Answer:
A
Explanation:
Trees and other plants absorb carbon dioxide from the atmosphere as they grow. This is converted into carbon and stored in the plant's branches, leaves, trunks, roots and in the soil. Cutting down of trees without allowing them to regrow, the carbon stored is released to the atmosphere in form of carbon dioxide which contributes to as much as 30 percent of global greenhouse-gas emissions.
<h2>Three limitations of Tri-component Model </h2>
There is usually discrepancy with behaviors and attitudes of the individuals.
- That is the reason there are the attitudes in which effective component, behavioral component and cognitive components.
- The sensitive and emotional reactions or feelings of an individual with one another. Though when an individual behaves with others through actions.
- The third limitation is when a person has a belief about anything.
These above are three limitations of the tri-component model.
The circulatory or cardiovascular system's ability to deliver oxygen throughout the body depends on proper functioning of the respiratory system. The interactions between the cardiovascular and respiratory systems are best demonstrated by following the path of a red blood cell starting in the heart and traveling through the lungs.
A red blood cell that has just returned from delivering oxygen and that has brought back carbon dioxide would be in the right upper chamber of the heart or in the right atrium. When the atrium contracts, the cell is pumped into the right lower chamber of the heart, or the right ventricle. When that ventricle contracts, the red blood cell is pumped out of the heart through the pulmonary artery to the lungs.
In the lungs, the red blood cell enters tiny blood vessels that come into close contact with the walls of the alveoli air sacs of the lungs. The carbon dioxide in the red blood cell passes through the walls into the alveoli while the oxygen in the alveoli air passes into the red blood cell. The red blood cell then returns to the heart via the pulmonary vein.
From the pulmonary vein, the red blood cell enters the left atrium of the heart and then the left ventricle. The part of the heart muscle powering the left ventricle is very strong because it has to push the blood out to the whole body. The red blood cell is pumped out of the left ventricle via the aorta artery and eventually reaches the capillaries leading to the individual cells. There the cells absorb the oxygen from the red blood cell and pass on their waste carbon dioxide. The red blood cell returns to the right atrium of the heart via the veins to complete the cycle.
These circulatory and respiratory system interactions are ones that humans and higher animals such as mammals and birds share and that represent one of the basic functions of their bodies. Only when these two systems work and interact properly can the human or animal carry out other functions such as looking for food or reproducing.
Answer:
Explanation:
Autonomic neurotransmitters are the chemicals that are involved in the transmission of the neural signals in tne autonomic nervous system .The autonomic nervous system consist of the sympathetic (adrenergic)and parasympathetic (cholinergic)system and the receptors are alpha,beta and muscarinic ,nicotinic respectively. These receptors are found at various sites and elicit a variety of actions in the body. The main neurotransmitter of the adrenergic system is the epinephrine or non epinephrine and for the cholinergic system is acetylcholine.
All preganglionic neurons use ACh as the neurotransmitter

According to the science journal of mathematically correct science the entire cell would break down because of all the substances passing through it. Therefore after a while there would be no cell and the animal or plant would no longer exist. -approved by the scientists of massachusets - written by proffessor Gordon amphion
