The production of red blood cells is regulated by a feedback loop involving erythropoietin. In non-disease states, the production of red blood cells is equal to the destruction of red blood cells, thus maintaining sufficient red blood cells to deliver adequate oxygen to the body's tissues. However, when the number of red blood cells decrease and oxygen levels are low, erythropoietin is produced by the liver and kidneys to increase the production of red blood cells. Is this a positive or negative feedback loop
Answers
Answer:
Negative feedback.
Explanation:
The production of erythropoietin by the liver and kidneys is a negative feedback because with the production of erythropoietin, our body tends to move to become more stable state. The erythropoietin is produced by the liver and kidneys to increase the production of red blood cells if the quantity of red blood cells are lower than the normal range. If the number of red blood cells are decreases the oxygen level in our body is low that leads to unstable condition of the body but when the concentration of red blood cells increases, the body move towards stability.

In the citric acid cycle when an aldol addition occurs in a biological system, how do the amino acids contained in the Citrate Synthase enzyme help facilitate the reaction
Answers
Answer:
Citrate Synthase facilitates the formation of citrate by deprotonating Acetyl CoA and by protonating the carbonyl oxygen of oxaloacetate
Explanation:
Citrate synthase is a key enzyme in the citric acid cycle that functions to catalyze the formation of citrate from oxaloacetate and acetyl-CoA: acetyl-CoA + oxaloacetate + H2O >> citrate + CoA-SH (Coenzyme A ). This enzyme contains three amino acids at its active site that work together to catalyze the conversion of acetyl-CoA and oxaloacetate into citrate. This active site acts by abstracting (deprotonating) a proton from the alpha carbon of Acetyl CoA which serves as the nucleophile. Subsequently, the active site of the enzyme also protonates the carbonyl oxygen of oxaloacetate, which then suffers nucleophilic attack and thereby facilitating nucleophilic substitution reaction.

Compare and contrast disorganized schizophrenia and paranoid schizophrenia.
Answers
Answer:
The paranoid subtype is characterized by the presence of hallucinations and delusions. In the disorganized one appears a behavioral disorganization and of the thought and language as well as an inappropriate affect. These patients tend to have an earlier onset, a worse prognosis, and a greater number of neurocognitive alterations.
Explanation:
Paranoid schizophrenics are characterized by sharp delusions, especially persecution ideas of grandeur, often with a corresponding aggressive reaction in response to the alleged persecution. There may be hallucinations of various kinds, to which patients react consecutively, but later, as deterioration occurs, apathy and indifference appear. Hallucinations are common. On the other hand, disorganized schizophrenia is another form of schizophrenia that is characterized by disorganization of speech, that is, the language is rambling and incoherent, the behavior is unpredictable, inappropriate and incongruous.
Answer:
The paranoid subtype is characterized by the presence of hallucinations and delusions.

How are spring tides different from Neap Tides. Give at least 2 reasons _______
Answers
Answer:
Seven days after a spring tide, the sun and moon are at right angles to each other. This produces moderate tides known as neap tides, meaning that high tides are a little lower and low tides are a little higher than average. Neap tides occur during the first and third quarter moon, when the moon appears "half full.

Mlorogla
Answers
Answer:
Astrocytes are the neuroglia, which help to regulate the reuptake of neurotransmitters from neural tissue.
Cell bodies of unipolar neurons are insulated from adjacent cell bodies by satellite cells.
The ventricles of the brain are lined with ependymal cells, which form an epithelial layer that is permeable to cerebrospinal fluid.
The macrophages of the Central Nervous System, which function to remove foreign microorganisms, are called microglia.
The myelin sheath of the Central Nervous System is formed by oligodendrocytes.
Axons of unipolar neurons are insulated by Schwann cells, which increase the speed of the electrical impulse.
Explanation:
The neuroglia cells are a group of specialized cells that are in the Central and Peripheral Nervous System.
Astrocytes are star-shaped cells that maintain homeostasis in the nervous tissue. They also are part of the blood-brain barrier controlling what can enter the brain and whatnot.
Satellite cells are in the Peripheric Nervous System. They are around neurons and provide nutrients and insulation to neurons.
Ependymal cells are in the Central Nervous System. They line the ventricles and spinal cord's central canal. They are the ones that help in the production and circulation of the cerebrospinal fluid (CSF). They are part of the blood-cerebrospinal fluid barrier, keeping the cerebrospinal fluid clean, and they also absorb the CSF.
The microglia are the macrophages of the Central Nervous System. They phagocytize any pathogen that they detect in the CNS, protecting the neurons.
The myelin sheath is formed by the oligodendrocytes in the CNS and by the Schwann cells in the PNS. Their function is to insulate the axons so that the electrical impulse can travel through them.

