Answer:
(a) Gg × Gg; (b) genotypic = 1:2:1, phenotypic = 3:1
Explanation:
a) A cross between two gray seeded plants produces progeny with gray and white seeds in 3:1 ratio (302:98=3:1). This means that the parent plants are heterozygous and each has at least one recessive allele. If the allele "G" is responsible for gray seed and the allele "g" imparts white color to the seeds, the genotype of the heterozygous parents would be "Gg".
b) A cross between two heterozygous gray seeded parents would produce progeny in following ratio:
Genotype ratio= 1 GG: 2 Gg: 1 gg
Phenotype ratio= 3 Gray: 1 white

Explanation:
<span>In chemistry, </span>activation energy<span> is a term introduced in 1889 by the Swedish scientist Svante Arrhenius to describe the minimum </span>energy<span> which must be available to a chemical system with potential reactants to result in a chemical reaction. That is the definition of it, but I have no idea what examples you want me to see are called energy of activation</span>
The word hurricane originated from the name of the Mayan god hurcan
Starting with a newly divided cell, the correct sequence for the human cell cycle phases are interphase followed by mitosis and then cytokinesis.
Interphase of the cell cycle does not involve any cell division. It is a period of growth and replication of the nuclear DNA. The cell prepares for the division in this stage. Interphase is further divided into the G1, S and G2 phases. Mitosis is the next phase of the cell cycle which involves the division of the cell in order to form daughter cells. Mitosis is further divided into the prophase, metaphase, anaphase and the telophase. Cytokinesis marks the end of the mitosis and this is where the cell actually separates to produce two daughter cells.
