Name three reasons why the atmosphere is important to life on earth and explain your reasoning.
The atmosphere ensures that all living things can carry out daily processes that are vital to survival, such as breathing. Photosynthesis, for example, could not be possible without an atmosphere, because all of the gasses in our atmosphere stay there due to Earth's gravity.
The atmosphere is vital because it plays a role in the water cycle as well, allowing rain to keep falling and giving life-giving water to organisms that need it.
Life would not be possible without an atmosphere on this planet, along with other vital things, like gravity, sunlight, and water.

Camouflage is the use of any combination of materials, coloration, or illumination for concealment, either by making animals or objects hard to see, or by disguising them as something else. Examples include the leopard's spotted coat, the battledress of a modern soldier, and the leaf-mimic katydid's wings.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.

For the compound C₆H₁₂O₆, what type of bond would join the elements and why?
1. covalent because an electron is transferred from a C atom and O atom to a H atom.
2. covalent because electrons are shared between the C, H, and O atoms
3. ionic because an electron is transferred from a C atom and O atom to a H atom.
4. ionic because electrons are shared between the C, H, and O atoms
Answer:
4. Ionic bond because electrons are shared between the C,H and O atoms.
Explanation:
The atomic no. of carbon=6
Electronic configuration=2,4
The atomic no of H=1
E.C=1
The atomic no of O=8
E.C= 2,6
Therefore to attain octate state, they will share electrons

At the bottom of the food chain, the herbage, are the producers. All the other organisms above the producer are consumers. In economics, the food chain is the series of processes by which we grow, sell, and eventually consume food. This article focuses on the term when it refers to organisms that depend on each other as a source of food.

Organisms of either extreme characteristic dying out while organisms with the medium characteristic have a higher fitness is identified as?
Answer: Stabilization selection
Explanation:
Natural selection involves the differential survival and growth of organisms which have suitable traits to survive in unfavorable or adverse environment. Such traits are passed on to the next generation. Stabilization selection is a type of natural selection in which the nature selects the non-extreme phenotypic traits. Middle traits are selected and such organisms grow and reproduce. Example can be given that of human babies in which babies with low weight lose more heat and babies with high weight are difficult to be delivered from the pelvis. Therefore, babies with middle weight are expected to survive more than that of low or middle weight.

Which gas is used by humans in the process of cellular respiration?
Answer: Oxygen
Explanation:
During the process of cellular respiration, carbon dioxide is given off as a waste product. This carbon dioxide can be used by photosynthesizing cells to form new carbohydrates. Also in the process of cellular respiration, oxygen gas is required to serve as an acceptor of electrons.

The cell cycle is the life of the cell from the time it is first formed from a dividing parent cell until its own division into two cells
Explanation:
cell cycle is made up of three main parts: interphase, mitosis, and cytokinesis. Most biologists agree that interphase makes up the period of time that a cell would be preparing for cell division. Cells spend the majority of their lives in this stage. During interphase a cell is going to be growing, replicating its genetic material and essentials to carry out cell division, and proofreading the genetic material to ensure replication has occurred correctly. This doesn’t sound like much, but it’s actually the longest part of the cell cycle. Once this is complete, the cell will then go through cell division and, theoretically, split into two new cells (cytokinesis).
How cytokinesis works will depend upon the type of cell that is dividing. Here is an image that summarizes the differences in cytokinesis in plant cells and animal cells, which is the classic example used in many introductory biology courses:

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.
