Answer:
A- Sensory Neuron
B- Spinal cord
C- Effector neuron
D - Brain
Explanation:
Sensory neuron: Its main function is to allow the reception of stimuli that are transformed into nervous impulses and electrical signals, capable of realizing sensations, such as a peliscão, for example. These impulses are transmitted to the spinal cord. Spinal cord: The main function is to support the body in an upright and vertical position. It also has the function of transmitting electrical signals and nerve impulses between some parts of the body and the brain. Effector neuron: Its main function is to receive muscle stimuli capable of creating muscle contractions. These neurons are located in the spinal cord. Brain: the processing center receives all the stimuli sent by the bone marrow. Its main function, in this case, is to produce bodily responses to the stimuli it has received, producing muscle movement.
Answer:
A: skin detects sharp nerve
B: spinal cord receives signal from sensory
C: the nerve impulse the muscle to contract

What was an unintended negative environmental consequence of improved technology in agriculture?
A. Farmers went bankrupt purchasing expensive equipment.
B. Modern technology allowed for larger expanses of land to become cultivated, so farming took over many natural areas that were important for wildlife
C. Machines took away jobs commonly performed by farm workers
D. Machines diminished the quality of the crops.
Answers
The correct answer is B. Modern technology allowed for larger expanses of land to become cultivated, so farming took over many natural areas that were important for wildlife.
Explanation:
In the last decades, the creation of agricultural technology has increased the efficiency of growing crops. This means now, all the process is more efficient, which leads to more products to be sold and an increase in profit. However, the possibility of large scale agriculture has caused more land is used for this purpose. This often implies natural ecosystems such as forests are destroyed and the land of these ecosystems, which is usually rich in minerals, is used for extensive agriculture. This is a negative consequence of agricultural technology as natural areas important for wildlife are taken for human profit.

4. If plant roots are exposed to air and sunlight for a few minutes, and then the plant is placed back in the soil, it will wilt before starting to recover. What is happening at the cellular/tissue level in the roots?
Answers
Answer:
Explanation:
If plant roots are exposed to air, particularly non woody plants that rely on water pressure to stay erect, they start to wilt because of the disruption between the balance of transpiration (loss of water through the stomata) and absorption of water by the roots.
Since the plant's root has been exposed, they are no longer able to absorb water, and then transpiration also occurs which leads to a faster loss of water causing the plants cells to become dehydrated and collapse leading to wilting of the plants.
But if water is provided immediately, they can recover
3. List the molarities at which water exited the potato strips. Why did water move out of the potato strips? Were these solutions hypotonic, hypertonic, or isotonic?
Answers
Answer:
The water came out of the strips of the potatoes because a process of balance and oxygen balance called osmosis occurs.
Explanation:
The potato was subjected to a hypertonic environment and it is considered hypotonic, that is why the water seeks to go out to the outside in order to generate that it finds a balance in relation to a solvent solvent.
Briefly explain what was done in the experiment where pigeons could choose which button to peck in the Skinner box. How does this relate to self-control?
Answers
In this experiment, Skinner placed a pigeon inside a box that contained a button that when pressed released water or food. This pigeon went through periods of deprivation of water and food, but over time, he realized that when he pecked the button he had access to these two elements. Skinner called this behavior operant behavior, which is the behavior that occurs controlled by its consequences.
Although Skinner did not specifically study self-control, with this experiment, we can make a connection between operant behavior and self-control, since both are behaviors shown as a way to change the environment in which they are inserted, but this change also affects them.
The possibility of magnifying contaminating sequences present in a nucleic acid pool is a drawback associated with PCRs high level of sensitivity (i.e., potential for exponential amplification).
A. True
B. False
Answers
Answer:
True
Explanation:
The Polymerase Chain reaction (PCR) is a technique widely used in molecular biology to identify specific DNA fragments generally in a size range of 100 to 1000 base pairs (bp). PCR sensitivity refers to the potential of the PCR technique to specifically amplify the desired sequence in the sample. PCR is a highly sensitive (and also specific) method with values around 100% if the experimental conditions are proper. However, to reach these values, it is imperative to work in optimal conditions by eliminating contaminant factors in the sample which may alter PCR amplification.

