Answer:
Water is the common solvent of the body
Water is a polar, covalent molecule
The high heat capacity of water relates to its ability to absorb significant
amounts of heat before changing one degree celsius
.
Acids have a higher concentration of free H+ than are found in bases
Explanation:
Water is also called universal solvent because it can dissolve a large number of polar compounds due to its polar nature. In water, covalent bond is present between hydrogen and oxygen due to which partial positive charge occurs on hydrogen and partial negative charge appears on oxygen atom due to difference in electronegativity values. Acids has high concentration of proton (H+) while bases has high amount of OH- ions.
Answer:
Cell adhesion, ion conductivity, and cell signaling.
Explanation: Cell membranes are involved in a variety of cellular processes such as cell adhesion, ion conductivity and cell signalling and serve as the attachment surface for several extracellular structures, including the cell wall, the carbohydrate layer called the glycocalyx, and the intracellular network of protein fibers called the cytoskeleton. In the field of synthetic biology, cell membranes can be artificially reassembled.
Explanation:
Carbon has four electrons in its outer most orbit and it can share four more electrons from other atom to complete its valency while oxygen has 6 electrons in its outermost orbit and it can either charge the electron or gain two electrons from other atom.
Therefore in 
, the carbon atom shares its two electrons with two electrons of each oxygen atom and forms double bond with it. Thus, total pairs of electron to be shared by the atom of the molecule is two.
Answer: There are many relationships between the organizational levels of the environment. All of them compliment each other in order to make everything work.The biosphere is what puts everything all together. It is were all live resides. The community,population and organisms are all in the biosphere. The organisms become the population and then the population becomes the community from all the little organisms around. All of these live in biomes and ecosystems. In those areas is where the population and communities live from all the organisms around. Without the biomes and ecosystems there would be no communities nor population and especially no organism's because there'd be no place to call home.
An example of a density-dependent factor is food. Without food the population will die due to starvation. With food the population will strive. A density-independent factor is a disease. The disease will kill of the whole population no matter it's size.
In primary succession is when a newly untouched habitat is occupied. For example a newly grown plant. This plant will soon be taken over by an insect as its temporary home. Once the plant dies the insect leaves. Then the remains of the plant become secondary succession as it is taken over by for example worms in the soil.
Explanation:
The larynx is an organ in the top of the neck involved in breathing, producing sound and protecting the trachea against food aspiration. The larynx houses the vocal folds, and manipulates pitch and volume which is essential for Phonation. Hope this helps :)
