The surface area of the cell is 96μm², the volume of the cell is 64 μm³ and the surface area-to-volume ratio is 1.5 μm⁻¹.
What is surface area and volume?
The surface area of the cell is the area which is occupied by the surface of the object. The surface area of the cell with six sides of equal measurement = 4 μm.
Surface area of the cell can be calculated by the formula:
Surface area = length × width × number of sides
Surface area = 4 μm × 4 μm × 6
Surface area = 16 μm² × 6
Surface area = 96 μm²
The volume of the cell is the capacity of the cell. It is how much space is present inside the cell.
The volume of the cell with side 4 μm can be calculated by the formula:
Volume = length × width × height
Volume = 4 μm × 4 μm × 4 μm
Volume = 64 μm³
The surface area-to-volume ratio is the surface area divided by the volume of the cell. This indicates how much surface area is available compared to how big or the capacity of the cell is.
The Surface area: Volume ratio can be calculated as:
Ratio = 96 μm²: 64 μm³
Surface area-to-volume ratio = 1.5 μm⁻¹

5) Meerkats live together in groups called "Mobs." What kind of adaptation is this?
Meerkats inhabit huge underground tunnels in groups of 20–50 members of their extended family in groups called "mobs".
The female is the more powerful member of the alpha pair that controls these mobs. The majority of the group members are either the alpha pair's offspring or siblings.Meerkats are better able to survive when they live in communities. Adults alternately serve as the sentry or lookout during the day so that others can forage unafraid. A tall rock, termite mound, or shrub is scaled by the sentry, who then stands upright on two legs. He or she will use a specific call to signal the start of their guard duty. The sentry will bark or whistle an alarm if they notice a predator. The meerkats will flee to the closest hole, known as a bolt hole, if the sentry sounds the alert in anticipation of a predator. A meerkat mob may also stand together to appear larger and act fierce to frighten away the predator. They may even stir up dust to create concealment.Hence, it is an adaptation to survive.

-Peripheral Nervous System
The somatic nervous system is also a part of the peripheral nervous system. One of its roles is to relay information from the eyes, ears, skin and muscle to the central nervous system (brain and spinal cord).The motor neurons release a chemical, which is picked up by the muscle fibre. This tells the muscle fibre to contract, which makes the muscles move. Neurons carry messages from the brain via the spinal cord. These messages are carried to the muscles which tell the muscle fibre to contract, which makes the muscles move.
What is the function of our central nervous system?The Central Nervous System is made up of the brain and spinal cord. We can say that it is located inside the axial skeleton, even though some nerves penetrate the skull or the vertebral column.
With this information, we can conclude that The central nervous system (CNS) is made up of several types of cells and tissues: Neurons are the most important cells in the brain. They are responsible for receiving and transmitting stimuli from the internal and external environment, enabling the body to perform appropriate actions and responses.

What earths system are involved in the tomato plant hornworm relationship
The association between a tomato plant and a hornworm is known as parasitism.
Define parasitism.The hornworm caterpillar and tomato plant have a parasitic relationship because parasitism is a type of symbiotic relationship in which one organism benefits from the other while the other suffers. We are aware that hornworm caterpillars consume tomato crops by feeding on leaves. Therefore, the tomato plant is damaged while receiving nutrients from it. The tomato plant's edible vegetative portion serves as the system's input, and the hornworm caterpillar's transformation into a moth serves as the system's output.
All cowbird species and most cuckoo species engage in brood parasitism, a separate type of parasitism. Instead of making their own nests, these birds lay their eggs in those of other species and leave them there in the hopes that the adult birds of those other species will raise the abandoned young as their own.

How does scientists use information to make predictions in your own words and in a generalized manner?
Scientists create a broad principle or explanation to help anticipate future events using their understanding of past occurrences. The term "hypothesis" refers to the overall idea. Inductive reasoning is the category of reasoning that is involved (deriving a generalization from specific details).
How do scientist make predictions?A scientific prediction suggests the evidence that is in line with the hypothesis and can thus be used to the results of both current and previous experiments. As a result, even though these trials were carried out more than 200 years ago, we can make predictions about how they will turn out.
For the scientist, predictions serve as a point of reference. If predictions come true, the theory has been validated by the scientist. The hypothesis is disproved if the predictions are not confirmed. In either case, the scientist now has more understanding of the process being investigated.
