A student makes a model of the water cycle by using a cup, some water, and plastic wrap. After the student places the model near a sunny window, moisture forms on the inside of the plastic wrap. What change is the student most likely observing in this? A. Freezing B. Condensation C. The warming of air or D. Evaporation
Could someone explain what the answer is and why it's the answer because I don't understand.
Answer:
The answer is D
Explanation:
When water heats up the water molecules speed up so they turn into a gass. Since the water vapor has nowhere to go it sticks to the plastic wrap on the inside of the cup.

Explanation:
Louise has put together the setup shown in the figure to investigate how different masses respond to different forces. A mass is attached to two stretched springs. It rides on a track with very little friction. When Louise pushes the mass to either side and then lets it go, it oscillates back and forth, much like a pendulum. Explain why the mass oscillates.
Answer:due to the kinetic energy stored in spring
Explanation:
this happen because when spring ia stretched it store kinetic energy and it has the ability to move back and forward so this happen
Due to stored kinetic energy in the spring, the mass oscillated like a pendulum.
It is given that a mass is attached to two springs that are stretched. When Louise pushes the mass to either side and then lets it go, it oscillates back and forth resembling a pendulum.
This movement is observed because the mass if the block placed is shared between the two springs. This let the two springs to store the energy in them. This could also be given as potential energy.
When the mass is moved in the either side, the potential energy in the springs are turned into kinetic energy leading to movement of the mass. Since, the mass is help up with two springs, oscillatory movement or to and fro motion of the spring is observed.

Ionic and covalent bonds help arrange atoms into unique structures for proteins like hemoglobin. Why is this necessary?(1 point)
Answer:
Ionic bonds can be important to protein structure because they are potent electrostatic attractions. In the hydrophobic interior of proteins, ionic bonds can even approach the strength of covalent bonds
Covalent bonds in amino acids are useful to stabilize the structure of the proteins and their interactions. The ionic bond formed as the atoms in amino acids with opposite charges accompanied strong electrostatic attractions.
What types of bonds are involved in protein structure?Proteins are 3D structures of amino acids that are further made of an amine and a carboxyl group, and are arranged in specific structures in four levels to give rise to the complete protein molecule.
Proteins can be described as the polymers of polypeptides which are structured by arrangements of these chains in a three-dimensional structure. They are folded and are driven by special non-covalent interactions such as peptide bonds, ionic bonds, hydrogen bonds, Van der Waals interaction, and disulfide bridges.
The primary structure is the sequence of amino acids through peptide bonds to form a polypeptide chain. The secondary structure is a sub-structures made by hydrogen bonding between the main chain peptide groups on the polypeptide backbone chain.
Tertiary structure is the 3D arrangement of protein in which α and β helices are folded into a globular structure with the interactions such as hydrogen bonds, salt bridges, disulfide bonds, and tight packing of side chains.

A.Your vegetables will win prizes for being unusually large.
B.Anything you grow will be at high risk for pesticides and diseases.
C.Your land could stop producing vegetables altogether.
D.Your land will be worth less money.
If crops are not getting proper nutrients from soil we may have to apply fertilizers which adversely affect the soil if no nutrient is restored to soil, it will not produce vegetables and your land will be worth less money. Thus, options C and D are correct.
What are nutrients?Nutrients are ions, minerals and proteins that is very essential for living things. Without proper nutrition, the growth of both plants and animals become will be declined.
Plants needs some elements such as nitrogen, potassium, calcium, phosphorus etc. for their growth. They absorbs these ions and water from soil and distribute all over its body through channels.
If plants are getting no nutrients from the soil their will not grow and no new vegetables will be formed in such a land where there on management to restore soil nutrients.
In such situations, we have to apply fertilizers which have may bad impacts too. Hence, without nutrients the vegetables will not grow and the land will be worth less of money.

In an electrical wire, if instead of copper, plastic wire is used. Would it conduct electricity?Justify your answer.
Answer:
No, a plastic wire would not conduct electricity. This is because plastic is an insulator that does not allow electric current to flow through it. In a wire, electrical conductivity is provided by the movement of charged particles - typically, electrons. Copper is an excellent conductor of electricity because it has a high number of free electrons that are not bound to atoms and can move through the wire very easily. However, in a plastic wire, the tightly bound electrons of its atoms do not allow for the free flow of charges, thus preventing the passage of electric current.
1. Using D10W and a vial of NaCl 4 mEq/mL, how many mL of NaCl are needed to prepare 250 mL of a
D10/NS solution?
a. 4.8mL
b. 9.6ml
c. 19.6mL
d. 154mL
To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.

Answer:
6.It is concluded that while high temperature has an unfavourable effect on seed set of radish plants, it also weakens the incompatibility reaction between pollen and style, so that the result is a small increase in yield.
7.The result of the study showed that music with a higher intensity is more distracting and has a greater effect on task performance and concentration. The result helped formulate the Attention Drainage Effect theory, which is based on Kahneman's (1973) capacity model of attention
8. If the food is more colorful then the fish will eat more because they're more interested in the colors
9.If plants do not receive enough light, they will not grow at their maximum rate or reach their maximum potential, regardless of how much of any other variable – water, growth medium or fertiliser – they receive. Light is the driving force for photosynthesis, a plant process that changes sunlight into chemical energy. Plants need five things in order to grow: sunlight, proper temperature, moisture, air, and nutrients. These five things are provided by the natural or artificial environments where the plants live. If any of these elements are missing they can limit plant growth.
The independent (or manipulated) variable is something that the experimenter purposely changes or varies over the course of the investigation. The dependent (or responding) variable is the one that is observed and likely changes in response to the independent variable.
