A dihybrid cross is defined as a breeding experiment involving parental generation chromosomes that have two contrasting traits. The individual organisms involved in this can be either homozygous or heterozygous.
This kind of cross pollination experiments led to the development of George Handel's Law of Independent Assortment.
Hope it helps.
False it is does not have plants it can be release oxygen gas to the atmosphere

so in this case it should be option 2.

Answer:
The statement that supports the idea that the genetic code is common to all living things is All living things have genes that use the same nitrogenous bases (choice B).
Explanation:
All living organisms possess DNA, a nucleic acid molecule that contains all the genetic information of living beings. This information is transcribed into mRNA, where it becomes the genetic code that determines the synthesis of biomolecules, such as proteins.
The DNA molecule is made up of sequences of four nitrogenous bases: adenine, guanine, thymine and cytosine. <u>These nitrogenous bases are common in the DNA of all living organisms</u>.
Since genes consist of DNA fragments, with specific sequences of the same nitrogenous bases, then it is true to state that all living things have genes that use the same nitrogenous bases.
The other options are not correct because:
<em> A. Living organisms have different ways of reproduction.
</em>
<em> C. The way living things use energy is different, and there is no evidence that the genetic code is common to all of them.
</em>
<em> D. The way organisms adapt is not supported by the fact that they possess a common genetic code.</em>