Explain how conservation has saved the Bald Eagle (Site 1)
Answers
Answer:
Conservation allows the existence of trees essential for the reproduction of bald eagles.
Explanation:
As you may already know, environmental conservation is a term that represents the set of actions and activities that encourage the conscious and sustainable use of natural resources, allowing all environmental factors to be renewed and available in nature for many years.
One of the best consequences of conservation is the reduction of deforestation, which is very beneficial for the Bald Eagle to maintain its species. That's because this species of eagle keeps its eggs in nests raised in large trees. Without these trees, the bald eagle will not reproduce what will end up exterminating its species over time.

Why was there not a significant difference in the reaction rate with 800 mg of substrate as compared to 400 m. of substrate? What would you need to add to see an increase in the reaction rate with 800 mg of substrate?
Answers
Answer:
A. Concentration of substrate can affect the rate of reaction by two condition given below-
1. At low concentration of substrate, there will be increase in the rate of reaction by increasing the concentration of substrate. There would be catalytic site of enzyme available to bind to substrate.
2. The enzyme becomes saturated with substrate as the substrate concentration increases. At a point when the rate of product formation now depends on the activity or the available active sites of the enzyme itself, so, increasing more substrate will not leads to any effect on the rate of the reaction to any significant level.
Thus, there was not a significant difference in the reaction rate with 800 mg of substrate as compared to 400 m as at 400 mg all the catalytic site or active site are bound already.
B. Increasing the enzyme concentration will lead to increase the rate of reaction at 800 mg as there will be more active sites to bound to substrate.

option 1, 2, 4, and 5 are true while 3 is false.
Explanation:
statements are given below.
1) Anaerobic respiration occurs by either lactic acid or alcohol fermentation.
2) Glycolysis is the first step in anaerobic respiration only.
3) only anaerobic respiration produces a net gain of ATP.
4) anaerobic respiration occurs in the cells cytoplasm.
5) aerobic respiration always include the citric acid cycle.
Anaerobic respiration occurs by either lactic acid or alcohol fermentation and produces very low amount of ATP due to the absence of oxygen. Glycolysis refers to the breakdown of glucose molecule in pyruvate and ATP molecules. It only occurs in anaerobic respiration because it does not requires oxygen. Both aerobic and anaerobic respiration produces energy in the form of ATP. Aerobic respiration occurs in the mitochondria of the cell while anaerobic respiration occurs in the cytoplasm. Citric acid cycle is main part of aerobic respiration.

3. The sensory neuron generates an impulse.
1. Interneurons relay the impulse to motor neurons in the spinal cord.
5. Motor neuron signal the leg muscles
2. She immediately moves her foot.
Explanation:
The reflex arc refers to an action mechanism that responds to different stimuli. It is an involuntary reaction involving different nervous vias. The reflex arc is composed of receptors, afferent nervous fibers, efferent nervous fibers, and effectors.
Receptors are located in nervous terminals and are widely distributed in the organism. Receptors are capable of receiving stimuli from different nature, and most of them are specialized in one kind of stimuli such as vision, audition, touch, among others. In the exposed example, these sensory receptors were located in the toe, and probably they were touch receptors.
When they receive the stimulus the sensory neuron transforms it into an excitatory nervous impulse that goes to the central nervous system along the afferent nerves. This stage is known as the afferent via, beginning with the environmental information received by sensory receptors, and ending in the arrival of the transcripted message to the central nervous system.
When the central nervous system receives the information, it processes it and sends an appropriate answer according to the stimulus. The message goes along the interneurons to the motor fibers, which are in charge of taking that answer to its destiny, the effectors. Effectors are usually muscles or glands, and they transform the received impulse into a motor answer that executes the reflex action. In the exposed example, the effector in the muscle. This stage is known as the efferent via, beginning in the central nervous system sending an answer impulse and ending in the effector (muscle) executing the answer.

