Answer:
Based on their roles, the neurons found in the human nervous system can be divided into three classes: sensory neurons, motor neurons, and interneurons.
Explanation:
Neurons are classified functionally according to their direction. The nerve impulse travels relative to the receiving neuron.
What do you mean by Neurons?Neurons may be defined as nerve cells that are responsible for the transmission of signals from the body to the brain.
Afferent neurons are the neurons of the sensory nervous system. They are responsible for conducting nerve impulse input from both somatic sensory and visceral sensory receptors. Most sensory neurons are afferent neurons.
Efferent neurons are the neurons of the motor nervous system, conducting nerve impulse output from the central nervous system to the effectors. All motor neurons are efferent neurons.
Interneurons or associated neurons lie entirely within the central nervous system. They receive stimulation from many other neurons and carry out the integrative function of the nervous system. The most numerous types of neurons are interneurons.
Therefore, it is well described above.

Pls help me
Answer:
it was
Explanation:
The correct answer is B. Cellular respiration supplies energy to cells, but photosynthesis does not.
Which statement is correct?Photosynthesis and cellular respiration are two distinct processes that occur in living organisms, particularly plants. Here's a brief explanation of each process:
Photosynthesis: Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy from the sun into chemical energy in the form of glucose. It occurs in the chloroplasts of plant cells. The process involves the absorption of carbon dioxide (CO2) and the release of oxygen (O2) as a byproduct. Photosynthesis is responsible for converting solar energy into stored chemical energy.
Cellular respiration: Cellular respiration is the process by which cells break down glucose and other organic molecules to release energy in the form of ATP (adenosine triphosphate). It occurs in the mitochondria of cells, including plant cells. During cellular respiration, glucose and oxygen are consumed, and carbon dioxide and water are produced as waste products. This process provides energy for various cellular activities.
Given the descriptions above, option B is the correct statement. Cellular respiration supplies energy to cells through the breakdown of glucose, while photosynthesis is the process that converts light energy into chemical energy and produces glucose.

A suspension of yeast cells is being grown under anaerobic conditions such that glucose is degraded to ethanol and carbon dioxide. To follow this process by monitoring the release of CO214, at which positions in the glucose molecule would the C14 label need to be incorporated
Answer:
carbons 3 and 4
Explanation:
Alcoholic fermentation is an anaerobic (non-oxygen-requiring) pathway capable of converting one mole of glucose (C6H12O6) into two moles of ethanol (C2H5OH) and two moles of carbon dioxide (CO2), producing during this process two moles of ATP. The overall chemical reaction is as follow: C6H12O6 (glucose) >> 2 C2H5OH (ethanol) + 2 CO2. During this process (fermentation), energy is obtained from the glycolysis process by which each glucose molecule is broken down into two pyruvate molecules (2 CH3COCOO−). Pyruvic acid is an organic acid that ionizes to produce a hydrogen ion and a molecule of pyruvate. Subsequently, this pyruvate is then converted into ethanol and CO2, generating NAD+, i.e., the oxidized form of nicotinamide adenine dinucleotide or NAD, which is required for glycolysis (and therefore to produce ATP). Moreover, dismutation refers to the redox reaction by which one compound with an intermediate oxidation state converts into two compounds. In consequence, the CO2 generated during fermentation arises from the dismutation of pyruvic acid. During this process, the major source of CO2 is carbon 3 (C3) and carbon 4 (C4) of the glucose as a result of the dismutation of pyruvate, and thereby these positions in the glucose molecule would the C14 label need to be incorporated.

