Answer:
<u>All the substrates are bound to the enzyme</u>, thats why the reaction rate stopped increasing.
Explanation:
Actually an enzyme works by binding a substrate molecule to its active site, producing a product , resulting in an increase in the rate of reaction.
Enzyme + substrate = Enzyme + product
Whenever enzymes are added , reaction rate increases as the substrates are being bound to the enzyme's active sites but then occurs a stage where further addition of enzyme cannot increase the reaction rate because all the substrates have bound to the enzyme and <u>there are no substrates left.</u> Hence the reaction rate stopped increasing.

See the answer below
Explanation:
<em>It may seem that the options have been omitted in this question. However, in order to evaluate the claim that a mean from a particular group is statistically higher or lower to a mean from another group, there would be a need to compare the two means. </em>
Mean comparison or testing for a significant difference between means can be carried out using the Student's t-test or one-way Analysis of Variance (ANOVA).
When the means being compared are just for 2 groups as indicated in the illustration, Student's t-test and one-way ANOVA can be used. However, once there are more than 2 group means being compared, one-way ANOVA will only be applicable.

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.
