Answer: Qualitative data

Explanation:

Since we are informed that the scientist writes down that there was an iridescent sheen on the surface of the water, this is a qualitative data.

Starting off, the conditions required for a seed to germinate are:

Observations:

Dry cotton wool: Seeds placed here will not germinate. They will not show any changes since not all the the conditions are met. (There's no water)

Wet cotton wool: Seeds placed here will germinate since all the conditions required for germinations to take place are met.

Covered with water: The seeds will gradually start to expand. The oxygen which is dissolved in water does not enter the seed due to excess water thus preventing germination.

Answer: A disease that is not contagious is called a noninfectious disease. These diseases are not caused by pathogens. Instead, they are likely to have causes such as lifestyle factors, environmental toxins, or gene mutations. Common types of noninfectious diseases include cancer, diabetes, and immune system diseases.

Answer:

noninfectious disease is not a contagious disease. eg. cardiovascular disease, cancers, diabetes and etc

Answer:

Depending upon the country and community in which you live, the authority exercised by elected officials is defined by formal rules and informal norms of behavior that apply in that jurisdiction. Authority is the willing compliance, almost automatic, with dictates from figures to whom we grant that authority. The formal rules limiting government officials’ authority should protect citizens from abuses of that authority but informal norms may sometimes allow elected officials to get away with actions that violate those rules or, at least, bend them to their own purposes.

Rational- legal authority is practiced by elected government officials. The

practice of the people voting the officials they deem fit is referred to as

Democracy.

Democracy involves leadership of the people through laws which govern

that area. The laws  are referred to as constitution and contains the power

and authority that government officials and says what can be done by them

or not with laid down consequences if disobeyed.

Answer:

27 grams

Explanation:

27 grams of salt would still be left behind.

The dissolution of salt in water is a physical reaction and the salt can be recovered by evaporating off the water using appropriate procedures.

Provided that no part of the salt/water mixture is lost during the process of evaporation, if 27 grams of salt was dissolved initially, the same amount of salt would be recovered at the end of the separation process.

Cellular differentiation is the process in which a cell changes from one cell type to another. Usually, the cell changes to a more specialized type. Differentiation occurs numerous times during the development of a multicellular organism as it changes from a simple zygote to a complex system of tissues and cell types.
