Brrunno [24]3 years ago

Explanation:

The impact of humans

The Earth is the source of all the resources we need, such as metals, plastics and fuels. Humans are very successful living things. We compete with other organisms for many natural resources. These include:

land (for farms, buildings and roads)

water (for drinking, watering fields, and industry)

The world’s human population is increasing, and this means that we are using more resources all the time.

Population growth

The human population in the year 1800 was about 1 billion, and now it is more than 7 billion (more than 7,000,000,000).

Deforestation

Humans have been cutting down trees for thousands of years. We do this to clear land for farming and building, and for wood to use as a fuel or building material.

Forestry is sustainable as long as forests are allowed to replace themselves, or are replanted after felling, but often this is not done. The result is that the world’s forests are steadily shrinking.

The slideshow maps show the loss of forest across the world over the last 10,000 years:

Pollution

We produce waste whenever we make or transport objects and substance. Waste materials include:

household and industrial rubbish

chemicals from industrial processes

smoke from burning fuels

harmful gases from burning fuels

They damage the environment and are a waste of resources.

Which is part of the endosymbiont theory? Autotrophic prokaryotes evolved into mitochondria. Eukaryotes engulfed photosynthesizi
MrRa [10]

Answer:

The correct answer is eukaryotes engulfed photosynthesizing prokaryotes

Explanation:

The endosymbiotic theory or symbiogenesis is an evolutionary theory that traces the origin of eukaryotic cells from prokaryotic organisms. It explains that some of the organelles (Mitochondria and Chloroplasts) in eukaryotic cells evolved from free-living prokaryotic microbes which were ingested or engulfed. The ingested prokaryotic cells survived within the organism and developed a symbiotic relationship.

According to the theory, chloroplasts was formed when eukaryotes engulfed photosynthesizing prokaryotes and mitochondria was formed when bacteria capable of aerobic respiration were engulfed.
