Reduce!<span> Buy and use less stuff. This is the best way to conserve natural resources. For example, it takes one ton of raw materials from the earth to make one laptop computer! We can also pay special attention to reducing the amount of non-renewable resources we use. For instance, by reducing our use of non-renewable oil and coal to give us energy and electricity, we can make less air pollution. Instead, we can get energy from the sun, the wind and the ocean's tides to heat our homes and light our rooms. These sources of renewable energy don't create pollution and they will never run out! We can also look for different natural resources to use so that we don't use up too much of one kind. For example, we can make tree-free paper out of plants like kenaf, bamboo, and hemp instead of trees! Using tree-free paper is much better for our forests and all the animals that depend on a healthy forest in order to survive.</span>
Answer:
A. They contain their own DNA
Explanation:
Mitochondria is a eukaryotic cellular organelle which is thought to be evolved by the symbiotic relationship between the prokaryotes and the proto-eukaryotes.
The mitochondria were once a free-living prokaryote which during the course of evolution was engulfed by the proto-eukaryote. They formed the symbiotic relationship with each other and the prokaryote evolved into the mitochondria.
There are many pieces of evidence which suggest the endosymbiotic hypothesis one of which is provided in the option is that they contain their own DNA just like the prokaryotes that is one circular DNA present in their cytoplasm not enclosed by the
Thus, Option-A is correct.
