Answer: Family, Social and Neglect

Explanation:

Family Risk Factors: Family risk factors include childhood maltreatment in which the parent child relationship, marital status of parents, level of understanding among the family members also influences the abuse of alcohol and drug abuse.

Social Risk Factors: The society in which the person or child is living also influences the drug, tobacco and alcohol abuse. A teenage easily gets influenced by the society and place where they are living.

Neglect: If a person feels neglected emotionally by the partners or parents then there is an increased chance of alcohol or drug abuse. If the important necessities of life such as education, clothes, food is fulfilled by the guardians then also there are  chances that a person might get towards alcohol and drug abuse.

Substance abuse is influenced by family history, witnessing domestic violence, and media exposure. Genetic predisposition, particularly related to alcoholism, and one's sociodemographic background also play roles in the likelihood of substance abuse, which has significant individual and societal impacts.

There are several factors that contribute to the abuse of alcohol, tobacco, and other drugs. One critical factor is family influence, where having family members afflicted with alcoholism or drug abuse increases the likelihood of substance abuse in offspring. Witnessing violence between parents or caretakers is another factor, as it can lead to substance use as a coping mechanism. Additionally, a third factor is the exposure to and normalization of substance use through media, such as watching disproportionate amounts of violence or drug use on television.

Genetic predisposition is also discussed as a contributing factor, especially pertaining to alcoholism. Although research is more conclusive on alcohol than other drugs, there is evidence to suggest that those born to alcoholic parents may have a higher risk of developing similar problems themselves. This predisposition combined with sociodemographic backgrounds and environmental factors serves to heighten the risk of substance abuse.

The use of substances like alcohol and tobacco can also be attributed to the physiological, psychological, and social satisfaction they provide, making them appealing despite their harms. It's essential to consider these factors when addressing and creating policies to combat substance abuse. The harms caused by substance abuse are significant, impacting not only the individual but also leading to broader societal issues such as child abuse and neglect.

Answer:  (d) Assumption of conclusions without prior experimentation or observation.

Explanation:

A scientific investigation can be define as a fact finding inquiry which involves the detailed step by step procedure for answering the questions related to science. It involves steps like making an observation, creating a hypothesis, making a prediction depending upon the hypothesis, experimentation and analysis.

(d) Assumption of conclusions without prior experimentation or observation. is the correct option this is because of the fact that in a scientific investigation an assumption cannot be made. The assumption cannot lead to conclusive results and finding cannot be considered as reliable.

Answer:

The correct option will be option A (Input, graded potential).

Explanation:

The transfer of impulse through neurons takes place in the form of the action potential. these action potential are generated in the dendrite and moves along the axons which move to another nerve cell at the synapse.

Graded potential is the change in the membrane potential which can be depolarizing and hyperpolarizing depending on the stimulus. This graded potential which leads to action potential is generated in the postsynaptic dendrite.

Since dendrites receive the signals from the pre-synaptic axon of the neuron at a synapse it is also called the input region.

Thus,  option A (Input, graded potential) is the correct answer.

The kinetic and potential energy of the hawk as it dives and returns to its original position are inversely related, with one increasing as the other decreases.

The relationship of kinetic energy (represented by a solid line) to potential energy (represented by a dotted line) as a hawk dives towards its prey and then returns to its original position in the air would be best shown by a graph in which the kinetic energy increases as the potential energy decreases, and vice versa.

As the hawk dives (loses altitude), its potential energy (height) decreases, but its kinetic energy (speed) increases. When the hawk returns to its original position (regains altitude), its kinetic energy decreases while its potential energy increases. Therefore, the kinetic and potential energies should be inversely related on the graph.

In synaptic vesicles.

Neurotransmitter molecules are stored in vesicles within neurons. During neurotransmission, these vesicles release neurotransmitters into the synaptic cleft through exocytosis.

Neurotransmitter molecules are stored in small intracellular structures called vesicles. These vesicles are crucial for the transmission of signals in the nervous system, where they store neurotransmitters until the neuron is stimulated. Upon stimulation, the vesicles move toward the cell membrane and release their contents into the synaptic cleft through a process known as exocytosis. This release allows neurotransmitters, such as dopamine, to diffuse across the synapse and bind to receptors on the postsynaptic neuron, thereby transmitting the nerve impulse. Neurotransmitter systems, like the dopamine system, play a key role in neurological processes and behaviors, and their dysfunctions are related to neurological diseases such as Parkinson's and schizophrenia.

Neurotransmitter molecules are stored in vesicles inside neurons. These vesicles contain the neurotransmitters that are released into the synapse between neurons to transmit signals. When a neuron is appropriately stimulated, the vesicles fuse with the cell membrane and release their contents through a process called exocytosis.

Answer:

The muscles of the jaw consist of three muscles the Temporalis, Masseter and Pterygoid Muscles which work together to move the mandible at the Temporomandibular Joint.

Explanation:

Final answer:

The muscle responsible for chewing, among the given options, is the temporalis. The masseter is another major muscle for mastication. The sternohyoid, orbicularis oris, and scalenes have other functions like swallowing, moving lips, and assisting neck movement respectively.

