Two tubes A & B were set up as shown above. Both tubes were left indoors for 50 minutes and then taken outdoors for another 50 minutes. The tubes were weighed every 10 minutes. The table shows the results obtained.
Answer:
Explanation:
Question A
Evaporation happens because fast moving molecules break out of the surface of the water. The fact that there is part of a plant in the water means that the water travels up to the leaves where it evaporates. There are two sources of evaporation in test tube A and only one in B.
Question B
The Cotton plug in the top of the test tubes slows the process down. There are still molecules that are escaping but the cotton absorbs them especially in test tube B. The molecules are free to go in test tube A. They make their way to the leaves where they evaporate.
Part C
You'll have to do the rest of this yourself. The graph for Test Tube A should be less (closer to the x axis) than B.
The rest of the answers are explained in A and B

The diagram shows a swinging pendulum.
A pendulum hanging from a bar is shown in 3 positions. 1 is swung to the right, 1 to the left, and 1 in the middle. Solid lines connect the bob to he support in the right and left positions. A dotted line connects the bob to the support in the center position. Dotted lines connect right, left, and center along the arc of the pendulum swing.
Which best explains what happens to the motion of the pendulum due to the law of conservation of energy?
The mechanical energy transforms to thermal energy as the pendulum slows and eventually stops moving.
The mechanical energy disappears as the pendulum slows and eventually stops moving.
The pendulum will continue moving at the same speed until someone stops it because energy cannot be destroyed.
The pendulum will slow down but will never stop moving because energy cannot be destroyed.
Answer: Don’t listen to the other person, B is incorrect. A is the correct answer.
Explanation: The law of conservation of energy states that energy cannot be created nor destroyed. B says that the mechanical energy disappears, but this is wrong. It changes into another energy, but the energy doesn’t disappear.
What happens to the motion of the pendulum due to the law of conservation of energy is that the mechanical energy transforms to thermal energy as the pendulum slows and eventually stops moving. Option A.
What does the law of conservation of energy state?The Law of Conservation of energy says that the amount of energy in an isolated system remains always the same, it does not increase nor decrease.
However, energy can be transformed and converted from one form of energy to the other.
Energy can not be created nor destroyed, it just changes from one form of energy to another.
This Law is, basically, giving us the answer to the question.
In the exposed example, the pendulum moves, and as it does it loses a part of the mechanical energy due to friction in the mechanical elements.
This lost mechanical energy is turned into the form of thermal energy.
Eventually, the complete transformation of mechanical energy into thermal energy causes the pendulum to stop.
The best explanation of what happens to the motion of the pendulum due to the law of conservation of energy is that the mechanical energy transforms to thermal energy as the pendulum slows and eventually stops moving.

Common symptoms of iron deficiency anemia muscle weakness, shortness of breath, and lightheadedness. Why does iron deficiency cause these symptoms?
Answer:
If your body lacks iron, it becomes difficult to make hemoglobin, because iron is needed to make that protein in order for oxygen to be carried around to your tissues and muscles.
Consider a population of 100 annual wildflowers, some yellow, some red. It is like other real populations, its gene pool is changing. For each of the scenarios below state which of the Hardy-Weinberg conditions the population deviates from, and explain what agent of microevolution causes the gene pool to change
Answer:
From normal to hybrid or different state.
Explanation:
According to Hardy-Weinberg conditions, the population deviates from present state to hybrid because of the change of gene pool. Genetic drift, natural selection and mutation are considered as agent of microevolution that is responsible for the change in gene pool. If the change in gene pool occurs the form and structure of population of organisms has to be change in its appearance.

Which of these events does not occur during telophase?
Answer:
A, the chromosomes dont ¨relax¨.
Explanation:
Chromosomes during telophase are doing all exept A
The event that does not occur during telophase is cytoplasm splitting into two, which is in the second option, because this phenomenon occurs after telophase, which is in the cytokinesis of the cell cycle.
What is the function of telophase?Telophase is the final stage of mitosis/meiosis and follows the stages of prophase, prometaphase, metaphase, and anaphase, during telophase, the chromosomes start to decondense and become less visible under the microscope, as they are no longer tightly packed together, and a new nuclear envelope begins to form around each set of chromosomes, creating two separate nuclei. There is no cytoplasmic division in the telophase.
Hence, the event that does not occur during telophase is cytoplasm splitting into two, which is in the second option.

Y is transcription, and Z is translation
Y is replication, and Z is translation
Y is translation, and Z is transcription
Y is translation, and Z is replication
Answer:
Y is transcription, and Z is translation
Explanation:
DNA to mRNA is the process of transcription (think how DNA and mRNA both have nitrogenous bases, so to get mRNA from DNA you have to transcript-a written or printed version of material originally presented in another medium- it). mRNA to protein is the process of translation (think how mRNA and proteins are made from different building blocks, mRNA being from nitrogenous bases and proteins from amino acids, so it must be translated). Therefore, Y is transcription, and Z is translation.

Which sentence describes a disadvantage of using nuclear fision to produce
electricity?
A. Fission changes one type of atom into another type of atom,
B. Fission produces only a small amount of energy
c. Uncontrolled fission reactions can result in dangerous explosions,
O D. Fission requires conditions that exist only in the cores of stars.
Answer is C
Answer:
C. Uncontrolled fission reactions can result in dangerous expolosions
Explanation:
The sentence describes a disadvantage of using nuclear fision to produce electricity is uncontrolled fission reactions can result in dangerous explosions. Thus, option C is correct.
Why nuclear fission is different from nuclear fusion?The two ways that nuclear fission is different from nuclear fusion include are the nuclear fission involves one large atom splitting into two smaller atoms and nuclear fission releases a huge amount of energy as the nuclear fusion involves the combination of two or more atoms while Nuclear fission involves one large atom splitting into two smaller atoms.
They both take place in the nucleus of the atom and can be used to generate electricity. They both release energy with the process of nuclear fusion releasing more than nuclear fission.
Fission produces only a small amount of energy and uncontrolled fission reactions can result in dangerous explosions as the Fission requires conditions that exist only in the cores of stars.
Therefore, The sentence describes a disadvantage of using nuclear fision to produce electricity is uncontrolled fission reactions can result in dangerous explosions. Thus, option C is correct.

5-Which of the following orientations of phospholipids best represents the
phospholipid bilayer of the plasma membrane? Explain your choice
A.
B.
C.
D.
Answer:
A
Explanation:
Option A is the orientation of phospholipids that best represents the phospholipid bilayer of the plasma membrane.
The phospholipid bilayer (the lipid layer) is known to be a thin polar membrane. It is usually made of two layers of molecules that are lipids. These are flat sheets which actually form a continuous barrier around the cells.
The phospholipid is a lipid which is made up of glycerol, two fatty tails and the head is phosphate-linked. The tails point inward and are arranged in a way called phospholipid bilayer.
Phospholipids are great for building the protective barrier around the cell of the body.
