Answer:

Explanation:

When an individual experiences excessive and continuous worry and anxiety about certain events of life(families,job security} to the extent that this happens uncontrollably in the subject, and difficult to control, such neurological disorder is called generalized anxiety disorder (GAD).

It is caused by over activation or stimulation of the region of the brain(amygdala) that mediate response to fight and flight stimulus and fear.

It is usually diagnosed when the inability to control worries extends beyond days to months with symptoms like poor concentrations, overthinking ,indecision, inability to relax, continuous taking every event as life threatening and disrupted sleep patterns.

Generally, sensory stimuli of fear or danger in the brain are transmitted by two brain circuits to two regions of the brain, to the peripheral cerebral cortex for processing voluntary decisions about the situation, and the Amygdala for processing involuntary emotional decision.

Physiologically; it is the amygdala that processes how the body reacts to the effects of the stimuli in the immediate environments, the influence of the stimuli on the emotions of the subject, and the involuntary response to the stimuli by the subject.

In response to the sensory stimuli of fear It stimulates the hypothalamus, which in turn activate the circulatory and breathing centre of the brain.Therefore,hormones(adrenaline) are released into the blood stream to increase blood pressure, heartbeat, breathing rate, muscle contractions and other involuntary response to anxiety. This gives a fast response compare to the cerebral cortex which takes time to relay response.

Amygdala, generally stores memories of all emotions, fear, and anxiety. In GAD patients, their Amygdala is sensitive and had been adapted to the storage of fear and anxiety to the extent that every slight normal event which does would not portend danger is over reacted to with fear or flight response which triggers the two brain circuits described above to give anxiety-provoking events.

Intake of drugs, psychotherapy are the mode of treatments.

Vera_Pavlovna [14]

Cancer cells can arise in a variety of ways, the most common, however, tends to be genetic mutations.

Genetic mutations can occur during the life of a cell due to outside factors such as:

The food we eat
The environment we expose the cell to
The substances that touch the cell (e.g skin cells)

That being said, the most common time for a genetic mutation to take place is during cellular division. During this time the DNA that encodes the cells is duplicated. Genetic mutations in this DNA sometimes cause the elimination of programmed cell death.

Programmed cell death is what tells a cell when it should stop growing and dividing. This is a regulatory function designed to keep the number of cells at a balance, growing only when needed. As this cell multiplies, this produces an increasing number of cells that will not die. The accumulation of these cells is referred to as cancer.

kondor19780726 [428]

The coronary arteries supply blood to cardiac tissue. The left ventricle chamber of the heart requires the greatest amount of blood supply to keep it working.

Coronary arteries

The heart muscle receives blood from the coronary arteries. The heart muscle needs oxygen-rich blood in order to operate, just like all other bodily components do. Blood that lacks oxygen must also be transported away. Outside of the heart, the coronary arteries encircle the organ.

The coronary artery that is blocked the most frequently is the LAD artery. The interventricular septum, and therefore bundle branches of the conducting system, receive their primary blood supply from it.

Explain how these terms work together IN TRANSLATION: mRNA, tRNA, codon, amino acid, and protein.

slega [8]

Answer:

The mRNA leaves the nucleus and travels to the ribosome where proteins are synthesized

Explanation:

During transcription, a messenger RNA (mRNA) molecule is synthesized from a specific DNA region which is referred to as a gene. Subsequently, the mRNA leaves the cell nucleus through the nuclear pores of the nuclear membrane and travels to the ribosome, where this sequence serves as template to synthesize a protein, in a process known as translation. Within the ribosomes, triplets of consecutive RNA nucleotides called codons bind to complementary RNA nucleotides (called anticodons) of the transfer ribonucleic acids (tRNAs). Each tRNA attaches a specific amino acid that corresponds to its anticodon sequence, which is then added to the nascent polypeptide chain.

Explain how tomatoes grown and typically prepared as a dish below?? need it noww!༼ つ ◕◡◕ ༽つ

grandymaker [24]

Tomatoes are commonly grown from seedlings started indoors that are later transplanted into the garden. Tomato seeds are commonly planted indoors as early as 8 to 6 weeks before the average date of the last spring frost. Tomato seedlings are usually transplanted into the garden 1 to 3 weeks after the last frost. Wash tomatoes under cool running water.

Slice an "X" on the bottom of each tomato with a small utility knife. In a large saucepan bring water to a rolling boil. Fill a large mixing bowl with ice cold water. With a large spoon, place tomatoes in boiling water for 30 seconds to loosen skin. Remove tomatoes after 30 seconds, place directly into cold water to stop the cooking process. Core the tomatoes by removing the stem with a paring knife. Peel away the skin, being careful not to injure the flesh of the tomatoes.