Explanation:

Among the options provided, the temporalis muscle is the one that is responsible for chewing, also known as mastication. It is one of the chief muscles of mastication and is located in the temple. The temporalis muscle is attached to the lower jaw and when it contracts, it assists in closing the mouth by moving the mandible upward and backward.

In contrast to the temporalis, the masseter is another major muscle used for chewing because it elevates the mandible to close the mouth. This strong muscle is found in the cheek and plays a vital role in mastication. Both the temporalis and the masseter work together to exert the pressure necessary to bite and chew food before swallowing.

Answer:

The time required for the colony to grow two million bacteria is 29.22.

Explanation:

Time required for the colony to grow can be calculated by the following equation:

[tex]t=2log(N/80)/log 2.[/tex]

Here t is time, N = 2 million  (require bacteria population).

[tex]t=2log(2,000,000/80)/log2[/tex]

t ≈ 29.22

Time taken by bacteria to grow is 29.22.

The given question involves calculating the time required for a bacterial colony (which grows exponentially) to expand from 80 to two million bacteria. This can be done using the given mathematical formula t = 2 log(N/80) / log 2, where N represents the number of bacteria at a certain time.

The given question is about bacterial growth, which follows an exponential pattern. The formula to calculate the time required for the colony to grow to a specific number of bacteria is t = 2 log(N/80) log 2, where N is the number of bacteria at a certain time, and t represents time in hours.

For this situation, we need to find the time t for the bacteria colony to grow from 80 to two million bacteria. So we plug N = 2,000,000 into the equation and solve for t.

Therefore, t = 2 log(2,000,000/80) / log 2. After solving this equation, it gives the time required for the colony to grow to two million bacteria.

The state of Michigan has faced a big problem with an invasive species of plant in its wetlands. The plant is seemingly harmless and beautiful, and while there's no argument about the beauty of it, it is actually very destructive toward the local flora and because of it the fauna as well. In order to solve the problem with the purple loosestrifes, the state of Michigan has asked for help from the professionals in the universities to find out a solution. The scientists managed to figure out a way in which they can lower significantly the density of this invasive species and mostly restore the native flora, and the salvation was in certain species of insects. Some insects are natural predators of this plant, thus they destroy it, so several species of insects have been released at the places where this plant had spread out. The effects have been excellent, as the insects did their job properly, managing to reduce significantly the amount of purple loosestifes, enabling the native flora to get its territory back.

Answer:

The answer to the question, would be: during fatigue.

Explanation:

Normally, a muscle fiber will respond to neurological stimulation to perform movement. In this case, the whole process of movement of the fiber results from the biochemical processes that lead the muscle to respond to calcium and use ATP, so that the chain reactions can be carried out, and the fibers can move. However, there is a point at which, ATP is depleted, and there is an overproduction of lactic acid, which prevents muscle fibers from further responding to stimulation from the motor neuron, regardless of the amount of ACh released to bind with the sarcomeres´ receptors. At this point, then, the muscle fibers are incapable of further responding to stimultation, and thus movement is stopped.

Explanation:

Neurons are the fundamental unit of the nervous system. Neurons send information across the body through generation of  electric signals called as action potential. There are basically three types of neurons  

a) Sensory neurons which carry information from the sense organs in the form of impulse to the central nervous system (CNS)

b) Motor neurons – These carry information from the CNS to the body parts such as sense organs, muscles etc.

c) Interneurons – They are connecting neurons which are responsible for transferring information from one neuron to the other neuron.

Answer:

The major function of neuron is the transmission of nerve impulse.

Explanation:

Neurons or nerve cells are the electrically excitable cells that transmit information from one part of the body to another by transmitting nerve impulse. Neuron is the structural and functional unit of nervous system.

Sensory neurons carry nerve impulse from the receptor cell and transmit it to the brain. Inter neurons are present between sensory and motor neuron. Motor neurons carry information from the brain to the effector organ. Effector organ may be any muscles, glands or hormones.

Answer:

Due to the presence of high level of bilirubin.

Explanation:

Jaundice is the condition in which the skin and sclera of eyes turns into yellow.  Improper functioning of liver mainly causes the jaundice condition in an individual.

The skin and body turns yellow in jaundice because the bilirubin pigment is deposited in the blood. The bile juice of the liver mixes with the blood and causes the yellowing of the skin.

Final answer:

The sclera of the eyes turns yellow in jaundice because of the accumulation of bilirubin, a yellow pigment that is not properly processed when the liver is functioning abnormally.

Explanation:

The sclera of the eyes turning yellow as a result of jaundice is due to the build-up of a yellow pigment called bilirubin in the blood. Normally, the liver processes bilirubin, which is a by-product of the breakdown of old red blood cells. However, if the liver is damaged, has decreased function, or if there is a blockage in the bile ducts, bilirubin cannot be processed effectively and starts to accumulate in the blood. As bilirubin levels in the blood rise, it begins to diffuse into the body's tissues, causing the skin and the whites of the eyes to turn yellow.
