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.
Answer:
Option (4).
Explanation:
Endomembrane system is may be defined as the sysytem that divides the cell into functional compartment or organelle. The organelle of endomembrane system are nuclear envelope, rough and smooth endoplasmic reticulum, golgi body, lysosomes, vesicle and plasma membrane.
Endomembrane system contains different membranes of cell organelle are suspended in the cytoplasm of the eukaryotic cell. Tge endomembrane system helps in synthesis, packaging and export of important proteins and molecules.
Thus, the correct answer is option (4).
The lining of the spinal cord is called the "Dura". Dura is a meninge which is the top layer of protective covering for both the brain and the spinal cord.
Answer:
The correct option is<em> "The rate of photosynthesis decreased in the dark, thus the elodea used less CO2. The elodea and snails continued to produce CO2 through cellular respiration, raising the level of CO2 in the tube, causing the solution to become more acidic (yellow)."</em>
Explanation:
The process of photosynthesis is dependent on light energy. As the test- tubes were kept in the dark hence, the rate of photosynthesis was minimal. Less carbon dioxide was used for this process by the elodea.
The process of cellular respiration is not dependent on light. Hence, both the snail and elodea will carry out respiration and release carbon dioxide. Due to this carbon dioxide, the solution will turn acidic.
Answer: A
Explanation:
Exponential growth simply means a rapid increase in size and a constant growing rate
