what is the meaning of
•molecule
•compound
•atom
•element
•organic compound
•inorganic compound
Molecule: a molecule is the smallest particle in a chemical element or compound that has the chemical properties of that element or compound. Molecules are made up of two or more atoms that are held together by chemical bonds. These bonds form as a result of the sharing or exchange of electrons among said atoms. Although oxygen is an element, it naturally has 2 atoms (O2), because it is a halogen and in order to reach 8 valence electrons and become stable and unreactive, it bonds with another oxygen atom. This means that oxygen atoms and oxygen molecules are different; one is an element, the other is a molecule.
Pure Substance: can be divided into two sub-categories: compounds and elements.
Compound: A chemical compound is a chemical substance composed of many identical molecules composed of atoms from more than one element held together by chemical bonds. A molecule consisting of atoms of only one element is therefore not a compound, meaning that oxygen molecules (O2) are NOT compounds. NaCl, or table salt, is.
Atom: An atom is the smallest unit of ordinary matter that forms a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms.
Element: An element is a pure substance consisting only of atoms that all have the same numbers of protons in their atomic nuclei. Elements are the base, more "pure" of the pure substances. Each element is assigned a symbol. Perhaps the most recognizable of them is H, for hydrogen.
Organic Compounds: organic compounds are generally any chemical compounds that contain carbon-hydrogen bonds. The study of these is called organic chemistry. I mean, carbon is the basis of ALL known life.
Inorganic Compounds: They are any substance in which two or more chemical elements (usually other than carbon) are combined, nearly always in definite proportions. Compounds of carbon are classified as organic when carbon is bound to hydrogen. THE OPPOSITE OF ORGANIC COMPOUNDS.

PLEASE HELP! WILL GIVE BRAINLIEST. Describe the contribution of photosynthesis and cellular respiration to the exchange of carbon between the atmosphere and the biosphere.
Cellular respiration and photosynthesis are essential to the carbon cycle because cellular respiration involves the intake of oxygen o2 and the exhale of carbon-dioxide co2 into the atmosphere. Where photosynthesis uses the carbon dioxide and water to create oxygen and sugars through energy to repeat the cycle. Respiration in general is a process where carbohydrates are turned into dihydrogen monoxide or water and co2(carbon dioxide). Living organisms together throughout the biosphere and atmosphere work together to continue this because carbon itself is an organic substance.
Answer:
Explanation: Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.

should be a minimum of 3 sentences).
Answer:
Adopting sustainable and environment friendly practices
Explanation:
Sustainable and environment friendly practices allows an individual to use available resources without depleting them and hence even the future generations have adequate supply of natural resources. Afforestation and conservation of water resources specially the potable water sources need to be started immediately with massive force.

What are 2 other differences between plant and animal cells besides cell walls?
Answer:
. The main structural differences between plant and animal cells are the additional structures found in plant cells. These structures include: chloroplasts, the cell wall, and vacuoles. In animal cells, the mitochondria produces the majority of the cells energy from food.
Como se chama a transferencia de enrgia termica flui de um corpo com maior temperatura quando ao outro de menor temperatura quando ha diferença de temperatura entre ambos
Answer:
Conduction.
Explanation:
Conduction is the process in which heat energy is transferred from the hotter body towards colder body because of temperature difference between two bodies. Conduction occurs only due to physical contact between two bodies. In the conduction process, the thermal energy flows from a body with a higher temperature to the other body having lower temperature until both bodies having same temperature.

In 100 words or more, construct and argument supported by empirical evidence to compare and contrast the
characteristics of viruses and organisms.
Help me
Answer:
Organisms and viruses both do not contain a DNA enclosing nucleus; however, these organisms differ greatly in the complexity of their structures. Generally an organism is encompassed within a semi-rigid cell wall made of peptidoglycan, which provides structural support. It is classified as gram positive if its cell wall is thick and stains purple when tested for identification. If its cell wall is thin and stains red, it is referred to as gram negative. Under the cell wall, the organisms also has a plasma membrane made up of a phospholipid bilayer with proteins inserted inside. Within its cytoplasm, ribosomes for protein synthesis and a single

what is the botanical name of milk
Answer:
Milk of magnesium's scientific name is magnesium hydroxide, and the scientific name for milk of sulfur is precipitated sulfur.
The botanical name of milk is not applicable, as it is not a plant or a plant product. Botanical name is the scientific name given to plants, fungus and algae.
Milk is a nutrient-rich fluid produced by mammals. It is frequently consumed as a source of nutrients and is renowned for having a lot of calcium. Water, lipids, proteins, carbs, vitamins, and minerals are all present in milk in complicated proportions.
There is no particular botanical name for milk in the field of biology, which is the study of plants and their categorization. Different plant species are identified and categorized using botanical names.
Milk lacks a botanical name since it is a byproduct of animals, not plants.

What is the difference between a GMO and cloning
Please help if you know the answer please
Answer:
A GMO Genetically Modified Product though similar to cloning is quite different. Cloning is the process of using egg cells from an individual to produce a new organism. When the baby is born, it is genetically identical to the parent, an exact copy. This process occurs in a lab. Genetic Engineering, which is used to make GMOs, uses technology to alter or change an organism's genes. New genetic information can be added to or removed from an existing set of DNA.
So I would say that some of the differences between GMOs and cloning include that:
Cloning strives to create exact copies of an organism's parent while GMOs remove and add different genes to form desired offsprings like making a product last longer or making the product grow larger faster.
Hopefully, this helped you! Have a nice day :)
