Why is the fossil record biased

Biology
1 answer:
svetoff [14.1K]2 years ago
6 0

Information in the fossil records are incomplete, scientists are left with certain biases concerning fossil preservation. Fossils are the preserved remains of organisms that are found in rocks. They give clues to how the earth has evolved in geologic past, and the nature of organisms that lived during that period in time.  A lot of biases are known with fossil preservation as a geologic record might not tally with the phylogenic relationship developed by biologists.  Some fossils can become lost in the geologic record due to the dynamic nature of our planet. Earth materials can be eroded and weathered causing preserved fossils to be lost and exposed.  Some organisms are naturally favored due to their physiology to be preserved as fossils in the geologic record. Others would be lost. This makes records of life in preserved as fossils highly subjective.

Hope this helps, good luck!

Robert, an aspiring scientist in a biology class, wanted to conduct a study on the effects of cigarette smoke on the web-buildin
Evgesh-ka [11]

Answer:

<em>The statement that is incorrect is :</em>

<em>Robert wanted to see if his theory was true that cigarette smoke will influence web-building in spiders.</em>

Explanation:

A theory can be described as a descriptive explanation of a phenomenon which is supported by valid experiments and careful examination of facts. As Robert, has not conducted any experiments nor has proved his study with reference to facts, hence it cannot be considered as a theory.

Robert wanted to see if his observation was true that cigarette smoke will influence web-building in spiders will be the correct statement that could be used.

A circle with radius of 9 cm sits inside a circle with radius of 11 cm.
malfutka [58]

Answer:

125.6

Explanation:

Area of a circle = πr^2

Area of circle 1 = 3.14 × 11 × 11

=379.94cm^2

Area of circle 2= 3.14 × 9 ×9

=254.64cm^2

Area of a shaded region

=379.94cm^2 - 254.64cm^2

=125.60cm^2

How might biodiversity in Area 1 change if the new bird species ate small mammals, lizards, and toads?
zmey [24]

Knowing that Biodiversity is the variety and variability of life on Earth. Biodiversity is typically a measure of variation at the genetic, species, and ecosystem level. Terrestrial biodiversity is usually greater near the equator, which is the result of the warm climate and high primary productivity. The ecosystem will change if a new species is introduced to an unfamiliar ecosystem. If a new species of birds were to eat another animal that was supposed to be eaten by another. The food chain of the ecosystem would be changed drastically. Aka, it might make the lizards go extinct, and can possibly become abundant. Aka, overpopulating and creating havoc within the ecosystem. Thus, causing imbalance.
