Which organelle stores the information that determines an individual blood type
Answer:organelle 1
Explanation:
Organulo 1 is the organelle that stores the information that determines an individual blood type. The correct option is option A.
What is organelle?A tiny cellular component known as an organelle serves a specialised purpose within a cell. The cytoplasm of prokaryotic and eukaryotic cells contains organelles. Organelles are frequently encased by a separate membrane in eukaryotic cells because they are more complicated.
Similar to the internal organs of the body, organelles are specialised and carry out important tasks required for proper cellular function. Organelles are responsible for a variety of tasks, such as powering a cell's energy needs and regulating its development and reproduction. Organulo 1 is the organelle that stores the information that determines an individual blood type.
Therefore, Organulo 1 is the organelle that stores the information that determines an individual blood type. The correct option is option A.

Your question is incomplete but most probably your full question was,
A child has a toy balloon with a volume of 1.75 liters. The temperature of the
balloon when it was filled was 21° C and the pressure was 1.00 atm. If the child
were to let go of the balloon and it rose 3 kilometers into the sky where the
pressure is 0.65 atm and the temperature is -10°C, what would the new volume
of the balloon be?
Answer:
2.41 Litres
Explanation:
Using the combined gas law equation as follows;
P1V1/T1 = P2V2/T2
Where;
P1 = initial pressure (atm)
P2 = final pressure (atm)
V1 = initial volume (L)
V2 = final volume (L)
T1 = initial temperature (K)
T2 = final temperature (K)
According to the information provided in this question;
P1 = 1 atm
P2 = 0.65 atm
V1 = 1.75 liters
V2 = ?
T1 = 21°C = 21 + 273 = 294 K
T2 = -10°C = -10 + 273 = 263 K
Using P1V1/T1 = P2V2/T2
1 × 1.75/294 = 0.65 × V2/263
1.75/294 = 0.65V2/263
Cross multiply
294 × 0.65V2 = 1.75 × 263
191.1 V2 = 460.25
V2 = 460.25 ÷ 191.1
V2 = 2.41 L

What is the wavelength of spectral line resulted from the electron transition from n=3 to n=2 in a hydrogen atom.
Answer:
[tex]\lambda=6.56x10^{-7}m[/tex]
Explanation:
Hello there!
In this case, it possible to use the Rydberg equation in order to calculate the wavelength for this transition from n=3 to n=2 as shown below:
[tex]\frac{1}{\lambda} =R_H(\frac{1}{n_f^2}-\frac{1}{n_i^2} )[/tex]
Thus, we plug in the corresponding energy levels and the Rydberg constant to obtain:
[tex]\frac{1}{\lambda} =10973731.6m^{-1}(\frac{1}{2^2}-\frac{1}{3^2} )\\\\\frac{1}{\lambda} =1524129.4m^{-1}\\\\\lambda=\frac{1}{1524129.4m^{-1}} \\\\\lambda=6.56x10^{-7}m[/tex]

The total pressure of all the gases inside a metal container is 9.8 atm. If the partial pressure of the oxygen in the container is 4.2 atm, what is the partial pressure of the rest of the gases in the container other than the oxygen?
5.6 atm is the partial pressure of the rest of the gases in the container other than the oxygen.
What is partial pressure?Each gas in a mixture adds to the overall pressure of a mixture. This portion represents the pressure. The pressure a gas would have if it were in its own volume and at its own temperature is known as the partial pressure. According to Dalton's law, the pressure distribution of an ideal gas mixture is equal to the combined partial pressures of the component gases.
The study of partial pressure is significant in the domains of physics, chemistry, and biology. The partial pressure of oxygen or carbon dioxide in the blood is used to calculate blood levels of each substance. The overall pressure in a container is equal to the sum of the partial pressures. The remaining gases must make up the remaining 5.6 atm if the oxygen partial pressure equals 4.2 atm and the sun reaches 9.8 atm in pressure.
Therefore, 5.6 atm is the partial pressure of the rest of the gases in the container other than the oxygen.

