With many fossil fuels, such as coal, they contain some form of carbon, and when the fossil fuels are burned, they combine with oxygen to form CO2 (carbon dioxide) which is then released into the atmosphere.
I think the answer would be down
The ancestors of different mammal groups became isolated from one another. Each landmass took a different unique array of species.
Answer:
Allele is the form in which sequenced information within a single gene can be expressed. One allele is paired with another within a gene, which is part of a chromosome and which determines the expression of specific traits.
Explanation:
The genetic information is contained in the DNA, and each molecule of this nucleic acid forms a chromosome containing genes, fragments of the DNA of the chromosome with a sequence of nucleotides for the synthesis of specific proteins.
Genes determine morphological or functional features of a living being. Each gene contains two alleles for each trait it determines, the alleles being different sequences of nucleotides that constitute different ways in which a trait can be expressed.
<h3>How are the alleles related to genes, chromosomes and traits?
</h3>
Each gene contains two alleles, either the same or different, with the sequence of nitrogenous bases to determine the possible ways in which a trait is expressed. The different sequences of the alleles can produce specific modifications of the function of that gene, conditioning the different forms of expression of a trait.
Genes, which contain alleles, are found within a chromosome, at a specific location called a locus.
The pons. Hope this helped!
