Answer;
When elements form a compound, the bonds and structure of the elements change.
Explanation;
-Elements are substances (such as oxygen and hydrogen) that can't be split into simpler substances using chemical means. They contain only one kind of an atom. A compound on the other hand is a substance that is formed when two or more elements are chemically joined.
-A compound's properties may differ greatly from those of its component elements. For example; at room temperature both oxygen (O2) and hydrogen (H2) are gases, while water (H2O) is liquid. This means that when elements form a compound, the bonds and structure of the elements change. The atoms in a compound are joined chemically using chemical bonds, such as covalent bonds, ionic bond and hydrogen bonds among others.
The study of genes and inheritance is called genetics. There are two types of alleles and these are recessive and dominant.
The correct answer is 75%.
Tall stems are dominant over short stems. Let T represent tall and t represent short. The parents are Heterozygous tall plants, which means that their genotype would be Tt and their phenotype would be tall. In a Punnett square it would look like this:
T t
T TT Tt
t Tt tt
Notice that we have 3 possible genotype combinations. When the dominant allele T is present that means that the phenotype that will be expressed is the dominant trait. In this case, we have the following genotype and phenotype:
TT Tall 1/4
Tt Tall 2/4
tt Short 1/4
The question is asking the chance the offspring phenotype is the same as the parent specifically so we can see that 3/4 are tall.
Hence, the correct is 3/4 = 75%.

One activity that can increase genetic variation within a population of earthworms is mutation.
Mutation is a process that results in a change in the DNA sequence of an organism's genome. Mutations can occur naturally due to errors in DNA replication, exposure to environmental factors such as radiation or chemicals, or as a result of genetic recombination during sexual reproduction.
Mutations can be beneficial, harmful, or neutral in their effects on an organism. They can introduce new variations or traits that can be subject to natural selection and influence the evolution of a population. Mutations can also cause genetic disorders or contribute to the development of cancer. The study of mutations and their effects is an important field in genetics and evolutionary biology.
