What tells a muscle when to contract?
Answer:
What tells a muscle when to contract?
Explanation:
(1) A message travels from the nervous system to the muscular system, triggering chemical reactions.
(2) The chemical reactions lead to the muscle fibers reorganizing themselves in a way that shortens the muscle--that’s the contraction.
(3) When the nervous system signal is no longer present, the chemical process reverses, and the muscle fibers rearrange again and the muscle relaxes.
Answer:
The nervous system generates a signal, which triggers a muscle to contract

Ionic compounds form because charges attract
The formation of ionic compounds is due to when opposite charges attract and like charges repel, the attraction of opposite charges makes ionic bonds in the compounds.
What are ionic bonds?It is the kind of bonding in which electrostatic attraction happens, through which ionic compounds are formed.
Ionic bonds set the chemical connection in which one atom loses valence electrons and which are gained by another atom, the atoms involved in this connection form the more stable noble gas electrical state.
This bonding is different from covalent bonding, in covalent bonding there is sharing of the pairs of electrons making it more strong than ionic.
Therefore, ionic compounds form because opposite charges attract each other, leading to ionic bonding.

The coordinated action of two types of myofilaments, actin and myosin, results in muscle contraction. The muscles contract as actin filaments slide over myosin filaments. When the muscle is in a relaxed state, the myosin heads are ready to bind with the actin filament. However, they are not able to bind due to
a.
the absence of ATP
b.
a high concentration of Ca++ ions
c.
blockage of the attachment site
d.
alcoholic fermentation
Answer:
I think due to absence of ATP but I'm not sure.. Actin and myosin return to their unbound state causing the muscle to relax. Alternatively relaxation (failure) will also occur when ATP is no longer available.
Myosin heads are ready to bind with the actin filament they are not able to bind due to the absence of ATP.
How two myofilaments involved in muscle contraction?Muscle contraction results from an intercommunication between the actin and myosin filaments which generate movement relative to one another.
What happens to the actin and myosin filaments when a muscle contracts?Myosin movement appear to be a kind of molecular hop. The myosin reaches forward, binds to actin, contracts, releases actin, and then reaches forward again to bind actin in a new cycle.
What happens to actin and myosin during muscle relaxation?Relaxation occurs when nerve stimulation stops. Calcium gets moved back into the sarcoplasmic reticulum shattering the link between actin and myosin. Actin and myosin then return to their unbound state causing the muscle to relax.

Atoms are made up of protons and neutrons located within the nucleus, with electrons in orbitals surrounding the nucleus.
Lithium:Lithium is a chemical element with the symbol Li and atomic number 3. It is a soft, silvery-white alkali metal. Under standard conditions, it is the lightest metal and the lightest solid element. because it is present in trace amounts in virtually all rocks.
Florine:Fluorine is a chemical element with the symbol F and atomic number 9. It is the lightest halogen and exists at standard conditions as a highly toxic, pale yellow diatomic gas. As the most electronegative element, it is extremely reactive, as it reacts with all other elements, except for argon, neon, and helium.
Electron:Electron is a free and open-source software framework developed and maintained by GitHub. It allows for the development of desktop GUI applications using web technologies: it combines the Chromium rendering engine and the Node.js runtime.
Neutron:The neutron is a subatomic particle, symbol n or n⁰ , which has a neutral charge, and a mass slightly greater than that of a proton. Protons and neutrons constitute the nuclei of atoms.
Proton:A proton is a subatomic particle, symbol p or p⁺ , with a positive electric charge of +1e elementary charge and a mass slightly less than that of a neutron. Protons and neutrons, each with masses of approximately one atomic mass unit, are jointly referred to as "nucleons".

