They both contain carbon but nucleic acids contain phosphorus. So, the correct option is D.
What are nucleic acids and carbohydrates?
Nucleic acid is a naturally occurring chemical compound that is capable of being broken down to yield phosphoric acid, sugars, and a mixture of organic bases (purines and pyrimidines).
Nucleic acids are the main information-carrying molecules of the cell, and, by directing the process of protein synthesis, they determine the inherited characteristics of every living thing. The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Carbohydrate is any member of a large and diverse family of naturally occurring organic molecules that include sugars, starch, and cellulose.
Monosaccharides (simple sugars such as glucose and fructose), disaccharides (2-unit sugars such as sucrose and lactose), oligosaccharides (3-10 or more sugars), and polysaccharides are the most prevalent types (large molecules with up to 10,000 monosaccharide units, including cellulose, starch, and glycogen).
Therefore the correct option is D.

A mutation that causes resistance in a population of beetles is an example of _______. a. macroevolution b. microevolution c. migration d. reproduction please select the best answer from the choices provided a b c d
A mutation that causes resistance in a population of beetles is an example of microevolution and the reason is mutation.
Evolution means when something evolves or changes and gets adopted because of those changes eliminating the previous population and getting fit in the environment and then leading life and growing and increasing their population. Evolution can be both macros which means evolution which is bigger and got sustained for a longer time and microevolution which means evolved but was not able to be sustained for a longer duration and is the change in allele frequencies that occurs over time within a population. This change is due to four different processes: mutation, selection, gene flow, and genetic drift. This change happens over a relatively short amount of time and in the case of the beetle's population, it is an example of microevolution because mutations are changes in genetic level so beetles were able to survive but not for a longer time and the changes didn't leave it effect for longer periods of time and few pieces of evidence of it are pesticide resistance, herbicide resistance, and antibiotic resistance are all examples of microevolution by natural selection.To know more about microevolution this click at https://brainly.com/question/8318826

What type of signal directs the synaptic vesicles to release their neurotransmitters into the synapse?.
Electrical signals direct the synaptic vesicles to release their neurotransmitters into the synapse.
Synaptic vesicles are the key organelles at the neuron terminals involved in synaptic transmission. They store neurotransmitters that are released in the synapses through an electrical impulse. A synapse is a gap between two neurons through which the electrical impulse is transferred from one neuron to another.
Directing synaptic vesicles through electrical impulses occurs by exocytosis. Exocytosis is observed to be a result of protein-protein interactions. Proteins of synaptic vesicles interact with the proteins of the plasma membrane of the pre-synaptic axon terminal and direct the synaptic vesicle to release neurotransmitters into the synapse.
We can thus say that neurons communicate through electrical impulses, often called action potentials, and chemical neurotransmitters released into the synapse.

The tissue found covering body surfaces, lining body cavities, forming the internal and external linings of many organs, and constituting most gland tissue is tissue.
The tissue found covering body surfaces, lining body cavities, forming the internal and external linings of many organs and constituting most gland tissue is epithelium tissue.
Epithelial tissues are one of the four basic types of animal tissues, the rest being muscular tissues, connective tissues and nervous tissues. They are thin, continuous, packed, protective layers of cells that line the outer surfaces of blood vessels and organs. Epithelial tissues can be classified based on the shape of individual cells and based on the number of layers.
Based on shape, epithelial tissues can be divided into squamous, cuboidal and columnar epithelial cells. Squamous cells are usually flat and are found on surfaces that are susceptible to rubbing and abrasion as they are easily replaced, for example, the skin. Cuboidal epithelial cells are cube shaped, and columnar cells are long. Some columnar epithelia have hair-like projections called cilia, and some act as glands and secrete mucus.
Based on the number of layers of cells, epithelial tissues can be divided into simple (single layer) and stratified (multiple layer) epithelial cells.

What is a trophic web?
The trophic web is the interaction between different organisms involving the transference of energy when some of them feed on the other ones.
Organisms occupy different trophic levels in the web. The ones placed at lower levels pass energy to the ones at the higher levels.
Organisms at each level feed on the preceding one and become food for the next one.
The first link corresponds to a producer organism -autotroph-.The following links are the consumers -heterotrophs-: herbivores and carnivores.The last links are the decomposers that degrade organic matter from dead organisms.A trophic web is composed of different food chains. Several food chains interconnected create a trophic web (food web).
Because it is a web, all organisms are in equilibrium until a change occurs. When a sudden change affects any of the involved links, there can be a cascade effect on the web.

Which process occurs during a light-independent reaction?
A light source stimulates electrons to move through a chain of proteins called the electron transport chain.
The reaction uses the energy from ATP and NADPH molecules to form glucose from carbon dioxide.
Green chlorophyll molecules absorb solar energy.
ATP and NATPH molecules become energy carriers for the next stage of reactions.
The Calvin-Benson cycle and the light independent process both take place in the stroma of the chloroplast. Carbohydrates are created from carbon dioxide through a sequence of chemical processes.
These processes are powered by the ATP and NADPH produced during the light-dependent process.
What is referred to as photolysis?Photolysis is the interaction of one or more photons with one target molecule and is a chemical reaction in which an inorganic chemical (or an organic chemical) is broken down by photons. It is also referred to as photodissociation and photodecomposition.
ADP and a phosphate group are joined by the rotating ATP synthase to create ATP. This procedure, known as chemiosmosis, enables light-dependent electron transport to generate ATP in addition to NADPH (which is produced at the ETC's conclusion).
The Calvin cycle is also known as the C3 cycle, the nighttime reaction of photosynthesis, or the light-independent reaction. However, it is most active during the daytime when there is a surplus of ATP and NADPH.
