Ecosystem is correct...
please vote my answer brainliest.thanks!
The answer is most likely: 'with an abundance of plant life without oxygen in the atmosphere '. The atmosphere contained almost no free oxygen during the Archean. It does not appear as if this epoch had an abundance of plant life, but rather mats of single-celled photosynthesising cyanobacteria. So I am not completely sure that either of the given choices are correct.
Iguanas are ectothermic, Kangaroos use osmoregulation.
Answer:
7%.
Explanation:
The recombinant progeny might occur due to the exchange of genetic material between non sister chromatids known as crossing over during the meiosis.
The chromosome sequence is DABC. A and B distance is 4 map units, B and C is 2 map units, B and D is 5 map units. The distance between A and D is 1 map unit that can be calculated by subtracting the distance between BD and AB ( 5-4). The CD map distance can be calculated by adding the distance between AD, AB and BC ( 1 + 4+ 2). The recombination frequency is equal to distance between them is 7%.
Thus, the answer is 7%.
Higher mass bc the hotter it it the higher the mass will be
