Answer:
Option C is correct
Explanation:
Entropy is defined as the randomness in a system. In nature, a system tends to have high entropy. The higher the entropy , the spontaneous the reactions would be. As a system loses energy, it becomes more ordered and less random. Hence, as the reaction proceeds in a system, the system has higher energy/entropy and less order.
Hence, option c is correct

Which of these statements best describes which traits are expressed by an organism? A. An organism expresses all the traits for which it carries genes.
B. An organism expresses only the traits whose genes are inherited from a parent.
C. An organism expresses only the traits whose genes it will pass on to its offspring.
D. An organism expresses some traits for which it carries genes while others are dominant
The statement that best describes which traits are expressed by an organism is A.
An organism expresses all the traits for which it carries genes. This is because an organism's traits are determined by the combination of genes it carries, which includes both dominant and recessive genes. Even if a trait is not expressed in an organism, it can still be carried in its genes and passed on to its offspring. Therefore, all the traits for which an organism carries genes have the potential to be expressed in either the organism or its offspring.
B-An organism expresses only the traits whose genes are inherited from a parent.

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.

A 10-ft moving truck has a volume capacity of 402 cubic feet, which is equivalent to 1.138 x 10^7 milliliters. What
mass of silver, in megagrams, will fit in this moving truck? The density of silver is 10.49 g/mL.
_________ Mg (input numerical answer only)
Answer: The mass of silver is 1.19 X 10^14 M g
Explanation: The volume of the truck is 402 cubic feet or 1.138 x 10⁷ mm.
The density of silver is 10.49 g/mL.
We need to find the mass of silver that will fit in this moving truck. Density equals mass divided by volume. So,
d= m/v where m= mass m= d x VM=10.49 g/mL X 1.138 X 10∧7 mLM=119376200 g 1 gram=10⁻⁶ Megagram 119376200= 1.19 X 10^14 Mg hence the mass of silver is 1.19 X 10^14 M g hopefully this will help you please mark me as brainlist

In our experiment that will compare how long it will take for 100 ml distilled water to evaporate from a from a 5" diameter container. This will be the control group. For the experiment group, we will use 100 ml of distilled water and dissolve 10 grams of table salt in the water. We will use the same diameter dish for both samples so the same amount of water surface is exposed to the air.
What would a good hypothesis be?
When the salt water was almost evaporated, the higher concentration of salt might have slowed the evaporation process by blocking the air from the moisture.
We think that a pure water sample will dissolve faster than a salt water solution because salt adds more mass to equal quantities of liquids.
It took a total of 31hrs. 15 min. to evaporate the pure water and 32hrs. 10 min for the salt water.
We poured the water into each 5" dish and set the containers on a table. We noted the time: 8:00 a.m. Saturday.
Answer:The answer is C: How long does it take distilled water to evaporate from a 5” diameter container?
Explanation:
In the air, a salt solution will evaporate more slowly than pure water.
What is Evaporation?
The process by which a liquid transforms into a gas state is called evaporation. A surface phenomena, that is. The amount of evaporation depends on the humidity. If the air is humid, it is virtually saturated, which means that evaporation will occur at a much slower rate.
Since evaporation takes place on the liquid's surface, the salt molecules that are present on the water's surface prevent as much water from evaporating. As a result, salt water evaporates more slowly than pure water.
As a result, the salt solution will evaporate from the air more slowly than pure water.

Explanation:
What is causing the increasing amount of CO2 in the atmosphere? What could be done about it?
Photosynthesis begins when chlorophyll molecules in the plant absorb light energy from the sun. Along with sunlight, CARBON DIOXIDE (CO2)/OXYGEN (O2) and HYDROGEN (H)/WATER (H2O) are also taken in by the plant. Light energy from the sun FUSES/SPLITS water molecules (H2O) into hydrogen (H) atoms and oxygen (O) atoms. Pairs of oxygen atoms combine to form oxygen gas (O2). The oxygen gas (O2) leaves the plant as a WASTE/SUGAR product. The carbon dioxide (CO2) and hydrogen (H) molecules are made into WASTE/SUGARS, which are used by the plant to make energy. Also during this process, light energy from the sun transforms into THERMAL/CHEMICAL energy that is stored in sugars.

If the Yellowstone volcano erupts I hope to find my family and I would stay at home. I believe that after this event, the sky would be opaque for a long time due to ash, something similar to the mass extinction of dinosaurs.
What is the Yellowstone volcano?The Yellowstone supervolcano is a volcanic caldera located in Yellowstone National Park (Wyoming) in the United States. The caldera measures approximately 55 × 72 km.
This volcano was formed during the last of the three super-eruptions that occurred over the last 2.1 million years.
What would happen if this supervolcano erupted?If the Yellowstone supervolcano were to erupt, it would produce a massive ash shower that would cover the entire United States for decades.
On the other hand, the climatological conditions would be modified, given the magnitude of the geological formation that rests, still active, below the National Park.

Which type of selection is shown in the graph above?
A. Disruptive selection
B. Stabilizing selection
C. Disaster Selection
D. Directional selection
In the given graph, the Evolved Population is showing disruptive selection. Hence, the correct option is A. Disruptive selection.
Stabilizing selection is a form of natural selection where individuals with average phenotypes are more likely to survive and reproduce their number. In this selection, the population tends to maintain a stable phenotype. As shown in the graph, the population is maximum for the population having a moderate length of neck.
Disruptive selection is a type of natural selection where extreme phenotypes are preferred over average phenotypes, leading to an increase in genetic variation and the population becoming more diverse. In this type of selection, the population diverges into two or more distinct phenotypic groups. As shown in the graph, two ranges of the population are favored for having traits for extreme lengths of the neck.

When the speed of the bottle is 2 m/s, the KE is kg m2/s2. When the speed of the bottle is 3 m/s, the KE is kg m2/s2. When the speed of the bottle is 4 m/s, the KE is kg m2/s2. When the speed of the bottle is 5 m/s, the KE is kg m2/s2. When the speed of the bottle is 6 m/s, the KE is kg m2/s2.
instructions
In this part of the experiment, you will be changing the speed of the bottle by dropping it from different heights. You will use the same mass, 0.250 kg, for each trial, so record this mass in Table B for each velocity. Then, calculate the expected kinetic energy (KE) at each velocity. Use the formula KE = mv2,
where m is the mass and v is the speed. Record your calculations in Table B of your Student Guide.
Answer:
Based on the given instructions, you need to calculate the expected kinetic energy (KE) at each velocity using the formula KE = mv^2, where m is the mass and v is the speed. The mass is given as 0.250 kg.
Table B: Calculation of Kinetic Energy (KE)
Table B: Calculation of Kinetic Energy (KE)

To calculate the kinetic energy at each velocity, multiply the mass (0.250 kg) by the square of the velocity.
For example, when the speed of the bottle is 2 m/s: KE = (0.250 kg) * (2 m/s)^2 = 0.250 kg * 4 m^2/s^2 = 1.000 kg m^2/s^2
Perform similar calculations for the other velocities and record the results in Table B.
Answer:
Explanation:mass of the bottle in each case is M = 0.250 kg
now as per given speeds we can use the formula of kinetic energy to find it

kinetic energy is given as
2) when speed is 3 m/s
