Which is not a property of water?
Select one:
a. good solvent for electrolytes
b. high specific heat
c. adheres to polar compounds
d. contracts during freezing
d. Because when liquid water becomes solid ice, it expands, not contracts.
Water contract during freezing is not a property of water.
Option D
Explanation:
The water at normal temperature is fluid in nature where the disorder in the structure is due to the hydrogen bond between the molecules of water which are continuously forming with one molecule and then again forming with another molecule.
When the water freezes then due to low temperature the energy of the system is lost due to which vibration between the element is also reduced and hydrogen bonds no longer change. At this time the fixed hydrogen bond causes the molecules of water to expand which further decreases the density of water.
Dale makes a model of part of an elemental solid by attaching balls to each other with rods. His model looks something like the following image:
How could Dale improve his mode
A.
by using springs instead of rods to allow the model atoms to vibrate in their positions
B.
by using strings instead of rods to allow the model atoms to move more freely
C.
by using different sizes of balls to represent different kinds of atoms
D.
by using cotton balls instead of hard balls to allow the model atoms to change size
Answer:
by using springs instead of rods to allow the model atoms to vibrate in their positions
Explanation:i got it correct
Answer: Option A
Explanation:
The strong inter molecular forces that is found in solids does not allows the atoms to move out of the solid but it allows them to vibrate on its position.
The atoms in the solid are joined together by strong inter molecular forces that does not allows the atoms to move out of the bond but due to kinetic energy the atoms keeps them vibrating even if they remain in their position.
Hence, the correct answer is option A because the model must have been substituted with a spring inspite of rods.

C. It is quite likely because both the caiman and parrot have had amniotic eggs and they share recent common ancestor with the T. Rex.
D. Probably not because the T. Rex is no longer living.
I’m failing biology, help a girl out!
I know that It has an amniotic egg so It is either B or C
Final answer:
The T. Rex most likely had an amniotic egg, as it is a characteristic of amniotes. Close relatives of the T. Rex, like the caiman and parrot, have had amniotic eggs, indicating that the T. Rex probably had them too.
Explanation:
The T. Rex most likely had an amniotic egg. Amniotic eggs are a characteristic of amniotes, which include reptiles, birds, and mammals. The evolution of amniotic eggs allowed for the development of embryos within an aquatic environment inside the egg, which reduced the dependence on a water environment for development. Although the T. Rex is no longer living, its close relatives, such as the caiman and parrot, have had amniotic eggs, indicating that the T. Rex probably had them as well.
The image shows a type of stress.
Which type of fault occurs when rock is subjected to this type of stress?
hanging
normal
reverse
strike-slip
Answer:
Option C, Reverse
Explanation:
A reverse fault is one in which compression force squeezes the rock crust into small space due to which the hanging wall will push up to a higher level as compared to a footwall. Here in this image none of the block is pulled away or forced towards the other. However, the rock has broken due to the application of compressive force which will now tend to create a reverse fault
Hence, option C is correct

Julie’s town uses single-stream recycling, so Julie puts all of her household recyclables in a single container to be picked up. The recycling plant must sort out the different materials, including paper, cardboard, different types of plastic, glass bottles and jars, aluminum drink cans, and steel food cans.
How would an electromagnet be used in this type of recycling plant?
to remove plastic bottles from glass bottles
to divide food cans from soft-drink cans
to separate paper from cardboard
to gather colored glass from colorless glass
Answer:
to divide food cans from soft-drink cans
Explanation:
An electromagnet is based on the principle that current through a coil produces magnetic field. Magnetic objects such as Iron, nickel, cobalt or objects made from their combination are attracted by the magnet. This property is used to separate materials in recycling plant.
Steel (alloy of iron) would be attracted by the magnet where as aluminium would not be. Thus, steel food cans can be separated from the aluminium soft-drink cans using an electromagnet.

