Afferent as well as sensory neurons are the ones that transmit data to the spinal cord and brain from receptors on the body's periphery.
The spinal cord is where information processing starts after afferent neurons inside the dorsal roots convey impulses from of the body's sense receptors. Efferent motor neurons, that regulate the body's periphery, are found in the ventral horns. Efferent neurons transmit motor information out from the central nervous system to a muscles or glands of the body, whereas afferent neurons transport information from sensory receptors of a skin as well as other organs to a central nervous system. Efferent neurons, also referred to as motor neurons, transmit information from the central nervous system (CNS) to muscles as well as other peripheral systems like organs and glands.

dual innervation means that an individual effector
False, Dual innervation refers to the phenomenon where an organ or tissue is innervated by both sympathetic and parasympathetic nervous systems.
This is common in many organs in the body, including the heart, lungs, and digestive system. The sympathetic and Dual innervation parasympathetic nervous systems have opposing effects on these organs, with the sympathetic system generally promoting activity and the parasympathetic system promoting relaxation. The balance between these two systems is important for maintaining homeostasis in the body.

if an herbicide blocked the calvin cycle before the generation of g3p, what would happen? please refer to the following art to answer the following question. the figure shows the calvin cycle. an enzyme adds each co2 to a five-carbon sugar called rubp. that breaks molecule into two three-carbon molecules. using energy from the light reactions, enzymes convert each three-carbon molecule to the three-carbon sugar g3p. for every three molecules of co2 that enter the cycle, the net output is one g3p sugar. the other g3p sugars continue in the cycle. using energy from atp, enzymes rearrange the remaining g3p sugars to regenerate rubp. if an herbicide blocked the calvin cycle before the generation of g3p, what would happen? no oxygen would be released by the plant. only rubp would be recycled. the plant would still be able to make sugar, just a lot less. no sugar would be made by the plant.
If an herbicide blocked the Calvin cycle before the generation of G3P, Option D: no sugar would be made by the plant, is true.
In order to FIX carbon from CO2 into three-carbon sugars, plants go through a chain of chemical processes known as the Calvin cycle. In turn, amino acids, nucleotides, and more complex sugars like starches can be made from the three-carbon sugars. In contrast to ATP, which is immediately depleted after creation, plants employ the sugars produced in the Calvin cycle to store energy over the long term.
The Calvin cycle's primary job is to produce three-carbon sugars, which are then utilised to make other sugars including glucose, starch, and cellulose.
Therefore, no sugar would be produced by the plant if a herbicide prevented the Calvin cycle from starting before the production of glyceraldehyde 3-phosphate (G3P).

how do you think your body prevents your cells from shrinking or swelling due to osmotic gradients across the plasma membrane?
Your body prevents your cells from shrinking or swelling due to osmotic gradients across the plasma membrane by maintaining a proper balance of water and solutes within the cells.
Body balance can be achieved through the process of osmoregulation, namely the process of regulating fluid concentration by balancing the intake and output of body fluids by cells. This involves the movement of water and plasma membrane solutes to maintain osmotic balance.
One way that osmoregulation is achieved is through the use of aquaporins, which are special proteins that allow water to pass through the plasma membrane more easily. This helps to maintain the proper balance of water within the cells. Another way that osmoregulation is achieved is through the use of ion channels, which allow ions to pass through the plasma membrane. This helps to maintain the proper balance of solutes within the cells. Overall, the process of osmoregulation is essential for maintaining the proper balance of water and solutes within the cells, which helps to prevent the cells from shrinking or swelling due to osmotic gradients across the plasma membrane.

Why cartilage repairs slowly after adolescence?
Due to its avascularity and less ordered microarchitecture than bone, cartilage is a flexible connective tissue that differs from bone in a number of ways.
The chondrocytes are dispersed and fixedly positioned within a matrix that is held together by collagen and elastic fibres. Due to the lack of innervation, diffusion is the only way for nutrients to reach the cartilage. It recovers quite slowly as a result of this. Chondrocytes, chondroitin sulphate, the ground material, and perichondrium, the fibrous sheath, are the three main cell types in cartilage.
The process of chondrogenesis is used to create cartilage from the mesoderm germ layer.

heat is capable of causing a change in the 3-d shape of a protein. when this occurs, we describe the change as:
A protein's 3-D shape can be altered by heat. We refer to that as "denaturation" when it happens.
A biological process called denaturation changes the molecular makeup of proteins. To achieve denaturation, many of the weak connections or links that give proteins their highly organized structure in their initial (natural) state must be broken. The majority of denatured proteins are insoluble and have a looser, more erratic structure. Denaturation can be caused by a variety of factors, including heating, contact with alkalis, acids, urea, or detergents, as well as strong shaking. When the denaturing agent is withdrawn and the conditions that favor the native form are once again available, some proteins can reassemble into their original structure.
