In the normal course of evolution and adaptation, what is the most likely way for wings to develop in a tetrapod (four-limbed or

serious [3.7K]

The correct option is this: The forelimbs (or possibly hind limbs) will be used for the new purpose of flight. This new function will arise through many gradual steps, and there will be aspects of the wing that reflect its history and are not perfectly suited for flight.

Adaptation refers to the physical or behavioral traits that an organism develop in order to enhance its suitability to its environment. Evolution on the other hand is always brought about by natural selection; organisms that are well adapted to their environments are naturally selected to survive, reproduce and pass their beneficial traits to their offspring. This is a gradual process that occurs over a long period of time.

For wings to develop in a four limbed organism, the organism has to start using the hind or the fore limbs for flight (New adaptive behavior). The genes that support this new behavior will be passed to its offspring and subsequent generations over a long period of time, until the wings are perfectly suited for flight.

According to the U.S. Department of Energy, a typical home in the United States uses approximately 900 kWh of electricity per mo

guapka [62]

Based on the energy generated by the power plant annually, the number of households the plant can support:

if energy usage is 10,800 kWh/year = 365000 households
if energy usage is 24000 kWh/year = 164250 households

<h3>What is electrical energy?</h3>

Energy is energy that is due to movement of electrically charged particles.

Electrical energy is used in homes for many purposes.

Electrical energy is sold in units of kWh.

Data provided:

Capacity of power plant = 500 MW

Capacity factor = 0.9

Average annual household energy usage = 10,800 kWh/year

Energy generated in a year = 24 × 365 × 0.9 × 500 MW = 3,942,000 MWh/year

3,942,000 kWh/year = 3,942,000,000 kWh/year.

Number of households the power plant can support = 3,942,000,000 kWh/10800 = 365000 households

Number of households the power plant can support is 365000 households

If monthly electricity usage increases to 1,200 kWh

In a year, energy usage = 1200 × 12 = 24,000 kWh/ year

Number of households the plant can support = 3,942,000,000 kWh/24,000 = 164250 households

Therefore, based on the energy generated by the power plant annually, the number of households the plant can support:

if energy usage is 10,800 kWh/year = 365000 households
if energy usage is 24000 kWh/year = 164250 households
