explain why myelinated is faster than unmyelinated
The structure of a typical neuron has a Myelin sheath (myelin is produced by the Schwan cell, in the peripheral nervous system), in the axon area, also certain points called along the axon are called nodes of Ranvier, these are, small unmyelinated areas. When action potentials occur in a neuron, only happen in the nodes of Ranvier (unmyelinated areas). This exact mechanism, saltatory conduction, is made possible by the presence of myelinated areas what makes that the action potential propagates faster than it would in a un unmyelinated axon.
Color code: Yellow are the myelinated areas, and the orange dots between them are the nodes of Ranvier
The information in DNA is coded in its sequence. Which of the following correctly describes the relationship between a change in the sequence of a cell's DNA, the proteins produced by that cell, and the function of the body tissue that the cell is part of? A. A change in the sequence of a cell's DNA can change the structure and function of the proteins produced, which can affect the proper functioning of the body tissue. B. A change in the sequence of a cell's DNA will always change the structure and function of the proteins produced, and will cause the function of the body tissue to improve. C. A change in the sequence of a cell's DNA does not change the structure or function of proteins, but will cause the body tissue to stop functioning. D. A change in the sequence of a cell's DNA can alter the structure and function of proteins, but does not have an effect on the function of the body tissue.
A mistake in DNA sequence is called missence mutation that results in an incorrect amino acid fused into a protein. Due to such changes which the ribosome will know will result in a peculiar amino acid codon. It will cause the protein to be deficient in its function.
Answer - Option A
Answer:
A
Explanation:
Option A correctly describes the relationship between a change in the sequence of a cell's DNA, the proteins produced, and the function of the body tissue. DNA carries the genetic information that determines the sequence of amino acids in proteins. When there is a change or mutation in the DNA sequence, it can alter the structure and function of the proteins produced by the cell. Since proteins play crucial roles in various cellular processes and functions, any change in their structure can have significant effects on the proper functioning of the body tissue.

Which type of limiting factor tends to more frequently cause abrupt shifts in a population? Question 12 options:density-dependent limiting factordensity-independent limiting factor
To answer this question we need to remember how each type of limiting factor works. In the case of Density-dependent limiting factors, we have that generate that the individual growth rate change with population size (logistic growth), these factors affect the growth rate per capita, and decreases as population increase, some examples are predation or parasites. Meanwhile, Density-independent limiting factors, affect the individual growth rate regardless of the population size, that is to say, the population size is not regulated by these mechanisms, in consequence, they can cause abrupt and erratic shifts in population size, some examples are earthquakes, floods, etc. Therefore we can say that the correct answer is density-independent factors.

The Smiths have satisfied their need for safety in accordance with Abraham Maslow's hierarchy of needs.
Human motivation can be explained with the help of various psychological theories. Abraham Maslow's hierarchy of needs is one such theory which tries to define human behavior on the basis of several needs which can be organized in a hierarchical order. The need for safety comes after the physiological needs in the hierarchy.
The need for safety arises only when the basic physiological needs ( air, thirst, hunger, etc.) are fulfilled. The need for safety translates a person's need to be free from any kind of threat or danger in their surrounding environment.

What specific molecules, found in some cells but not others, would allow them to activate different genes? Hint: think about what was different in how you activated gene 1, gene 2, and gene 3 in the first part of the simulation
Specific molecules found in one cell have a regulatory function, those regulatory molecules can be activator proteins that bind to the regulatory sites of the DNA acting as a on/off switches in the process of transcription, since the RNA that will be formed can be translated into different amino acid sequences. The CRISPR-Cas9 system is a example of gene expression supressor and activator used in molecular biology as a gene edit tool. The process of gene activation start when a transcription factor (protein) bind to bits of the DNA (that are marked by a promoter), the sequence marked is transcribed into a molecule of mRNA, this RNA will be translated in the cytoplasm into a animo acid sequence that will form a protein, being that protein from the gene "selected" and "marked" by the transcription factors. Each cells have they transcription factors, and the moment that they are triggered to work by an intracellular or extracellular stimulus.

What is ATP and why does it have stored chemical energy? What important polymer will you find adenosine monophosphate in (take note of what is attached to carbon #2)
ATP is an adenosine triphosphate, the energy-carrying molecule found in the cells of all living things. ATP works as a shuttle, capturing energy from the breakdown of food and transferring it to the parts of the cell that require energy to run their processes.
ATP has stored chemical energy in the pyrophosphate bond, which lies between the last two phosphate groups of ATP. When the cells need energy to do any work, ATP cleaves the third phosphate group, releasing a large amount of energy stored in the bond between the third and second phosphate group. Energy is required for all the cell’s activities. This includes visible activities, such as muscle movement when running or talking, as well as those that cannot be seen by the human eye, such as the nerve impulses involved in thinking or feeling. ATP provides energy for all these processes.
The important polymer where adenosine monophosphate is found is RNA. Adenosine monophosphate (AMP) is one of the components of RNA.

How the covid-19 and omicron viruses affects the peripheral nervous system .
Coronaviruses have been shown to spread back along the nerve from the peripheral nerve endings, across the synapses, and thus enter the brain, in several small animal studies. This is facilitated by the presence of a pathway for endocytosis or exocytosis between neurons of the motor cortex, and another secretory vesicular pathway between neurons and satellite cells.
Fast axonal transport occurs by employing axonal microtubules, allowing the virus to reach the neuronal cell body by a retrograde version of this mechanism.
Possible olfactory route spread is signaled by the occurrence of isolated anosmia and ageusia. In such a case, the virus could cross the cribriform plate to enter the central nervous system (CNS) from the nose. However, newer unpublished research suggests that olfactory neurons lack ACE2, while cells in the olfactory epithelium do. This could mean that viral injury to the olfactory epithelium, and not to the olfactory neurons, is responsible for anosmia, but further studies will be required to confirm this.

Genes A, D, and E are on the same chromosome. The crossover frequency between D and E is 0.30, between A and E is 0.17, and between D and A is 0.13. Which two genes are farthest apart?
Genes D and E are farthest apart on the same chromosome.
The value of crossover frequency between genes D and E is the highest, therefore, these two genes lie furthest apart on the same chromosome. As a general principle, the probability of a crossover between two particular genes is directly proportional to the distance between them. In other words, it can be said that the larger the value of the crossover frequency between two genes, the greater is the distance between them.
The unit centimorgan (cM) is generally used to estimate the distance between genes. One centimorgan is equal to hundred times the crossover frequency.

Social life is not complete without social difficulties. The term "social problem" refers to social circumstances, procedures, societal norms, or behaviors that are typically regarded as undesirable, detrimental, or endangering a number of values or interests, including social cohesion, the upholding of law and order, morality, the stability of social institutions, economic prosperity, or individual liberties. A social issue can also be perceived as a sense of collective guilt brought on by a failure to eliminate or improve certain unfavorable social situations that have a detrimental impact on particular segments of society.
Therefore, there is no presumption of value- or attitudinal neutrality in perception, interpretation, or intervention in this description of social issues. This specific characteristic distinguishes social phenomena that are seen to be social issues from other social or physical phenomena or situations that are thought to be difficulties tout court and that are possibly considered as not quite desirable or pleasant but without an element of threat.
