DNA and complementary base pairing
The deoxyribonucleic acid (DNA) is a double helix composed of two long chains of sequential nucleotides.
In DNA there are four classes of nucleotides, each containing one different nitrogenous base (i.e., Adenine, Guanine, Cytosine, Thymine).
According to the base pair rules of complementarity, Adenine always pairs with Thymine, whereas Guanine always pairs with Cytosine.
In conclusion, the order of the bases on the opposite strand of DNA should be Thymine, Guanine, Guanine and Cytosine.

Which part of the cell theory best explains why unicellular organisms can perform all life’s basic functions even though they are made up of one cell
Answers
Answer: The part of the cell theory that best explains why unicellular organisms can perform all life's basic functions is "all living things are composed of cells."
Explanation: This means that unicellular organisms are composed of a single cell that has all the necessary components and functions to carry out life processes on its own. The cell is the basic unit of life and contains all the necessary structures, such as a cell membrane, cytoplasm, and genetic material, that allow it to carry out functions such as reproduction, metabolism, and response to stimuli. Therefore, unicellular organisms can perform all basic life functions because their single cell contains all the necessary components to do so.

what type of reaction releases energy when bond is broken
Answers
Exothermic
Explanation:Chemical reactions that release energy are called exothermic. In exothermic reactions, more energy is released when the bonds are formed in the products that are used to break the bonds in the reactants. Exothermic reactions are accompanied by an increase in the temperature of the reaction mixture. Energy is absorbed to break bonds. Bond-breaking is an endothermic process. Energy is released when new bonds form.
Answer:
Exothermic reaction
Explanation:
We have two types of chemical reactions, exothermic and endothermic reactions. Endothermic reactions refers to the one in which the reactants absorb the heat energy from the surroundings to form products.
An exothermic reaction refers to the one in which there is energy release in the form of heat and light.
Hence our required reaction is exothermic reaction.

Answers
Answer:
The Cell Cycle | Back to Top
Despite differences between prokaryotes and eukaryotes, there are several common features in their cell division processes. Replication of the DNA must occur. Segregation of the "original" and its "replica" follow. Cytokinesis ends the cell division process. Whether the cell was eukaryotic or prokaryotic, these basic events must occur.
Cytokinesis is the process where one cell splits off from its sister cell. It usually occurs after cell division. The Cell Cycle is the sequence of growth, DNA replication, growth and cell division that all cells go through. Beginning after cytokinesis, the daughter cells are quite small and low on ATP. They acquire ATP and increase in size during the G1 phase of Interphase. Most cells are observed in Interphase, the longest part of the cell cycle. After acquiring sufficient size and ATP, the cells then undergo DNA Synthesis (replication of the original DNA molecules, making identical copies, one "new molecule" eventually destined for each new cell) which occurs during the S phase. Since the formation of new DNA is an energy draining process, the cell undergoes a second growth and energy acquisition stage, the G2 phase. The energy acquired during G2 is used in cell division (in this case mitosis).

Explanation:
Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, and peroxisomes. Both also contain similar membranes, cytosol, and cytoskeletal elements.
Both animal and plant cells have mitochondria, but only plant cells have chloroplasts.
Animal cells have centrioles, centrosomes (discussed under the cytoskeleton), and lysosomes, whereas plant cells do not. Plant cells have a cell wall, chloroplasts, plasmodesmata, and plastids used for storage, and a large central vacuole, whereas animal cells do not.
