| Without it, the carbonic acid produced during breathing would remain acidic and throw an organism's system out of balance. |
|
| Each elaborates its own protein repertoire, yet all came from an egg containing the only copy of the organism's genes. |
|
| These show footprints, burrows, tracks, or other marks made during the course of an organism's lifetime. |
|
| It can be argued that the single-cell stage is the most vulnerable period in any multicellular organism's life history. |
|
| Similarly, the time to adulthood or to reproductive maturity is a key fitness component of an organism's life history. |
|
| Researchers also had to tweak the organism's DNA so it would expend most of its energy making propanediol rather than replicating itself. |
|
| During sepsis, we are learning that immune-endocrine crosstalk is not an epiphenomenon but is critical to the organism's capacity to cope with severe stress. |
|
| Some of the new genes may contribute to the organism's virulence. |
|
| The first step involves using a device called a polymerase chain reaction instrument to measure the levels of an organism's cytokines when exposed to a given material. |
|
| There is widespread consensus that an organism's lifestyle is often reflected in the skeleton at various levels ranging from gross morphology to histological structure. |
|
| Due to this extremely thin membranous tissue, a bat's wing can significantly contribute to the organism's total gas exchange efficiency. |
|
| An individual organism's phenotype results from both its genotype and the influence from the environment it has lived in. |
|
| Natural selection acts on an organism's phenotype, or physical characteristics. |
|
| The niche concept is that if an area supports an organism's need for survival then it is more likely to live there. |
|
| Also, the term adaptation may refer to a trait that is important for an organism's survival. |
|
| Starvation is a severe deficiency in caloric energy intake, below the level needed to maintain an organism's life. |
|
| As a result, many aspects of an organism's phenotype are not inherited. |
|
| Compression fossils, such as those of fossil ferns, are the result of chemical reduction of the complex organic molecules composing the organism's tissues. |
|
| Immunoassay B on the other hand may detect or measure antibodies produced by an organism's immune system that are made to neutralize and allow the destruction of the virus. |
|
| As these DNA targets can occur throughout an organism's genome, changes in the activity of one type of transcription factor can affect thousands of genes. |
|
|
|
| Brown headed the investigation that discovered the unicellular organism's proteins and genes are similar to those found in multicellular life-forms. |
|
| The organism's biochemical characteristics are summarized and compared with published reports on M mucogenicum and Mycobacterium chelonae-like organism in the Table. |
|
| Certain DNA elements such as transposons, fragments of DNA that replicate within an organism's genome, can however disrupt this functioning and disable genes. |
|
| Fitness is measured by an organism's ability to survive and reproduce, which determines the size of its genetic contribution to the next generation. |
