Answer: The fungi share a mutualistic association with the trees.
Mutualism is a relationship among two species, in which two species lives in close association with each other. In this relationship both the species are benefited.
The given situation, is an example of mutualistic association of the fungal species with the tree. This is because of the fact that the fungal species provides trees with nutrients after the process of decomposition, that are necessary for the growth of the trees. In return the fungal species obtains carbohydrates produced by photosynthesis from the roots of the trees. Therefore, both the species are benefited hence, it is a mutualistic association.
Answer: A.
The fungi share a mutualistic association with the trees.

As a result of habitat destruction, the size of the Florida panther population has been drastically reduced. It is estimated that there are only 100 to 160 Florida panthers in the wild. Which statement best explains why the Florida panther population may not continue to evolve?
There is no longer a chance of mutations occurring in the population.
There is a lack of competition for limited environmental resources.
There is no longer a chance of a trait providing a reproductive advantage to the population.
There is a lack of genetic variation for selection to act upon.
Answer:
The most appropriate answer would be "There is a lack of genetic variation for selection to act upon.".
Evolution is a gradual and natural process by which the characters of a population changes over several generations with the help of natural selection.
Reduction of population size up to 100 to 160 decreases overall genetic diversity of the population due to which the efficiency of natural selection decreases.
Consequently, the population of panthers may no continue to evolve.
Answer:
Option D , There is a lack of genetic variation for selection to act upon.
Explanation:
According to Darwin's theory of natural selection , when an organism undergo uncontrolled mating or sexual intercourse with other organism of the same species it gets an opportunity to produce offspring of varied genetic characteristics that are more fit to sustain in a given environment depending on the available gene pool . Now, in this case when panthers are killed ruthlessly, the number of panthers will reduce and so the gene pool will also shrink.
Therefore, the mating panthers will not get the benefit of selection as to produce a fit offspring that could sustain in a given environment and hence they would not evolve further.
Thus, option D is correct

A low return rate for a survey is likely to result in findings that are not generalizable to the entire population.
a. True
b. False
Answer:
True
Explanation:
Response rate is a term used to describe the provision of insights that determine whether a survey was done correctly with an accurate collection of relevant and important data for the correct completion of the survey, as well as for its application in society. This rate, therefore, refers to the number of individuals who participated in a survey divided by the number of individuals who make up the sample group. With that, we can conclude that if the response rate was low, this research is not appropriate to be applied to a population. This is because a low rate of return on a survey is likely to result in findings that are not generalizable to the entire population.

The ________ nervous system is responsible for stimulating digestion and causing the bladder to contract
Answer:
Parasympathetic nervous system.
Explanation:
Parasympathetic nervous system is one of the division of the autonomic nervous system, that regulates the proper functioning of the body.
Parasympathetic nervous system controls the process of digestion, conserves energy and slows the heart rate of the organisms. This nervous system causes relaxation of the sphincter muscles of the digestive tract. The bladder contraction is also caused the stimulation of the parasympathetic nerves.
Thus, the answer is parasympathetic nervous system.

what is the main cause of earthquakes and volcanic eruptions?
Final answer:
The main causes of earthquakes and volcanic eruptions are the movement and interaction of the Earth's tectonic plates, along with the release of energy as the plates shift along faults. Volcanic eruptions also occur when pressurized magma finds a way to the surface. Human activities can sometimes induce earthquakes and influence damage levels, though the fundamental causes are natural geologic processes.
Explanation:
The main cause of earthquakes and volcanic eruptions is the movement of the Earth's tectonic plates. Most earthquakes occur along faults, which are breaks in the Earth's crust where blocks of the crust move past each other. These movements can lock huge masses of rock in position for a long time before they abruptly shift, causing the ground to tremble. The driving mechanism behind these movements is the heat from the decay of radioactive elements within the Earth, and the associated tectonic activity.
Those same tectonic forces can also trigger volcanic eruptions. Magma formed deep within the Earth rises through the crust, and when pressure builds up, it can be released explosively through volcanoes. An eruption can release not just lava, but also gases, ash, and rock. Sometimes, water merging with sub-surface magma adds to the explosive force of eruptions, as in the case of the 1815 eruption of Mount Tambora in Indonesia.

