Is photoshynthesis a chemical change ? yes or no ?

Biology
1 answer:
scZoUnD [109]3 years ago
4 0

Answer:

Yes, photosynthesis is a chemical change

Explanation:

Photosynthesis is the process through which plants convert light energy into chemical energy. Here is the chemical reaction involved: water and carbon dioxide combine to form glucose and oxygen. Since new chemical species are formed, photosynthesis is clearly a chemical change.

Match the following terms and definitions. 1. an electrical nerve impulse sent by nerve fibers to the central nervous system for
vladimir1956 [14]

Answer:

1. an electrical nerve impulse sent by nerve fibers to the central nervous system for interpretation. <u>Action potential. </u>

2. neurons that detect chemicals such as those found in food. <u>Chemoreceptors. </u>

3. type of eyes many arthropods have; eyes that protrude outward and consist of many lenses. <u>Compound eyes. </u>

4. the structure that gives the response to an environmental change.<u> Effector</u>

5. neurons that detect electrical fields. <u>Electroreceptors. </u>

6. secretion of hormones into the blood stream to affect distant processes. <u>Endocrine.</u>

Explanation:  

An action potential is a change in the internal charge of a cell due to depolarization. These changes allow the transmission of a message from any part of the body to the central nervous system. The central nervous system will interpret the message and will give a response.

There are different types of receptors in our bodies. Chemoreceptors are the ones that detect chemicals and produce an action potential or a neurotransmitter. These receptors respond to chemicals. Another type of receptor is the electroreceptors. They detect electrical fields and are only on the skin of aquatic animals.

Compound eyes have a large number of ommatidia. As a result, the anthropods with this type of eyes have a large view angle. In other words, every ommatidium sees an image, and the final product is a combination of all of them.

The effector is the structure that gives an answer once an affector has sent the message to the nervous system that there was a change in the environment.

There are different kinds of secretions, autocrine, paracrine, and endocrine. In the endocrine secretion, the gland secrets hormones into the bloodstream so that they can travel long distances up to their target cell, which is far from the gland.

What would be the best explanation for why myelinated fibers conduct signals faster than unmyelinated fibers?
Sliva [168]

Answer: The diffusion of ions along the axoplasm is faster,in myelinated compare to unmyelinated,

Neurons are the structural and functioning units of nervous system.They are the vehicles for transmission of impulses as electrical signals from one part of the cells,and from one part of the body to another.

The basic structural components of a typical neuron are the cellbody, the axon, and the dendrites.

Based on structure neurons are classified as myelinated and unmyelinated.This is based on the the surrounding layer of myelin sheath around the axon. The myelin provides the insulating layer for the axon.And ensures fast movement of impluses.

In myelinated neurons the myelin sheath are interrupted at intervals by gaps along the length of the axon called Nodes of Ranvier. These gaps contains more Na-K channels for influx and out-flux of K and Na+ ions for transmission of impulses.

The cytoplasm of axon is called axoplasm,Since this is surrounded by myelin sheath which contains Na-K+ channels,The rate of diffusion of ions along  these channels is faster for depolarization to take place than in unmyelinated neurons. Inaddtion as these ions  diffusion increases,its jump faster at the nodes of Ranvier (saltatory conduction) to the next axoplasm which further speed up the rate of transmission.

Unmyeinated lacks myelin sheath,therefore the exchange and  the rate of diffusion of ions along the axons is low.

Iguanas and similar animals are members of a group called reptiles. How do reptiles differ from other animals
Papessa [141]
They have scales instead of skin or fur, as well as some being able to swim in water and walk on land. Many are poisonous and have several different tactics for catching prey from insects to small creatures like birds or mice. The Komodo dragon is a large reptile that has poisonous saliva which it uses to stun its prey.
