Some drugs fundamentally influence one neurotransmitter or class of neurotransmitters. For instance, prescription opioids and heroin deliver impacts that are like (however more articulated than) those created by the neurotransmitters endorphin and enkephalin: expanded absence of pain, reduced readiness, and low breath. Different medications upset more than one sort of neurotransmitter. Cocaine, for instance, joins to structures that manage dopamine, prompting increments in dopamine activity and creating euphoria; it likewise delivers changes in norepinephrine and glutamate frameworks that cause stimulant impacts.

Shot in the head, the victim died instantly because the bullet entered the _______, the portion of the brain that regulates breathing.
Final answer:
The victim died instantly after being shot in the head because the bullet entered the medulla oblongata, a critical part of the brain stem that controls the unconscious act of breathing.
Explanation:
The bullet entered the medulla oblongata, the portion of the brain stem that regulates unconscious functions such as heart rate and breathing. The brain stem, specifically the medulla and the pons, contain respiratory centers that automatically adjust the rate of breathing according to the body's needs. For instance, during physical exercise when the blood's carbon dioxide levels rise, the brain stem signals the diaphragm to increase the rate of contractions, thus quickening the breathing rate to expel the excess carbon dioxide and maintain blood pH levels within a narrow range.
The control of breathing is critical for life, and this is why injuries that affect the brain stem, especially the medulla oblongata, can lead to immediate death, as they compromise the body's ability to regulate critical functions like breathing and heart rate.

The ______ _______ surrounds the nucleus and separates it from the cytoplasm.
The nuclear envelope surrounds the nucleus, separating it from the cytoplasm, and regulates the transport of molecules.
Explanation:The nuclear envelope surrounds the nucleus and separates it from the cytoplasm. The nuclear envelope, or nuclear membrane, is a double-layered structure that provides the nucleus - the cell's control center - with a barrier from the rest of the cell. This helps protect the DNA inside the nucleus and regulates the transport of molecules in and out of the nucleus through nuclear pores.
The primary role of the nuclear envelope is to compartmentalize the nucleus, creating a distinct environment for the genetic material (DNA) inside. This separation is crucial because it protects the DNA from potential damage that could result from various cellular processes occurring in the cytoplasm.

Chromosomes are lined up in the middle of the cell during which phase of mitosis?
During the metaphase phase of mitosis, the sister chromatids align along a linear plane called the metaphase plate in the middle of the cell. This setup facilitates the subsequent separation of chromatids.
Explanation:Chromosomes are lined up in the middle of the cell during the metaphase phase of mitosis. During this phase, the sister chromatids, connected by cohesion proteins, align along a linear plane called the metaphase plate or equatorial plane. This metaphase plate is positioned roughly midway between the two poles of the cell. The chromosomes are maximally condensed at this time, thereby preparing for separation during the next phase.

Facilitated diffusion is an example of _____.
passive transport
concentration gradient
active transport
osmosis
The answer in the space provided is passive transport. A passive transport occurs when there is a presence of ions or other substance moving through the cell without having any effort or means of having to use energy when passing or moving.
Facilitated diffusion is an example of passive transport. It's a type of passive transport that involves the movement of molecules across a cell's membrane using transport proteins, without the need for energy. It is different from active transport and osmosis.
Explanation:Facilitated diffusion is an example of passive transport. In Biology, passive transport is a process by which anions, ions, or molecules move along a concentration gradient, which is a difference in concentration across a space or a membrane, from an area of higher to lower concentration. No energy is needed in this process.
Meanwhile, facilitated diffusion is a type of passive transport that uses transport proteins to move other ions and small molecules across the plasma membrane. These proteins change shape as the molecules or ions are carried across the membrane, without any energy requirement. Active transport, on the contrary, requires energy to move particles against a concentration gradient, while osmosis specifically refers to the movement of water.

How has the Gila Monster adapted to the breeding patterns of its prey the Gambel quail and desert cottontail rabbits?
As the Gila monster consumes the eggs or young of the desert cottontail and Gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. However, for this, the Gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.
First, is that they possess huge bodies, and can consume greater concentrations of food during a small period. Secondly, they require to feed infrequently as they can accumulate fat in their tails. Ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
The Gila monster has adapted to the breeding patterns of its prey, the Gambel quail and desert cottontail rabbits, by using its fat tail as a storage depot for water.
Explanation:The Gila monster has adapted to the breeding patterns of its prey, the Gambel quail and desert cottontail rabbits, by using its fat tail as a storage depot for water. The dry climate where the Gila monster lives can make water scarce, so having a fat tail allows it to store water for long periods of time. This adaptation helps the Gila monster survive in its environment and ensure it has access to water even when its prey may not be abundant.

Phosphofructokinase is an allosteric enzyme that catalyzes the conversion of fructose 6-phosphate to fructose 1,6-bisphosphate, an early step of glycolysis. in the presence of oxygen, an increase in the amount of atp in a cell would be expected to _____.
In the presence of oxygen, an increase in the amount of ATP in a cell would be expected to inhibit phosphofructokinase.
Phosphofructokinase is a key regulatory enzyme in glycolysis, which is the metabolic pathway that converts glucose into pyruvate, generating ATP and NADH. The regulation of phosphofructokinase is crucial for maintaining energy balance within the cell.
ATP serves as an energy currency in the cell, and an increase in ATP levels signals that there is already an abundance of energy available. In this scenario, the cell does not need to produce more ATP through glycolysis.
Therefore, an increase in ATP concentration acts as a feedback mechanism to inhibit phosphofructokinase.
