The third one,
Autotrophs use a process called photosynthesis to make their food. In photosynthesis, autotrophs use energy from the sun to convert water from the soil and carbon dioxide from the air into a nutrient called glucose. Glucose is a type of sugar. The glucose gives plants energy. Plants also use glucose to make cellulose, a substance they use to grow and build cell walls.
A) <u>Mutation</u> is the original source of variations for plants and other organisms which develops differences among their respective species
Explanation:
Genetic variation leads to the natural differences between each individual and among individuals of a species. The main cause for this variation is due to alleles that cause variations in the composition of genes or the DNA sequences.
A mutation is a genetic variation which leads to the creation of a new allele in a species population. Each variation in the DNA sequence leads to an allele formation and each allele leads to a difference in character or trait between individuals since they are the alternate version of the original genes.
Although genetic variations could be brought about by crossing over, random fertilization, or independent assortment; mutation is the original source because it provides the basic raw material for all the evolutionary changes.
The provided question is incomplete, the correct and complete question is as follows:
Choose the answer that best completes the sentence below.
Scientists group materials together ____________ it is easier to compare and study them that way.
A however
B but
C although
D because
Answer:
The correct answer is - option D because.
Explanation:
Researcher and scientists tries to group material together on their similarities and difference to one another which makes it easier to study and compare various type of materials.
It is the one of major reasons to differentiate materials between groups like liquids state, gases state, plasma state and solid state materials. One can easily see the difference and comparison is very clear on this type of grouping of materials.
Thus, the correct answer is - option D.
