The appearance of banded iron layers in the rock record between 1.08 and 3.8 billion years ago reflect the alteration of oxygen-rich and oxygen-poor conditions in the ocean at that time is True.
<u>Explanation:</u>
Banded rocks have layers of iron oxide and cherts that contain silica. The layer containing iron oxide has a dark color and the chert layer is red in color. Haematite and magnetite are usually the iron oxides that make up the banded rocks.
Banded rocks were formed by the reaction of iron in the oceans with the oxygen produces by photosynthetic bacteria in the ocean. The reaction caused the formation of iron oxides and their precipitation as Banded iron formations.
The presence of free oxygen is crucial for the formation of banded rocks and the formation reduced drastically after 1800 mya period when atmospheric oxygen availability was reduced. Banded rocks represent the oxygen rich and oxygen-poor condition of the ocean at that time.
The Chloroplast possess their own DNA. This organelle has green orpiment called Chlorophyll.
Density is a physical property of substances that compares the relationship between volume and mass. Density is affected by temperature because as temperature increases so does the kinetic energy of the particles. Please give me the brainliest answer?
:) Hoped this helped!!! Have a good day!!! <3
Answer: Aspergillus
Explanation:
Aspergillus is the fungal species which is highly aerobic in nature. It is found in the oxygen rich environment. This fungal species grows as molds typically over the substrate, as a result of high oxygen tension. The molds are toxic in nature. It grows over certain fruits, vegetables like apricots, peanuts, onions and grapes. It is the common contaminant of food. It is responsible for causing liver cirrhosis.
On the basis of the given situation this can be said that Steve is infected by Aspergillus.
