Explanation:
1. The father is a non-roller, as was given in the question. Remember that a phenotype is the physical trait displayed by an organism.
2. In order for the father to be a non-roller, the recessive non-roller allele would have to be expressed. In order for this to happen, he would need two recessive alleles.
3. The gene for tongue rolling is dominant, so if the mother is heterozygous (she has one dominant allele and one recessive allele), then she will be a tongue roller.
4. The mother has a dominant allele and a recessive allele.
5. 50% of the offspring have the Rr genotype and 50% have the rr genotype. This means that there is a 50% of having a tongue-rolling child and a 50% chance of having a non-rolling child.
6. Because the possibility of the offspring having either genotype is 50/50, the ratio would be written as 1:1. Both outcomes are equally likely.
7. Because the possibility of the offspring having either phenotype is 50/50, the ratio would be written as 1:1. Both outcomes are equally likely.

Answer:
Nucleic acids are not essential for nutrition
Explanation:
Nucleic acids are a group of biomolecules that functions in the storage and transmission of genetic material within living organisms. DNA is one of the nucleic acids found in nature.
DNA is a storage molecule i.e stores genetic information. It does not store energy, hence, it doesn't serve the purpose of providing nutrient in a cell. Therefore, DNA will not be included on the nutrition labels for strawberries because they are not essential biomolecules for nutrition.
Cardelia is visits the national aquarium in Washington D.C., and watches the seahorses swim with various fish. She begins thinking about the human brain, and remembers that one major structure, which is important in the formation of new memories, gets its name because it is shaped like a sea horse. The brain structure is a. Hippocampus. Long term memory formation gets crippled when hippocampus gets damaged. The movie 'Memento' is based on this fact.
Answer:
The answer to your question is C. All of the fossils show similar structures to that of the modern horse.
hope this helps! plz mark brainliest! :)
The species will make which will cause overpopulation
