Using the scenario shown in the comic strip, write a script that describes what the nervous system might say to other body parts to make the boy blink his eyes and then swat the bug.
In the diagram, sensory receptors work together to send a message to the CNS (presence of a mosquito). Subsequently, the SNS acts to drive a corresponding muscle (arm) movement.
Sensory receptors such as, in this case, touch sensory receptors and mechanoreceptors, transmit signals to the Central Nervous system (CNS).
The CNS includes the brain and spinal cord and is responsible for receiving information from the peripheral nervous system (PNS).
The PNS can be divided into the somatic nervous system (SNS) and autonomic nervous system (ANS).
Subsequently, the CNS sends signals to the skeletal muscles of the somatic nervous system (SNS) that control voluntary movements and also reflex arcs.

Which major event (or events) likely allowed eukaryotes to evolve? (select all that apply)'
The oxygenation of atmosphere is major event (or events) likely allowed eukaryotes to evolve. The current atmosphere is oxidizing because it has a lot of oxygen in it. The increase in oxygen is credited to cyanobacteria, which are considered to have first emerged some 3.5 billion years ago and are responsible for photosynthesis.
Blue-green algae, often known as cyanobacteria, are the cause. These microbes make carbohydrates and, yes, oxygen through photosynthesis, which involves using sunlight, water, and carbon dioxide. Thus, the oxygenation released by cyanobacteria led to modifications in the composition of the earth's atmosphere, the emergence of aerobic metabolism.

Tendon sheaths ________. Tendon sheaths ________. are lined with dense irregular connective tissue help anchor the tendon to the muscle are extensions of periosteum act as friction-reducing structures
Answer:
Tendon sheaths act as friction-reducing structures.
Explanation:
Tendon sheaths are fibrous tissue that is around tendons to protect and make the movements of these smoother. For example, they reduce the friction of the flexors and extensors tendons of the hand. These are tendons that we constantly use to open and close our hands when we want to grab objects. Without the sheath, the tendons will not move easily, and due to the excessive use, there can be inflammation.
The sheats have two layers, one internal, which is a synovial one that produces synovial fluid to lubricate the tendon, and the external, which is a fibrous layer.

Decreased H+ will have what effect on ventilation and which acid-base balance disorder would it be compensating for?
When acid-base disorder balances or imbalances then, they would be compensated for by decreased H+ in terms of ventilation and respiratory acidosis.
The main causes of respiratory acidosis are inadequate ventilation and carbon dioxide buildup. A clinical condition known as acidosis is characterized by an abnormal increase in hydrogen ions (H+) in the extracellular fluid. Reduced ventilation results in less carbon dioxide (CO2) leaving the body, which raises PCO2 levels and reduces pH.
Hypoventilation is the main issue that leads to respiratory acidosis. The respiratory reaction to metabolic alkalosis also includes hypoventilation. By hyperventilating, the respiratory system can also reduce CO 2. This results in a reduction in [H+] and an alkalosis.

A plant wilts and becomes floppy if it loses water faster than the roots can absorb water. Explain why a plant is more likely to wilt when the weather is hot and windy, rather than cool and still. :)
Answer:
Explanation: When the weather is hot and windy plants generally wilt because of the higher rate of transpiration.
Transpiration refers to the mechanism by which water evaporates from a plant's leaves.
The air surrounding the plant generally becomes hot and windy resulting in a faster rate of water loss through the leaves whereas the root struggles to absorb enough water from the soil to balance the water loss through leaves.
As a result, the plant suffers from water deficiency which causes withering and floppiness.
In contrast the rate of transpiration is reduced in cool and quiet weather, lowering the likelihood of water loss exceeding the roots ability to absorb water.

part of the cytoskeleton involved in cellular movement
Cell mobility is supported by hemocytes. For instance, microtubules sliding against one another causes cilia and (eukaryotic) flagella to move.
Hemocytes from Drosophila melanogaster are an excellent resource for analyzing important facets of immune cell movement. The cytoskeleton not only performs this structural function, but it also controls how cells move. Microtubules are expected to create a polarised network that enables the transport of organelles and proteins throughout the cell, while the actin cytoskeleton is assumed to supply protrusive and contractile forces. The cytoskeleton's core duties include controlling how cells are shaped, supplying mechanical support and integrity, allowing for cell mobility, and facilitating the intracellular movement of supramolecular structures, vesicles, and even organelles.

Which of the following was observed in studies measuring the efflux of radioactive sodium from the squid giant axon?
a. Dramatic increase of efflux during a brief train of action potentials
b. Sharp drop in efflux when intracellular potassium was removed
c. Dependence of efflux upon the presence of ATP
d. Decrease of efflux when ATP synthesis was increased
e. No recovery when potassium or ATP was restored.
Dependence of efflux upon the presence of ATP was observed in studies measuring the efflux of radioactive sodium from the squid giant axon.
So, the correct option is C.
The squid giant axon is a highly specialized biological device whose primary function is to consistently and quickly activate the squid's mantle muscles to produce its jet propulsion mechanism. In order to circumvent this issue, Hodgkin and Huxley looked at the action potentials in the squid's comparatively massive axons, which may reach 1 mm in diameter. When an action potential occurred, they were able to quantify electrical alterations in the squid giant axon by inserting a tiny capillary electrode into the axon measured efflux of radioactive sodium.
One of the most significant discoveries regarding the brain came from research on squid axons: the process underlying the "action potential," the electrical language used by brain cells to communicate.

The scales shown in the introduction measure mass or the amount of matter in a particular object. The scientific law of conversation of mass states that matter can both be created or destroyed during a chemical reaction but it can change from one form to another. Did the simulation support this scientific law? Explain why or why not.
The simulation of a chemical reaction does support the scientific law of conversation of mass that states that matter can neither be created nor destroyed but it can change from one form to another.
The scientific law of conservation of mass states that matter can neither be created nor destroyed but it can change from one form to another. This means that the mass of the reactants and the products must be the same, i.e., mass cannot be lost or gained.
For example, when the wood is burned, the products formed are ash, water vapour, and carbon dioxide. The mass of the ash, water vapour, and carbon dioxide formed during the combustion of wood is the same as the mass of the wood that was burned.
The simulation of a chemical reaction supports this scientific law as it has been observed that the mass of the reactants in a chemical reaction is equal to the mass of the products formed during the chemical reaction. Even if the products appear to have a different mass than the reactants, it is only because the mass has changed from one form to another, and not because the mass has been destroyed or created.
For instance, in the process of rusting, iron and oxygen react to form rust, which is hydrated iron(III) oxide. The mass of the iron and oxygen involved in the chemical reaction is equal to the mass of the rust formed. In conclusion, the scientific law of the conversation of mass states that matter can neither be created nor destroyed but it can change from one form to another, which is supported by the simulation of a chemical reaction.
