Answer:
Greenhouse gases play an important role in controlling the overall temperature of the earth. The slight increase in the composition (in ppm / ppb) of these atmospheric greenhouse gases such as CO2, water vapor, methane, CFC, etc. can lead to a subsequent increase in the average global temperature, which may be sufficient. Enough to melt the ice in Antarctica.
Thus, as the sea level rises, the temperature rises.
Answer:
For a couple of decades, biologists knew the nucleus contained DNA and proteins. The prevailing opinion was that the genetic material was proteins, and not DNA. The reason for this belief was that proteins are more complex than DNA. This is because: <u>proteins have a greater variety of three-dimensional forms than does DNA.</u>
Explanation:
Protiens have a greater variety of three dimensional forms than does the DNA
Protiens contain one or more polypeptides which are usually arranged in one of the following structures :
1)Primary structure
2) Secondary structure
3) Tertiary structure
4) Quaternary structure
These structures are maintained by Hydrogen bonding , Hydrophobic interactions , Disulphide bonds and ionic bonds )
DNA on the other hand is a double stranded molecule containing only hydrogen bonds between the nitrogenous bases and the covalent bonds within nucleotides. It is much simpler than protiens.
Coyote brush is a glabrous, sticky, common, shrub that grows in Oregon, California, and Baja California. The adaptations that the coyote brush possess that helps it to survive in the chaparral biome are; (i) its ability to take on a different shape or growth pattern based on its environment, (ii) its large root system, and (iii) its fire resistant leaves. The stems of the shrub are able to erect any branches spreading or ascending based on its habitat. When the shrub is affected by winds or salt spray, it grows low on the ground and spreads on ridges and plains.
Answer:
" Under cultivation, the A horizon broadly aligns with the topsoil and the B with the subsoil. The parent material below these is the 'C' horizon and where there is an underlying unweathered rock layer, often known as bedrock.
Explanation:
Answer is D. When the concentration of the substance is lower outside he cell than inside the cell.
