Answer:
Photosythesis is the process of which plants make oxygen and also gulcose. This process happens when the plants uses their roots to taken in water in the ground and also anchor themselves in the ground. The stomata in the leaves take in carbon dioxide and the sunlight and using theses materials the plants create glucose and oxygen we breath.
You have an Elodea sprig in a test tube containing bromothymol blue. Then you watch it for several days. At what time of day will the oxygen level in the tube be the lowest?
a)just before sunset
b)midnight
c)just before sunrise
d)mid-afternoon
Answer:
c
Explanation:
If you put an Elodea plant in a test tube containing bromothymol blue and watch the oxygen level, the time of the day in which the oxygen level in the tube would be lowest will be just before sunrise.
First, there is a need to understand oxygen is produced as a result of photosynthesis according to the following equation:
[tex]6CO_2 + 6H_2O ---> C_6H_1_2O_6 + 6O_2[/tex]
The process of photosynthesis takes place in 2 reactions:
Light-dependentLight-independentOxygen is produced from the splitting of water in the light-dependent reaction. Hence, the production of oxygen stops when there is no light - when the sun sets.
Whatever quantity of oxygen that has been produced just before the sun sets would remain and will gradually be used for respiration by the Elodea plant until the sun rises again the following day.
Thus, the level of oxygen in the tube would usually be lowest just before the sun rises and oxygen can be produced again.

Which is FALSE? First exclude the four correct answers. Which is FALSE? First exclude the four correct answers. The leaves are only a small part of the plant and must produce enough energy-rich sugars to support all non-green parts like roots or flowers. Only when overall photosynthetic activity is greater than overall respiration activity of the whole plant can the plant accumulate biomass and grow. Sugar produced in photosynthesis must support the plant’s energy needs both day and night. Leaves perform more photosynthesis than respiration because they don’t have mitochondria. In trees that drop their leaves over the winter, some sugar produced in one year is stored in stems or roots and fuels the production of new leaves in the next year.
Answer:
1 .The leaves are only a small part of the plant and must produce enough energy-rich sugars to support all non-green parts like roots or flowers --TRUE.
2.Only when overall photosynthetic activity is greater than overall respiration activity of the whole plant can the plant accumulate biomass and grow--TRUE.
3.Sugar produced in photosynthesis must support the plant’s energy needs both day and night TRUE.
4. In trees that drop their leaves over the winter, some sugar produced in one year is stored in stems or roots and fuels the production of new leaves in the next year TRUE.
The statement that is FALSE is
Leaves perform more photosynthesis than respiration because they don’t have mitochondria.
Explanation:
The statement that is FALSE is
Leaves perform more photosynthesis than respiration because they don’t have mitochondria and it is false because leaves contain both mitochondria and chloroplast.
The plants leaves have chloroplast, an organelles that house the chlorophyll which help its to photosynthesized. Plants also require ATP to carry out cellular activities and need oxygen to breakdown sugars produced from photosynthesis to produce ATP, because of this, they need mitochondria to achieve this and that is why they have mitochondria.
In the night, when there is no sunlight, plants perform respiration, they use oxygen to break the sugars they produced in order to produce ATP.

Answer:
a) Simplification
b) Disjunctive syllogism
c) Modus ponens
d) Addition
Explanation:
Simplification (also known as conjunction elimination) is an immediate argument form by which is inferred, for example, that if the conjunction A and B is true, then consequently A must be true, and B also must be true. Modus ponens means in Latin "mode that by affirming affirms", this being a mode of deductive reasoning and a rule of inference. A hypothetical syllogism is a valid argumentation mode in which a syllogism, i.e., deductive reasoning that arrives at a specific conclusion by analyzing two different premises, may have a conditional statement for one or both of these premises. A hypothetical syllogism is associated with modus ponens in the way that sometimes it is considered to be a double modus ponens. Addition is a rule of inference that enables the introduction of disjunctions into logical proofs. For example, the rule of addition states that if P is true, then consequently P or Q must be true.

What are Earth's resources?The Earth's resources are referred to as natural resources that are useful raw materials for the manufacturing and production of goods. They occur naturally, meaning that man cannot make them but instead use and modify the resources in ways that are beneficial. Examples include air, water, soil, minerals, fuels, plants, and animals.
Natural resources are not finite but by human activities, such earth's resources become poisonous day by day for our health such as air, water, and soil. So, it's time to beware and spread the message to affect earth's resources positively.
Therefore, the way by which people positively affect the earth's resources is to build dams, use cars that emit fewer harmful gases, and hat the runoff of factory waste into rivers and streams.

What happens when ionic compounds dissolve in water?
a) Cations and anions are released into the solution
b) They split up H2O molecules into H and O
c) They stick to the wall of the beaker
d) They are transformed into non-metals
Taking into account the definition of ionic compound, the correct answer is option a): Cations and anions are released into the solution.
First, you have to know that an ion is an electrically charged particle.
Ionic bondSo, the ionic bond consists of the electrostatic attraction between ions with charges of opposite sign. This type of bond occurs between the chemical combination of a metal and a nonmetal.
Ionic compoundFinally, an ionic compound is made up of positive and negative ions, held together by electrostatic forces of attraction. Atoms of metallic elements tend to lose one or more electrons when combined with non-metallic atoms, and non-metallic atoms tend to gain one or more electrons.
As a result of this transfer of electrons, the metallic atom becomes a positive ion (called a cation) and the non-metallic atom becomes a negative ion (called an anion).
In other words, an ionic compound is a chemical compound made up of two substances with a significant difference in their electronegativities. It is formed preferably between metals and non-metals.
Ionic compounds dissolve in waterSo when ionic compounds dissolve in water, they separate into cations and anions, electrolytic dissociation occurs. This is because water becomes a conductor of electricity.
In summary, the correct answer is option a): Cations and anions are released into the solution.

How is cell differentiation different than mitosis?
Cell differentiation does not cause proliferation.
Cell differentiation produces cells with different gene expressions.
Cell differentiation only occurs after a wound.
Cell differentiation produces cells with different DNA.
Answer:
it should be produces cells with different gene expressions
The process of cell differentiation is different than mitosis by the mechanism that cell differentiation produces cells with different gene expressions. Thus, the correct option for this question is B.
What is Mitosis?Mitosis may be defined as a type of cell division that produces two genetically identical daughter cells from a parental cell. It generally synthesizes diploid daughter cells. This process of mitosis occurs in the eukaryotic cells.
The generation of specialized cell types is called cell differentiation. It is the process during which a cell ceases to divide and develops specialized structural elements and distinct functional properties due to different gene expressions.
After the termination of cell differentiation, cells are structurally and functionally specialized with respect to their functions.
Therefore, the process of cell differentiation produces cells with different gene expressions. Thus, the correct option for this question is B.

What happens to the temperature of the water when it begins to melt?
Answer:
When you heat ice, its temperature rises, but as soon as the ice starts to melt, the temperature stays constant until all the ice has melted.
According to the graph, the temperature of the water continues to increase during the change of state. Thus, the correct option for this question is A.
What will happen if the ice melts?When the ice melts, the level of seawater would tend to be increased. This is because solid ice has tended to change its state to liquid. And now liquid may increase the density of the seawater which ultimately rises its level.
It is noted that when the temperature reaches that 0°C. For some instances of time, it will remain the same, but as time passes it tends to increase. The same principle is seen when the temperature reaches 100°C. So, it can not be said that the temperature remains at 0°C or 100°C until the changes in state.
Therefore, the temperature of the water continues to increase during the change of state. Thus, the correct option for this question is A.
