Answer:
Neurotransmitters; neuromodulators; facilitation; an increased; an increased; inhibition; a decreased; a decreased.
Explanation:
In Biology, stimulus can be defined as an obvious change in either the chemical or physical structure of an organism' environment (either external or internal). Thus, all living organisms (both animals and plants) respond to changes in their environment and consequently, an appropriate response or reaction is made. Also, stimulus arising from within the organism is known as internal stimulus while those from its environment are known as the external stimulus.
In organisms, the specialized cells that detect stimulus are generally known as sensory receptors while a group of these receptors is referred to as sense organ.
Neuromodulation is the release of chemicals (other than neurotransmitters ) from cells that locally regulate or alter the response of neurons to neurotransmitters. The substances released are called neuromodulators. Neuromodulation generally results in either facilitation or inhibition. When there is greater response from a postsynaptic neuron because of the release of neuromodulators it is facilitation. This may result from either an increased amount of neurotransmitter in the synaptic cleft or an increased number of receptors on postsynaptic neurons. When there is less response from a postsynaptic neuron because of the release of neuromodulators, it is called inhibition. This results from either a decreased amount of neurotransmitter in the synaptic cleft or a decreased number of receptors on postsynaptic neurons.

In a population of cats, a gene that controls an observable trait has several different alleles. Which of the following best explains how genetic drift might affect the genetic makeup of this cat population over time?
It is a directed process, so it might cause an increase in the gene pool's allele frequencies.
It is a nonselective process, so it might cause an allele to disappear from the gene pool by chance.
It is a random process, so it might cause a population to reach genetic equilibrium.
It is a selective process, so it might cause an increase in the population's genetic variation.
Answer: It is a nonselective process, so it might cause an allele to disappear from the gene pool by chance brainliest?

why do you produce carbon dioxide when working out?
Answer: The lungs bring oxygen into the body, to provide energy, and remove carbon dioxide, the waste product created when you produce energy. The heart pumps the oxygen to the muscles that are doing the exercise. When you exercise and your muscles work harder, your body uses more oxygen and produces more carbon dioxide.

What do you think accounts for the higher risk of earthquakes in Los Angeles than in Chicago?
Answer:
Los Angeles, California, rests on a major (and active) fault line known as the San Andreas Fault. It's the line between the Pacific and North American tectonic plates, and more seismic activity is measured daily than on the New Madrid Fault, which runs through New Madrid, Missouri, and around the mid-west. Chicago is still at risk, of course, but not nearly as much, given the small activity of the fault line.
The San Andreas Fault, a significant (and active) fault line, runs through Los Angeles, California.
Why is a higher risk of earthquakes in Los Angeles?There is more seismic activity recorded there every day than on the New Madrid Fault, which passes through New Madrid, Missouri, and other midwestern cities.
It is the boundary between the Pacific and North American tectonic plates. Chicago is still in danger, of course, but not nearly as much as before due to the fault line's low level of activity.
Therefore, movement along the San Andreas Fault and its numerous accompanying faults, which define the tectonic border between the Pacific and North American tectonic plates, is what causes earthquakes in California.

Determine whether each statement correctly describes the myocardial action potential and the pacemaker potential. 1. Because the pacemaker potential occurs during systole, it can also be called systolic potential. (Click to select) 2. The pacemaker potential is the relatively slow, spontaneous depolarization in the SA node. (Click to select) 3. Myocardial cells produce their own action potentials after being stimulated by action potentials originating in the SA node. (Click to select) 4. Myocardial action potentials are characterized by a spike and then slow depolarization. (Click to select)
Answer:
1. False
2. True
3. True
4. False
Explanation:
In mammals, the contraction of the heart muscle is caused by pacemaker cells localized within the sinoatrial (SA) node. These cells rhythmically generate slow electrically-induced action potentials due to their slow rate of depolarization. The pacemaker cells generate the action potentials that propagate through the heart and trigger the contraction of myocyte cells (i.e., myocytes simply conduct the action potential waves). The slow depolarization of pacemaker cells occurs during diastole, i.e., during the period of relaxation of the heart muscle.

Male kangaroos that kick one another and bighorn rams will gather and crash their heads into each other prior to mating season are examples of competition.
What is competition?Competition is a type of ecological relationship in which two organisms contend for the same resource (e.g., food).
Competition can be divided into intraspecific competition and interspecific competition.In general, intraspecific competition makes reference to competence for reproduction.In conclusion, male kangaroos that kick one another and bighorn rams will gather and crash their heads into each other prior to mating season are examples of competition.

What is reflex arc?A reflex arc is a neural pathway that mediates a reflex action. It is a rapid and automatic response to a specific stimulus that does not require conscious thought or decision-making from the brain. When a sensory receptor in the body, such as the skin or muscles, is stimulated, a nerve impulse is transmitted to the spinal cord, where it is processed by an interneuron.
The interneuron then sends a signal through a motor neuron to the effector, such as a muscle, causing a rapid and involuntary response, such as pulling your hand away from a hot stove. This entire process occurs without conscious control from the brain, allowing for quick and protective responses to potentially harmful stimuli.

The ___________________________ is the current that spans the entire globe and forms in a large loop of circulating ocean water. This current is responsible for the balance of heat on Earth.
Answer:
ocean gyre
Explanation:
The ocean gyre may be defined as the large system of a circulating ocean currents that is formed as a result of wind patterns globally and by the forces created by the rotation of the Earth. It helps to create a large ocean conveyor belt that helps in circulating the ocean waters in the entire planets. Thus the ocean water keeps a check on the heat of the earth and maintains a balance of heat on the planet.
The ocean gyres makes the movement of the ocean water on the entire globe and thus forms a large loop of the circulating ocean water.

Can someone explain to me about how the pereodic table is used
Answer:
So basically the rows are called periods, and the columns are called groups. The groups show that those elements have similar characteristics. There are also different families such as the noble gases and alkali earth metals. The elements are placed where they are because of the atomic number which is directly equal to the number of protons there are. The atomic mass is the number of both protons and neutrons. Also, even though the number of protons can be equal to the number of electrons, that isn't always the case. It could be an isotope which is basically for when an element or atom isn't neutral.
