You can infer that the birds once had a common ancestor but became separated. Mutations in copying their genes stacked and caused changes in the beaks so the birds could be more well off or better adapted in their new environment.
Answer:
The process of photosynthesis is complex. Sunlight energy is converted into chemical energy by using chlorophyll, which is what gives plants their green color. Chlorophyll absorbs red and blue light and uses the energy to convert water and carbon dioxide into glucose then releases the unused components such as oxygen.
Answer:
Regulatory sites e.g enhancers and silencers
Explanation:
Gene expression involves the synthesis of gene products usually proteins and RNA. However, a certain product might not be needed at all or in small quantity. Gene regulation mechanism is the process that makes this happen. Gene regulation is the mechanism that acts to induce or repress the expression of a gene.
Gene regulation involves controlling the rate and manner of gene expression which is achieved through a set of regulatory proteins called transcription factors. Transcription factors bind to specific regulatory nucleotide sequences and help to turn "on or off" specific genes in the DNA.
Transcription factors can either be ACTIVATORS or REPRESSORS depending on whether they boost or inhibit gene expression. The binding sites for these regulatory proteins called TRANSCRIPTION factors are the regulatory nucleotide sequences on the DNA called enhancers and silencers.
Answer:
The RNA carries out these instructions; it copies and transfers the genetic code from the DNA to ensure the relevant proteins are made. So just think of it as “DNA makes RNA make proteins”. Whereas DNA stands for deoxyribonucleic acid, RNA stands for ribonucleic acid.
Explanation:
Nooooo! Please, don't feel that way. I'm sorry you have to go through something like that. If you want someone to talk to everyday and tell me about your day then you can always talk to me or add me! Just know that I'm always here to love you, and support and care for you!
