The earth's inner core is the innermost layer of the earth. Primarily, it is a solid ball composed of an iron-nickel allow and some other elements, which holds a radius of about 1,220 kilometers.
Answer:
E
Explanation:
Gregor Mendel discovered the principles that governs heredity. In one of his experiments, he discovered that an organism receives two forms of a gene called ALLELE from each parent. He realized that one allele is capable of masking the expression of its variant pair in a gene. He called the allele that masks or is expressed, DOMINANT allele while the allele that is masked, RECESSIVE allele. He termed this principle the LAW OF DOMINANCE.
The above explained law of dominance is what applies in the question here. When the homozygous round allele and wrinkled allele were crossed, the allele for round seeds are dominant over the allele for wrinkled seeds (recessive) i.e. in a heterozygous state (combination of the different alleles), the round allele will mask the phenotypic expression of the wrinkled allele, expressing itself over it.

Level 5 - Organisms.
There are many factors that can affect pH in water, it can be natural or man-made. Water samples preserved in the jar for a long time then suddenly be exposed to outside environment will exhibit steadily decline in ph. The general explanation is because the water interacted with carbon dioxide molecules. This creates H2CO3 lowering the pH value but the reaction is usually minimal as H2CO3 has a low solubility constant (Henry’s Law).
