Transverse myelitis is an inflammatory disease of the nervous system involving the roots of the spinal nerves.
Overview - Transverse myelitis
It is a neurological disorder that damages the myelin sheaths of neurons in the spinal cord. This results in the interruption of the transmission of signals through the neuron. This results in extreme pain, weakness of muscle, sensory impairment, bowel and bladder dysfunction, paralysis, etc.
Symptoms
Symptoms can be exhibited on both sides of the body below the affected region of the spinal cord or on one side. Typical symptoms include,
Pain
Abnormal sensation
Weakness of arm and leg muscles
Bladder and bowel dysfunction
Causes
Infections can trigger transverse myelitis. Viruses (Herpes, Epstein-Barr, HIV, West Nile Zika, Hepatitis-B, etc), bacterial diseases (syphilis, tuberculosis, tetanus, etc), inflammations (such as multiple sclerosis, autoimmune disorders, etc) can cause transverse myelitis.
When to visit the doctor
See the doctor as soon as possible as the condition can worsen over time. Proper diagnosis is key as some other neurological disorders can also exhibit similar symptoms.

Evolutionary adaptations for survival on land produced tetrapods, which later evolved into _____________________________.
Evolutionary adaptations for survival on land produced tetrapods, which later evolved into amphibians, reptiles, and mammals.
Evolution: It can be defined as a natural phenomenon that involves the modifications in physical, biological, and metabolic characteristics of any species which get inherited from one generation to another resulting in better, more advanced new forms of species. This is a very slow process that usually took millions of years to establish a new species from a preexisting one.
The evolution of tetrapods started in the devonian period at around 400 million years ago which are kept under superclass tetrapoda which includes amphibians, reptiles, bird and mammales. The body plan, breathing plan, navigating plan all evolved with time and the tetrapods gets cherecterised into amphibians, reptiles, and mammals.
These facts were estabilished by the transitional fossils collected in late 20th century which are tested and studied on the basis of modern phylogenetic analysis.

Answer:
Vesicles that contained self-replicating RNA grew, split, and passed their RNA to daughters.
When a neuron is activated by a stimulus, its plasma membrane will change until it reaches a membrane potential of about 40 mV. What is special about this value
Answer: It is approximately the membrane potential at which the electrochemical gradient for Na+ is zero.
Explanation:
The charge in plasma membrane occurs with diffusion and electric fields.
For example, if there are two solutions, let's assume solution X and Solution Y are separated by a porous barrier (to diffuse in equal proportions).
The fundamental principle of diffusion states that solution from a high concentration diffuses to a lower concentration.
For instance, if the X solution contains 40 sodium ions and 40 chloride ions, the Y solution only has 30 sodium and 30 chloride ions. Due to the diffusion, these two solutions will mix and reach a steady-state.
The like charges repel, and opposite charges attract.
What does happen with a human body after death?
Answer:
Once the heart stops beating, that means the blood in the body is no longer circulated, meaning that gravity starts to do its work. The blood starts to pool (liver mortis) at the bottom of wherever the body was positioned (which can help indicate if a body has been moved since they died in homicide cases etc.), and the body starts to turn that green-ish blue color, with a dark-purpley color forming at the bottom of wherever gravity takes it (for example, if the body died and remained in a position standing up, then the blood would pool at the feet, whereas if the body died and remained laying on its back, then the pooling would occur in the back area of the body). Additionally, rigor mortis (you can remember it as being rigid) occurs, which is when the body locks up, so the joints lock and are unable to move, which is why it is often hard to get rid of/pack up and throw away a body because over the span of several hours the body locks up (it eventually wears off). Lastly, we have algor mortis, which is the change in temperature of the cadaver. Since the blood is no longer circulating, the body has nothing to retain a constant temperature anymore. The body will begin to change the temperature accordingly based on the surrounding temperature (environments that are hotter than the body will heat it up and similarly to cooler environments). If the body is found before it reaches the local temperature, then the current temperature can be used to help estimate and determine the time of death (there is a formula for this, but I'll leave it up to you if you want to look into it). After a few days, the body will start to decompose, and it will inhabit insects, especially flies and such, and the stage of development of the larvae and/or fly can also help estimate and determine the time and date of death.

