Answer: A simple word equation that can be used to describe the process of photosynthesis is carbon dioxide + water —> glucose + oxygen + water. A balanced chemical equation for the process can be written as 6CO2 + 6H2O —> C6H12O6 + 6O2. Overall, photosynthesis uses light energy to convert carbon dioxide into a carbohydrate.
Explanation:
Examples of intensive properties include:
- Boiling point
- Density
- State of matter
- Color
- Melting point
- Odor
- Luster
- Hardness
- Ductility
- Malleability
Intensive properties can be used to help identify a sample because these characteristics do not depend on the amount of sample, nor do they change according to conditions.
Extensive Properties
Extensive properties do depend on the amount of matter that is present. Examples of extensive properties include:
- Volume
- Mass
- Size
- Weight
- Length
While extensive properties are great for describing a sample, they aren't very helpful identifying it because they can change according to sample size or conditions.
Way To Tell Intensive and Extensive Properties Apart?
One easy way to tell whether a physical property is intensive or extensive is to take two identical samples of a substance and put them together.
Explanation and Examples of Physical Properties
If this doubles the property (e.g., twice the mass, twice as long), it's an extensive property. If the property is unchanged by altering the sample size, it's an intensive property.
Answer: The question is incorrect, below is the correct question
Which DNA FINGERPRINTING technique examines the length variation of DNA repeat sequences in human DNA?
The correct answer to the question is option D
mtDNA (mitochondrial DNA) analysis
Explanation: DNA fingerprinting technique is a laboratory technique used by geneticists.it entails placing of DNA samples into wells,these wells are then placed in a slab of gels and thereafter passing a current through the gel.This is done to ascertain the uniqueness of a DNA pattern and thus be able to differentiate people of same species.
There are several methods of DNA fingerprinting as outlined in the options given with the question.
In mtDNA (mitochondrial DNA) analysis,The Genetic samples are extracted from the biological materials, these samples extracted are total genomic DNA like hair,tooth or samples of blood, Several copies of these genomic DNA are then produced using a polymerase chain reaction and flanking primers inorder to examines the length variation of DNA repeat sequences in human DNA.
The answer is gene activation or repression
Answer:
The genotypic ratio shows the number of times a characteristic of an organism will be seen in the offspring when genes for certain traits are crossed.
