Question options:
1. developing a hypothesis to explain collected data
2. proving a theory and writing a new scientific law
3. collecting data through observation and measurement
4. observing and experimenting to test a hypothesis
Answer:
2. proving a theory and writing a new scientific law
Explanation:
Providing a theory and write a new scientific law is not a step of scientific investigation. To prove a law a theory, its take many years of research.
There are steps of scientific investigations below,
1. Make an Observation.
2. Form a Question.
3. Form a Hypothesis.
4. Conduct an Experiment.
5. Analyze the Data and
6. Draw a Conclusion.
These step of scientific investigation does not include to write a theory and scientific law.
The difference between an amniotic egg and eggs laid by other animals is : Absence of Membrane ( amnion ) and absence of larval stage
<h3>Characteristics of an amniotic egg</h3>
Eggs laid by amniotes are different from other eggs laid by fishes, amphibians and invertebrates in that they lack a membrane and a larval stage. the shell of the amniotic egg protects the embryo in the absence of a membrane. The shell also allows for the exchange of oxygen and carbon dioxide between the the embryo and the environment.
Hence we can conclude that The difference between an amniotic egg and eggs laid by other animals is : Absence of Membrane ( amnion ) and absence of larval stage

Answer:
A Carries urine to the bladder
B excretes urine out of the body
C stores urine temporarily
D produce urine
Explanation:
The position within the original arginine codon where the point mutation most likely occurred was the second nucleotide. In this case, the mutation was CGA >> CAA.
<h3>Mutations and codons</h3>
A mutation is any alteration in the nucleotide sequence of an organism.
A point mutation is a single base substitution that doesn't change the open reading frame of a given protein.
In this case, the CGA codon encodes for Arginine, whereas the CAA codon encodes for Glutamine, thereby the mutation likely occurred in the second base (C<u>G</u>A >> C<u>A</u>A)
