Answer:
The particles inside the nucleus of an atom are a proton and neutron. These two subatomic particles are determine the atomic mass of an atom. The proton identifies an atom and changes the characteristics of atoms. A proton is a positive charge and a neutron is a neutral charge
Explanation:
B. detailed descriptions and informal language
C. rhyme, rhythm, and repetition of certain words
D.elevated language and lists of historical events
Answer;
-Rhyme, rhythm, and repetition of certain words
The elements that are best known for helping performers memorize an epic poem include rhyme, rhythm, and repetition of certain words.
Explanation;
-Rhyme is the repetition of the final sound or sounds of a word. It is used to create unity of sound and sense, and repetition to assist memory. Rhythm is important in making it easier to remember for recitation. These rhythms are especially enjoyable, because they reflect the natural movement of the human body
Natural selection has been the process that allows organisms to adapt to changes. Heritable variations for some traits are required for natural selection. Thus, option A is correct.
Natural selection has been defined as the process of survival and reproduction that are evident in evolution and are characteristic of a population or generation of the species.
For natural selection to occur variations, existence and inheritance are the major requirements that are crucial for the organism to show the adaptation and evolutionary process.
Traits inherited from the previous generation must show some variation so as to make the current generation more beneficial and selectable over the ancestral generation.
Therefore, option A. the heritable variations of some traits are an important factor for natural selection.

Your question is incomplete, but most probably your options were,
Answer:
1. heritable variations for some traits
Explanation:
Assuming the options are:
there are four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population. If they are met, natural selection automatically results.
B) DNA replicates before the division.
C) the daughter cells are diploid.
D) homologous chromosomes synapse.
E) the chromosome number is reduced.
Meiosis II is similar to mitosis in that A- sister chromatids separate during anaphase, whereas homologous chromosomes separate during meiosis I. Unlike meiosis I, meiosis II does not involve DNA replication before the division.
Meiosis II is similar to mitosis in that sister chromatids separate during anaphase. During anaphase II of meiosis, the sister chromatids, which are identical copies of each other, move to opposite poles of the cell, just like in mitosis. This separation ensures that each daughter cell receives a complete set of chromosomes.
This statement is in contrast to meiosis I, where homologous chromosomes separate during anaphase. Homologous chromosomes are pairs of chromosomes, one from each parent, and separating them during meiosis I results in genetic variation.
Additionally, meiosis II, similar to mitosis, does not involve DNA replication before the division. DNA replication occurs in meiosis I, but during meiosis II, the sister chromatids that were formed in meiosis I remain intact and separate without any further DNA replication.

Answer:
The central dogma of biology explains the flow of inherited information that takes place in our cells. It states that information flow from existing DNA to make new DNA by the process of replication, and after that that replicated DNA is used to make a new RNA by the transcription process further from that RNA new protein is synthesized by translation process.
All these information flow from DNA to RNA and then from RNA to protein is called as central dogma in biology.
