What are Air Masses: They large volumes of air that have generally the same temperature and pressure.
How they work: One is heated by an electrical current, the other is not. As air flows across the heated wire, it cools down.
Example of an Air Mass: The air masses in and around North America include the continental arctic, maritime polar, maritime tropical, continental tropical, and continental polar air masses. Air is not the same everywhere.
Fact: Unstable air masses have different temperatures and pressures.
How they are formed: An air mass forms whenever the atmosphere remains in contact with a large, relatively uniform land or sea surface for a time sufficiently long to acquire the temperature and moisture properties of that surface.
*** <em>The Earth's major air masses originate in polar or subtropical latitudes.</em>
Answer: Physically plant's origin chloroplast differs from animal's origin mitochondria.
Explanation:
Physically, chloroplasts contain chlorophyll and take part in photosynthesis and mitochondria lack chlorophyll and take part in cellular respiration. Furthermore, the inner membrane of chloroplast forms thylakoids whereas inner membrane of mitochondria folds to form cristae.
Acccording to the genome, The complete nucleotide sequences of the chloroplast (cp) and mitochondrial (mt) genomes studied presents tha the smaller chloroplast genome contains more genes with a 72% coding sequence, and the larger mitochondrial genome have less genes with 12% of coding sequence. The hypothesis concerning the origin of the organelles genomes is known as the endosymbiotic hypothesis, which concerns the origin of mitochondria and chloroplasts.According to this hypothesis, these organelles originated as separate prokaryotic organisms that were taken inside a primordial eukaryotic cell.
A primary active transport process is one in which <span>molecules move through transport proteins that have been activated by ATP.
</span><span>Primary active transporters, such as the sodium-potassium ATPase (or pump), are activated when ATP is hydrolyzed. This activation allows for the transport of solutes across the plasma membrane against concentration gradients.</span>
The water from a trough and the temperature outside would be abiotic factors. the grass it grazes on or a cowbird picking bugs off of it would be biotic factors (for future reference, abiotic factors are caused by nonliving things, and biotic factors are caused by other organisms)
We basicly can't digest them as it has cellulose and we can't digest cellulose .acc. to me in olden days early men used to survive with raw green plants because the cellulose is digested by our appendix but slowly as we stopped eating raw green plants the appendix lost it function tooo. so we should always eat a selective plant like lettuce