Rabbit City has a rising population of 500,000 robust, fertile males and 450,000 robust, fertile females. If there were 4,000 live births, 3 fetal deaths and 40 maternal deaths, what is the birth rate
Answer:
The correct answer is 4.2105.
Explanation:
The birth rate is the period of the total number of individuals with live births per 1,000 population divided by the length of the period in years.
Birth rate = (live births/total population)*1000
= 4,000/950,000 x 1,000
= 4.2105
Thus, the correct answer is 4.2105.
g An Hfr strain is produced when Select one: A. an F episome is transferred to a new cell. B. an F episome leaves the E. coli chromosome. C. an F episome leaves the host chromosome and removes some of the host chromosome. D. an F episome integrates into the E. coli chromosom
Answer:
A. an F episome is transferred to a new cell.
Explanation:
Hfr strains arise from the integration of the plasmid into the bacterial cell in one of several ways such as the recombination of events. Most commonly are formed by the UV-induced integration of E coil F factor. It tries to transfer a copy of the F factors as well the entire chromosome to the recipient bacterium.Out of 800 progeny of a three-point testcross (testcross for a heterozygote for all three loci) there were 16 double crossovers, whereas 80 had been expected on the basis of no interference (Hint: each double CO produces two double recombinants).

Respuesta corta: Produciendo un sentimiento de satisfacción.
Explanation
En el texto se hace referencia a una investigación para analizar la relación entre las redes sociales y el cerebro de los adolescentes. Para ello los investigadores utilizaron imágenes magnéticas del cerebros de los 32 adolescentes estudiados. Una vez terminaron el estudio se dan cuenta que "una estructura del cerebro, llamada núcleo accumbens, se activa más cuantos más likes tuviera una imagen". Además, el autor del texto agrega que "Esto es interesante si se tiene en cuenta que este órgano nervioso es el responsable de que experimentemos momentos de placer intensos al ganar un premio, comer helado, etc". De acuerdo a lo anterior se puede interpretar que las redes sociales influyen en el cerebro de los adolescentes debido a que produce en ellos un sentimiento de satisfacción o reconocimiento a recibir "likes" de otras personas. Además, este sentimiento se puede interpretar como aprobación por parte de las demás personas.

Osteology 1) For the following fill-in the correct anatomical term: (ex. Inferior, superior, posterior, etc.) a. Your knee is ____________ relative to your navel. b. Your sternum is _____________ relative to your right side.
Answer:
a. inferior
b. medial
Explanation:
There are three planes that are used to divide the human body: 1-transverse plane, which is a horizontal line that divides the body into a superior (above) section and an inferior (below) section; 2-median sagittal plane, which is a vertical line that divides the body into equal left and right portions; and, 3-coronal plane, which divides the body into a ventral (anterior) section and a dorsal (posterior) section. As its name indicates, inferior is the opposite term of 'superior' and refers to a structure that is 'below' something else (for example, the feet are inferior to the head). Moreover, a medial structure refers to a structure that is closer to the midline of the body, and therefore divides the body into equal right and left sections (for example, the nose is medial to the eyes).
What contributes to cell membrane fluidity? Proteins and lipids exist as separate but loosely attached molecules that can move around Protein enzymes create the fluidity. The cell is bathed in water. The transport of substances through the membrane makes it fluid.
Answer:
Proteins and lipids exist as separate but loosely attached molecules that can move around
Explanation:
Cell membranes are mainly composed of lipids, proteins, and also carbohydrates. Phospholipids are the most abundant type of lipid and the main constituent of the cell membranes. Membrane proteins are divided into two types according to their interactions with the cell membrane: 1-integral (intrinsic) and peripheral (extrinsic) proteins. These peripheral proteins are loosely attached by ionic bonds or calcium bridges with the phosphate heads of the phospholipids; whereas integral membrane proteins contain side chains that interact with fatty acyl groups of the phospholipids. Cell membrane fluidity indicates how easily lipids (e.g., phospholipids and cholesterol) and proteins (e.g., intrinsic proteins) diffuse laterally in the cell membrane. This fluidity is affected by the amount of cholesterol, temperature, and the ratio of unsaturated to saturated fatty acids. Saturated fatty acids have no double bonds in the hydrocarbon chain, whereas unsaturated fatty acids have at least one double bond (these double bonds increase fluidity). Moreover, higher temperatures increase membrane fluidity, whereas cholesterol molecules function to regulate membrane fluidity: at high temperatures cholesterol molecules stabilize the membrane, whereas at low temperatures intercalate between phospholipids, thereby preventing them from clustering together.
