<h2>Birch bolete and birch</h2>
Explanation:
According to the given information it can be inferred that these two species require a similar soil pH
Fungus and tree shows an interdependence on each other
Fungus cannot make their own food hence is dependent on trees for its food requirements whereas in return helps trees in their biochemical processes
This shows a symbiotic relationship where both trees and fungus are being benefited from each other
Fungus grows on the roots of birch trees hence their soil requirement will be same

Answer No 1:
The correct option is c) Both mitochondria and chloroplast contain DNA that is different from the nucleus.
Explanation:
The theory of endosymbiosis proposes that all the eukaryotic organisms have arisen from prokaryotes. This theory proposes that organelles such as DNA and nucleus were once prokaryotic cells. These smaller prokaryotic cells were engulfed by the larger prokaryotes which gave rise to eukaryotes eventually. These organelles possess their own DNA which is different from the DNA of the nucleus.
Answer No 2:
The correct option is C) aerobic organisms
Explanation:
The scientists propose that the initial conditions of the Earth were not favourable for supporting aerobic life. Scientists propose that photosynthetic organisms like cyanobacteria released oxygen into the environment which made the life of aerobic organisms possible on Earth.

Explanation:
Spontaneous generation can be described as the generation of life from non-living things. Some scientists proposed that living organisms are formed by non-living things.
Answer;
Seedless plant.
The fossil of a plant reveals that it produced spores that were used for reproduction. It was a seedless plant.
Explanation;
-Seedless vascular plants are plants such as fern and horsetails, liverworts, mosses; which contain vascular tissues, but do not produce flowers or seed.
-These plants reproduce using haploid , unicellular spores instead of seeds.
-These plants have life cycles with two distinct stages; one in which spores are produced and one in which sex cells are produced.
Answer:
Pleistocene Epoch
Explanation:
Modern humans coexisted with woolly mammoths during the Upper Palaeolithic period when the humans entered Europe from Africa between 30,000 and 40,000 years ago. Before this, Neanderthals had coexisted with mammoths during the Middle Palaeolithic, and already used mammoth bones for toolmaking and building materials. Woolly mammoths were very important to ice-age humans, and human survival may have depended on the mammoth in some areas.
The Pennsylvania period, Precambrian period, and the Palezoic Era all existed millions of years before mammoths and humans.
