What is the main function of the part labeled Yin the model?
Answer:
The part labelled Y is the chloroplast and its main function is to produce food for the plant in the reactions of photosynthesis.
Explanation:
Plants are autotrophic organisms in that they are able to manufacture their own food. Plants are able to manufacture their own food due to the presence of the cell organelle known as the chloroplast. The plant chloroplast has its own DNA and can reproduce independently, from the rest of the cell. They can as well produce amino acids and lipids required for the chloroplast membrane.
Chloroplasts are green-colored membrane-bound organelles found within the plant cell. Their green color is due to the presence of the pigment, chlorophyll. Chlorophyll in the chloroplasts are responsible for absorbing light energy from sunlight and using this absorbed energy to make simple sugars (carbohydrates) from carbon (iv) oxide and water. This is the main function of the chloroplasts in plant cells.
Photosynthesis occurs in the chloroplasts in two reaction steps:
1. The light reaction - involves the splitting of e=water molecules using the energy of sunlight
2. The dark reactions - carbon (iv) oxide from the air is used to produce sugars.

The value of Kp for the reaction 2 A(g) + B(g) + 3 C(g) → 2 D(g) + E(g) is 18530 at a particular temperature. What would be the value of Kp for the reaction 2 D(g) + E(g) → 2 A(g) + B(g) + 3 C(g)?
Answer:
[tex]Kp2=5.3967x10^{-5}[/tex]
Explanation:
Hello there!
In this case, since the Kp for the first reaction is given, according to the following equilibrium expression:
[tex]Kp=\frac{p_D^2p_E}{p_A^2p_Bp_C^3} =18530[/tex]
However, since the second reaction stands for the reverse of the initial one, the equilibrium expression would be:
[tex]Kp_2=Kp=\frac{p_A^2p_Bp_C^3}{p_D^2p_E}[/tex]
And therefore its Kp the inverse of the aforementioned one:
[tex]Kp2=1/18530\\\\Kp2=5.3967x10^{-5}[/tex]

Answer:
i think it's Organization
Explanation:
The reason being is because they obviously said 'humans' so that's why i think it is Organization
Scientists group similar organisms together through the process called classification. Each similar groups is classified into different organizations.
What is biological classification?The arrangement of species into groups according to significant similarities is known as biological classification. Then, these groups are broken down into more focused, smaller subgroups. Additional details on the species that make up each subgroup are provided.
Organisms are categorized by scientists to make them simpler to research and to facilitate information sharing. Before biologists properly comprehended genetics, the study of biological classification was conducted.
At first, scientists simply categorized creatures based on their outward appearance. Later, as genetic research developed, classification of organisms was based on the genetic and evolutionary links between them.
Therefore, scientists classify each organisms to suitable organizations.

Which is the correct number of moles of nitrogen monoxide that is produced from 13.2 moles of oxygen gas in the presence of excess ammonia (NH3)?
Answer:
10.56 moles of NO will be produced
Explanation:
The balanced reaction of ammonia, NH₃ with oxygen, O₂ is:
4NH₃ + 5O₂ → 4NO + 6H₂O
Where 5 moles of oxygen react with an excess of ammonia to produce 4 moles of nitrogen monoxude.
If 13.2 moles of O₂ react:
13.2 mol O₂ * (4 mol NO / 5 mol O₂) =
10.56 moles of NO will be producedOrganisms are classified into different kingdoms based on?...