Four students are discussing heat, thermal energy, and temperature. Claire says temperature indicates the amount of heat in an object. Hazel states that heat is a transfer of energy. Connor says that, if two objects have equal masses, the hottest object has the most thermal energy. Evan disagrees. He says that, if two objects have equal masses, the hottest object has the most heat.
Answer:
Claire and Conner are correct
Explanation:
trust me.....
Among the four students, Hazel and Connor are correct in their statements. Heat is indeed a transfer of energy, as stated by Hazel. Similarly, Connor is right in saying that if two objects with equal masses are compared, the hottest object possesses the most thermal energy. Thus, correct option is (d).
Hazel is right when she says that heat is the thermal energy that is transferred between objects when there is a temperature difference. This is a cornerstone idea in thermodynamics. The claim made by Claire is untrue because temperature really measures the average kinetic energy of an object's molecules rather than the quantity of heat it contains.
The idea that thermal energy, which is connected to the kinetic energy of particles in an object, rises with temperature is supported by Connor's assertion. Consequently, the object with a greater temperature does actually have more thermal energy when two things have equal masses.
Evan's argument against Connor's assertion is unfounded. Temperature measures the intensity of heat, not the overall amount of thermal energy. Therefore, the correct pair of students are Hazel and Connor (option d).

The inflammatory response is a type of body response produced in response to damaged tissue, attack of pathogen and or any other cause.
The body shows an inflammatory response in the following manner:
1. Recognition of stimulus- receptors recognize the antigens.
2. Release of inflammatory markers: affected cells produce chemicals like histamine, bradykinin, and prostaglandins.
3. Vascular permeability changes and leukocyte (WBC) recruitment- released chemicals causes the blood vessels to leak fluid causing swelling and attract WBC.
4. Accumulation of leukocytes- WBC performs the process of phagocytosis which eats dead or damaged cells and germs.

happens in this process?
The reaction uses water molecules to break the bonds in each glucose.
O4 water molecules are lost from each bond broken
O 4 Water molecules are used for every
O 1 water molecule is lost (OH + H) for every bond formed
Glucose molecules bond together in a process known as dehydration synthesis, and in this process, 1 water molecule is lost (OH + H) for every bond formed. The last option is correcting the glucose dehydration reaction.
What is glucose dehydration?The macromolecules, such as the polysaccharides and proteins, are formed by the dehydration reaction, and in this reaction, the water is lost to make the polymer. The single glucose molecules unite with each other and release a single unit of water to form the polymers, and in this way the polymers such as glycogen, starch, and cellulose are formed.
In the case of proteins, each amino acid dehydrates and releases one molecule of water, forming the polypeptide chain. As a result of the dehydration process, the monomers combine to form the polymer, which can be structural or functional.
Hence, for every bond formed, one water molecule (OH+H) is lost. The last option is correct regarding the glucose dehydration reaction.

1. List 2 interactions between the earth spheres and the water cycle.
2. List 2 interactions between the earth spheres and the carbon cycle.
3. List 2 interactions between the earth spheres and the nitrogen cycle.
Answer:
The carbon cycle, as the nitrogen cycle, occurs in all the spheres: Biosphere, Atmosphere, Geosphere and Hydrosphere.
Explanation:
Most Earth events involve interaction between multiple spheres. For example, rain is the movement of water (the hydrosphere) from the atmosphere to the lithosphere where it collects in lakes, rivers, or streams. Water is an important resource for inhabitants of the biosphere.
The Atmosphere-contains all the air in Earth's system. The upper portion of the atmosphere protects the organisms of the biosphere from the sun's ultraviolet radiation. It also absorbs and emits heat. This sphere is also where weather occurs.
The nitrogen cycle occurs in all the spheres and ecosystems. It passes through rocks, water, atmosphere, plants, etc.
In atmosphere and biosphere: Nitrogen is about 78% of the gases in the atmosphere an it’s a essential component of the living organisms. It enters plants through the microorganisms that convert this nitrogen into ammonia. After this conversion, the plants absorb this substance. It can pass to animals when they eat these plants. Then, when they urinate, bacteria convert ammonia to nitrogen again and it returns to the atmosphere.

What is Regeneration?Regeneration may be defined as a process through which the reactivation of development into post-embryonic life in order to restore missing or damaged tissues is carried out.
The process of regeneration is carried out in Hydra (Morphollactic regeneration), Planaria (Stem cell-mediated regeneration), Salamander (epimorphic regeneration), and Mammalian liver (compensatory regeneration).
In reptiles like Salamander, epimorphic regeneration is carried out through which differentiated cell undergoes cell dedifferentiation in order to form regeneration blastema. This region is stimulated by the apical ectodermal cap (AEC).
Therefore, the reptiles regrow the body parts which are lost due to injury by the action of regeneration.
