Answer:
First, “fire suppression” is the act of extinguishing or fighting fires, while “fire exclusion” is the defacto policy of trying to eliminate fires from the landscape using fire suppression techniques.
Primers are small snippets of DNA homologous to different regions in a target gene. For any targeted DNA gene at least two primers are necessary to delimitate a DNA variable segment targeted to be amplified.
Answer and Explanation:
The cell theory has 3 parts:
- All living things are made of cells.
- Cells come from preexisting cells.
- Cells are the basic units of life.
Since this looks like a multiple choice problem, look for any answer choice that matches one of the three parts listed above.
Hope this helps!
Answer: a. Photo-periodism
Explanation:
The relative length of the day is considered as a major factor in the development of plants, particularly in sexual reproduction. The plants were grouped considering that the flowering and fruiting occurs only when the length of the day is within certain limits so that these phases are achieved only in certain times of the year. Therefore, some species respond to long days, while others respond to short days, and still, others are capable of responding to all day lengths. The name and meaning of each group became as follows:
Short Day Plants: They are the species that bloom in smaller photoperiods than a critical maximum.
Long day plants. These are the species that bloom in larger photoperiods than a critical minimum.
Neutral day plants: They are those that bloom in a wide range of the photoperiod.
Answer:
Differences in their boiling points
Explanation:
When crude oil is distilled and separated into categories, the categories are characterized by the differences in their boiling points.
At different boiling points, each of the fraction will separate out.
- Crude oil is made up of different fractions of hydrocarbons.
- As the chain length of the hydrocarbon increases, the volatility reduces and boiling point increases.
- Components with short carbon lengths rises out from the column first and are cooled and extracted.
- The categories are thereby, classified based on differences in their boiling points.
