What happens to the balloons as the nubber sheet is released ?Suggest an explanation for your observation. ​

Answers

Answer 1

When the rubber sheet is pushed upwards into a dome shape, the balloons become deflated. This is because the air volume inside the bell jar decreases, thus increasing the air pressure. As a result, the volume of the balloons decreases and the pressure increases.

I hope this helps :)

Which of the following is an ADVANTAGE of using coal for energy?

A. it has lots of impurities

B. it produces lots of ash

C. it releases lots of carbon dioxide

D. it releases lots of heat​

Answers

Answer:

the answer is D. it releases lots of heat

Coal releases lots of heat is an advantage of using coal for energy. Therefore, the correct statement is option D.

What are the disadvantages of using coal?

Coal is a fossil fuel that is used to generate energy in many parts of the world. When coal is burned, energy is released in the form of heat that generates electricity. Coal is a fossil fuel used for centuries to provide heat to homes, industries, etc., and provides a significant source of electricity in many parts of the world.

Coal is also relatively abundant and is easily transported, which makes it cost-effective for energy production. However, there are also several disadvantages to using coal.

Burning coal produces a large amount of carbon dioxide, a greenhouse gas contributing to climate change. Coal mining and transport also have negative impacts, such as air and water pollution, habitat destruction, and displacement of communities.

Therefore, coal releases lots of heat is an advantage of using coal for energy.

Answers

mice were essential to learning about the ways animals behave. for example, an expirement was made where some mice where isolated, and others weren’t. we found out that they learn much better when there’s more mice rather than being alone.

Mice are used as the model species to learn different behavior of animal, physiological activities and doing experiment on mice will give us the knowledge  to learn much better when there’s more mice rather than being alone.

Why Do We Experiment on Mice?

Choosing mice as model organism for experiments makes a sense for more imaginative than scientific, these are small, don't need a lot of space, don't cause much damage when it is provoked, safe to do experiment on mice in lab.

It can be easily modified genetically  which means scientists can manipulate any gene on any chromosome at any time, so that certain genes can be modified into inactive or turned off.

What is the circumference of a circle
with a radius of 28 m?

Answers

Considering the definition of circumference of a circle, the circumference of a circle with a radius of 28 m is 175.93 m.

Definition of circle and circumference

A circumference is a flat, closed, curved line whose points are the same distance from an interior point called the center.

The circle is the surface of the plane bounded by the circumference. That is, it is formed by all the points of the circumference and all the points of the plane inside it.

Definition of circumference of a circle

So, the circumference of a circle defines the length of the circle's outline. The circumference is also called the perimeter of the circle, because it is a measure of the limits of the circle.

That is, the circumference of a circle is the distance around the circle, also called the perimeter of the circle.

The expression to calculate the circumference of a circle "C" can be found by multiplying the number pi by the diameter of the circle "d":

C= π×d

The circumference of a circle can also be calculated using the length of the radius, considering the radius is half the diameter (or what is the same, the diameter is twice the radius):

C= π×2×r

Circumference of a circle in this case

In this case, you know the circumference of a circle has a radius of 28 m.

Replacing in the definition of circumference of a circle:

C= π×2×28 m

Solving:

C= 175.93 m

Finally, the circumference of a circle with a radius of 28 m is 175.93 m.

b) Methotrexate is a medication that prevents cells from making nucleotides. Explain how this could help fight a cancerous tumor.

Answers

The drug methotrexate belongs to the group of drugs known as antimetabolites. By reducing the growth of cancer cells, methotrexate treats cancer. In order to prevent the development of scales, methotrexate slows the growth of skin cells in psoriasis. Methotrexate may treat rheumatoid arthritis by reducing immune system activation.

Methotrexate obstructs the creation of DNA. This prevents cell division and growth, which slows or stops the growth of cancer. Cancer cells are more vulnerable to this harm because they divide more quickly and with less error-correcting than healthy cells do.

Acute lymphoblastic leukaemia (ALL), especially ALL that has progressed to the central nervous system, can be treated with methotrexate sodium alone or in combination with other medications.

how does the lipid bilayer of a membrane form a barrier to molecules

Answers

The lipid bilayer functions as a barrier to molecules Because it is made up of densely packed molecules with lengthy nonpolar hydrocarbon chains.

The lipid bilayer is a fundamental part of every cell membrane. Because it is made up of two layers of fatty acids arranged in two sheets, the structure is known as a "lipid bilayer." The lipid bilayer, which surrounds all cells and provides the cell membrane structure, is normally between five and ten nanometers thick. The lipid bilayer serves as a barrier, retaining ions, proteins, and other molecules where they are required while preventing their diffusion into unintended locations.

Simple Diffusion Across the Cell Membrane:

Answers

An early precursor to the development of neurofibrillary tangles and the neurodegeneration seen in Alzheimer disease, hyperphosphorylated tau protein (AT8 antibody) accumulates in transgenic mice overexpressing the RCAN1-1L protein.

Rats subjected to stress caused by immobility or isolation have higher levels in their hippocampus. Stress was applied to adult rats. Male Wistar rats that are eleven weeks old are cared for and worked on.

Acute stress may be protected against by transiently inducing the RCAN1 gene, but ongoing stress may lead to chronic RCAN1 overexpression, which can have dangerous side consequences. RCAN1 protein levels that are persistently increased may induce or aggravate a number of illnesses, including tauopathies like Alzheimer's disease. Through the inhibition of calcineurin and the stimulation of GSK-3 by RCAN1 proteins, stress can cause various disorders.

Answers

Using the 10% rule when studying trophic pyramids, if the primary consumers obtain 100 Joules of energy from the autotrophs Carnivores receive an energy transfer of 10 Joules.

Trophic level is referred to as the level of an ecosystem as well as a nutritive chain or food chain.

What does the trophic level 10% rule mean?

The trophic level 10% rule states that only 10% of the energy in an ecosystem will be transferred from one trophic level to the next.

Based on their eating habits, a chain of organisms is separated into various tiers. The producers, or green plants, make up the first and lowest stratum, the primary consumers or the herbivores make the 2nd trophic level and the carnivores or secondary consumers make up the 3rd trophic level and within these energy is transferred.

In this question, the herbivores obtain 100J of energy from autotrophs now according to 10% law only 10% of this energy will be transferred to carnivores thus,

10 = [tex]x[/tex]/100 ×100

Answers

The answer is A.

A right lateral strike slip fault. Now explaining one by one. So the first option tells about the dip slip motion of fault that is the motion along the dip direction of the fault. In this case there is no dip slip component as the blocks have moved horizontally along strike direction.

Fault produced by stretching are known as normal fault. Normal fault includes foot wall and hanging wall. But here the fault is vertical so there are no foot wall and hanging wall distinguishable.

The fault strikes NE -SW. So option B is not correct.

Now Only the option A. Strike slip fault is a vertical or nearly vertical fault with net displacement along the strike direction. The blocks have moved horizontally. If we refer to the man standing on one block ,then his front block has moved towards his right hand side. So the fault is known as Right lateral strike slip fault.
