Answer:
Option #2 (Green seeds)
Explanation:
Since both the plants are true-breeding, both plants only have the green allele. Therefore, their offspring must also only have the green allele and will therefore have green seeds.

A gas has a volume of 250.0 liters at 17.0 °C and 3.00 atm of pressure. what volume must the gas be increased for the gas to be at STP conditions?
Answer:
0.706 L (Liters)
Explanation:
P1V1 = P2 V2 3 atm 250.0 mL = 1 atm X
T1 T2 290 K 273 K
706 mL = X
According to the question,
Pressure,
Initial, [tex]P_1 = 3 \ atm[/tex]Final, [tex]P_2 = 1 \ atm[/tex]Temperature,
Initial, [tex]T_1 = 17^{\circ} C[/tex] or, [tex]290 \ K[/tex]Final, [tex]T_2 = 273 \ K[/tex]Volume,
Initial, [tex]V_1 = 250 \ L[/tex]Final, [tex]V_2 = \ ?[/tex]By using the Boyl's and Charl's combination law, we get
→ [tex]\frac{P_1 V_1}{T_1} = \frac{P_2 V_2}{T_2}[/tex]
or,
→ [tex]V_2 = \frac{P_1 V_1 T_2}{T_1 P_2}[/tex]
By putting the values, we get
→ [tex]= \frac{3\times 250\times 273}{290\times 1}[/tex]
→ [tex]= 706 \ L[/tex]
Thus the aforementioned answer is right.

Subscript basically tells you the number of element or ions present in a compound. In this case the subscript of carbon which is 3 denotes that only three carbon atoms is present in the compound.
DESCRIBE the five types of chemical reactions
(Synthesis, Decomposition, Single displacement, Double displacement, Combustion)
The study of chemicals is called chemistry.
When two elements react together to form a new compound is called a reaction.
When two-element join together to form a new compound is called synthesis.
[tex]C + O_2 --> Co_2[/tex]
The breakdown of a compound into two different elements is called decomposition.[tex]H_20 ----> H_2 + O_2[/tex]
The substitute of one element in the compound is called single displacement.[tex]Fe + H_2So_4---> FeSo_4+ H_2[/tex]
The substitute of two-element in the compound is called double displacement.[tex]BaCl + H_2So_4 + ---> BaSo_4 + HCl[/tex]
The burning of the element in the presence of oxygen is called a combustion reaction.[tex]C + O_2 ---> CO_2[/tex]

How many molecules of carbon dioxide are in 12.2 L of the gas at STP?
Answer:
Converting Between Moles and Liters of a Gas at STP. To convert between moles and the volume of a gas at STP, we will use the factor label method discussed in the first unit. This conversions relies on the fact that a mole of gas at STP has a volume of 22.4 L.
Explanation:
One molecule of carbon dioxide at STP has a volume of 22.4 liters . Thus number of molecules of carbon dioxide in 12.2 L is 3.27 × 10²³ molecules.
What is one molecule?A molecule is formed by the combination of same or different kinds of atoms. A number molecules together form a compound. Water, carbon dioxide etc. are compounds.
One mole of a molecule contains 6.022 × 10²³ number of atoms. Similarly, one mole of a compound contains, 6.022 × 10²³ number of molecules.This number is called Avogadro number.
At standard temperature and pressure (STP) that is at 298 K and 1 atm pressure, one mole of any substance carry 22.4 L. Thus number moles of 12.2 L of carbon dioxide is 12.2 / 22.4 = 0.54 moles.
Number of molecules = 0.54 moles × 6.022 × 10²³
= 3.27 × 10²³
Hence, number of molecules of carbon dioxide in 12.2 L is 3.27 × 10²³ molecules.

Explanation:
Substance X has a specific heat capacity that is twice as large as Substance Y. If both samples ended up at the same change in temperature from the same amount of energy added, what is the relationship between the masses of the two samples? Explain.
Answer:
Substance X has a smaller mass
Explanation:
The relationship between the mass of the two samples is that the mass of X is smaller compared to the mass of Y.
The specific heat capacity is given as:
C = [tex]\frac{H}{m x change in temperature}[/tex]
We can see that the higher the specific heat capacity the lesser the mass or simply put, the specific heat capacity of a body is inversely related to its mass.
If the amount of heat is constant i.e the same and the specific heat capacity of X is twice that of Y, then substance X has a smaller mass

The best solution to deforestation is to curb the felling of trees by enforcing a series of rules and laws to govern it. Deforestation in the current scenario may have reduced; however, it would be too early to assume. The money-churner nature of forest resources can be tempting enough for deforestation to continue.

Answer:
Pseudoscience
Explanation:
Predicting the future based solely on the position of the planets is an example of pseudoscience.
Pseudoscience is a body of knowledge that is not based on the scientific method but on some unverifiable/unprovable claims.
Predictions about the future can only be valid if it is based on the scientific method, not just about the position of the planet. The scientific method involves observation, hypothesis formulation, testing of the hypothesis through repeatable experiments, and arriving at conclusion.
Any other statement or belief that is not based on these procedures is said to be pseudoscientific.

What colors are absorbed Best Buy the plant gizmo
Answer:
Yellow and Green
Explanation:
It is not blue the graph shows is isnt blue so the colors that absorbed the worse were green and yellow
Blue and red are the colors that plants can absorb the most. The pigments used for photosynthetic processes, such as chlorophyll in plant cells' chloroplasts, are what absorb particular visible-spectrum light wavelengths.
The energy of specific light wavelengths is absorbed by special pigments in chloroplasts of plant cells, resulting in a chemical chain reaction that is known as the light-dependent process of photosynthesis. The best visible light wavelengths for photosynthesis are in the blue (425–450 nm) and red (600–700 nm) ranges.
Chlorophylls do not absorb light at green and yellow wavelengths, as shown by the extremely low level of light absorption between 500 and 600 nm.
