sweet-ann [11.9K]

Answer:

Prophase is the first phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells.

Metaphase is a stage in the cell cycle where all the genetic material is condensing into chromosomes.

Anaphase is the stage of mitosis and meiosis in which the chromosomes move toward the poles of the spindle.

Telophase is the final stage of mitosis and of the second division of meiosis in which the spindle disappears and the nucleus reforms around each set of chromosomes.

Cytokinesis is the division of cells after either mitosis or meiosis I and II.

A state is looking to reduce the cost of transportation, which uses 7.10×10^14 BTUs per year. Currently the cost of 10^6BTUs is
Ilia_Sergeevich [38]

Answer:

$ 284 million dollars

Explanation:

If the energy usage of all transportation is 7.10 × 10¹⁴ BTU per year, if their efficiency is to increase by 20%, The new energy usage will be (1 + 20/100)7.10 × 10¹⁴ BTU per year = (1.02)7.10 × 10¹⁴ BTU per year = 7.242 × 10¹⁴ BTU per year.

The energy saved is thus the difference 7.242 × 10¹⁴ BTU per year - 7.10 × 10¹⁴ BTU per year = 0.142 × 10¹⁴ BTU per year.

Since 10⁶ BTU costs $ 20.00, then,

0.142 × 10¹⁴ BTU costs 0.142 × 10¹⁴ BTU × $ 20.00/10⁶ BTU = $ 2.84 × 10⁸ per year = $ 284 million dollars

So the state saves $ 284 million dollars in one year