When experimental results are statistically significant, this means the _____ hypothesis has been _____?
Answer:
___Null __ hypothesis has been _Rejected____
Explanation:
If the results obtained from the testing of a null hypothesis are statistically insignificant then it means that there were not enough proofs to support the null hypothesis and hence in virtue of insufficient proofs the null hypothesis is rejected.
The meaning of significant does not implies that statistically significant null hypothesis is important. However, it simply means that statistically insignificant hypothesis have high probabilities to provides less evidence in order to support the thesis.
The probability value of hypothesis must be less than 0.01 for a strong rejection of null hypothesis.

If a lawn is fertilized and it doesn't rain, the grass often dies. why?
Grass often dies after fertilization without rain because it cannot absorb necessary nutrients, may suffer from osmotic stress, and salt buildup can become toxic to the roots.
Explanation:Grass often dies when a lawn is fertilized and it does not rain due to several interrelated factors. Fertilizers often contain high levels of nitrogen, which is crucial for plant growth, but without sufficient water, the grass cannot absorb these nutrients. Additionally, rain is essential because it helps dissolve and distribute the fertilizer nutrients in the soil, making them accessible to the grass roots. Without rain, the fertilizer can actually draw out moisture from the soil in a process called osmotic stress, further parching the grass. Furthermore, the lack of water after applying fertilizer can lead to a buildup of salts, which can be toxic to the grass roots, exacerbating the damage and potentially leading to the death of the grass.

What are the two catabolic pathways that lead to cellular energy production?
Pepsin is produced by cells lining the stomach. It catalyzes reactions needed to digest certain proteins. After leaving the stomach, food enters the small intestine. The pH of the small intestine is around 7. What would most likely happen to pepsin enzymes that traveled with the food from the stomach to the small intestines?
Answer:
irreversible denaturation
Explanation:
Pepsin is a monomeric protein with two domains with a beta barrel architecture. The active enzyme site contains two aspartate residues. To activate, one of these aspartate residues must be protonic, while the other must be deprotonated. This occurs between the acidic pH (pH 1-5) provided by the HCl in the gastric juice. This is how the transition from pepsinogen to active pepsin occurs. However, above pH 7, pepsin irreversibly denatures.
What kind of metabolic poison would interfere with glycolysis?
Metabolic poisons that interfere with glycolysis include those affecting pyruvate kinase, leading to ATP production failure, and ethylene glycol, which causes metabolic and lactic acidosis.
Explanation:A metabolic poison that could interfere with glycolysis is one that affects enzymes involved in the glycolytic pathway. For instance, compounds that impair the function of pyruvate kinase will hinder the last step of glycolysis, causing a critical reduction in ATP production, especially in red blood cells (RBCs) that rely solely on glycolysis for their energy. Another example is ethylene glycol poisoning, which leads not only to metabolic acidosis due to accumulated glycolic acid but also lactic acidosis, contributing to the inhibition of metabolic pathways.
All amino acids have a central carbon with four components attached to it. One of these components is called the R group. Which of the following best describes the R group?
A.The R group is what stabilizes the amino acid.
B.The R group is the same in all amino acids.
C.The R group gives the amino acid unique characteristics.
Answer:
(C).The R group gives the amino acid unique characteristics.
Explanation:
Amino acids can be defined as compounds, having carbon, nitrogen, oxygen, and hydrogen atoms. Ech amino acid is made up of a carboxylic group, an amino group, a side R chain, and a hydrogen atom.
The R group provides specific characteristics to the amino acids and amino acids are classified into three categories, on the basis of their side chain or R group:
-Amino acids having non-polar R group (such as alanine and valine)
-Amino acids having uncharged, polar R group (such as tyrosine and serine)
-Amino acids having charged, polar r group (such as lysine and glutamate).
Thus, the correct answer is option (C).

Due the effects of alcohol on your __________, you may experience tunnel vision.
Answer: Peripheral vision
Explanation:
Whenever there is loss of peripheral vision without their affect on central vision then tunnel vision occurs. In tunnel vision , a person is only able to see what directly lies in front of the eyes but the object in the periphery is not visible. There are many reasons why tunnel vision may occur and this is one of the many detrimental effects of alcohol.Thus, a decreased peripheral vision results in the tunnel vision due to alcohol.
