What variables should the scientists control in the experiment

Biology

1 answer:

Drupady [299]2 years ago

Answer:

It's important for a scientist to try to hold all variables constant except for the independent variable. If a control variable changes during an experiment, it may invalidate the correlation between the dependent and independent variable. When possible, control variables should be identified, measured, and recorded.

An enzyme that follows simple michaelis–menten kinetics has an initial reaction velocity of 10 μmol⋅min−1 when the substrate con

svet-max [94.6K]

The Vmax of the enzyme is 12 μmol⋅min−1

We use Michaelis-menten equation, which is given by;

$V=\frac{Vmax(S)}{Km+(S)} \\$

Where v is velocity of reaction

Vmax = maximum rate achieved by the system

[S] = concentration of a substrate

K $_{m}$ = Michaelis constant

Given V $_{0}$ = 10 $umolmin^{-1}$

[S] = 5km

Now, we calculate Vmax:

10 $umolmin^{-1}$ = $\frac{Vmax*(5Km)}{Km+5Km}$

Km = 1

$10=\frac{5KmVmax}{6Km}$

$\frac{10*6}{5} =Vmax$

$Vmax$ =12 μmol⋅min−1

5. Compare the energy emitted by waves with long wavelengths to waves with short wavelengths

irinina [24]

Explanation:

The energy emitted by long wavelength waves are smaller to those emitted by short wave lengths.

The energy of a wave is a function of its wavelength and frequency.

The wavelength of a wave is the distance between its crest.
Frequency is the amount of waves that passes through a point in a period of time.
Energy of a wave is directly proportional to frequency and inversely proportional to wavelength.
The higher the frequency of a wave, the more the energy.
Waves with a high wavelength carries very little energy.
Long wavelength radiations have a long wavelength as the name implies. They carry very little energy and have low frequency. Examples are infra-red.
Short wavelength radiations have short wavelength. They carry very high amount of energy and have very high frequency. Examples are x-rays and gamma rays.

Answer:

the child will either receive either an X or a Y chromosome from the father

Explanation:

The mother always give the child an X chromosome because thats the only one she can give

the father can either give an X or a Y which determines if the child will be female or male

What is the ultimate source of energy of almost any terrestrial (land) food chain or food web? What process converts this energy

andriy [413]

Hey there!

Here are your answers:

1. The proper answer to this question is "the Sun".

Reason:

The Sun is the ultimate source of energy for organisms it allows plants to use photosynthesis to convert light energy into energy for that organisms and other organisms.

Therefore the answer is the Sun.

Here is your second answer:

2. The proper answer to this question is "photosynthesis".

Reason:

Photosynthesis is the process that plants use to change (convert) light energy into energy (that other organisms can use). For example a apple tree uses photosynthesis to make apples for humans, and other organisms to consume for energy.

Therefore the answer is photosynthesis!

To sum up the answers are:
1.Sun
2.Photosynthesis

If you need anymore help feel free to ask me!

Hope this helps!
