The tree's life cycle, Because are world is just getting worse and worse so over time tree's will probably live less of a life then they do now.
Phenotypes, Genotypes, and Traits from Parents represented into offspring.
Answer:
They have a vacuole inside, that stored the nitrate needed to oxidize sulfide and obtain energy.
Explanation:
<em>Thiomargarita namibiensis</em> is the largest prokaryotic bacterium yet known, it has a spherical shape and reaches up to a size of 0.75 mm wide, which makes it visible to the human eye. It was discovered on the shores of Namibia and It is known as "Sulfur Pearl of Namibia," due to the sulfur granules they store inside and the brightness they produce. The problem with its large dimensions is the larger the surface of the bacteria, the lower the level of nutrient absorption. therefore this bacterium had to develop other mechanisms of nutrient and energy uptake
The survival mechanism of this bacterium is quite particular, first of all, it is an anaerobic bacterium, so it is found in sulfide-rich sediments. Its main feature is a liquid container inside called vacuole, which occupies 98% of its volume. In this vacuole, the nitrate that the bacteria use to oxidize sulfide is stored and thus obtain energy. <em>T. namibiensis</em> is unable to move, so they have to wait until the sea currents transport nitrate-rich seawater to store it in their vacuoles, so they can survive for up to 3 months without any other external substrate.
Answer:
c) The largest problem is that single viruses may create multiple plaques, resulting in overestimates of the number of viruses present.
Explanation:
- Plaque-based assays are the accepted method used for finding virus concentration in terms of infectious dose.
- Viral plaque assays determine the number of plaque forming units (pfu) in a virus sample, which is one measure of virus quantity.
