Answer:

to the first part: photosynthesis

i'm not sure about the second half, sorry

Explanation:

Answer:

The process used by plants to create their own food is called Photosynthesis. The reactants are sunlight mixing with water and carbon dioxide to create the product, Glucose and Oxygen.

Explanation:

During photosynthesis, light energy (sunlight) combines with the reactants—water and carbon dioxide—to form new products: glucose (sugar) and oxygen.

The part of the Peripheral Nervous System (PNS) that carries information to the Central Nervous System (CNS) is known as the Sensory or Afferent division.

The peripheral nervous system (PNS), together with the central nervous system (CNS), is one of two parts that make up an animal's nervous system (CNS). Outside of the brain and spinal cord, the PNS is made up of nerves and ganglia. The primary job of the PNS is to convey information between the brain and spinal cord and the rest of the body via connecting the CNS to the limbs and organs. The PNS, unlike the CNS, is not shielded from toxins by the blood-brain barrier, the spinal column, or the skull, unlike the CNS.

The sensory (afferent) division transports sensory impulses from central nervous system receptors via afferent nerve fibres (CNS). It can be separated into somatic and visceral divisions for further subdivision. Signals coming from receptors in the skin, muscles, bones, and joints are carried by the somatic sensory division. This division is responsible for transmitting sensory information from the body's receptors (such as those in the skin, muscles, and joints) to the CNS for processing and interpretation. The Sensory division is made up of sensory neurons, which are specialized nerve cells that are capable of detecting changes in the external or internal environment and converting these changes into electrical signals that can be transmitted to the CNS.

The refractory period following an action potential is significant because it ensures that the action potential moves in one direction down the axon and prevents the action potential from repeating in the same area.

The absolute refractory period is the time period during which a second action potential cannot be initiated, no matter how strong the stimulus is. This is because the voltage-gated sodium channels are inactive during this time and cannot be opened to allow the influx of sodium ions needed for an action potential.

The relative refractory period is the time period during which a second action potential can be initiated, but it requires a stronger stimulus than normal. This is because the voltage-gated potassium channels are still open, causing the membrane to be more negative than normal, and a stronger stimulus is needed to overcome this and reach the threshold for an action potential.

Overall, the refractory period plays an important role in ensuring the proper functioning of the nervous system and the transmission of information.

The gas exchange system in a bony fish is responsible for extracting oxygen from the water and releasing carbon dioxide.

This process occurs through the gills, which are specialized organs that are made up of filaments and lamellae. The filaments increase the surface area of the gills, allowing for more efficient gas exchange, while the lamellae contain blood vessels that help transport oxygen and carbon dioxide between the gills and the rest of the body.

When water warms, it loses its free oxygen, which can affect the gas exchange system of a bony fish. This is because the fish relies on the oxygen in the water to breathe, and if there is less oxygen available, the fish may have difficulty extracting enough oxygen to meet its metabolic needs. This can lead to a decrease in the fish's energy levels and may affect its ability to perform essential functions, such as swimming, feeding, and reproducing. In extreme cases, a lack of oxygen in the water can lead to the death of the fish.

Human systems are made up of many organs and tissues that work together to sustain the interior environment of the body. The process through which the body maintains a steady internal environment despite changes in the external environment is referred to as homeostasis.

The neurological system, endocrine system, respiratory system, cardiovascular system, digestive system, urinary system, and immunological system are all involved in homeostasis. These systems collaborate to control a variety of physiological processes including as temperature, blood sugar levels, pH levels, and electrolyte balance.

When the body is subjected to cold conditions, for example, the neurological system sends signals to the muscles to shiver, generating heat and raising body temperature. The cardiovascular system also responds by tightening blood vessels, which aids in the retention of heat in the centre of the body.

Similarly, when blood sugar levels rise after a meal, the endocrine system secretes insulin to help cells absorb glucose for energy generation. When blood sugar levels go too low, the endocrine system produces glucagon, which causes the liver to release glucose.
