Basically, macro molecules fall into four classes;
The lipids
The carbohydrates
The proteins
The nucleic acids
The fact that their role revolve around energy production by carbohydrates, energy storage and insulation by lipids, storage of genetic material by nucleic acids and structural support by proteins means this can be equated to the executive arm of the government that deals in provision of social amenity, protection, creation of job opportunities and sustaining a country's culture.
The correct answer is option (A) Variation in the strawberry plants.
When the effect of fertilizer on the growth of two strawberry plants is tested, unavoidable source of experimental error is the variation in the strawberry plants. Variation refers to the deviation or differences from the normal plant which can be due to genetic variation. It is due to change in the DNA sequence. If any one of the two plants being tested show variation, the rate of metabolism differs and changes the growth pattern of the plant. The rate of absorption of water and nutrients is effected which brings change in the growth of the plant and causes an error in the experiment and the result.
Answer:
B
Explanation:
The windward position on a mountain is the side that is bombarded with prevailing winds. These winds are forced upwards into the upper cooler atmosphere by the physical barrier of the mountain. The moisture in the winds condenses forming clouds that precipitate as rain. As the winds descend on the other side of the mountain (leeward side), they have little moisture left. Therefore, the windward side will be rich in vegetation and biodiversity due to higher annual rainfall than the leeward side.
Finches in the Galapagos Island are good example of adaptation because these finches have undergone several variations in their beak shape and form according to their ecological niche.Nov 29, 2017
