Answer:
C) Underwater organisms in dry land
Explanation:
The listed options are:
A) Large number different-sized footprints.
B) Plant but no animal fossils.
C) Underwater organisms in dry land.
D) Straight teeth buried below curved teeth.
Discovering fossils of underwater organisms in dry land <u>demonstrates that thousands to millions of years ago, there was a body of water such as an ocean, lake, or river in an area that is now dry land.</u> This gives important insights into what was the Earth's climate at that epoch and how it has changed throughout time.
This discovery could allow researchers to study what the conditions were at that time and why that body of water dried out. Moreover, it could lead to answers of the reasons behind the extinctions or evolution of some underwater organisms.
Answer:
Bones. They are vertabrates, which means they have a backbone
Explanation:
Fish, reptiles, amphibians, birds and mammals all have bones
The different forms of a gene are called alleles
An integrated explanation supported by extensive observation and experimentation and evaluated by the peer review process is called a scientific theory.
Peer review process is the system of analyzing and assessing the written manuscript before it is published in any journal. The process is performed to evaluate the dignity, originality and the significance of the manuscript. There are around 10 steps in the review process.
Scientific theory is a series of explanations for various facts and observations. The scientific theory should have some relevance, and if possible valid evidences as well. A theory can be proved even with the help of experiments.

Answer: The scientist will perform another investigation in order to find out the role of certain genes in disease resistance.
Explanation-
As per the information given in the question, a mice having mutation in ear depicts same pattern of resistance when compared to another mice having normal ears. This indicates that the genes responsible for resistance are not related to genes that result in ear formation.
Therefore, to find out the effect of diet on disease resistance in rats, the scientist will perform another investigation in order to find out the role of certain genes in disease resistance.
