Answer: d. none of the other answers
Explanation:
Enzymes that turn chemical energy into mechanical work are molecular motors.
There are three main components of cytoskeleton including microtubules, actin filaments and Intermediate filaments. Only actin filaments and microtubules carry the motor-driven transport on the cytoskeleton.
The most important feature of intermediate filaments is to provide the plasma membrane with mechanical support where it comes into contact with the extracellular matrix and other cells.
Unlike microtubules and microfilament , intermediate filaments are not involved in motility of the cells, hence do not associat with molecular motors.
Hence, the correct option is d.
Scientific argumentation is a method and process used by scientists as guide to their research activities.This way, scientists ,together with their colleagues, get to set limitations and identify weaknesses in their researches. This also allows them to refine their work and improve certain areas in their results.
The answer is A. Pollutant
60 centimeters (2 ft 0 in) to over 260 cm( 8 ft 6 in)
Answer: Option D) China
Explanation:
From the picture provided, China and USA contributes above 5.000.000 ( In thousands of metric tons) of carbon dioxide emissions.
And since carbon dioxide has been implicated in the emergence of global climate change, both countries are leaders in the emission.
Thus, China is the right option
