Impulse conduction is fastest in neurons that a. Myelinated

The nervous system is the coordination system in charge of controlling all body activities after receiving impulses and manipulating them. Impulse is a stimulus in the form of an electric current that is forwarded to the spinal cord.

The mechanism of impulse transmission occurs by conduction which involves the pumping of Na+ and K+ ions through a semipermeable membrane.

The part of the nerve cell that transmits stimuli is the neuron where in the long part, namely the axon, there is a myelin sheath which functions to accelerate stimulation. When action potentials occur, myelin speeds up the transmission of nerve impulses by assisting in charge jumping. The speed of conduction of an impulse will increase in direct proportion to the increase in the diameter of the nerve.

The velocity of blood flow is lowest in capillaries because: The total cross-sectional area of the capillaries is greater than the total cross-sectional area of the arteries or any other part of the circulatory system. The correct option is D.

Blood flow velocity and total blood vessel cross-sectional area are inversely related. The velocity of flow reduces as the vessels' overall cross-sectional area grows. The capillaries, where blood flow is the slowest, provide time for the exchange of gases and nutrients.

Therefore, "The overall cross-sectional area of the capillaries is greater than the total cross-sectional area of the arteries or any other portion of the circulatory system" is the right response.

40x magnifies the viewing field to reveal 583.33 distinct blood cells. Due to their rounded shape, blood cells may be recognized. They don't have cell walls as plant cells do.

At a total magnification of 40x (a scanning microscope), there may be counted 583.33 unique blood cells. The diameter of a 40x viewing field of view is 4200 m, whereas the normal size of a red blood cell is 6.2-8.2 m (7.2 m). So, 583.33 is the response.

Every fruit produces a particular amount of ethylene over the course of its lifecycle, and it is known as the "fruit-ripening hormone." However, when some fruits begin to ripen, their ethylene levels suddenly increase.

Most fruits contain a gaseous molecule called ethylene that starts the ripening process. Its level in under-ripe fruit is relatively low, but as fruit mature, they create higher amounts that speed up the ripening process or the stage of ripening known as the “climacteric.” The level of ethylene and rate of ripening is a variety-dependent process. Some apple types, like McIntosh, create astronomical levels of ethylene, which makes them difficult to store. They immediately soften and senesce in storage when harvested after the sudden surge in ethylene. Other types have a slower rise in ethylene and slower ripening rate.

Hence, ethylene molecule influence ripening by inducing changes over fruit covering.

Our total body weight accounts for about 7 to 8 % of blood. Blood is a mixture of around 55 percent plasma and 45 percent blood cells. Blood running through the veins, arteries and capillaries is called whole blood.

How does the blood change as it flows through the respiratory system?

Blood circulatory system, also called the cardiovascular system, delivers oxygen and nutrients to all the cells of the body.

The respiratory system consists of the respiratory passage and respiratory organ, that is the lungs.

Blood is carried to the lungs through the pulmonary arteries where it picks up oxygen. The blood then leaves the lungs and returns to the heart via the pulmonary vein. It then enters the left atrium. The blood then drops into the left ventricle through the mitral valve.

Transport of gases also occurs through blood.

For exchange or oxygenation, the deoxygenated blood is transported to the lungs from heart. Carbon dioxide is exchanged with oxygen as the blood flows through the respiratory system. For further circulation to various body parts, oxygenated blood is then transported to the heart.

Some amount of gases get dissolved in the blood plasma and get transported, whereas some amount of them is transported in the bound state.

So therefore, CO2 and oxygen bind with hemoglobin in RBC.

The two-neuron chain allows increased communication and control of the effector organ is true. The two neuron chain allows increased communications and control the effector organ. the cell bodies of the preganglionic neurons in the sympathetic division are located... Which of the following parasympathetic nerves controls the production of tears, nasal secretion and saliva.

1. The two-neuron chain begins with an afferent neuron, which is a sensory neuron that receives information from the environment. This neuron sends an electrical signal to an efferent neuron, which carries the signal to an effector organ such as a muscle or gland.

2. The signal from the afferent neuron triggers the efferent neuron to fire an action potential. This action potential carries the signal to the effector organ and triggers it to perform a specific action.

3. The effector organ then responds to the action potential by contracting or releasing chemicals as appropriate. For example, if the effector organ is a muscle, it will contract in response to the signal, while if the effector organ is a gland, it will release hormones or other chemicals.

4. The two-neuron chain allows for the communication and control of the effector organ to be more precise and efficient. By having two neurons involved in the communication process, the signal is more accurately transmitted, and the response is more quickly and accurately carried out. This allows for finer control of the effector organ, which can make it easier to achieve desired results.

As electrons are passed down the electron transport chain to the final electron acceptor, energy from the moving electrons transports hydrogen ions into the inter membrane space.

As electrons are passed down the chain, they move from a higher to a lower energy level, releasing energy. Some of the energy is used to pump H +start superscript, plus, end superscript ions, moving them out of the matrix and into the intermembrane space. This pumping establishes an electrochemical gradient.

Each electron donor will pass electrons to an acceptor of higher redox potential, which in turn donates these electrons to another acceptor, a process that continues down the series until electrons are passed to oxygen, the terminal electron acceptor in the chain. To oxygen, the final electron acceptor in the chain, electrons are transferred.

The fovea centralis, or fovea, is a small depression within the neurosensory retina where visual acuity is the highest. The fovea itself is the central portion of the macula, which is responsible for central vision.

The fovea is responsible for sharp central vision (also called foveal vision), which is necessary for humans for activities for which visual detail is of primary importance, such as reading and driving. The most devastating vision loss from a retinal disease often occurs when the fovea — a 1.5-millimeter pit in the central retina — is affected.
