In no less than 300 words, summarize General Strain Theory, Social Control Theory, and Social Learning Theory. Provide an example for each.
Answers
General Strain Theory, Social Control Theory, and Social Learning Theory are among the leading criminological theories that explain criminal behavior, delinquency, and the reasons why people deviate from the social norm.
General Strain Theory(GST) is a sociological theory that asserts that individuals' strain or stress can lead to criminal behavior. According to GST, three sources of strain; failure, negative stimuli, and separation can contribute to an individual's deviant behavior.
Example: Suppose a person is looking for work but is continually refused because of his age. This may cause the person to feel frustrated and may lead him to engage in criminal behavior.
Social Learning Theory asserts that people learn to be violent or non-violent based on observation and modeling from their environment, and people in their social surroundings. The theory argues that people will engage in criminal behavior if they think the benefits outweigh the negative consequences. the theory also suggests that people are more likely to be violent if they feel their environment encourages it.
Example: A child might be exposed to a parent who uses violence as a means of problem-solving. They may grow up believing that violence is the only way to solve problems and begin engaging in violent behaviors themselves.
Social Control Theory argues that people do not commit crimes or deviant behavior because they fear the negative consequences of doing so and they are less likely to engage in deviant behavior as they have stronger ties to society.
Example: A person may choose not to engage in criminal behavior because they fear the punishment that may come with it.
In conclusion, these three theories attempt to explain criminal behavior and deviant behavior from different perspectives. While General Strain Theory argues that strain or stress leads to deviant behavior, Social Control Theory suggests that people will refrain from criminal activity because of the consequences. Social Learning Theory asserts that people learn from their environment and the people in it and may model or imitate their behavior.

Answers
Answer:
The scientists should look for samples that do not have a nucleus or cell membrane when viewed under the microscope.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles. Some examples of cell organelles with their respective functions in all living organisms such as trees, birds, and bacteria include; nucleus, cytoplasm, cell membrane, golgi apparatus, mitochondria, lysosomes, ribosomes, chromosomes, endoplasmic reticulum, vesicles, etc.
Generally, all nonliving organisms or things do not have life or cells in them and as such are devoid of cell organelles.
In this scenario, the scientists are planning an experiment using a light microscope to collect data. Thus, the statement which best describes how the scientists can identify nonliving samples is that, the scientists should look for samples that do not have a nucleus or cell membrane when viewed under the microscope.

Answers
The correct answer is Option 4: A late-fall fertilizer application be made to cool-season grasses. When mowing is no longer needed, follow the one-third rule.
When mowing is no longer necessary to adhere to the one-third rule, cool-season grasses should be fertilised late in the fall to prepare the lawn for winter.
This normally happens towards the end of October or the beginning of November, when the grass starts to slow down.
Applying fertiliser now aids in the grass' ability to store energy for the impending cold season. Additionally, it aids in restoring the nutrients that were depleted throughout the summer.
Late fall fertiliser applications also aid in thickening the grass and producing a denser turf, which enhances the general appearance of the lawn.

______________________ are modern corals that have a symbiotic relationship with dinoflagellates.
Answers
Zooxanthellae are modern corals that have a symbiotic relationship with dinoflagellates.
The dinoflagellates belong to the genus Symbiodinium and are commonly referred to as zooxanthellae when they form a symbiotic association with corals. This relationship is crucial for the survival and growth of coral reefs. The corals provide a protected environment and necessary nutrients for the zooxanthellae, while the zooxanthellae photosynthesize and provide the corals with energy in the form of organic compounds.
This mutualistic relationship enables corals to thrive in nutrient-poor tropical waters and is responsible for the vibrant colors seen in coral reefs. The symbiotic relationship between corals and zooxanthellae is highly beneficial for both partners. The zooxanthellae provide corals with up to 90% of their energy needs through photosynthesis, producing sugars and other organic compounds.

Answers
In simpler words, the exchange of genetic material between homologous chromosomes during meiosis is referred to as crossing over. The main purpose of crossing over is to create genetic variation, which is necessary for evolution.
The term that should be included in the answer is "crossing over."When genes are located so close together on the same chromosome, a reduced possibility of crossing over will occur. This means that the chance of separation and recombination of the alleles will be lessened. As a result, the genes will not follow the traditional Mendelian genotypic ratios.What is crossing over?Crossing over is a process of exchange of genetic material between homologous chromosomes. In crossing over, two chromatids, one from each of the homologous chromosomes, exchange genetic material to produce two recombinant chromosomes that have a mixture of both paternal and maternal genes.In simpler words, the exchange of genetic material between homologous chromosomes during meiosis is referred to as crossing over.

