4 0

A is incorrect. This sticking together of like substances is called cohesion. Depending on how attracted molecules of the same substance are to one another, the substance will be more or less cohesive. Hydrogen bonds cause water to be exceptionally attracted to each other. Therefore, water is very cohesive.

B is correct. The property in which water molecules stick to one another tightly. The property in which water molecules easily evaporate into a gas.

C is incorrect. In cohesion, water molecules are attracted to each other (because of hydrogen bonding), keeping the molecules together at the liquid-air (gas) interface, although there is no more room in the glass.

Discuss one of the major issues in toxicology from any perspective.
tangare [24]

A controversial issue of toxicology is the use of chemical additives in food.

Food additives are substances intentionally added to foods for the purpose of preserving, enhancing or modifying their physical, chemical, biological or sensory properties without impairing their nutritional value. However, it is necessary to control the use of these substances, as ingestion of these substances may pose health risks.

Additives are found in most processed foods, such as cookies, breakfast cereals, soft drinks, jellies, artificial juices, candies and a host of other foods in the diet of Brazilians, especially children.

Thus, its consumption should be controlled, as the health risk is confirmed by a sum of scientific studies. The three main ills associated with excessive consumption of these substances are cancer, food hypersensitivity and attention deficit hyperactivity disorder.

Some audiences are even more vulnerable to consumption, such as pregnant women, the elderly, people with little food and children under three years. In the case of children the attention should be greater because the digestive and urinary systems are not yet fully prepared to process these substances.

The more industrialized the product, the more chemical additives it will have. The ideal is to prepare fresh products at home. However, as is often not possible, it is important that you read the label and choose the products with the least additives.

How is ATP created in photosynthesis?
uranmaximum [27]

Answer:

The correct answer is option e, that is, a, b and c.  

Explanation:

The phenomenon by which green plants and other species converts light energy into chemical energy is termed as photosynthesis. During photosynthesis, the energy of the light is captivated and is utilized to transform carbon dioxide, water, and minerals into oxygen and energy-rich organic components.  

With the transport of electron through the chloroplast membrane, the energy of the electron causes the diffusion of a hydrogen ion from stroma into the thylakoid lumen, which further leads to a formation of hydrogen ion concentration gradient. This gradient ultimately results in the formation of ATP.
