The sentence that best explains why the native Australian dung beetles were not doing the job is "Cow dung is not part of any native Australian species niche." The beetles in Australia had formed alongside the kangaroos and wombats. When the cattle were brought to Australia in the 1880's by European settlers, the beetles were not used to the texture of the dung. It was much different and the dung was not decomposing. Native beetles were not using this dung as a feeding source. This left the cattle not feeding in the pasture because they won't eat near the dung. This reduced the cattle grazing land.
It acts as an accessory pigment! Hope this helps! Also sorry that it took 11 hrs. for people to answer! =)
Answer:
Explanation:
The genes in DNA encode protein molecules, which are the "workhorses" of the cell, carrying out all the functions necessary for life. For example, enzymes, including those that metabolize nutrients and synthesize new cellular constituents, as well as DNA polymerases and other enzymes that make copies of DNA during cell division, are all proteins.
In the simplest sense, expressing a gene means manufacturing its corresponding protein, and this multilayered process has two major steps. In the first step, the information in DNA is transferred to a messenger RNA (mRNA) molecule by way of a process called transcription. During transcription, the DNA of a gene serves as a template for complementary base-pairing, and an enzyme called RNA polymerase II catalyzes the formation of a pre-mRNA molecule, which is then processed to form mature mRNA (Figure 1). The resulting mRNA is a single-stranded copy of the gene, which next must be translated into a protein molecule.
During translation, which is the second major step in gene expression, the mRNA is "read" according to the genetic code, which relates the DNA sequence to the amino acid sequence in proteins (Figure 2). Each group of three bases in mRNA constitutes a codon, and each codon specifies a particular amino acid (hence, it is a triplet code). The mRNA sequence is thus used as a template to assemble—in order—the chain of amino acids that form a protein
But where does translation take place within a cell? What individual substeps are a part of this process? And does translation differ between prokaryotes and eukaryotes? The answers to questions such as these reveal a great deal about the essential similarities between all species.
Answer:
A surface wave is a wave that moves along the interface of two different materials, like air and water.
