The messenger neurons that transmit information from various impulses bodily regions to the central nervous system are known as afferent nerves (CNS).
The axons that project from peripheral organs and deliver stimuli to the central nervous system are referred to as afferent nerves in biology. Impulses are delivered to the central nervous system (CNS) by the afferent or sensory division. In order to produce an effect or action, the CNS sends impulses through the efferent or motor division to the external organs.
The nerve cells known as afferent neurons, sometimes known as sensory neurons, are in charge of carrying sensory data from the outside environment into the brain. The sense of touch and temperature are examples of sensory information, along with other unique senses like vision, hearing, smell, or taste.

slender extensions of the plasma membrane that increase its surface area is called___
slender extensions of the plasma membrane that increase its surface area is called microvilli .
Cells that are involved in absorption or secretion, such as those lining the small intestine and kidney tubules, have microvilli on their surfaces. They expand the plasma membrane's surface area, enabling chemicals to be absorbed or secreted more effectively. Actin filaments make up microvilli, which are sustained by a protein network immediately below the plasma membrane. Compared to cilia and flagella, two other cellular extensions involved in movement and sensory processes, they are generally shorter. The apical surfaces of polarised epithelial cells include microvilli, which increase the surface area of the cell exposed to the lumen to improve absorption and secretion.
Thousands of densely packed microvilli protrude from each tiny intestinal epithelial cell into the gut lumen.

Cellular respiration project: analyzing cellular respiration. !! In this assignment, you will gather evidence to construct an explanation on how energy and matter move through the environment under aerobic and anaerobic conditions. You will then conduct additional guided research to revise your explanation based on the new information you discover. BACKGROUND INFORMATION Cellular respiration is a process that allows organisms to produce energy to maintain life. The process involves a series of chemical reactions that use glucose and oxygen to produce carbon dioxide, water, and the high energy molecule, ATP. Organisms, including plants, undergo cellular respiration to create energy that they can use to maintain life processes. Cellular respiration may be aerobic, a type of respiration that requires oxygen, or anaerobic, a type of respiration that can occur in an environment with no or minimal oxygen
Cellular respiration is a crucial process that allows organisms to produce energy to maintain life.
The process involves a series of chemical reactions that use glucose and oxygen to produce carbon dioxide, water, and the high-energy molecule, ATP. There are two types of cellular respiration: aerobic and anaerobic. Aerobic respiration requires oxygen, while anaerobic respiration can occur in an environment with no or minimal oxygen.
In aerobic respiration, glucose is broken down into carbon dioxide and water, with the release of energy in the form of ATP. This process occurs in the mitochondria of the cell and involves three main stages: glycolysis, the Krebs cycle, and the electron transport chain.
In anaerobic respiration, glucose is broken down into lactic acid or ethanol, with the release of a small amount of energy in the form of ATP. This process occurs in the cytoplasm of the cell and involves only one stage: glycolysis.
To analyze cellular respiration, you can gather evidence through experiments and observations. For example, you can measure the amount of oxygen consumed and carbon dioxide produced during aerobic respiration, or the amount of lactic acid or ethanol produced during anaerobic respiration. You can also conduct additional guided research to revise your explanation based on new information you discover.
In conclusion, cellular respiration is a vital process that allows organisms to produce energy to maintain life. It involves a series of chemical reactions that use glucose and oxygen to produce carbon dioxide, water, and ATP. There are two types of cellular respiration: aerobic and anaerobic, each with its own unique processes and products.

Which form of energy is Not correctly associated with an example? a) kinetic energy : fat molecules
b) kinetic energy : movement of muscles
c) chemical energy : glucose
d) potential energy : water held behind a dam
e) potential energy : ATP
Answer:
A) Kinetic energy: fat molecules is not correctly associated
Explanation:
A) Kinetic energy: fat molecules is not correctly associated
Fat molecules have chemical potential energy, which can be converted into kinetic energy when the body metabolizes them for fuel. Kinetic energy is associated with movement, so options B (movement of muscles) and E (ATP) are correctly associated. Chemical energy is stored in molecules such as glucose, so option C is correctly associated. Potential energy is associated with energy that is stored in an object or system, so options D (water held behind a dam) and E (ATP) are correctly associated.
Answer:
Option (a) is not correctly associated as fat molecules are a form of potential energy rather than kinetic energy. Fat molecules contain stored chemical energy that can be converted into kinetic energy during metabolism or other processes.
The correct association for option (a) would be "potential energy: fat molecules".

the swine flu virus can only infect pigs and humans. why can't it infect other species?
The swine flu virus is an influenza virus that is specific to the species of swine, which are animals such as pigs, hogs, and boars.
It is believed that the virus originally evolved from a combination of avian and human influenza viruses, and this is why it is able to infect both pigs and humans. However, the virus has not been found to be able to infect any other species. This is because the virus has only evolved to be able to attach to specific cell receptors that are found on the surface of pig and human cells. These cell receptors are part of the immune system and act as doorways to the cell, allowing the virus to enter and begin the infection process.
