a. extrafusal fibers; Golgi tendon organs b. intrafusal fibers; extrafusal fibers
c. Golgi tendon organs; intrafusal fibers d. motor neurons; intrafusal fibers
e. multiunit fibers; myofibrils
Answers
Muscle tension is sensed by extrafusal fibers, whereas muscle fiber length is sensed by Golgi tendon organs.
Extrafusal muscle fibers are the muscle fibers that generate tension and produce movement. They are innervated by alpha motor neurons and are responsible for muscle contraction. Muscle tension is sensed by these fibers.
Golgi tendon organs are specialized sensory receptors located in the tendons of muscles.
They are responsible for sensing changes in muscle tension and provide information to the central nervous system to regulate muscle contraction.
They sense muscle fiber length and are responsible for the protective reflex that causes muscles to relax when tension becomes too great.

Muscle tension is sensed by Golgi tendon organs, whereas muscle fiber length is sensed by intrafusal fibers.
Golgi tendon organs are sensory receptors located within tendons that are sensitive to changes in muscle tension. They signal the central nervous system to adjust muscle tension in response to changes in load.
Intrafusal fibers are specialized muscle fibers located within muscle spindles, which are sensory receptors that detect changes in muscle fiber length. These muscle fibers are distinct from the larger, more common extrafusal muscle fibers that generate force and movement.
Muscle spindles are specialized sensory organs located within skeletal muscle that detect changes in muscle fiber length and velocity of stretch. The muscle spindle consists of several intrafusal muscle fibers, which are innervated by sensory nerve fibers known as primary afferents. These fibers wrap around the central region of the intrafusal muscle fibers, known as the equatorial region, and are sensitive to stretch.
When a muscle is stretched, the intrafusal fibers within the muscle spindle are also stretched, which causes the primary afferents to fire and send signals to the spinal cord. These signals are then relayed to motor neurons, which stimulate the extrafusal muscle fibers to contract and resist the stretch. This is known as the stretch reflex and helps to maintain muscle tone and joint stability.

The process of_________________in populations over time that makes descendants__________________from their___________
Answers
The process of evolution occurs in populations over time which makes descendants different from their ancestors.
Evolution is a gradual process of genetic change and adaptation that occurs over generations. It is driven by various mechanisms such as natural selection, genetic drift, gene flow, and mutations. These mechanisms can lead to changes in the frequency of alleles (versions of genes) within a population, resulting in the emergence of new traits or the disappearance of old ones.
Over time, these changes can accumulate and lead to the formation of new species that are distinct from their ancestors. Evolution is a fundamental concept in biology that provides a framework for understanding the diversity of life on Earth. It explains how organisms have adapted to different environments and how they are related to one another through common ancestry.

the influence of polymer structure on the interactions of cationic polymers with dna and morphology of the resulting complexes
Answers
The influence of polymer structure on the interactions of cationic polymers with DNA and the morphology of the resulting complexes has a significant effect on the delivery of nucleic acids into cells. The type of cationic polymers and their concentration, the polymer structure, molecular weight, and degree of branching, as well as their interactions with DNA, all play a significant role in the formation and stability of the resulting polyplexes.
The morphology of polyplexes varies with polymer type and architecture, and this plays a vital role in gene delivery's efficacy and toxicity.
Among the most extensively investigated polymers are linear poly(ethyleneimine) (PEI), branched PEI, and poly-L-lysine (PLL).
PEI is a highly branched cationic polymer with primary, secondary, and tertiary amines, making it an efficient gene delivery vector.
In addition to PEI, PLL has been extensively investigated as a gene carrier.
It is a cationic polymer with lysine residues that can interact with negatively charged DNA.
Polymer concentration, molecular weight, degree of branching, and degree of protonation are all critical variables affecting the morphology of the polyplexes.

consider the total breakdown of the glycogen structure below. assuming each glycosidic linkage can be broken down completely and the resulting products are fed through glycolytic metabolism.
Answers
The complete breakdown of glycogen structure results in the production of glucose molecules.
Glycogen is a complex carbohydrate composed of many glucose units linked together by glycosidic bonds. During the breakdown of glycogen, each glycosidic bond is cleaved by the action of glycogen phosphorylase, releasing a single glucose molecule.
The breakdown of glycogen occurs through the action of the enzyme glycogen phosphorylase, which cleaves the glycosidic bonds and releases individual glucose molecules. These glucose molecules can then be used as a source of energy for the body through cellular respiration.
Once the glucose molecules are produced, they can be fed into the glycolytic metabolism pathway, which results in the breakdown of glucose into pyruvate. This process generates energy in the form of ATP and is an important source of energy for the body, particularly during intense physical activity.

