<u>Answer</u>:
"It increases the mutation rate" is an advantage of sexual reproduction
<u>Explanation</u>:
The basic thing of evolution is fundamental, as it helps in generation of genetic variation on which the selection can act. Sexual reproduction leads to genetic diversity, and this genetic diversity leads to increase the mutation rate. Genetic diversity occurs because of two various cells which are combining together and biological assortment which happens at the time of cell division. Neutral genetic diversity in the population leads to high mutation rate.
Eukaryotes can’t have bacterial or archaea. This is because eukaryotes and bacterial are 2 different cells as bacteria are prokaryotes...
Answer:
Examples of environmental factors that may alter salivary peroxidase include periodontitis, oral hygiene, presence of heavy metal ions, bacteria (e.g., <em>Streptococcus gordonii</em>), anaerobic conditions, temperature, pH, etc.
Explanation:
Peroxidase is an enzyme found in all aerobic cells that act to convert toxic hydrogen peroxide (H2O2) into dioxygen (O2) and water (H2O). This enzyme plays an important non-specific defensive role against proliferating micro-organisms that cause periodontal diseases such as periodontitis, which is a serious inflammatory disease affecting the tissues around the teeth. The most common environmental factors influencing the development of periodontitis include oral hygiene, smoking and age. In this regard, it has recently been shown that there is a positive correlation between salivary peroxidase activity and periodontal health, especially in non-smoker individuals. In consequence, it is expected that smoker individuals are more prone to suffer periodontal diseases by reduction of the salivary peroxidase levels.
The major features of
schizoaffective disorder which clearly delineate it from schizophrenia are marked
symptoms of schizophrenia coupled with major depressive episode or manic
episode. Both schizoaffective disorder and schizophrenia are primary psychotic
disorders.
Answer:
The correct answer is option c. "The apparent value of KM increases with a competitive inhibitor, while it remains unchanged with a noncompetitive inhibitor".
Explanation:
The KM value in an enzymatic reaction is defined as the substrate concentration at which the half of the enzyme molecules are binding with the substrate. A way to distinguish between a competitive and noncompetitive inhibition is that the apparent value of KM increases with a competitive inhibitor, while it remains unchanged with a noncompetitive inhibitor. A competitive inhibitor would make that a higher concentration of substrate is needed, while a noncompetitive inhibitor does not change KM since the inhibitor binds to a site of the enzyme different from the active site.