During the complete catabolism of a molecule of glucose by aerobic cellular respiration, oxidative phosphorylation accounts for how many times more ATP than does substrate-level phosphorylation
About 4 times more ATP is generated during oxidative phosphorylation than substrate-level phosphorylation.
Oxidative phosphorylation:In the metabolism process known as oxidative phosphorylation, also known as electron transport-linked phosphorylation or terminal oxidation, cells employ catalysts to oxidize carbohydrates, liberating chemical energy and producing adenosine triphosphate (ATP) as a consequence.
According to some modern studies, the ATP output after aerobic respiration is only approximately 30-32 ATP molecules /molecule of glucose, rather than 36-38, because:During oxidative phosphorylation,
the ATP: NADH+H+ and ATP: FADH2 ratios appear to be 2.5 and 1.5 instead of 3 and 2, respectively. Substrate level phosphorylation:Substrate-level phosphorylation is a metabolic activity that produces ATP or GTP by the direct transfer of a phosphoryl (PO3) group from another phosphorylated chemical to ADP or GDP.Substrate level phosphorylation happens via glycolysis and the Krebs cycle. It happens in two phases during glycolysis, and because 2 molecules are involved, it eventually creates 4 ATP from a glucose molecule.As a result, the total ATP molecules generated from substrate-level phosphorylation of a glucose molecule during aerobic respiration will be 4+2 = 6.Therefore, it is concluded that ATP generated during oxidative phosphorylation is 30-6=24 or 32-6=26 i.e., about 4 times than substrate-level phosphorylation.

Iron released from hemoglobin is transported through the blood by ______________ to the ______________.
Iron released from hemoglobin is transported through the blood by transferrin to the bone marrow.
Transport of Iron
The cellular iron homeostasis is controlled by the iron and heme transport proteins. They work with chaperones, ferrireductases, and ferroxidases which guide the movement of iron within and in & out of the cells. In the blood, the ion released from the hemoglobin molecule is bound to the transport protein transferrin which carries the iron into the bone marrow. Inside the bone marrow, the iron is delivered to the precursors of RBCs, the erythrocyte progenitor cells. Inside the bone marrow, the heme units in the EPC take up the iron to which oxygen will bind as they become mature RBCs. The flow of iron in the blood plasma is controlled by the protein hepcidin whose production is positively influenced by transferrin in the plasma. In the case of damaged RBCs, they are processed by the macrophages of the spleen, liver, and bone marrow which releases the iron molecule.

How do vaccines work if the pathogen in them is dead?
A. The immune system holds on to the dead pathogen from the vaccine, and if you are infected again, the new pathogen recognizes the dead
form of itself and becomes inactive so that it is not killed as well.
B. It causes antibodies to be generated that take the form of the pathogen, so the next time it is encountered, the antibodies make the pathogen
think the body is friendly and not a target.
C. It causes memory cells to be generated so that next time the pathogen is encountered the immune response is very fast, killing the pathogen
before it can do any harm.
D. The vaccine alters your body chemistry so that whichever pathogen you are vaccinated against cannot even enter your body in the first place.
Answer:
B
Explanation:
Vaccination is the conferring of immunity to an individual by artificial means. A vaccine can be in the form of weakened or dead disease causing micro organisms. In the body, the dead pathogens stimulate the production of specific antibodies by the body such that next time the body gets infected by the actual pathogens, there will be no serious illness caused.

When O2 binds to heme in hemoglobin, the Fe3+ ion is drawn into the plane of the Porphyrin causing a conformational change that is transmitted to adjacent subunits enhancing the affinity for additional O2 binding.
Oxygen binds to the iron inside the heme, forming an octahedral iron complicated. This form is referred to as oxyhemoglobin; the form without the sure oxygen is known as deoxyhemoglobin. masses of exciting matters occur as a result of oxygen binding, structurally speaking, initially, the heme adjustments form.
Hemoglobin can be the concept of a tetramer made from alpha-beta dimers.
