Answer:

Respiration (breathing) is the way your body gets oxygen into the lungs from the air outside. Cellular respiration describes how your cells make ATP - a molecule used to provide energy for chemical reactions.

Which situation results from increased biodiversity in an ecosystem

Nastasia [14]

The correct answer is - increased competition.

If an ecosystem experiences an increase in its biodiversity, than the result of it would be increased competition. The increased competition will be for food sources, water sources, territory. The reason why increased competition will occur is that there are only limited mounts of food sources, water sources, and territory in the ecosystem. There's also certain amount of niches in the ecosystem, and once all of them are occupied by some species, any other that is specialized for that niche will be competitor plus. This increased competition will lead to high evolutionary pressure, which will result in relatively quick adaptations and specialization in order to survive.

Luba_88 [7]

Answer:

The answers are:

1. initial composition of microbial community (controlled variable)

2. age of the mice (controlled variable)

3. change in body fat (dependent variable)

4. diet (independent variable)

5. weight gain (dependent variable)

6. final composition of the microbial community (controlled variable)

Explanation:

Before I go ahead to explain each of the choices of classification, let us define each of the different types of variable.

1. Independent variable: this is a variable that is under the control of the experimenter. It is made up of the factors that are being tested. In our example, the independent variables is; diet. The aim of the experiment is to study the effect of the type of diet on the mice. The diet can also be varied and assigned at will by the experiment.

2. Dependent variable: a dependent variable is one whose outcome is reliant on the effect of the changes in the independent variable. It is the factor to be measured. In our example, the factors that obey these definitions are; change in body fat and weight gain. these two factors depend on the types of diet taken by the mice, hence they are the factors to be measured.

3. Controlled variable: these are variables that are kept constant throughout the experiment to rule out biases, because they produce the same effect on the dependent variable as the independent variable and must be keep constant or uniform in the test groups. in our example, the factors that are controlled include; initial and final compositions of the microbial communities and the age of the mice, because the microbial composition if not uniform among the groups can cause biases in how the diets are processed, and the age of the mice also must be uniform to avoid age-related differences in the processing of the diets

The kinetics analyses of an enzyme are measured as a function of substrate concentration in the presence and in the absence of 2

Aleksandr-060686 [28]

Answer:

take the reciprocal of the values as 1/S and 1/V and plot the values on lineweaver-burk plot.

so the re-arranged data is as following

1/S 1/V (no inhibitor) 1/V (with inhibitor)

0.333 0.096 0.244

0.2 0.068 0.156

0.1 0.044 0.088

0.033 0.029 0.044

0.011 0.024 0.029

and the plotted lineweaver-burk plot with the equation of straight line would be....

where, first line represents the velocity of reaction with no inhibitor and second line represent the velocity in presence of inhibitor. X-axis has the substrate concentration as 1/S and y-axis has the velocity as 1/V.

as per the plot, equation of line on the lineweaver-burk plot, Y = mx + c, where c = 1/Vmax and m = Km/Vmax.

so solve for the given equations.

First, equation of line in the absence of inhibitor is Y = 0.23x + 0.021

so Vmax = 1/0.021 = 47.6 micromol/min

and Km/Vmax = 0.23, or Km = 0.23 x 47.6

Km = 10.95

Km do not have a unit, so 10.95 x 10-6 or as per your values round it up to 1 decimal point as 1.1 x 10-5

so value of Vmax = 47.6micromol/min and Km = 1.1 x 10-5 in the absence of inhibitor.

similarly, equation of line in the presence of inhibitor is given as Y = 0.67x + 0.021

so Vmax = 1/0.021 = 47.6 micromol/min

and Km/Vmax = 0.67

or Km = 0.67 x Vmax = 0.67 x 47.6 = 31.89

Km do not have a unit, so 31.89 x 10-6 or 3.1 x 10-5

so value of Vmax = 47.6micromol/min and Km = 3.1 x 10-5 in the absence of inhibitor.
