Answer:
The carbon, phosphorous, water and nitrogen cycles are considered to be biogeochemical cycles because all of the cycles are cycles in which chemical and simple substances are transferred between living systems and the environment. Simply put, they all include the biosphere, chemical Please Mark Brainliest If This Helped!
Mitosis occurs in the nucleus and forms 2 identical cells; it is a continuous process, but can be subdivided into 4 phases: prophase, metaphase, anaphase, and telophase; the resulting cells are exact duplicates (clones) of the parent cell. All DNA is double stranded but if it’s meant a single molecule of DNA, it happens in metaphase. Each chromosome makes a copy of itself during DNA synthesis wherein the original chromosome and its copy are joined together. This complete structure is called a chromosome. The two parts (original chromosome and its copy) are called chromatids. At metaphase the two chromatids begin to separate. Each chromatid, once separated, is renamed a chromosome and consists of single DNA molecule.
Answer:
a flow
Explanation:
Movement of soil and regolith that more resembles fluid behaviour is called a flow. These include avalanches, mudflows, debris flows, earth flow, lahars and sturzstroms. Water, air and ice are often involved in enabling fluid-like motion of the material.
Depending on what resources you use, it can be easy or difficult to get examples of each categories
Some easy way can include searching google, wikipedia, encyclopedia.org, etc. These usually give you a broad and large amount of information that you can draw out of, and an over view that allows you to know what the paragraph would be talking about before you use it.
Difficult ways would be searching through specific websites, such as national geographics, etc, which gives you specific details on the idea (and is more trusted then the others)
Remember too always get facts, not opinions, unless your question asks for others opinions, and to look for what researchers or well-known people within that topic says, and to not get any information from "who-knows-who-typed-it" websites, such as ask.com, etc.

Answer:
In order for a polar compound to enter into the hydrophobic space of the phospholipid tails, it would need to break the many <u>polar covalent bonds</u> bonds it has formed with the water and enter into a space where these bonds cannot form. Therefore, it is not a repelling action but a "lack of attraction".
Explanation:
<u>Water as polar solvent and the phospholipids:</u>
Water is very different on the molecular and that is due to the more polar nature, which is caused by the hydrogen bonding with in a H₂0 molecule. As the water molecules forms bonds with the other molecules in a specific formation of unequal polarities on its molecules. As the molecules have an unequal amount of charges present on it. For, the phospholipids they have two hydrophobic tails and the hydrophilic head. Through which they form most of the cell membrane structures.
In order to add any polar molecule to the hydrophilic head of the phospholipid there are many covalent bonds which are required to be broken, as these bonds include the covalent bonds found inside the molecular level. While, the hydrophobic tails of the molecules can't arrange themselves to form the bonds with the polar molecules more frequently.
