In modern systematics, species are organized into monophyletic groups based on their evolutionary relationships; that is, they are organized into clades.
Systematics is a branch of biology that deals with classification of organisms based on their species, genus or taxa, which represents their evolutionary relationships. A monophyletic group consists of members having common ancestral origin and all the descendants of that most recent common ancestor. It is same as cladistic grouping. It also has descendants of common ancestors. Identification of evolutionary relationships helps in understanding the anatomy of the extinct organisms, their development over time and how their features evolved to survive in the changing nature/ environmental conditions. Evolutionary biology seeks to explain the diversity of life and interpret the adaptations among the species. With time, the most fit species survived by the process of natural selection of best evolved species.

Explanation:
A tree species has one facultative mutualist animal that disperses its seeds. If the animal goes extinct, what is the most likely consequence for the tree species?
A tree species has one facultative mutualist animal that disperses its seeds. If the animal goes extinct, the most likely consequence for the tree species is mean seedling distance from parent tree.
What do you understand by the term extinct?Extinction is the final phase of a sort of creature or a taxon—typically a species. Although the ability to reproduce and bounce back may have been lost earlier, the death of the last member of the species is typically considered to be the moment of extinction.
What do you mean by seedling?A seedling is a juvenile sporophyte that has emerged from a plant embryo. The germination of the seed initiates the growth of the seedling. The radicle (embryonic root), hypocotyl (embryonic shoot), and cotyledons make up the majority of immature seedlings (seed leaves). The number of seed leaves that make up the two groups of flowering plants (angiosperms) differs: monocotyledons (monocots) have one blade-shaped cotyledon, whereas dicotyledons (dicots) have two round cotyledons. Gymnosperms have a wider range. Some blooming plant seedlings lack any cotyledons at all. They are described as acotyledons.
Thus from above conclusion we can say that a tree species has one facultative mutualist animal that disperses its seeds. If the animal goes extinct, the most likely consequence for the tree species is mean seedling distance from parent tree.

Deoxyribonucleic acid is a kind of DNA. DNA is a polymer made up of two polynucleotide chains that coil around one another to create a double helix. (listen);[1] DNA) All known organisms and many viruses have genetic information in the polymer that is necessary for their development, operation, growth, and reproduction. Nucleic acids include DNA and ribonucleic acid (RNA). Nucleic acids are one of the four main categories of macromolecules that are necessary for all known forms of life, along with proteins, lipids, and complex carbohydrates (polysaccharides).

During the cell cycle, cyclins activate CDK, and together they form complexes that stimulate the cycle progession. The provided statement is false because this complex does not inhibit (stop) the cell cycle by itself.
What is the role of cyclin/CDKs complexes?Cyclins are cell cycle regulator proteins that control the cell during the process of division. Different types of cyclins act on a different stages.
For each stage of the cell cycle, there is an especific cyclin,
When the cell is going through one of the stages, the only cyclin in high levels is the one that is regulating that part of the cycle.Once that stage is over, that cyclin concentration decreases, and the following one increases.Kinases, Cdk, are enzymes that depend on cyclins and that remain inactive until cyclins are present.
The enzyme becomes functional when the cyclin binds it. Then, the kinase can accomplish its functions.
When the cyclin and the kinase are together, they compose the Maturation Promotor Factor, MPF.
MPF is composed of cyclin and kinase. MPF controls the cell cycle evolution, and is in charge of letting the cell go from the G2 stage to the M stage.
The inactivation of MPF is regulated by cyclin-dependent kinase inhibitors (CKIs) that are proteins that regulate cyclins and kinases bonds due to the degradation of cyclin. As cyclin is destroyed, the MPF gets inactive.
