i dont know actually but i belive in you . rremeber that you atre great and beutiful. i love you
Explanation:
Skin nerve impulses initiated in mechanoreceptors are transmitted along type B fiber
<h3>What are mechanoreceptors ?</h3>
These detect mechanical deformation e.g. touch or pressure within the skin; stretch receptors in muscles. * mechanoreceptor cells answer a change in the external stimulus (pressure, temperature, etc) by producing voltage pulses across neurons (i.e. generator potentials)
<h3>Where are mechanoreceptors found?</h3>
Mechanoreceptors are sensory neurons or peripheral afferents located within joint capsular tissues, ligaments, tendons, muscle, and skin. Four primary sorts of afferent mechanoreceptors are commonly present in noncontractile capsular and ligamentous structures in human joints: types I, II, III, and IV
<h2>What sends impulses from the skin?</h2>
First-order neurons receive impulses from skin and proprioceptors and send them to the medulla spinalis . They then synapse with second-order neurons. Second-order neurons sleep in the dorsal horn and send impulses to the thalamus and cerebellum

A. A describes the effect of light intensity on photosynthesis.
Answer: A
Explanation:
In plants and other primary producers, photosynthesis is a biological mechanism that is vital to energy production. Energy-containing carbohydrates are derived from light, water and carbon dioxide in the form of glucose molecules.
The waste product oxygen is released as a result. Photosynthesis depends on many variables, including:
carbon dioxide concentration,
ambient temperature
and light intensity
It is a rate-limited reaction. Since photons or particles of light provide the energy required for the reaction, high intensities of light increase the photosynthetic rate. From the graph shown, as the intensity increases steadily, so does the rate- but at too high of an intensity, it ceases to affect the rate of photosynthesis, which becomes constant or plateaus.
Beyond this point, either the supply of carbon dioxide or the temperature limits the reaction. For instance, at high intensities tissues may even be damaged by high temperatures or heat.
The answer is cell wall!!!XD
Hope this helped!!!XD
