The analgesic effects of chinese acupuncture can be reversed by __________. dopamine serotonin acetylcholine naloxone
wlad13 [49]
The analgesic effects of Chinese acupuncture can be reversed by NALOXONE.
Naloxone is an endorphin antagonist, that is, it functions by binding competitively with opiod receptors with higher affinity than opiod agonists. Opiod agonists are those drugs that are pain killers and they are used to relieve pain. Opiod antagonist are drugs that work against opiod agonists and prevent them from carrying out their functions. Thus, the analgesic effects of Chinese acupuncture can be canceled out by naloxone drug, which is an opiod antagonist.

Sonja [21]

1. taxonomic category within a kingdom-phylum

This taxonomic category is at level below Kingdom and above Class (e.g Arthropoda, Chordata, Mollusca)

2. plant that lives on decaying organic matter-saprophyte  

Saprotrophic plants or saprophytes use saprotrophic nutrition meaning that have extracellular digestion to process death organic matter.

3. break down of complex molecules into simpler ones- fermentation  

Fermentation is a metabolic process that breaks down organic substrates in order to obtain energy. These processes are performed without the presence of oxygen (anaerobic processes).

4. multi-nucleated thread-like structures of fungi hyphae

This is one of the basic structural unit of fungi-long, filamentous structure that can form network-micelium. It is used for vegetative reproduction.

5. mycelia responsible for obtaining food from non-living organic material rhizoids

Rhizodis are unicellular or multicellular stuctures (branching hyphae) found in fungi that are similar to root hairs of plants. These structures are involved in saprotrophic nutrition of fungi.

6. asexual reproduction of yeast budding  

Budding is a type of asexual reproduction in which a new organism develops from some generative anatomical part of the parent organism.

7. a group of hyphae mycelia

Mycelum is fungi’s vegetative body that consists of network of branching hyphae.

8. reproductive cells which can tolerate bad conditions spores

Spores are reproductive structure, part of the fungi life cycle, that can be involved in sexual or asexual reproduction, vary in structure that are formed in. Spores are usually haploid and unicellular.

9. structures which house the reproductive formation fruiting

Fruit is a structure in flowering plants that contains seed and it is responsible for seed dispersal and nutrition.

10. mutually positive relationship between two species symbiosis  

Symbiosis is biological interaction between two species that can be mutualistic, commensalistic, or parasitic. More specifically, symbiosis refers to positive interaction for both members of it.

11. plant or animal which supports a parasite host

Which statements describe the movement of blood through the heart? Check all that apply. 
vlada-n [284]

Answer:

The correct answer would be Atria push blood into the ventricles and Ventricles push blood out of the heart.

In humans, four chambered heart is present with two atria and two ventricles.

Deoxygenated blood from all over the body is passed into the right atrium through vena cava (superior and inferior).

Simultaneously, oxygenated blood from the lungs is passed into the left atrium of the heart with the help of pulmonary vein.

Both the atria contract at the same time to drain their blood into respective ventricles.

The ventricles undergo relaxation while receiving blood.

The valves present between the atria and ventricles (tricuspid and bicuspid valve) ensures that the blood flows in one way direction only. They shut down as the ventricles contract and produce the sound "lub".

The ventricles contract simultaneously to pump blood out of the heart. The right ventricle pumps deoxygenated blood into pulmonary artery which takes the blood to the lungs for oxygenation.

The left ventricle passes the oxygenated blood through aorta to all the parts of the body.

The pulmonary and aortic valves prevent the back flow of blood and shut at the same time which creates second sound called as "dub".

Substances like oxygen pass through the cell without the use of energy and move from an area of high concentration to an area of
ki77a [65]

Answer:

Diffusion

Explanation:

As substances like oxygen are non polar and are not dissolved in water they can diffuse through the cell membrane without the need of channel proteins whereas polar molecules would be repelled by the hydrophobic tails of the phospholipid bilayer an would need a channel protein
