Answer: Precipitation

Grasslands are characterized as lands covered by grasses rather than large shrubs or trees. Grasslands are found in regions which receives rainfall that are not enough for the growth of forests. Desert covers about one fifth of the Earth's surface and occur where rainfall is less than 50 cm/year. Rainfall are least frequent in deserts as compared to grassland. The desert-grassland boundaries can change as a result of precipitation. The fate of land form of boundary will be dependent upon precipitation. As, if the boundary receives moderate or sufficient rainfall to grow vegetation then it will be included in the grassland and if the boundary receives no or scanty rainfall then boundary will be included in desert region.

UNO [17]

Answer:

<u>-blue and red light</u>

Explanation:

Plants produce sugars or carbohydrates during the process of photosynthesis. They absorb light energy from the electromagnetic spectrum with pigments within the thylakoid membrane, like chlorophyll a, chlorophyll b.

Chlorophylls are made of ringed molecules chlorine, a hydrogenated form of porphyrin with a magnesium ion bonded to four atoms of nitrogen. Chlorophyll a shows the most absorption of red light  (642 nm) and blue light (372 nm); while chlorophyll b shows the most absorption at 626 nm and 392 nm.  

Different types of chlorophyll sidechains change the molecules' absorption ranges; A's methyl group is bound at carbon 7,  B's aldehyde (CHO) ring is bound at carbon 7.  Both absorb light from orange-red and violet-blue wavelengths. As such, the best light wavelengths for photosynthesis are within the blue and red wavelengths (425–450 nm) and (600–700 nm).

The correct answer would be D.

After many generations, only those with genes suitable to live in harsh environments can live. These genes are passed onto their offspring and then we see a rise in antibiotic resistant strains of bacteria such as Methicillin Resistant Staphylococcus Aureus (MRSA).
