They break down the scraps of food and such. if we did not have decomposers then the earth would be over ran with dead plants and animals and it would not be a nice place to live
Answer:
Option C
Explanation:
Options for the question are
a. It demonstrated that nothing in biology makes sense except in the light of evolution.
b. It demonstrated that species arise from other species.
c. It provided a quantifiable mechanism to explain gradual evolutionary change.
d. It was the first time that change in biological organisms was observed.
e. It was not very important to evolutionary biology.
Solution -
The term modern synthesis by coined by Julian Huxley and the goal of this synthesis was to understand and determine how genetics bring evolutionary changes in a population and with this objective it combined the Darwin’s theory of evolution and Mendel’s work on heredity. Later on scientist Dobzhansky under this synthesis found that genetic mutation causes variation through the process of natural selection and hence lead to evolutionary changes in a population even if they are isolated for a long time.
Hence, option C is correct
Answer: The correct answer is-
B. Yy
As per the information in the question, yellow (depicted by Y allele) seed color is a dominant trait whereas green seed color is a recessive trait ( depicted by y allele).
A dominant trait always masks the expression of a recessive trait.
Presence of single dominant allele ( such as in Yy, which shows heterozygous dominant genotype) in the genotype can produce a dominant trait whereas recessive trait is only expressed when its genotype is homozygous recessive (such as yy that is both alleles should be recessive allele) .
A plant with genotype Yy will form two gametes that is Y and y.
When such plants are allowed to interbreed, there is a probability of 25% of producing green seeds in the next generation.

Answer:
I believe it is C
Explanation:
Scientists are still testing this theory so I believe it is a hypothesis.
Forgive me if I am incorrect.
