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
Answer:
incorrect
Explanation:
diffusion is the movement of particles <u>with</u> the concentration gradient
for example: over time, food coloring and water mix and become one same color.
Answer:
A
Explanation:
I think I am not sure but ya
Carbohydrates and lipids are both sources of energy. The breaking of carbon and hydrogen bonds on carbohydrates and lipids release energy for use by the cells.
Using the gas pedal analogy, the proto-oncogene would be an accelerator since they promote cell division and
deregulate apoptosis, while tumor suppressor would
be the brakes since they constrain the progress of the cell
cycle and induce cell apoptosis. An
oncogene is, therefore, when the accelerator
is stuck in down position and the brakes are not working.