Receptors in her toe receive stimuli.
The sensory neuron generates an impulse.

The general function of an enzyme in the body is to ________. The general function of an enzyme in the body is to ________. eliminate waste products from the blood act as a reactant in carbohydrate storage catalyze chemical reactions maintain homeostasis maintain a neutral pH
Answers
Answer:
catalyze chemical reactions
Explanation:
An enzyme is a proteinous substance that acts as biological catalysts and increases the rate of biochemical reactions in the body. Enzymes are specific in nature which is as a result of the structure/shape of its building block (amino acid).
Enzymes speedens the rate of a chemical reaction in living systems, which would normally not occur or occur at a much slower rate, without the presence of an enzyme. Enzymes acts on the reactants called Substrates by binding to them to form products but they are not used up in the reaction. Hence, enzymes are not reactants.
In the presence of saturating amounts of oxaloacetate, the activity of citrate synthase from pig heart tissue shows a sigmoid dependence on the concentration of acetyl‑CoA. When succinyl‑CoA is added, the curve shifts to the right and the sigmoid dependence is more pronounced.
Choose the statements that are reasonable explanations for the right-ward shift of the velocity curve caused by succinyl-CoA.
a. Succinyl-CoA competes with dissociation of CoA as a product of the reaction.
b. Succinyl-CoA binds covalently to the enzyme.
c. Succinyl-CoA binds at a regulatory site other than the active site.
d. Succinyl-CoA competes with acetyl-CoA for binding at the active site.
e. Succinyl-CoA competes with oxaloacetate for binding at the active site.
Answers
Answer:
c. Succinyl-CoA binds at a regulatory site other than the active site
Explanation:
The sigmoid saturation curve is a property of of allosteric enzymes which reflects the cooperaive interactions between the protein subunits in the enzymes.
Allosteric enzymes function through reversible, non-covalent binding of regulatory compounds called allosteric modulators.
Allosteric enzymes have different binding site for the substrate and for their allosteric modulator.
In the citric acid cycle, succinyl-CoA serves as as allosteric inhibitor of citrate synthase which catalyses the production of citrate from oxaloacetate and acetyl-CoA.
From the given options:
a. Succinyl-CoA competes with dissociation of CoA as a product of the reaction is wrong because it has its own binding site as an allosteric modulator.
b. Succinyl-CoA binds covalently to the enzyme is wrong because allosteric enzymes functions through non-covalent interactions.
c. Succinyl-CoA binds at a regulatory site other than the active site is true because citrate synthase is an allosteric enzyme
d. Succinyl-CoA competes with acetyl-CoA for binding at the active site is wrong because acetyl-CoA binds to the active site while succinyl-Coa binds to the regulatory site.
e. Succinyl-CoA competes with oxaloacetate for binding at the active site is wrong because oxaloacetate binds to the active site while succinyl-Coa binds to the regulatory site.

Hemoglobin is the blood protein responsible for the transport of oxygen. Carbon monoxide disturbs oxygen transport by
Answers
Answer:
Answered below
Explanation:
Hemoglobin is found in the red blood cells and is responsible for the transportation of oxygen from the lungs to the various body cells.
Oxygen binds to hemoglobin because it has a high affinity for it. This aids its transportation. When it gets to the cells it unbinds and get transported into the cell for use in energy production.
Carbon monoxide is an odourless, dangerous gas which has more affinity for hemoglobin than oxygen. Therefore when carbon monoxide is inhaled, it quickly binds to hemoglobin, thereby displacing oxygen. It binds to hemoglobin for a longer period and due to this, the body does not get any oxygen and cells begin to die.
Symptoms of carbon monoxide poisoning include dizziness, headaches, fatigue and coma.
