Can you explain ionization energy? What are the periodic table trends for ionization energy?
Ionization energy is the energy needed to remove an electron. As one moves across the period from left to right, the ionization energy increases, meaning it becomes harder to extract an electron. As one moves down the column, the ionization energy decreases and it becomes easier to remove an electron.
What are the phases of the animal cell cycle? What are the stages of Mitosis and what exactly does Mitosis accomplish?
The cell cycle in animals can be divided into two major phases: Interphase (the longest phase) and M-phase (or Mitosis). During interphase, the cell goes through G1 phase, during which it is actively growing and metabolizing. Following G1, S-phase occurs. The S indicates "synthesis" is called the synthesis phase because during this time, the cell is duplicating its DNA (DNA synthesis is occurring). Following S-phase is G2 phase. Again, the cell is actively growing and metabolizing in preparation for Mitosis. The phases of Mitosis are as follows: Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis. The goal of Mitosis is for a cell to duplicate itself by doubling its genetic material (DNA) and forming two identical daughter cells.
What is the difference between an adjective and an adverb? Also, what exactly is a pronoun?
I will begin by addressing your second question, as it will help you understand the answer to the first. A pronoun is a substitute for a noun or a noun phrase. There are various types of pronouns, but you should definitely be familiar personal pronouns. For example, "he", "she", "they", "me", etc. are all pronouns, as they replace or substitute a noun. Back to your first question: adjectives modify nouns, noun phrases, and pronouns. They make nouns, noun phrases, and pronouns more precise: in other words, they further describe whatever they're modifying. For example, the adjective in the following sentence is "big": "The big dog ran away." The word "big" describes the dog (which is a noun). An adverb, on the other hand, modifies a verb, an adjective, or another adverb. Adverbs can be easily identified because they usually end in -ly. The following three examples will show how an adverb can modify either a verb, adjective, or another adverb. Example 1: The dog ran slowly. "Slowly" is the adverb in that sentence as it modifies the verb "ran". It tells you something about the action. Example 2: The dog was extremely big. In this sentence "extremely" is the adverb and it modifies the adjective "big". Example 3: The dog ran very quickly. "Very" is the adverb here and it modifies another adverb, "quickly".
