Answer:
Answer is option A.
Vestigial features are fully developed and functional in one group of organisms but reduced and function less in a similar group.
Explanation:
- Vestigial structures are anatomical features such as cells, tissues or organs in an organism that are previously functional and performed some important functions in the organism but no longer serve any functions in the current form of the organism and become useless as a result of a large evolutionary change. Examples include the coccyx or the tailbone in humans, the pelvic bone of a snake, wisdom teeth in humans, nipples in human males, the wings of flightless birds such as kiwi, ostrich, etc.
- Homologous features are the features that are similar in different organisms having similar embryonic origin and development and are inherited from a common ancestor that also had that feature. Also, they might have different functions. An example is the presence of four limbs in tetrapods such as crocodiles, birds, etc.
- Analogous features are the features that are superficially similar in different organisms but had separate evolutionary origins i.e., different in origin, but similar in function. An example includes the wings on a fly, a moth, and a bird where the wings were developed independently as adaptations to perform the common function of flying.
- Polygenic features are the traits or features that are controlled by multiple genes that are located on the same or different chromosomes and are also affected by the environment. These features do not follow Mendel’s pattern of inheritance and are represented as a range of continuous variation. Examples of polygenic traits or features include skin color, height, hair color, eye color, etc. For example, there is wide variation in the human skin color (from light to dark) and height (short or tall or somewhere in between).
- Sympatry describes a species or a population that inhabit the same geographic region at the same time. In sympatric speciation, new species are evolved from a surviving ancestral species while both the species inhabit the same place at the same time i.e., in a single population, reproductive isolation occurs without geographic isolation.
Just take out the fluff.
Plants that are fertilized with fish meal will be healthier for plants than the plants that receive artificial fertilizer.
Or make one of those If, Then, Because statements.
If a plant is fertilized with fish meal rather than artificial fertilizer, then the plants will be overall healthier because fish meal is natural compared to the artificial fertilizer.
Temporary storage sites in the cytosol for substances such as pigments or nutrients are called inclusions.
Pigments are the compounds that have a certain color and provide color to other structures indie the body. For example in plants chlorophyll is the pigment that provides green color to the leaves and stem. In humans and other animals, the blood consists f red colored pigment called hemoglobin.
Inclusions are the non-living objects inside the cell. They can be anything like pigments or any other molecules, that performs no function inside the cell. They are also called ergastic substances and do not even have any membrane.

A.
conserve energy
The smaller muscle mass of the sloth, means that it needs less energy to work, allowing it to be able to survive on a less diet.
Most of their muscles are concentrated in their upper body, allowing them to be efficient climbers but very slow on the ground.
