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.

Bones and Muscles

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

Answer:

the axolotl ( say "ax- oh- lot-el") is a Mexican species of salamendar . its also known as mexican walking fish .it can regenerate , repair or replace its arms,legs,tail ,lower jaw ,brain and heart

Explanation:

in reptile involves dropping a section of their tail and regenerating it as part of a defense mechanism

The reptiles regrow the body parts which are lost due to injury by the action of 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.

Answer: Your diet can probably effect. More animals may consume more water than others. Or more plants drink more water than others. by eliminating these animals, there is more water left. Some plants that use the last water is the Sago Palm, Snake plant, Orchids, Spider plant, and plenty of the plant species who are adapted to dry climats. The plants that consume the most water are Ferns, Lilys, Daylilies, Indian grass, Cattails, Iris, and Elephant ears. The animals that consume the most water is probably the biggest animals like elephants and cows, who according to my search can consume up to 100 gallons of water a day durring hot summer months. So, the least water, the less it will rain, the less clouds there would be, and the easier it would be for the land to dry out.

Explanation:

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.

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.

Passive transport is the movement of substances across the membrane without the expenditure of cellular energy.

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.

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.

Muscle contraction results from an intercommunication between the actin and myosin filaments which generate movement relative to one another.

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.

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.

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).

Explanation:

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.

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.
