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.
Answer: I think you have to divide each level by 10 so the first level will stay the same and the rest go like this
3,500,000 divided by 10 equals 350,000
350,000 divided by 10 equals 35,000
and 35,000 divided by 10 equals 3,500

Adaptations increase the probability of an organism surviving and reproducing in a specific environment.
The 5 different living things chosen based on my location are:
- Birds
- Lizard
- Snakes
- Rats
- cockroaches
Yes, the structure of one organism's parts work do work with a different organism such as the snakes and lizards scales does the same function.
<h3>What are some of the structures of these living things?</h3>
The structure and how the structure relates to the organism's function are;
- Birds - The beak is used for picking food, sallow and to catch insects.
- Lizard -Scales on their outer layer skin that is dry and has some levels of keratin and it act to protect their body and hinder water loss.
- Snakes - Scales on their outer layer skin that is dry and has some levels of keratin and it act to protect their body and hinder water loss.
- Rats - Teeth consist of a pair of incisors as well as molars for picking insect, chewing and eating.
- Cockroaches - has antennae for sensitivity as well as strong mouthparts that is often used scraping and chewing food.
Therefore, The 5 different living things chosen based on my location are:
- Birds
- Lizard
- Snakes
- Rats
- cockroaches

The small cells of bacteria that lack nuclei are termed as PROKARYOTIC CELLS.
Prokaryotic cells are the bacterial cells that do not have true nucleus. These cells contain genetic material naked in the cytoplasm and is referred as nucleoid that lacks a nuclear membrane.
