The paragraph describes mitochondria and chloroplasts. WHICH sentence in the paragraph provides the strongest evidence for the e

ndosymbiotic theory of the origin of eukaryotes?
(A) Mitochondria and chloroplasts are organelles of eukaryotic cells. (B) Mitochondria are involved in energy generation and are present in almost all eukaryotic cells. (C) Chloroplasts are involved in photosynthesis and are found primarily in plant cells. (D) In both organelles, reactions involved in the transfer of energy take place along the organelle's folded inner membrane. (E ) Both organelles can direct their own replication by splitting through a process similar to binary fission.

The answer is; E

This shows that these organelles were once free-living organisms  with their own mechanisms for reproduction which they have retained even after years of symbiotic relationship with the higher organisms. During their duplication, they also replicate their own DNA. Their DNA does not have histones (as opposed to the DNA in the nucleus of their host eukaryotic cell) similar to that of simple organisms such as bacteria.

Human caused reductions of biodiversity, include pollution, invasive species, and overexploitation.
Andrew [12]

Answer:

True

Explanation:

Development, together with globalization, drove severe changes at a global level. The natural and original environments suffered from these effects and still are.

Human beings have constantly been altering the natural ecosystems and causing irreparable damages to nature. For many decades, development involved society and technology advance over new areas unpopulated by humans.

<u>Some</u> of the principal human activities responsible for biodiversity loss are

  • the uncontrolled use of unrenewable resources,
  • overexploitation of renewable resources;
  • land destruction for the mining industry, farming and cattle industry, buildings, and other infrastructures;
  • the unplanned advance of cities, and opening of new roads to connect those cities.  

All of them involving

  • deforestation and fragmentation of natural landscapes;
  • water, air, and soil pollution,
  • species loss, and reduction of biodiversity.

With globalization, transport around the world became normal. And when traveling around the world, new species are intentionally or unintentionally transported too. When these species, of animal or vegetable origin, get established in a new area, they overgrow to the point of turning invasive.

Invasive species are uncontrollable and cause severe damage in native endemic species by competing for resources. The whole ecosystem structure changes.

But there are some background glitches in the system that are the principal responsible for all the mentioned activities. Some important aspects are lacking

  • The respect for nature,
  • People´s education at different levels to care and protect wildlife,
  • Interest in keeping ancestral knowledge,
  • Planning and previous environmental impact studies,
  • Policies to control human activities,
  • Caring involved government.

If, as a society, we lack these aspects, the possibilities of changing our impact on nature are far away.
