Answer:
Dark beetles were more camouflaged to their new environment and were able to survive longer in order to reproduce.
Explanation:
The key here is "A lot of the brush has been burned away and the ground in the ecosystem is much darker in color due to the fire."
C. Macrophages
When Macrophages approach a foreign pathogen they ingest the pathogens through phagocytosis, the Macrophages show the foreign antigen proteins on their cell surfaces.
The Helper T Cell recognizes the antigen on the surface of the macrophage and starts an immune response to the invading pathogen by sending out a chemical message
After that the B-cells produce antibodies that are specific to the antigens of the pathogens that slow them down so the macrophages can engulf them.
The main three theories are that - all organisms are composed of cells- the cell is the basic unit of structure and organization in organisms- All cells come from pre-existing cells
Answer:
They take the carbon dioxide, water and sunlight they take in from their leaves to make food
DNA and RNA
Transcription. During the process of transcription, an enzyme called RNA polymerase binds to DNA at a gene's promoter, then begins unwinding the DNA and making a complementary strand of RNA from the exposed DNA template. Depending on the gene being transcribed, the result can be a molecule of mRNA (messenger RNA), tRNA (transfer RNA), or rRNA (ribosomal RNA). Each type of RNA performs a specific function later in translation.
rRNA
Ribosomal RNA (rRNA) along with ribosomal proteins make up ribosomes, the "workbenches" on which polypeptides (proteins) are synthesized. It turns out that it is actually rRNA, and not a protein, in the large subunit of the ribosome that performs the peptidyl transferase function of linking amino acids together via peptide bonds. In eukaryotes, the genes coding for rRNAs are located in the nucleolus of the nucleus. A ribosome has 3 binding sites: an A (aminoacyl) site, a P (peptidyl) site, and an E (exit) site.
mRNA
The message carrying the information needed to make a particular polypeptide exists in the mRNA molecule. It binds with a ribosome and the ribosome starts reading it one codon - 3 consecutive mRNA bases - at a time. Each of the possible 64 codons codes for a particular amino acid, or for a release factor (in which case it is a STOP codon). So the order of bases in the mRNA specifies the order in which amino acids are linked together to form a polypeptide.
tRNA
A tRNA molecule has 2 main sites. At one end it has an amino-acid attachment site and on the opposite end it has a 3-base anticodon. An enzyme (an aminoacyl-tRNA synthetase) recognizes the type of tRNA and attaches the appropriate amino acid to it, at which point the tRNA is said to be charged. Charged tRNA molecules "bump into" the empty ribosome A site, but only if there is a complementary match between the mRNA codon associated with that site and the anticodon on the tRNA does the charged tRNA dock.
Hopefully, that's enough...
