Describe how our lives would be different if the lightbulb had never been invented.

Biology
1 answer:
Marrrta [24]3 years ago
5 0

Answer:

If the light bulb had never been invented, we would use natural sunlight as light during the day and fire or candles when we cannot see the sun. Since the light of candles is rather dim, most people would also sleep and wake up early, with the sun. The streets would be darker at night, even in urban areas.

Many other inventions that use the light bulb may not have been invented, or would be different. For example, our computer screens and television screens are forms of small light bulbs. Car headlights use light bulbs as well.

The more ________________ the homologous structure, the more likely they _______________ shared a common ancestor
Natali [406]

The more numbers of the homologous structure, the more likely they have recently shared a common ancestor.

Explanation:

Homologous organs are defined as those organs which do have different functions but a similar basic structure which denotes the divergent evolution. Homologous organs are seen in species that are very close to each other which are more related with each other in terms of evolution. For example, a bird is more close to each man than a fish, so do share more homologous organs common to man than fishes do. Examples of the homologous organs are hands of human and wings of birds. They have same basic structure like skeletal structure which is humerus, radius, ulna, carpals, metacarpals and phalanges. They are similar in structure but have different functions like flying in birds and gathering food in humans.

State one effect the reintroduction of the
Natali [406]

We can confirm that the reintroduction of the wolf to the ecosystem would most likely cause a decline in the population of coyotes.

<h3>Why would this cause a decline in the population of coyotes?</h3>

The wolf, in most ecosystems, is considered to be the top predator. This means that it will also hunt and consume the coyotes. This alone would cause a decline in the coyote population as they now have an additional predator hunting them. Also, the wolves would be competing with the coyotes for food sources, furthering the impact on the coyote population.

Therefore, we can confirm that the reintroduction of the wolf to the ecosystem would most likely cause a decline in the population of coyotes.
