Over time mutations occur. If the mutation is null (no effect) or beneficial, the organism will go on to reproduce and that mutation will carry into the next generation. Faulty mutations that cause harm will not likely be carried forward.
So, several generations later you have some level of change to the original sequence.
Biodiversity is of great importance in order to maintain stable ecosystems. An ecosystem is a group of life forms that live together in a balanced and stable community. If there is a sudden change in that community’s environment, the balance of the community may change which may cause it to be destroyed.

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
