32
Explanation:
Meiosis always has half of the chromosomes as mitosis. Hope that this helps you and have a great day :)
Most metamorphic processes take place B. a few kilometers below Earth’s surface.
<h3>Further explanation
</h3>
Metamorphism is the change of minerals or geologic texture in pre-existing rocks without the protolith melting into liquid magma. Metamorphism often occurs on two scales: contact and regional. Contact metamorphism occurs locally in areas adjacent to igneous intrusions or in areas that are in contact with hot water known as hydrothermal fluids. Whereas regional metamorphism occurs over much larger areas such as rising mountain ranges, large igneous intrusions can form and warp overlying strata increasing the pressures above the intrusion. Regional metamorphism usually produces foliated rocks such as gneiss and schist.
There are other ways that metamorphic rocks can form, Dynamic metamorphism. Dynamic Metamorphism also occurs because of mountain-building. The huge forces of heat and pressure cause the rocks to be bent, folded, crushed, flattened, and sheared.
Metamorphic rocks form when increased heat and pressure force physical changes in the crystalline structure of an existing rock. Under the right conditions, any type of rock can become a metamorphic rock including igneous rocks, sedimentary rocks, and even other metamorphic rocks. Therefore metamorphic processes result due to intense heat and high pressure below the Earth's surface.

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>.
Answer:
The traits are only slightly evolving due to the small changes in the genotypic and allelic frequencies between both generations.
