Because cellulose is required for the stem growth as cellulose is the main constituent of the cell wall and also provides toughness to the stem.
When less sunlight is in those months the photosynthesis also lowers, resulting in the use of stored energy i.e starch. Hence the starch level decreases.
Explanation:
Cellulose is required for the growth and toughness of the stem. During spring the budding and growth is fastest in plants hence supply of cellulose increases.
The starch is the energy stored in plants. It is a polymer of glucose. When sunlight decreases in some months the rate of photosynthesis lowers down and plant starts using the stored form of energy ie. starch, required for various physiological activities and growth of the plants. This is the reason the starch level decreases in plants sometimes.
A. Because saturated fatty acids are the ones with no double bonds
Answer:
Transgenic
Explanation:
Recombinant DNA technology is used to make transgenic organisms. Genetic material from one specie is inserted into the genome of another thus modifying its characteristics. There are several ways of doing this including electroporation and transduction. This process is referred to as genetic engineering.
B. Oases are sourced by springs and are regions where groundwater intersects the land surface.
Explanation:
The only true statement is that oases are sourced by springs and regions where ground water intersects the land surface.
- Oases are water bodies found in desert and arid areas.
- They are usually surrounded by fertile patches of soil.
- Oases forms when the land surface intersects the water table.
- They can also be fed by temporary surface water from nearby rivers.
Fossil remains have suggested that the region of the Sahara desert was once a lush green tropical region.
In present day, it is a desert with huge underground water reserves in aquifers.
