Answer:

peer review =D

Explanation:

Peer review. This is the basis of much of the scientific method: repeatability. The concept of peer review allows for other researchers to test to make sure a paper's claims are valid and that the methods used were sound and verifiable.

NAME all the steps of Photosynthesis. What is Produced in Each Step? What are the Reactants Used in each step? What is the Final

bonufazy [111]

Answer:

1.The light-dependent reactions;

The light-independent reactions, or Calvin Cycle

2.Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP. The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.

3.In production, a final product, or finished product is a product that is ready for sale. For example, oil is the final product of an oil company. The farmer sells his vegetables as his final product, after they have been through the whole process of growth.

Describe how the release of the neurotransmitter, dopamine, can result in addiction to tobacco products.

DaniilM [7]

Dopamine is a chemical released by neurons to send signals to other nerve cells. the brain includes several distinct dopamine pathways, one of which plays a major role in reward motivated behavior.
smoking is a habit, in a habit there is the cue, routine, and reward. with smoking the cue can be different things, most commonly stress or anxiety. the routine how you react to those cues, the reward is the chemical 'triggers' that are pulled inside you're brain leaving you feeling calm, happy, or relieved, etc.

Explain how water's cohesive and adhesive properties are a result of its bonding among the atoms

vladimir1956 [14]

Water is a unique molecule which contains inter-molecular forces like vandar wall's forces and hydrogen bonding that results in extremely strong bonding forces among water molecules.

Cohesion and adhesion are the properties of water which refer to the fact that water molecules are not only very strongly attracted to water molecules but also to other polar molecules of any type.

This is the cohesive nature of the water which makes water a water drop and it is the adhesive nature of water due to which water takes the shape and available space in a glass or jar of water .

How these properties are a result of bonding between atoms?

Cohesive properties:

We are well aware of the fact that water is composed of one atom of oxygen and two atoms of Hydrogen.
The two hydrogen atoms align themselves in such a way that oxygen is in middle of them. Due to great electronegativity difference Oxygen gets a partial negative charge while Hydrogen atoms get partial positive charges.
Now one oxygen atom of one one water molecule attracts the partial positive charged hydrogen atom of another water molecule, and this attraction causes the bonding. This type of inter-molecular forces of atom gives water cohesive properties.

Adhesive properties:

If we talk about adhesive properties through which water is attracted to other materials of polar nature, these adhesive properties are also due to same nature of bonding.
Any polar compounds can easily get bonded with water due to polar nature of water molecules. You can see the attached figure for better understanding of bonding properties of water.
