Those molecules that we can glean information about their position via concentration gradient are called morphogens.

<h3>What is concentration gradient?</h3>

The term concentration gradient refers to the difference in the amount of substance on two different sides. This gradient could be used to glean useful information about the molecule position.

Chemical molecules that impart positional information through their concentration gradient are called morphogens.

Chemical molecules that impart positional information through their concentration gradient are called morphogens.

What are morphogens?

In cells of living organisms, positional information are transported through changes in the concentration gradient of morphogens.

The presence of morphogens in a tissue helps to monitor the pattern of development of that tissue.

This chemical molecule embryology because it imparts the positional information of an embryo resulting to cells differentiating at specific positions.

The density of copper is 8.94 g/cm3. An irregular shaped sample of metal is 14 g and displaces a volume of 2.98 mL. (a) Find the

Vedmedyk [2.9K]

Explanation:

The density of a substance can be found by using the formula

$density = \frac{mass}{volume} \\$

From the question

mass of metal = 14 g

volume = 2.98 mL = 2.98 cm³

It's density is

$density = \frac{14}{2.98} \\ = 4.69798657...$

We have the answer as

4.70 g/cm³

The metal is not copper since it's density is less than that of copper.

Hope this helps you

Each glucose molecule consists only of carbon, hydrogen, and oxygen atoms. If each molecule contains 53.3% oxygen and 6.7% hydro

MAVERICK [17]

53.3% + 6.7% = 60%, 100% - 60% = 40%. 40% of glucose is made of carbon. Since there are only three types of atoms in glucose, and the amount of hydrogen and oxygen is already given, this means that whatever percentage is left (40%) has to be carbon.

A mixture of gases with a pressure of 800.0 mm hg contains 60% nitrogen and 40% oxygen by volume. what is the partial pressure o

klasskru [66]

Hello!

<span>We have the following statement data:
</span>
Data:
$P_{Total} = 800 mmHg$
$P\% N_{2} = 60\%$
$P\% O_{2} = 40\%$
$P_{partial} = ? (mmHg)$

<span>As the percentage is the mole fraction multiplied by 100:

</span> $P = X_{ O_{2} }*100$

<span>The mole fraction will be the percentage divided by 100, thus:
</span><span>What is the partial pressure of oxygen in this mixture?
</span>
$X_{ O_{2} } = \frac{P}{100}$
$X_{ O_{2}} = \frac{40}{100}$
$\boxed{X_{ O_{2}} = 0.4}$

<span>To calculate the partial pressure of the oxygen gas, it is enough to use the formula that involves the pressures (total and partial) and the fraction in quantity of matter:
</span>
In relation to $O_{2}$ :

$\frac{P O_{2} }{P_{total}} = X_O_{2}$
$\frac{P O_{2} }{800} = 0.4$
$P_O_{2} = 0.4*800$
$\boxed{\boxed{P_O_{2} = 320\:mmHg}}\end{array}}\qquad\quad\checkmark$
