<h3><u>Answer;</u></h3>
Phloem
<h3><u>Explanation;</u></h3>
- <u>Club moss</u> plant belongs to the the family Lycopodiaceae, Lycophyte includes any spore-bearing vascular plant.
- <u>Liverworts</u> on the other hand are bryophytes which belongs to the division bryophyta. Bryophytes are small, non-vascular plants which includes mosses, hornworts and liverworts.
- <em><u>Vascular plants contain vascular tissues which play an important role of transportation in plants. </u></em>The major vascular tissues are phloem and xylem. <em><u>Non-vascular plants</u></em> on the other hand lacks the vascular tissues for transportation of substances.
Two molecules that can cross a lipid bilayer without help from membrane proteins are oxygen and carbon dioxide. The property that allows this to happen is that both oxygen and carbon dioxide molecules are nonpolar which means that they can pass easily through the hydrophobic part of the membrane. The lipid bilayer is present in all cell membranes. It consists of two layers of the fat cells which are arranged into two sheets. It functions as a barrier which marks the boundaries of the cell. The inner part of a lipid bilayer is nonpolar since it is composed of the hydrophobic end of the phospholopids.
Your best guess for the boiling point of any version of Coke would be 100 C, the boiling point of water.
Diet Coke is mostly water (the flavourings are a very small amount relative to the amount of water). The largest ingredient will be the sweetener but there will be only a fraction of a gram of that. It is unlikely you will notice any deviation from the properties of water.
Standard Coke has quite a lot of sugar in it. A standard can (~300ml) contains about 40g of sugar. To put it another way, the contents are more than 10% sugar by weight and the solution is about 1/3 mol/L of sucrose (other sugars will be slightly different). A standard calculation using the ebullioscopic constant for water suggests the elevation of the boiling point will be barely 0.2 C, so small you'd struggle to measure it without good instruments and a good experimental setup.
Answer:
Atoms bind because, being united, they acquire a more stable situation than when they were separated and this allows them to exist in nature. This situation of greater stability usually occurs when the number of electrons that possess the atoms in their last level is equal to eight, structure that coincides with that of the noble gases.
Quemical bonding refers to the attraction forces that keep bonded the atoms in compounds, and there are two main types of chemical bonding: ionic and covalent bonding.
Explanation:
1)<u> Ionic bond:</u> results of the electrostatic interaction between ions, that results in the net transfer of one or more electrons from one atoms or group of atoms to other atom.
<em><u>Example of ionic bond:</u></em>
Sodium Chloride Na-Cl +, Sodium ion has a positive charge and chlorine ion has a negative charge, so chlorine seats an electron to sodium creating a ionic bond.
2)<u> Covalent bond:</u> In this type of chemical bond two atoms shares one or more pairs of electrons.
<em><u>Example of covalent bond</u></em>
Carbon monoxide is an example of a compound that has covalent bond, one carbon atom and one oxygen atom, linked by a triple bond that consists of two covalent bonds as well as one dative covalent bond.
