The results of the study would be expected to change if the same experiment were repeated with natural gas in the area of a decrease in the reaction time.

<h3>What is Reaction time?</h3>

This is the time frame between when a stimulus and a response or total time taken for a reaction to occur.

Natural gas produces steady amount of heat with a higher temperature which leads to a decrease in reaction time.

Vikki [24]

Answer:

the classification of racial types is an arbitrary, culturally specific process.

Explanation:

Racism can be defined as an act, practice or policy by an individual, group of people or institutions which typically involves promoting the ideas and belief that a race is superior in comparison with another. Thus, it simply means the believe that a particular race has dominance over another (an inferior race).

An examination of the classifications of races from around the world indicates that the classification of racial types such as Africans, Americans, Indians, Asians, Black-Americans, Hispanics, etc., is typically based on individual perception, not objective and an impulsive (arbitrary), culturally inclined or specific process.

This ultimately implies that, the classification of racial types is considered not to be based on any form of objective distinction but may be defined by a person's culture.

A culture can be defined as the general way of life of a group of people living together in a particular location or society.

Basically, culture comprises of beliefs, values, behaviors, language, dressing, cuisine, music, symbols, arts, social habits, knowledge, customs, laws pertaining to a particular group of people living together in a society.

Which factor does not greatly influence the rate of
jonny [76]

Answer:

a. transcription

Explanation:

<em>Sugar transport in phloem is referred to as pressure flow and it involves the movement of sugar through the phloem vascular tissue from the regions where sugar is synthesized (by photosynthesis) to other parts of the plant's body that require sugar.</em>

The parts of plants where sugar is synthesized (usually the leaf) is known as sugar source while the parts where they are transported is referred to as the source. Sources are usually areas of of high osmotic concentration and high water pressure while sinks are usually areas of low osmotic concentration and low water pressure.

<em>Hence, sugar transport in the phloem can be said to be influenced by the rate of sugar production at the source (rate of photosynthesis), turgor pressure as well as sugar concentration in sinks and sources.</em>

The only option that has no known effect on sugar transport in the phloem is transcription.

The correct option is a.

You are comparing a reaction that produces a chemical change and one that produces a physical change. What evidence could you us
Zina [86]

Answer:

To understand the physical change and chemical change, one needs to know what is physical properties and what is the chemical properties of a substance.

Physical property is characteristic or trait of a substance that can be observed without converting the substance to a new substance. If there is any type of change in these physical properties like changing the appearance or form of matter and does not make a new substance, takes place it is called physical change.

A chemical change is a change in the matter of a substance that creates one or more new substances. This type of change includes the formation, color, of a precipitate, change in texture, and many other changes.
