The taxon or set of taxa are not present in viridiplantae is Nori taxa and is not present in viridiplantae.
Approximately 450,000–500,000 species of eukaryotic organisms belong to the group Viridiplantae, which is crucial to both terrestrial and aquatic environments. Chlorophyta and Streptophyta are the two divisions or phyla that usually make up the group of green plants, or Viridiplantae; the latter group includes the land plants known as embryophytes as well as a type of green algae known as streptophyte algae.
A taxon is a collection of one or more populations of an organism or populations that taxonomists consider to be part of the same entity. A taxon typically has a name and a grade assigned to it, even though neither is necessary, especially if and when it is accepted or establish.

Hydrogen bonding noncovalent interaction supports the double helix of DNA and produces the base pairings A-T and G-C.
The two different types of nucleic acids are as follows:
Deoxyribonucleic acid (DNA)
Ribonucleic acid (RNA)
Both RNA and DNA molecules couple their bases. Adenine, uracil, guanine, and cytosine are the bases found in RNA molecules while guanine, adenine, cytosine, and thymine are found in DNA molecules.
A is always linked with T in a DNA molecule, while G is always coupled with C, and base T is changed to base U in RNA. There is a weak hydrogen connection that can be easily broken between a base pair and the double helix of the DNA molecule.

The things a growing plant has in biosphere, lithosphere, atmosphere and hydrosphere has are as follows:
WaterSoilAirThe plant itselfHow water, soil, air and plant are parts of the the hydrosphere, lithosphere, atmosphere and the biosphere.Water is the liquid portion of the earth and it found in the plants part. The liquid part of the earth is known as the hydrosphere. However, water is one of the conditions necessary for photosynthesis to take place.
The lithosphere is the solid portion of the earth and one of the parts of the lithosphere simply is the soil. Plants need good soil proper growth and development.The air is a mixture of gases and it is found in the atmosphere. This air contains carbon dioxide which is also some of the raw material necessary for photosynthesis to occur.The biosphere is the living portion of the earth. The plant as a whole itself is a living thing and is found in the biosphere.In conclusion, it can be deduced from the explanation given above that plants can manufacture food substances by themselves with help of good soil, water and carbon dioxide.

the sequence of the coding strand of a dna molecule (that is, the dna strand that contains the codons specifying the protein sequence) is 5'-cggatgctta-3'. what is the sequence of the rna made from this dna?
Transcription of an RNA strand with the sequence "AUUGCGCGAA" from a DNA strand with the sequence "TAACGCCTT" As a result, C is the correct answer.
Transcription is the process by which mRNA is created from DNA in the nucleus of a cell. The nucleus contains all of the enzymes and nucleotides required for the production of mRNA. The messenger RNA (mRNA) is transcribed from DNA The mRNA sequence generated in a cell from DNA is complementary to the leading strand of DNA, with only the thymine residues replaced by uracil residues. Adenine base couples with uracil residues, and thymine base pairs with adenine residues. Cytosine bases couple with guanine bases and vice versa.

Due to ______, equatorial regions of earth have warm temperatures year-round, and nonequatorial regions experience lower temperatures, less light, and seasonal changes.
The earth's equatorial and nonequatorial areas both experience warm temperatures all year round as a result of global warming.
What is the primary reason for seasonal fluctuations in temperature?The spin axis of the earth is inclined to its orbital plane. This triggers the change of the seasons. It is summer where the axis of the earth faces the sun. When the axis of the globe is facing away, winter is to be expected.

in the past decade, there have been many volcanic eruptions. after an eruption, the lava flow leaves behind only bare rock, providing a surface for primary succession. which statement describes an important function provided by the first organisms to colonize the area that facilitates colonization by other organisms in later stages of succession?
After an earthquake or volcanic eruption, lichens break down the rocks to produce new, nutrient-rich soils. This process is known as primary succession.
Lichens and mosses that have colonized the region help weather the rock, which breaks it down and creates soil for other species to occupy. When new land is formed or exposed rock occurs, such as during a volcanic eruption like those on Hawaii's Big Island. This process is known as primary succession. As the volcanic lava pours into the water, new land is continually created. These species aid in further decomposing the mineral-rich volcanic lava into soil, allowing for the ultimate replacement of the pioneer species by less resilient species. Additionally, when these early species develop and pass away, they add to a layer of organic matter that is already decaying, aiding in the development of soil. The region will eventually achieve a state of equilibrium with a collection of creatures that are very different from the pioneer species. The development of soil is also influenced by lichens, mosses, and other plants. Physical weathering is the term used to describe the method by which the aforementioned species weather rocks.

Most of the electrons removed from glucose by cellular respiration are used for which of the following processes?
The majority of the electrons extracted from glucose by cellular respiration are used in these processes: "reducing NAD+ to NADH in glycolysis and the citric acid cycle" and "producing a proton gradient for ATP synthesis in the mitochondria". Hence, the correct answer is E.
Electrons from glucose move progressively down the electron transport chain towards oxygen in cellular respiration, going through lower and lower energy levels and releases of energy at every step. Cellular respiration's purpose is to harness that energy into a form of adenosine triphosphate, or ATP.
The citric acid cycle is a sequence of chemical processes that remove high-energy electrons and then utilize them to make ATP in the chain of electron transport. Each cycle generates one adenosine triphosphate molecule or its equivalent.
The mitochondria create the majority of the adenosine triphosphate formed during glucose metabolism via oxidative phosphorylation. This is a complicated mechanism driven by the proton gradient formed by mitochondrial respiration across the inner membrane of the mitochondria.
This question should be provided with answer choices, which are:
A. Reducing NAD+ to NADH in glycolysis and the citric acid cycle.B. Producing a proton gradient for ATP synthesis in the mitochondria.C. Driving substrate-level phosphorylation in glycolysis.D.

With age, the spine stiffens as a result of shrinkage of the intervertebral disc spaces, and the vertebrae become brittle. This increases the risk of Compression fractures.
What is compression fracture?
When one or more vertebrae are under too much stress, they might collapse and result in a spine compression fracture. Serious spinal compression fractures might impair your quality of life with painful or incapacitating symptoms.
With rest, the use of a brace, and painkillers, the majority of compression fractures resulting from injuries heal in 8 to 10 weeks. However, if surgery was performed, recuperation might take significantly longer.
Therefore, age causes the intervertebral disc gaps to contract, which stiffens the spine and makes the vertebrae more fragile. Compression fractures are now more likely as a result of this.

The Punnett square is a rectangular shape diagram used to predict genotypes of a specific cross or breeding experiment. It is named after Reginald C. Punnett, who invented it in 1905. Biologists use the diagram to calculate the likelihood of an offspring having a specific genotype. Again, this is determined by the alleles present in a plant at a single genetic locus. The allele for wrinkled seeds (W) is dominant over the allele for round seeds in this case (w).
