If a cell's surface area-to-volume ratio increased from 3:1 to 4:1, what impact would that have on the transport of materials across the cell membrane? It would be unchanged Transport would increase Transport would decrease None of the above

Answers

Answer:

The answer to this question is Transport would increase.

Explanation:

The transport would just increase.

In the given area-to-volume ratio, the transport would increase across the cell membrane. The correct option is B.

What is area-to-volume ratio?

The surface area to volume ratio is merely the surface area divided by the volume of an entity. It calculates the surface area per unit volume of the object.

The crucial fact is that as the cell size increases, the surface to volume ratio decreases.

If the cell expands beyond a certain size, not really enough material can cross the membrane quickly enough to cater the increased cellular volume.

The surface area divided by the volume is the ratio. This suggests how much surface area is accessible in relation to the size of the cell.

The cell is very large if the surface area to volume ratio is small. If the ratio is large, the surface area exceeds the volume the cell will be small.

Thus, the correct option is B.

3. Compare and contrast the movement produced by each of the three types

Answers

Answer:

strike-slip is when the blocks have mostly moved horizontally, normal is when a dip-slip fault in which the block above the fault has moved downward relative to the block below, and thrust is when the hanging wall moves up relative to the footwall.

There are three faults. Normal faults originate from the divergent boundary. Reverse faults originate from the convergent boundary. Strike-slip fault originate from transforming boundary.

What are the three types of fault?

We can differenciate three types of faults,

Normal fault ⇒ originate from divergent movementReverse fault ⇒ originate from convergent movementStricke-slip fault ⇒ originate from transforming movement

What are the boundary types?

I. Divergent:

This boundary occurs when two plates separate and molten material rises from the mantle creating a new crust.

The hot material creates a new seabed between the separating plates, expanding the sea bottom.

II. Convergent.

Collision area between two plates. Two oceanic plates might collide, or one oceanic plate with a continental one.

In this last case, the oceanic crust sinks under the continental plate, and magma rises to the surface by crevices.

The thicker and older plate subduces under the other plate.

III. Transforming.

The plates slide laterally with each other, and they are usually called faults.

It is associated, in general, with the oceanic ridge, although it might also occur in the continental plate.

No rocky material is either destroyed or formed.

When the plates move and produce a displacement of one transforming limits from side to side, earthquakes occur.

The movement breaks the crust and originates pronounced fractures.

Huntington’s disease (HD) is prevalent South Africa. Most of the families with HD have Dutch or British ancestry, which suggests they inherited the European HD allele. HD is believed to have first arrived in South Africa more than 300 years ago when Dutch colonists settled into the Western Cape in the 1600s. Thus, the prevalence of HD in South Africa is the result of the founder effect.

Mutations in the HTT gene cause Huntington’s disease. The HTT gene provides instructions for making a protein called huntintin. This protein plays a role in nerve cells in the brain. The HTT mutation that causes HD involves a DNA segment known as a CAG trinucleotide repeat. This segment is made up of a series of three DNA building blocks that appear multiple times in a row. Normally, the CAG segment is repeated 10 to 35 times within the gene. In people with HD, the CAG segment is repeated 36 to more than 120 times. An increase in the size of the CAG segment leads to the production of an abnormally long version of the huntintin protein. This causes the dysfunction and eventual death of neurons in certain areas of the brain. The more repeats, the more serious the disease is.

HD is inherited in an autosomal dominant pattern. There is both an adult onset (after reproductive age) and a juvenile onset pattern. People with adult onset typically have 40 to 50 repeats, while people with the juvenile form tend to have more than 60 repeats. Individuals who have 27 to 35 repeats do not develop HD, but they are at risk of having children who will develop the disorder. As the gene is passed on to offspring, the size of the repeat may lengthen into the range associated with HD.

Predict what will happen to the allele frequencies for Huntington’s disease in South Africa if there were a new mutation to the HTT gene that causes a reduction to the CAG trinucleotide repeat. Justify your prediction with evidence. Your response should include links to the sources of information gathered.

output is 5 units, where does the
95% of the energy input go?
A. lost as heat
B. lost as gas
C. escapes the system as potential energy

Answers

I looked it up and the answer is A because lots of electricity is lost as heat through conductors. i also found stuff for the other answers but this seemed the most accurate and credible.

If a power plant uses 100 units of energy to create electricity and the output is 5 units, 95% of the energy input goes as lost as heat.

Could you ever create a machine where 100% of the input energy would turn into output energy?

No, a real machine can't have an efficiency of 100%. An efficiency of 100% means that there is no loss and the output energy (or work) of the machine is equal to input energy (or work). In real machines, there is always some loss of energy to overcome friction and air resistance.

How do you calculate the energy efficiency of a power plant?

To express the efficiency of a generator or power plant as a percentage, divide the equivalent Btu content of a kWh of electricity (3,412 Btu) by the heat rate. For example, if the heat rate is 10,500 Btu, the efficiency is 33%. If the heat rate is 7,500 Btu, the efficiency is 45%.
