The right answers are : Radiant energy and Conservation of energy.

Radiant energy, or radiative energy, is the only energy that can propagate in a vacuum, in the absence of matter. It is based on the principle of electromagnetic radiation, itself based on photon displacement. On a daily basis, radiant energy is very present; this is how the sun illuminates us.

-The energy of an isolated system can not be destroyed or created .

➥The energy is conserved, and can be transferred from one part of the system to another and / or change shape (heat, speed ...) .

➥Energy can also switch from one system to another.

Describe tissues and give an example of a tissue

Natalka [10]

Tissues are groups of cells that work together to form a specific function.

An example of a tissue is muscle tissue. There are three types of muscle tissue: cardiac, skeletal, and smooth.

These tissues are comprised of cells which work together to form a function - in the case of cardiac muscle tissue, these cells work together to keep the heart pumping blood (to keep it simple).

When exercising outside on an extremely warm day, the client can feel his heart pounding very rapidly. Thinking in terms of the

Nuetrik [128]

Answer:

A) Elastin

Explanation:

Elastin is the principle load-bearing protien present in the wall of aorta. It is the protien which coil and recoils like a spring within the elastic fibres and accounts for elasticity of blood vessels. As during excerise , afterload is increased ,thus a stretch is produced in the vessels. Similarly im warm environment the vessels dilate this this stretch is produced by elastin.

Allison and Heather are going to conduct an experiment to see whether salt affects the growth of plants. They gather five groups

SIZIF [17.4K]

Answer:

The dependant variable is the growth of the plants.

Explanation:

The independent variable is what changes the dependent variable.

for example, the type of salt concentration ( Independent variable ) is/ isn't going to change the growth ( dependant variable ) of the plant.

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.