Which of the following gases , released by ruminant animals and termites as a waste product of digestion , can add to global warming ??
A. Carbon dioxide (co2)
B. Methane (CH2)
C. Chlorofluorocarbon (CFC)
D. Nitrogen (n2)
B. Methane (Ch2) is released by animals and contributes to global warming
Methane (CH4) is released by ruminant animals and termites as a waste product of digestion. It is produced through a process known as enteric fermentation and cellulose decomposition, respectively. This potent greenhouse gas absorbs heat in the atmosphere, contributing to global warming.
Explanation:The ruminant animals and termites release the gas called methane (CH4), not CH2 as a waste product of digestion. Methane is a potent greenhouse gas that can contribute to global warming. When methane is released into the atmosphere, it absorbs the sun's heat, warming the atmosphere. This is known as the greenhouse effect, and it is a significant contributor to global warming.
Ruminant animals, such as cows, sheep, and goats, produce methane through a process of enteric fermentation. In their stomachs, microorganisms break down carbohydrates into simpler molecules, which produce methane as a byproduct. This methane is then exhaled or belched out by the animal.
Similar to ruminants, termites also generate methane. They produce methane in their gut, as they are decomposing cellulose from the wood materials they are eating. The microbiota in their gut produces methane gas as a metabolic byproduct, which is then released into the atmosphere.

Some bed bugs had mutations in their genetic code which allowed them to survive the chemical pesticide and they produced chemically resistant offspring. How can this be explained?
Answer:
Random mutations led to evolution of pesticide resistance genes in bed bugs.
Explanation:
Random mutations in genome of bed bug imparted them the pesticide resistance. Since the bed bugs having the mutation of pesticide resistance were able to survive under presence of pesticides, this variation was favored by natural selection. The bugs with pesticide resistance transmitted this trait to their progeny. In time, the bed bug population consisted of most of the bugs having the pesticide resistance.

3. How often does the sun's magnetic field reverse?
A. Every 11 years
B. Every two million years
C. Every 100,000 years
D. Every 350 days
Answer:
A. Every 11 years
Explanation:
It happens at the peak of each solar cycle as the sun's inner magnetic dynamo re-organizes itself. The coming reversal will mark the midpoint of Solar Cycle 24.
The sun's magnetic field reverses A. Every 11 years.
The Sun's magnetic field undergoes a complete reversal of its polarity approximately every 11 years. This phenomenon is known as the solar magnetic cycle or the solar cycle. The cycle starts with the Sun's magnetic field being oriented in a particular direction, and over the course of about 11 years, it gradually flips its polarity, with the north and south magnetic poles interchanging.
The solar magnetic cycle is driven by the complex processes occurring within the Sun's interior. It involves the generation and interaction of magnetic fields through processes such as differential rotation, convection, and the dynamo effect. These processes generate and amplify the magnetic fields, leading to the periodic reversal of the Sun's magnetic polarity.
Therefore, the correct answer is A. Every 11 years.

Which MOST LIKELY represents the gas being released and the process used to make it?
I believe that the gas is Carbon dioxide and that it is being released by respiration.
The gas being released is carbon dioxide and in the process called cellular respiration.
In apparatus set up by the students, the yeast used the sugar in the apple juice together with the oxygen to generate adenosine triphosphate (ATP) and releases carbon dioxide as a waste.
Further ExplanationYeast is a one-celled organism that requires energy to survive. Yeast can do anaerobic and aerobic respiration. For yeast to survive, it has to make its energy.
To survive, yeast uses cellular respiration, where glucose is transformed into ATP and carbon dioxide.
In other words, cellular respiration is a metabolic process that involves the breaking down of glucose to generate adenosine triphosphate (ATP) and releases waste products. The waste product is carbon dioxide (C02)
Cellular respiration is used by both plants and animals to break down sugar and convert it into energy. The energy produced is used by plants and animals to carry out some task at the cellular level. The essence of cellular respiration is to provide the energy required for cells to function.
Therefore, in the apparatus set up by the students, the yeast used the sugar in the apple juice together with the oxygen to produce adenosine triphosphate (ATP) and discharges carbon dioxide as a by-product.

A population of peppered moths is monitored over several generations. It is observed that the number of white moths compared to the number of black moths changes with each successive generation. This means that the population cannot be at equilibrium and the population is therefore evolving.
True
or
False
Answer:
True
Explanation:
Evolution is the change in the characteristics of a population over generations. This is caused by nature selecting out some disadvantageous traits and preserving advantageous traits over successive generations through natural selection pressures. In this case, the white moth is at a disadvantage in the environment compared to the black moth. The allele for white color is, therefore, ‘weeded out’ over time.
