Answer:
TRUE
Explanation:
The trees are the primary producers that produces the food on which the consumers are dependent. This forms the base of the ecological pyramid for both energy as well as biomass.
In any biological condition, it can be observed that during its ecological succession from one trophic level to the next, almost 90% of its total energy is lost, and only 10% of its energy is transferred to the successive trophic level.
Similarly, biomass is also comparatively higher in producers like plants and trees than in any other trophic levels.
Thus, the given statement is True.
Answer:
The expected age for one of the passengers on the train is 7.
Explanation:
Answer:
Generic drugs tend to cost less than their brand-name counterparts because generic drug applicants do not have to repeat animal and clinical (human) studies that were required of the brand-name medicines to demonstrate safety and effectiveness.
Generic pharmaceuticals are significantly cheaper than name brand ones because generic pharmaceuticals are not protected by patent law, so the lack of barriers to entry and increased competition keep prices down.
Also, the makers of generic drugs do not have to cover the cost of developing and marketing a new product.
Sin(30°) =1/2 0.5
cos(30°) = (√3)/2
Note that the sin of an angle is equal to the cos of the complementary angle:
sin(60°) =cos(30°) = (√3)/2 since 30+60 = 90 (compl. angle)
The answer fam is........ D)
