The correct answer is: b) There are a diverse array of flower shapes and colors, largely related to the mode of pollination.
Angiosperms or flowering plants are plants with characteristic feature called flower. The main function of this plant structure is to ensure fertilization and development of fruit containing seeds. Flowers need to attract pollinators by their color, scent, and nectar (secreted in some part of the flower).

Explanation:
B) Flagella
C) Microtubules
D) Ribosomes
Answer:
The correct answer would be D) Ribosomes.
Ribosomes serve as the site of translation in prokaryotes as well as eukaryotes.
It produce proteins or polypeptide chains with the help of mRNA (messenger ribonucleic acid) and tRNA (transfer ribonucleic acid).
It gets attached or assembled near the start codon of the mRNA. mRNA provides the instruction from the DNA (deoxyribonucleic acid) to the ribosome in the form of codon sequence.
The codon sequence are then decoded with the help of tRNA which then adds specific amino acid to the growing polypeptide chain.
As soon as the ribosome reaches stop codon, it releases the mRNA and polypeptide chain.
The peptide chain then undergoes various post-translation changes to become a mature and functional protein.
Freshwater ecosystems, constituting a mere 1.8 percent of Earth's surface, are characterized by their biodiversity and the crucial ecosystem services they offer, including provision of drinking water, sanitation, and industrial uses. They house different zones due to varying abiotic factors like temperature and light penetration, with each zone inhabited by species adapted to these conditions. They are intrinsic to the well-being of terrestrial biomes, linked through various abiotic and biotic factors.
Freshwater ecosystems are of immense importance due to their rarity, diversity, and functionality. They encompass only 1.8 percent of the Earth's surface, including lakes, rivers, streams, and springs. These ecosystems are incredibly biodiverse, supporting a wide variety of species such as fish, amphibians, reptiles, insects, phytoplankton, fungi, and bacteria.
Humans are heavily reliant on these freshwater biomes as they provide indispensable ecosystem services. They supply fresh drinking water, assist in crop irrigation, provide sanitation facilities, recreation spaces, and serve various industrial purposes. Conservation of these freshwater ecosystems is crucial for the preservation of terrestrial biomes, as they are interlinked through abiotic and biotic factors.
Temperature, light penetration, and water movements are key abiotic factors influencing these ecosystems. The structural compositions of aquatic systems are largely shaped by density and temperature. Such factors delineate different zones within these systems, each housing organisms adapted to specific conditions.

Answer:
Alcoholic fermentation
Explanation:
Some bacteria and yeasts get energy by fermenting sugars, this reaction has as its end product ethyl alcohol and carbon dioxide (CO2), this process is called alcoholic fermentation.
Alcoholic fermentation occurs as follows: in order to react, each glucose molecule initially consumes 2 ATP to be activated. When this occurs, the glucose molecule begins to undergo various reactions until it gives rise to two molecules of pyruvic acid.
In the course of these reactions, enough energy is released to recompose 4 ATP. Each pyruvic acid molecule then decarboxylates to ethyl alcohol or ethanol.
After all these processes, the energy balance of alcoholic fermentation is: 4 ATP produced minus 2 ATP consumed to activate glucose, resulting in abalance of 2 ATP.
Human beings use alcoholic fermentation products mainly for the production of alcoholic beverages, where ethyl alcohol acts, and bread, considering that the release of carbon dioxide causes the dough to grow.
The binomial nomenclature system used in biology for the scientific naming of organisms uses two Latin words to designate each individual species. The first word represents the genus, and the second word, the species.
Binomial nomenclature, which is used in biology for the scientific naming of organisms, uses two Latin words. These words are formed from Latin or Greek roots, regardless of the language spoken by the scientist.
The first word represents the genus, and the second word, the species. For example, the human species is scientifically named Homo sapiens, where 'Homo' is the genus, and 'sapiens' is the species.