What is the density of a book with a mass of 60g and a volume of 20 cm3? *
Answer:
[tex]3 g/cm^{3}[/tex]
Explanation:
Density is a measure of a substance's mass over its volume.
d = m/v
Therefore d = 60g/20cm3 = 3 g/cm3
If you have 12 atoms of hydrogen before a chemical reaction, how many atoms of hydrogen will be present
Answer:
12 atoms of hydrogen will be present in the product
Explanation:
12 atoms of hydrogen will be present in the product because the law of conservation of mass states that mass is neither created nor destroyed in chemical reactions.
The law of conservation states that the mass of the element remains the same during the course of the reaction.
The law of reaction conformed by the following:-
Mass of reactant Mass of productAccording to the question, the amount of hydrogen is 12 atoms in the reactant and the amount will remain the same at the end of the reaction, which is a product that is 12 atoms
Hence, the amount remains the same in the reaction that is 12 atoms

1. Using the structural formulas for ammonia (NH3 on the left) and hexane (C6H14 on the right) below which statement explains what will happen when ammonia and hexane are mixed?
A. Hexane will dissolve with ammonia if you stir them together for 10 minutes
B. Ammonia and hexane will not dissolve because one molecule is polar and the other is non polar.
C. Ammonia and hexane will dissolve together
D. Ammonia and hexane will not dissolve because one molecule is ionic and the other is non polar
2. If you add water to 750.0 mL of a 2.800 M KCl solution, and its molarity changes to 1.500 M, what will the new volume be?
1200 mL
401.0 mL
1400 mL
800.0 mL
Answer:
1. B. Ammonia and hexane will not dissolve because one molecule is polar and the other is non polar.
2. 1400 mL
Explanation:
In chemistry, like dissolve like! Ammonia is a polar molecule having a significant dipole moment owing to its three N-H bonds. On the other hand, hexane is a purely non-polar hydrocarbon hence the two substances can never dissolve in each other.
From the dilution formula;
C1V1=C2V2
C1= Initial concentration of the solution
V1 = Initial volume of the solution
C2 = Final concentration of the solution
V2= Final volume of the solution
2.8 M * 750.0 mL = 1.5 M * V2
V2 = 2.8 M * 750.0 mL/1.5 M
V2 = 1400 mL

If you are given 608 grams of calcium phosphate Ca3(PO4)2, how many moles would you have? *
Answer:
You would have 1.96 moles.
Explanation:
You are given 608 grams of calcium phosphate Ca₃(PO₄)₂.
Molar mass (M) is the amount of mass that a substance contains in one mole. This substance can be an element or a compound.
Since the molar mass of the compound Ca₃(PO₄)₂ is 310 g / mole, and taking into account the definition of molar mass, you can apply the following rule of three: if 310 grams of Ca₃(PO₄)₂ are contained in 1 mole, 608 grams of the compound in how many moles are present?
[tex]moles=\frac{608 grams* 1 mole}{310 grams}[/tex]
moles= 1.96
You would have 1.96 moles.

Answer:
Ecosystem is food web of primary and secondary producers and consumers.
Explanation:
In an ecosystem, there exist primary producers, primary consumers, secondary consumers, and tertiary consumers such as detritivorous such as viruses and bacteria that act on the living bodies and recycle the nutrients back to plants through the soil. The primary producers such as all green plants and others make their own food being autotrophs they use sunlight and carry out photosynthesis process. On the depend on the herbivorous they eat grass etc. The secondary consumers are carnivores as heterotrophs that feed on herbivores.What two gases are cycled through ecosystems?

Identify at least four limiting factors in the local ecosystem and their impact on native populations.
4 limiting factors could be water, space, pollution, and access to mates, could all be factors in limiting the native population. Water, could be affected by pollution, and this would remove water, which means that no living things would be able to survive, or at the best be hindered in its growth. Space could be removed by deforestation, or simple water rising, and this could kill off the population, thus removing mates for the population. (hope this helped, if it did, please consider marking brainiest)
The availability of food, water, shelter and diseases are the four limiting factors in the local ecosystem and their impact on native populations.
What are the limiting factors?The limiting factors such as availability of food, water, shelter and diseases can change animal and plant populations because these factors has a direct impact on the organisms and the organisms is depend on these factors for their survival.
So we can conclude that availability of food, water, shelter and diseases are the four limiting factors in the local ecosystem and their impact on native populations.
