When hydrogen and oxygen combine to form water. This process is called as a chemical reaction and water formed in the reaction is called the product. Thus, the correct option is A.
A chemical reaction is a process which leads to chemical transformation In this process, two or more reactants combine and undergo reaction to form the product. The product formed is different from reactants in chemical properties.
There are four main types of chemical reactions. These are as follows: 1. Synthesis reactions, 2. Decomposition reactions, 3. Single-replacement reactions, 4. Double-replacement reactions.
An enzyme is a biocatalyst which is when added to a chemical reaction increases the rate of a reaction. Catalysts are the chemical compounds which decreases the activation energy and hence the formation of product increases.
Therefore, the correct option is A.

Based on the importance of variation, brightly colored cardinals are better able to survive and to reproduce than darker cardinals.
Variation is the differences in characteristics between individuals of the same species.
Based on the importance of Charles Darwin's theory of evolution, an example that can be explained by individual variation is;
Brightly colored cardinals are better able to survive and to reproduce than darker cardinals.

was supported by Galileo
stated that the earth rotated around the sun
all of the above
which one
Answer:
Option D, All of the above
Explanation:
The heliocentric model was first proposed by Nicolaus Copernicus but since his findings were based on previous studies and researches, his theory of heliocentric model of universe was rejected in its early phase. However, later on Galileo supported the Copernicus theory when he visualized the universe through his telescope. As proposed and seen by Galileo , it was established that Heliocentric model is the correct model of Universe where all planet including earth rotate around the sun.
A homozygous green (yy) pea plant is crossed with a heterozygous yellow (Yy) pea plant. The phenotypic ratio of the offspring is 50 percent Yy and 50 percent yy.
Further Explanation:
Genotypes help in the genetic makeup of any individual. Phenotype describes as a physical characteristic of an individual. The genotype is responsible for the phenotypes of any individual. If two copies of the same alleles present in an organism, its genotype is called homozygous. If two copies of different alleles present in an organism, its genotype is called heterozygous.
When a homozygous dominant individual is crossed with the homozygous recessive individual the resultant offspring has the genotype which is heterozygous and phenotype which is dominant. All possible genotypes of the parent as well as offspring are graphically represented in a Punnett square.
In the given punnet square below, the parent homozygous green plant having a genotype yy is crossed with the parent heterozygous yellow plant having a genotype of Yy. The resultant offspring of filial generation tends to be 50 percent of Yy which means heterozygous and 50 percent yy which means homozygous.
