Original source of sand was from rocks rubbing up against each other in the ocean and the current of water in the ocean bringing them to land.
Answer: Very unlikely
Explanation:
Generally, point mutation can be easily reversed by another point mutation, so
before any changes occur in the amino acid sequence, it would have been corrected.
However, when point mutation occurs within the protein coding region of a gene it may results in the change of a single nucleotide to cause the substitution of a different amino acid (which renders the protein non-functional) as in the case of sickle-cell disease.
And this kind of point mutation is specifically called Missense mutation.
Above all, because point mutation is easily reversible, it is very unlikely to change the amino acid sequence of a protein
Answer:
chromosomes of the sex are doubled
Explanation:
Answer:
Phenotype.
Explanation:
Genotype may be defined as the genetic constituent of the organism. Phenotype is the physical appearance of the organism that can be modified by the organism's genotype.
The tall pea plant (TT) and (Tt) constitute the same phenotype as both the genotypes are responsible for the appearance of the tall height of the plants. The phenotype of the plant is controlled by its genotype.
Thus, the correct answer is option (B).
In a cladogram the tiny indentations along the bottom line is an evolution or change and every organism after the indentation on the bottom line has it and every organism before the indentation does not
