small, sparrow-like birds that are found in a variety of habitats across North America. The UCSD campus population and the mountain population of juncos are two distinct groups that have evolved separately over time.
One important factor that drives the process of natural selection is the availability of resources, such as food and shelter. On the UCSD campus, the juncos have access to a variety of resources provided by humans, such as bird feeders and landscaped gardens. These resources allow the juncos to survive and reproduce more successfully than they might in the wild, leading to an increase in the population size.
As the population size increases, there is more competition for resources, and only the boldest individuals can access them. Over time, bolder individuals are more likely to survive and reproduce, passing on their genes for boldness to the next generation. As a result, the overall population becomes bolder over time.
In contrast, the mountain population of juncos likely has fewer resources available and faces more challenges in finding food and shelter. As a result, the selection pressure for boldness is likely to be weaker in this population, leading to less of a change in the overall level of boldness.
Therefore, the difference in the level of boldness between the UCSD campus population and the mountain population can be explained by the process of natural selection, which has favored bolder individuals in the campus population due to the availability of resources provided by humans.

C. they will be more apt to acquire a serious case of malaria
D. they will have full-blown sickle-cell disease because the allele is dominant
E. none of the listed choices are correct
Answers
If an individual is heterozygous for the sickle cell trait, they will show not develop sickle cell disease. Option A.
Sickle Cell DiseaseSickle cell anemia is a disease of the blood that is homozygous and recessive. Consequently, an individual needs to have two copies of the recessive allele in order to be affected by the disease.
Now, if an individual is heterozygous for the sickle cell allele, it means such an individual has only one recessive allele which is not enough for the disease to be expressed.
This is why individuals that are heterozygous for the sickle cell trait don't show symptoms of the sickle cell disease. Instead, they enjoy a hybrid vigor that confers malaria resistance. Hence, they do not have malaria as often as those that are homozygous dominant.
Homozygous recessive traits are different from dominant traits. In the latter, only a copy of the allele is needed to be dominant, at least, in order for the trait to be expressed.