reactants = carbon dioxide & water
energy source = light
waste product = oxygen
primary energy = glucose
Explanation:
The energy source is light, reactants are carbon dioxide and water, the waste product is oxygen and primary energy is glucose.
What is photosynthesis?The sustainability of the significant number of life on Earth depends on photosynthesis. It is how almost all of the energy in the biosphere is made accessible to living beings.
All higher living forms on Earth consume photosynthetic organisms directly or indirectly since they are the primary producers that serve as the foundation of the planet's food webs.
Additionally, photosynthesis is responsible for producing virtually all of the oxygen in the atmosphere. The majority of creatures would vanish, there might soon be little food or other organic stuff on Earth, and the atmosphere would eventually be almost barren of gaseous oxygen if photosynthesis stopped.
Commonly used notation for photosynthesis is: 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂. This indicates that the reactants, six carbon dioxide molecules, and six water molecules, are transformed into a sugar molecule and six oxygen molecules, the products, by light energy being absorbed by chlorophyll (implied by the arrow).
The creature consumes the sugar, and as a byproduct, oxygen is produced.
Therefore, the energy source is light, reactants are carbon dioxide and water, the waste product is oxygen and the primary energy is glucose.

Pls mark brainliest!Marianne is conducting an experiment on homeostasis in paramecium, which is a type of single-felled organism. Which of these observations provides the strongest evidence of a paramecium maintaining homeostasis
Answers
Hello. You did not present the answer options, which makes it difficult for you to receive a specific answer. However, I will try to help you in the best possible way.
One of the most common evidences that a paramecium is maintaining homeostasis is the pumping of water from the vacuoles present in its body.
The paramecium is a protozoan that lives in aquatic environments, mainly those composed of fresh water. The problem with this environment is that water is able to enter the paramecium organism in large quantities and this can promote the disruption of the organism through lysis of the cell. In this case, homeostasis must act quickly and pump water out of the body, through the cell vacuole.
Homeostasis is a regulatory system of the organism, which must promote the balance of the organism, whenever any external or internal factor tries to harm this balance.

Choose one of the following scenarios and answer the questions provided. Support your answers using scientific reasoning and discussing possible impacts to individuals, society, and the environment. Be sure to also discuss any medical or ethical issues that may apply. (10 points)
Scenario 1:
Genetic engineering can be used to create more productive strains of farm animals. By adding genes to an animal's DNA, the animal can be made to produce milk or meat containing vital nutrients that would not be found naturally in those products. This provides a greater amount of nutrients per serving of milk or meat.
Do you think that this type of genetic engineering should be pursued? Explain your answer. (5 points)
What are some possible impacts (positive and negative) of this type of genetic engineering on individuals, society, and the environment? (5 points)
Scenario 2:
In the future, doctors may be able to evaluate your DNA to check for genetic markers related to specific medical conditions or harmful reactions to medications. Your personalized genetic profile could be kept on record and referred to in order to develop personal medical treatment based on your unique DNA sequencing. Scientists have found that just small variations in a specific section of your DNA can help determine how well some medications can work for you or if they would be beneficial at all.

Answers
Question 1:
I would want to have my DNA profile kept in a medical record for doctors to see, because if anything ever happens to me, and they need a reading of my DNA they have it available.
Question 2:
There are definitely pros and cons for having tests done and referring to DNA sequences when trying to refer to a patient's medical treatment. A pro would be that doing this it gives a lot of information about your DNA, and it provides helpful information so if doctors ever needed to perform treatment, that would be a good source for them to go too. A con would be if you ever have a treatment done, and scientists refer to your DNA sequence and proscribe medicine, they won't know how you will react to the medicine, and if it will work.
Question 3:
Having this technology now will definitely help us pin-point any genetic diseases in individuals, because of the copies of their DNA.
Answer:
i tried my best (so many questions on scenario 2)
Explanation:
scenario 1: there are many positive and negative possible impacts that come with genetic engineering. A very negative outcome could come from just one mistake. But if there was a way to ensure that nothing could go wrong than the outcome would be an healthy new meat or milk that's packed with nutrients.
scenario 2: I think if this was a real thing i would be completely for it. If a person was to get their DNA checked then doctors would be able to prescribe a medication that would fit you. this could also prevent any allergic reactions to and medications or treatments.
I personally would want my DNA profile kept on record so that i can be treated with the right medications for me.

Answers
Answer:
Fibrinogen is present in much higher amounts than what is required for coagulation while Prothrombin is present in low amounts in order to prevent excess conversion to thrombin during blood clotting
Explanation:
Fibrinogen is functional for processes such as inflammation, atherogenesis and not for blood Coagulation and they are required to form Fibrin fibers which will in turn form blood clots. Fibrinogen is present in much higher amounts than what is required for coagulation while
Prothrombin is present in low amounts in order to prevent excess conversion to thrombin during blood clotting. and this is because increased concentrations of thrombin will lead to an extensive intravascular thrombosis

Which type of stem supports giant trees?
A. herbaceous
B. gummy
C. woody

Answers
The type of stem that supports giant trees is woody, which is option C. Woody stems are the type of stems that support giant trees, so the correct option is option c.
Woody stems are characterized by their hardness and rigidity, which are due to the presence of wood tissue. This wood tissue provides structural support and allows the stem to grow thicker and stronger over time. Giant trees, such as oak, maple, pine, and redwood trees, have woody stems that enable them to reach great heights and support their extensive branching systems. Herbaceous stems, on the other hand, are softer and more flexible. So the correct option is option C.
