An organism must has a large surface area to volume ratio in order to exchange material easier
in animals erythrocytes have a flat concave shape that allows them to carry more haemoglobin and also increases its surface area to volume ration so that the length and availability of a surface is less for the materials to travel
multi cellular organisms tend to have flat and elongated respiratory surfaces to allow for a higher surface area to volume ratio in order to increase the rate of gas exchange
the ilium in most mammals is flat and elongated and is covered with microvilli to increase surface area and to reduce the cells volume therefore reducing its surface area to volume ratio
hope that helps
The best way to identify a mineral is the color of the mineral. The color of the minerals with different impurities is different. The pink color of the rose quartz and the gray color of the smoky quartz indicates that they contain different impurities. The impurities are the main factor behind the color of any mineral.
Hence, the correct answer is 'Color is the best way to identify a mineral'.
Answer:
Phenotypic approach for bacterial identification
Explanation:
Bacterial identification can be done by conventional methods, which are based on phenotypical characteristics. These methods are much affordable and reasonable.
<u>Phenotypical identification</u> is based on bacteria´s observable characteristics, such as their morphology, development, and biochemical/metabolic properties.
It is important to consider that these methods do not provide absolute certainty. They can only indicate the genera or species to which the bacteria under study may belong.
Some primary evidence is usually used for fast bacteria identification:
- Gram staining,
- morphology,
- growth at different media or different incubation atmospheres,
- glucose fermentation,
- spores production,
- motion,
- aerobiosis/anaerobiosis,
- among others.
Knowing that the bacteria in the exposed example was isolated and grown in culture, then Gram-stained and tested for biochemical reaction, we can assume that the approach for its identification is <u>phenotypic</u>.