which statement about n-linked glycosylation is correct (in eukaryotes)? a. n-linked sugars are attached to proteins as a 14 residue oligosaccharide during translation in the endoplasmic reticulum. b. n-linked sugars are attached to proteins as a 14 residue oligosaccharide during translation in the cytoplasm. c. n-linked sugars are attached to proteins as a 14 residue oligosaccharide after translation in the golgi apparatus. d. n-linked oligosaccharides are attached to proteins one sugar at the time in the golgi apparatus.
Answers
The correct statement about n-linked glycosylation in eukaryotes is c. N-linked sugars are attached to proteins as a 14 residue oligosaccharide after translation in the golgi apparatus.
N-linked glycosylation is a process that involves the addition of a sugar molecule, specifically an oligosaccharide, to a protein. This process occurs in eukaryotic cells and is one of the most common post-translational modifications that occur in proteins.
The process of N-linked glycosylation begins with the synthesis of the oligosaccharide chain in the endoplasmic reticulum (ER). This chain is then transferred to a specific amino acid residue (asparagine) on the protein in a process known as "en bloc" transfer. The protein is then transported to the Golgi apparatus where it undergoes further processing and modifications.
Once the protein reaches the Golgi apparatus, the oligosaccharide chain is further modified. It is trimmed down to its final size of 14 residues and then attached to the protein. This process is called "maturation" of the oligosaccharide chain. The final product is a protein with a fully matured, 14 residue oligosaccharide chain attached to it.
Therefore, the correct statement about N-linked glycosylation in eukaryotes is c. N-linked sugars are attached to proteins as a 14 residue oligosaccharide after translation in the Golgi apparatus. Option a is incorrect because the 14 residue oligosaccharide is synthesized in the ER but attached to the protein in the Golgi. Option b is incorrect because the process of N-linked glycosylation occurs in the ER and Golgi, but not in the cytoplasm. Option d is incorrect because the oligosaccharide is not attached to the protein one sugar at a time, but rather as a fully matured, 14 residue chain.
The correct statement about N-linked glycosylation in eukaryotes is: a. N-linked sugars are attached to proteins as a 14 residue oligosaccharide during translation in the endoplasmic reticulum.

List the 3 Parts of the Modern Cell Theory
Answers
Answer:
1. All organisms are made of cells
Cells are the smallest unit of life. Each cell is a membrane of semi-permeable phospholipids wrapped around cytosol or a solution of water and dissolved solutes. All cells rely on DNA to hold the information necessary to produce the molecules they use to obtain energy. Although the methods for obtaining energy vary widely, all organism obtain energy to grow and reproduce. This first tenet of the cell theory is mostly true, but the discovery of viruses lead to complications. Viruses, while they use DNA or RNA to reproduce, do not have cells or cellular membranes. Viruses typically use a host cell to replicate. In this case, the virus appears to be living, but does not create its own cell. Some scientist argue that viruses are not living, thus cell theory is not violated.
2. Cells are the most fundamental unit of life
Organisms can be single cells, which hold all of the components necessary for a metabolism, or they can be more complex. More complex organisms divide the various metabolic tasks into different groups of cells, called tissues. These tissues are arranged in compartments with membranes that separate them from other tissues. These groups of tissues are called organs. A group of organs functioning together is an organism, or an individual creature. Each cell is distinct from the cells next to it, and each functions independently, while contributing to the output of the organism as a whole. Again, modern cell theory is a bit more complicated because advances in science have revealed many different organelles within cells. These organelles are bound in membranes themselves, and serve different functions for eukaryotic cells. Some scientists argue that these are more fundamental units, but other scientists argue that like an organ outside of an organism, they could not function without the cell.
3. Cells come from other cells
As far as we know, no cell on Earth currently has arisen spontaneously. All cells are the result of cell division. When a cell is large enough, it replicates its DNA and important components. These components can then be divided into two daughter cells, which are copies of each other. Variations in the DNA in each cell can lead to changes in how they function, which can result in them dividing at different rates. The cell that reproduces more than the other cell will pass on more of its DNA. The purpose of every cell or organism is to reproduce the DNA in cells.
This third tenet of the cell theory has yet to be disproven. No scientist has ever created a functioning cell without replicating another cell, although some scientists are trying. If they were successful, it would give proof to how life could have evolved. It is thought that a self-replicating molecule mutated, developed the ability to produce a membrane, and thus the first cell was born. The cell was such a successful form of life that all life since has used the same basic template.
The parts of the modern cell theory are:
All living things are made up of at least one cellCell is the basic and fundamental unit of lifeAll cells arise from pre-existing cellsCELL THEORY:
Cell theory is a universally accepted theory that explains the features of life in three statements.The cell theory was composed in 1890's by three scientists namely: Rudolf Virchow, Mathias Scleiden and Theodor Schwann.

The biological theories of obsessive-compulsive disorder (OCD) have primarily focused on a circuit in the brain known as the cortico-striato-thalamo-cortical (CSTC) circuit. This circuit involves several key regions of the brain, including the prefrontal cortex, basal ganglia, and thalamus.
In individuals with OCD, there appears to be dysfunction within this circuit, leading to difficulties with inhibitory control and the development of compulsive behaviors. Specifically, there is evidence that the basal ganglia are overactive in individuals with OCD, leading to the development of repetitive, compulsive behaviors. Additionally, there may be abnormalities in the neurotransmitter systems involved in this circuit, such as serotonin and dopamine.
Overall, while there is still much to be understood about the neurobiological underpinnings of OCD, the CSTC circuit appears to play a critical role in the development and maintenance of this disorder.
