Explanation:
Heterotroph. 100% correct. Goodluck. glad to help.
DNA is the main type of genetic material found in a cell. In addition,
it is found in the nucleus of the cell, so (D) is correct. DNA in the
nucleus is used in replication (through mitosis and meiosis) via
daughter cells to continue cell growth.
Answer:
Maintain homeostasis.
Explanation:
Homeostasis is the ability to maintain a stable internal state. All organisms need to maintain homeostasis and must regulate their internal environment to process energy and stay alive. Rubbing your arms and shivering is your body's natural response to getting colder and trying to warm up. The students body is responding to the cold environment in order to maintain homeostasis - in this case the proper body temperature of 98.6°F or 37°C.
Answer:
The biological level of organization represented by all of the three steps of gene expression products is <em>the central dogma of molecular biology.</em>
Explanation:
DNA is divided up into functional units called genes. Each of them provides instructions for a functional product, that is, a molecule nedeed to perform a job in the cell. In many cases, the functional product of a gene is a protein.
The functional products of most known genes are polypeptides. Genes that specify polypeptides are called protein-coding genes.
Not all genes specify polypeptides. Instead, some provide instructions to build functional RNA molecules, such as transfer RNAs and ribosomal RNAs that play roles in translation.
The construction of polypeptide involves two major steps: transcription and translation. During the transcription, the DNA sequence of gene is copied to make an RNA molecule and in translation the sequence of mRNA is decoded to specify the amino acid sequence of the polypeptide.
