<span>Amino acids are
weak acids that have at least 2 pka values. They have two titratable protons
that composed of alpha carboxyl (-COOH) and alpha amino (-NH3+), but some amino
acids have a third titratable protons with ionizable groups in the R side chain.
In addition, the structure of amino
acids in peptides and proteins are determined by the charges of the titratable
group and by the R group. </span>
The formula for photosynthesis is 6CO2 + 6H2O + light energy = C6H12O6 + 6O2.

14.The point is, without the respiratory system your blood would be useless. The circulatory and respiratory systems work together to circulate blood and oxygen throughout the body. Air moves in and out of the lungs through the trachea, bronchi, and bronchioles.
15.The skeletal system provides the framework for the body. While the muscular system consists of the soft tissue that lies over and supports the skeleton.
16.A biome is a community of plants and animals that have common characteristics for the environment they exist in.
18.Climate is the most important abiotic factor affecting the distribution of terrestrial biomes. Climate includes temperature and precipitation, and it determines growing season and soil quality.
19.Climate is the weather of a place averaged over a period of time, often 30 years. Weather is the day-to-day state of the atmosphere, and its short-term variation in minutes to weeks.
Answer:
In science, this is false. Powers of ten are the references to either scientific notations or measurements when comparing atoms in chemistry.