what structural features of alveoli make them an ideal place for gas exchange
Answers
The structural features of alveoli make them an ideal place for gas exchange due to their large surface area and thin walls.
Alveoli are tiny, balloon-like structures found in the lungs. They are surrounded by an extensive network of capillaries, where the exchange of gases takes place. The large number of alveoli in the lungs provides a significantly large surface area for gas exchange to occur. This increased surface area allows for a greater amount of oxygen to diffuse into the bloodstream and carbon dioxide to be removed efficiently. Furthermore, the walls of the alveoli are extremely thin, consisting of a single layer of epithelial cells. This thinness enables gases to diffuse quickly across the alveolar membrane. The close proximity of the alveolar walls to the capillaries allows for a short diffusion distance, ensuring a rapid exchange of gases. Overall, the combination of the large surface area and thin walls of alveoli maximizes the efficiency of gas exchange in the lungs, facilitating the uptake of oxygen and the removal of carbon dioxide from the bloodstream. This ensures an adequate oxygen supply for cellular respiration and the elimination of waste gases produced by metabolic processes.

Answers
The correct answer is iterative evolution. A crocodile-like morphology evolved independently in a group of Triassic reptiles called phytosaurs, and later, after phytosaurs were extinct, in true crocodiles. This is an example of iterative evolution.
Iterative evolution is the development of similar structures or forms independently over time in separate lineages. This is frequently seen in unrelated lineages of organisms that evolve similar features through convergent evolution. The crocodile-like morphology that evolved independently in Triassic reptiles called phytosaurs and later in true crocodiles is an example of iterative evolution as they evolved independently in separate lineages. The ability of the phytosaurs to thrive in an aquatic environment likely contributed to the development of this morphology, which later allowed true crocodiles to similarly thrive.

Answer: A
Explanation: The elements in the compounds get rearranged. You can't change the amount of hydrogen, oxygen, or carbon the product contains
The equation that shows the conservation of matter is 6H₂O + 6CO₂ → C₆H₁₂O₆ +6O₂, which is in option a .Hence, the correct option is the option a, as it represents the process of photosynthesis.
In this equation, it represents the process of photosynthesis, where six molecules of water (6H₂O) and six molecules of carbon dioxide (6CO₂) react to form one molecule of glucose (C₆H₁₂O₆) and six molecules of oxygen (6O₂). This equation follows the law of conservation of matter. The law of conservation of matter states that matter cannot be created or destroyed in a chemical reaction. It can only change form or be rearranged. In the given equation, the number of atoms of each element is the same on both sides of the arrow, which means the total number of atoms before the reaction is equal to the total number of atoms after the reaction. Hence, the correct option is the option a.

Small cut pieces of soft stems are placed in growth medium with following plant hormones. Which combination of plant hormones will show slowest growth?
A) Auxim+Cytokinin
B)Gibberellins+Auxin
C) Gibberellins+Cytokinin
D)Abscisic Acid +Auxin
Answers
Option D: Abscisic Acid + Auxin is the combination of plant hormones will show slowest growth because abscisic acid is a growth inhibiting hormone.
Auxin, gibberellin, and cytokinin are growth-promoting hormones, but abscisic acid inhibits growth. While all of the growth-promoting hormones are present in options A, B, and C, both growth-promoting and growth-inhibiting hormones are present in option D. As a result, this hormonal mix will result in the slowest growth. Hence, choice D is the right response.
Auxins, cytokinins, gibberellins, ethylene, and abscisic acid are the five main categories of plant hormones, and they are distinguishable from one another by their chemical compositions and the reactions they cause in plants. Any cell must be able to recognize the molecule in order to react to a hormone. A cell's ability to detect a hormone depends on its physiology at the time the hormone is present.

which feature of the genetic code ensures that translation of a single mrna sequence will always result in the same amino acid sequence?
Answers
The feature of the genetic code that ensures that the translation of a single mRNA sequence will always result in the same amino acid sequence is the codon-anticodon pairing.
Codons and anticodons match up during protein synthesis to create the polypeptide chain. There are 20 amino acids in proteins, and 64 different codons exist in the genetic code. The genetic code is read in a 5′ to 3′ direction. The first nucleotide in the codon is located on the 5′ end of the mRNA, whereas the last nucleotide is located on the 3′ end of the mRNA.
The genetic code is degenerate, which means that more than one codon corresponds to the same amino acid. The only exceptions are methionine and tryptophan, which have just one codon that codes for them. As a result, the codon-anticodon pairing guarantees that a single mRNA sequence will always result in the same amino acid sequence.
