Embryonic differentiation<span> is the process of development during which embryonic cells specialize and diverse tissue structures arise. Animals are made up of many different cell types, each with specific functions in the body. However, during early embryonic development, the embryo does not yet possess these varied cells; this is where embryonic </span>differentiation<span> comes into play. The </span>differentiation<span> of cells during </span>embryogenesis<span> is the key to cell, tissue, organ, and organism identity.</span>
Answer:
The genetic code is degenerate.
Explanation:
The genetic code is degenerate: there are 64 triplets of different codons (sequence of three bases of mRNA that codes for a certain amino acid) and 20 amino acids. That is, an amico acid can be encoded by more than one codon.
Answer:
alleles-one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.
dominant- The dominant allele of the gene is inherently dominant,so it hides the presence of the recessive allele
heterozygous-having two different alleles of a particular gene or genes.
homozygous-a particular gene that has identical alleles on both homologous chromosomes
recessive-A recessive gene is a gene that can be masked by a dominant gene
Answer:
Charles Darwin was the man who came with the theory of natural selection. He witnessed finches within the Galapagos Islands and made notes on the similarities and differences of the finches across the group of islands. Each of the islands comprises finches, which were identical, however distinct in different ways.
Darwin found that the finches appeared to vary on the basis of the food sources available on each of the islands. If the prime food were seeds, the finches seemed to possess thicker beaks in order to break the seeds so that they can consume them.
On the other hand, if the prime food sources were insects, then the finches seemed to exhibit smaller and pointer beaks so that they could hold the insects readily. In this way, there is unity in diversity. All of these birds are finches and exhibited a common ancestor from which they have originated into the distinct species as mentioned.
Their variations lie in the habitats, in which they now inhabit. They had to amend with their environments in order to thrive, thus, offering diversity to unity.
