B.) Plant adaptations are changes that help a plant species survive in its environment. Aquatic plants that live underwater have leaves with large air pockets inside that allow the plant to absorb oxygen from the water. The leaves of aquatic plants are also very soft to allow the plant to move with the waves.
*I literally just took it today I know the answer B is correct. (Broad leaves that float)

How many moles of Fe2O3 can be made from 50 moles of Fe?
Answer: Synthesis
0.84 moles of oxygen
25 moles of [tex]Fe_2O_3[/tex]
Explanation:
The balanced chemical equation is:
[tex]4Fe+3O_2\rightarrow 2Fe_2O_3[/tex]
This is a synthesis reaction as one product is formed by combination of two reactants.
According to stoichiometry :
a. 2 moles of [tex]Fe_2O_3[/tex] require = 3 moles of [tex]O_2[/tex]
Thus 0.56 moles of [tex]Fe_2O_3[/tex] require=[tex]\frac{3}{2}\times 0.56=0.84moles[/tex] of [tex]O_2[/tex]
b. 4 moles of [tex]Fe[/tex] give = 2 moles of [tex]Fe_2O_3[/tex]
Thus 50 moles of [tex]Fe[/tex] give =[tex]\frac{2}{4}\times 50=25moles[/tex] of [tex]Fe_2O_3[/tex]

Conclusion:
Your conclusion will include a summary of your lab results and an interpretation of the results. Please write in complete sentences.
1. List one-way mitosis and meiosis are the same and one way they are different.
Meiosis has 2 cell divisions, but mitosis has just one cell division. Since the parent cell develops diploid cells, meiosis I is the same as mitosis. The distinction between meiosis and mitosis is that after the whole process, meiosis produces genetically distinct haploid daughter cells, while mitosis produces genetically identical diploid daughter cells.
2. What is one advantage and one disadvantage of sexual reproduction?
The greatest benefit of sexual reproduction is that it aids in the development of offspring that are well suited to environmental environments due to genetic differentiation. As a result, the nation has a diverse range of descendants. The downside is that it needs two parents and takes longer than asexual reproduction.
3. What is one advantage and one disadvantage of asexual reproduction?
Asexual reproduction has the advantage of requiring only one parent, taking a short amount of time, and producing genetically identical offspring. The only drawback is that when there is a catastrophe, the mortality rate is poor due to the generation of genetically identical offspring.
4. Some living organisms are capable of both asexual and sexual reproduction. Explain how this can be an advantage.
To produce offspring, the organism may use either sexual or asexual reproduction. If it is difficult to find a mate, the living being will use asexual reproduction to produce offspring quickly. Sexual reproduction is possible because the individual requires genetically distinct offspring for survival.

List one way mitosis and meiosis are the same and one way they are different.
Meiosis has 2 cell divisions, but mitosis has just one process. Since the parent cell develops diploid cells, meiosis I is identical/ same as mitosis. The excellence between meiosis and mitosis is that after the complete process, meiosis produces genetically distinct haploid daughter cells, while mitosis produces genetically identical diploid daughter cells.
What is one advantage and one disadvantage of sexual reproduction?
Sexual reproduction is more efficient in its process of removing harmful mutations from the population. Although there will be offspring who don't survive due to the birth defects they encounter, it is a plus that protects the future of that species.
What is one advantage and one disadvantage of asexual reproduction?
A bad mutation can make asexually, produced organisms prone to disease and might destroy large numbers of offspring. Some methods of agamogenesis produce offspring that are close and compete for food and space.
Some living organisms are capable of both asexual and sexual reproduction. Explain how this can be an advantage.
An organism has many benefits for having the flexibility to breed both sexually and asexually. The primary of those benefits is that it doesn't need to find a mate so as to breed, so it can create offspring by itself, and enable the continuation of its species.

How much momentum does a 200 kg rhino have that is running at 35 m/s E
Answer:
7000 kg*m/s E
Explanation:
Momentum formula: p=mv
m=200kg
v=35 m/s East
p=(200kg)(35m/s E)
m=7000 kg*m/s E
If you want to simplify it further, m=7*10^3 kg*m/s E
Answer:
[tex]\boxed {\boxed {\sf 7000 \ kg*m/s \ E}}[/tex]
Explanation:
Momentum is the product of mass and velocity.
[tex]p=m*v[/tex]
The mass is 200 kilograms and the velocity is 35 meters per second east.
[tex]m= 200 \ kg \\v= 35 \ m/s \ E[/tex]
Substitute the values into the formula.
[tex]p= 200 \ kg * 35 \ m/s \ E[/tex]
Multiply.
[tex]p= 7000 \ kg * m/s \ E[/tex]
The rhino has 7000 kg*m/s E of momentum.

A container of nitrogen gashas a pressure of 256.4mm Hg at 362K. If the temperature is decreased to 251K, what is the pressure of the gas in the container?Circle the Correct Answer: (106mmHg or 178mmHg)
According to Reference Table G, how does a
decrease in temperature from 40°C to 20°C affect
the solubility of NH3 and KCl?
A) The solubility of NH3 increases, and the
solubility of KCl increases.
B) The solubility of NH3 increases, and the
solubility of KCl decreases.
C) The solubility of NH3 decreases, and the
solubility of KCl increases.
D) The solubility of NH3 decreases, and the
solubility of KCl decreases.
Answer:
A) The solubility of NH3 increases, and the
solubility of KCl increases.
Explanation:
The solubility of ammonia and potassium chloride increases with decrease in temperature from 40°C to 20°C.
What is solubility?Solubility is defined as the ability of a substance which is basically solute to form a solution with another substance. There is an extent to which a substance is soluble in a particular solvent. This is generally measured as the concentration of a solute present in a saturated solution.
The solubility mainly depends on the composition of solute and solvent ,its pH and presence of other dissolved substance. It is also dependent on temperature and pressure which is maintained.Concept of solubility is not valid for chemical reactions which are irreversible. The dependency of solubility on various factors is due to interactions between the particles, molecule or ions.

Newton's Third Law of Motion: "For every action there is an equal and opposite reaction." What is a force pair? Are they easy to identify?
Answer:
A force pair is a couple of forces which are acting on any given body from opposite directions called action-reaction forces.
One can simply identify the force pair by identifying two objects which are interacting and by describing who is pushing whom and by identification of their drawing.
A book resting on table has two participants, a book applying force downwards due to gravity and the table pushing it away from the earth surface. These are action and reaction forces.

Explain why the size of solid particles and the temperature of reaction affects the reaction rate according to the collision theory in other words explain why a reaction speed up or slow down based on interactions between reactive molecules when temperature of the reaction or size of solid reacting particles changed
Answer:
Increasing the surface area of a reactant increases the frequency of collisions and increases the reaction rate. Several smaller particles have more surface area than one large particle. The more surface area that is available for particles to collide, the faster the reaction will occur.Feb 22, 2021