a) Write the word equation for the reaction of silver chlorate reacts with sodium phosphate to produce silver phosphate and sodium chlorate.
b) Write the balanced formula equation for this reaction.
c) If 287 g of silver chlorate reacts with 52.8 g of sodium phosphate, what is the maximum number of grams mass of silver phosphate will be produced?
d) Identify which reactant is the limiting reactant and which is the excess reactant.
e) How many grams of the excess reactant reacts and how many grams are left over?
Answer:
See Explanation
Explanation:
a) The word equation is;
silver chlorate + sodium phosphate ------> silver phosphate + sodium chlorate
b) The balanced reaction equation of the reaction is;
3AgClO3(aq) + Na3PO4(aq) ------->Ag3PO4(s) + 3NaClO3(aq)
c) amount of silver chlorate reacted = 287 g/191.319 g/mol = 1.5 moles
3 moles of silver chlorate yields 1 mole of silver phosphate
1.5 moles of silver chlorate yields 1.5 * 1/3 = 0.5 moles of silver phosphate
Amount of sodium phosphate reacted = 52.8 g/163.94 g/mol = 0.3 moles
1 mole of sodium phosphate yields 1 mole of silver phosphate
0.3 moles of sodium phosphate yields 0.3 moles of silver phosphate.
Hence the maximum number of grams mass of silver phosphate produced = 0.3 moles * 418.58 g/mol = 125.6 g
d) The excess reactant is silver chlorate while the limiting reactant is sodium phosphate
e) 3 moles of silver chlorate reacts with 1 mole of sodium phosphate
x moles of silver chlorate reacts with 0.3 moles of sodium phosphate
x = 3 * 0.3 = 0.9 moles of silver chlorate reacted
Mass of 0.9 moles of silver chlorate = 0.9 moles * 191.319 g/mol = 172 g of silver chlorate
Hence mass of silver chlorate left over = 287 g - 172 g = 115 g

Given the following data set, calculate the unknown quantity.
P= 1.23 mmHg atm, V=? kL, n= .773 mol, T= 152 °C
Answer:
V ≈ 16,662.63 L
Explanation:
The data given in the question includes;
The pressure in the medium, P = 1.23 mmHg
The number of moles of the substance present in the medium, n = 0.773 mol
The temperature of the substance in the medium, T = 152 °C = 425.15 K
The unknown quantity, V = The volume filled by the substance
The ideal gas law equation that can be used to find the unknown volume is given here as follows;
P × V = n × R × T
Where;
R = The Universal Gas Constant = 62.363 mmHg·L·mol⁻¹·K⁻¹
From the ideal gas law equation, we get;
V = n × R × T/P
Plugging in the values, gives;
V = 0.773 mol × 62.363 mmHg·L·mol⁻¹·K⁻¹ × 425.15 K/(1.23 mmHg) = 16,662.6305405 L
The volume occupied, which is the unknown quantity, V ≈ 16,662.63 L.

If I plant a green bean seed in the desert, will it grow thick, barrel-shaped stems full of water like a cactus? Why or why not?
Answer:
No, although the bean crop can grow perfectly in full sun or a little shade in very warm places. It does not mean that they will adopt the growth patterns of the cactus, especially because this plant needs constant watering (in small quantities), very constant. Beans require good drainage for their growth.
Each vegetation have its own characteristics and the power of adaptation. A green bean cannot survive in a desert like a cactus in desert without water. It can only grow thick in soil with proper water content and nutrients.
What is cactus?Cactus is a type of plant grow in dry regions such as deserts. It can adapt in deserts without water for long time because, the plant have enough water storage in its stem.
Domestic vegetation such as bean, pea, nuts etc ill not grow in dry regions because they cannot adapt in deserts without water. The soil in deserts is dry and have no nutrients.
These conditions prevent the growth of vegetables in desert areas. Moreover, desert have summer season only. The extreme temperature over there will cause the normal plants to diminish.
Therefore, planting green bean in deserts will not make it grow thick like a cactus plant.
