Option B

Explanation:

The formal study of fossils, its collection and documentation started in 1700s during the period known as “Age of Enlightenment” It was during this time period that scientist noticed rock fossils and started making fossil collection. During the 1800s, areas with  rocks fossils were studied and compared.  

Further,  Charles Lyell and Charles Darwin showed strong connection between biological evolution and geological evolution of planet earth. Hence, the earlier traces of fossils i.e before a certain period could not be studies due to late pioneering of fossil based evolutionary science. It is also due to limitations with radioactive dating

svlad2 [7]

Answer:

No

Explanation:

Both A alleles and B alleles are dominant over the O alleles. This means that both parents must have an O allele present to even have a chance of having a child with type O blood. Lets say the mother has type O blood with the father having type AB blood. The possible combination would be: AO, BO, AO, BO. The punnett square should look like this:

What are roles of producers, consumers, and decomposers in an ecosystem​
Daniel [21]
An organism that obtains energy and nutrients by feeding on other organisms or their remains. A food web is a model of the feeding relationships between many different consumers and producers in an ecosystem. Without plants (the primary producers) consumers and decomposers would not be able to live. Producers always start every food chain. A consumer, also called a heterotroph, is an organism that cannot make its own food. It must eat producers or other organisms for energy.
