Because they need to make a lot of light
The right answer is D.
The effectiveness of BT-Corn compared to conventional insecticide treatment is very much higher:
* The plant itself produces the toxin that blocks the digestion of or target insects: the entire plant is protected where a treatment (out of neonicotinoids, very expensive and reserved to the seed treatment) allows only a protection of surface and must be renewed several times.
* The selectivity of the treatment is very superior: each variant of the BT molecule targets only a family of insects but we do not know the impact of their cumulative effects in the environment.
Answer:
2.ln the analysis you calculate heart rate average over 15 second and instaneous
Answer:
2.956 × 10 ⁻¹¹ g
Explanation:
The mean concentration of hemoglobin in red blood cell = 0.34 g/ml
average volume of a red blood cell = 87μ m³ where 1 μ m³ = 1 × 10 ⁻¹² ml
average volume = 87 × 1 × 10 ⁻¹² ml = 87 × 10 ⁻¹² ml
weight of hemoglobin contained in an average red blood cell = 87 × 10 ⁻¹² ml × 0.34 g/ml = 2.956 × 10 ⁻¹¹ g
They use there fins to propel themselves
