Plzzzz help Creating models to examine concepts is important in science. Some of these are experiments
and only one is a model. Which one is a model?
a
O A heated soda can is cooled rapidly to see what will happen to air pressure.
O An apple is sectioned into quarters to represent the ratio of water to land on Earth.
O Ice cubes are left to melt on different surfaces to find out how materials conduct heat.
O Students conduct a color blindness test with their family members.
Knowing that a model is considered a representation of something, the correct option is option B, in which the apple represents the Earth. An apple is sectioned into quarters to represent the ratio of water to land on Earth.
--------------------------------
To answer this question, you can think about a model as a representation of something.
A scientific model can represent an object, a system, a process, a phenomenon, etcetera.
Models are used to explain, predict, or describe natural events. They constitute a significant tool in modern science and are essential to scientific practice.
Knowing this, among the provided options, the one that is a model is option B.
The apple is representing the ratio of water to land on Earth. It is a representation of the earth.
All the other options are experiments performed to see what is going to be the result.

If you cross two organisms that are heterozygous for a trait, what percent of
the offspring would you expect to express the recessive phenotype?
Answer:
25%
Explanation:
Here's an example: two chickens have the phenotype of white feathers and brown feathers. What percentage of the chicks will have the recessive color? First, you have to see the parents' phenotypes. Draw a punnet square. Put one of the parent's phenotypes (w and B) on the top, and the other parent's (w and B) on the right side going down. Whichever trait is dominant (brown) MUST be capitalized. Then, cross the two parents. first box on the top left would read 'ww.' The one below it is 'Bw' (put the dominant first). The right top is 'Bw' and the one below it is 'BB'. So if there were 4 offspring, these would be their genotypes: 'ww', 'Bw', 'Bw', and 'BB'. The only offspring that would have the recessive trait is the 'ww' child, because dominant overpowers recessive. So 25% would have the recessive trait and 75% would have the dominant trait.
why are different leads are used to measure the ECG
Different leads are used to measure the ECG simply because each lead is recording the electrical activity of the heart from a different direction
Each individual lead's ECG recording is slightly different in shape. This is because when the electrical activity within the heart travels towards a lead you get a positive deflection.
ElectrocardiogramAn electrocardiogram (ECG) is a simple test that can be used to check the heart's rhythm and electrical activity. Sensors attached to the skin are used to detect the electrical signals produced by your heart each time it beats
ElectrocardiographyElectrocardiography is the process of producing an electrocardiogram, a recording of the heart's electrical activity.

An area that has been sampled to have a large population of organisms. Does this represent high biodiversity? Why or why not?
An area that has been sampled to have a large population of organisms is
regarded as having a high biodiversity.
Biodiversity is defined as the condition in which areas have a high amount
of plant and animal species present there. Any place with a large population
of organisms is said to have a high biodiversity while places with low
population of organisms have low biodiversity.
The stated facts therefore makes an area that has been sampled to have a
large population of organisms represents high biodiversity.

Answer:
In the alveoli, where there is high pO2, low pCO2, lesser H+ concentration and lower temperature, the factors are all favourable for the formation of oxyhaemoglobin, whereas in the tissues, where low pO2, high pCO2, high H+ concentration and higher temperature exist, the conditions are favourable for dissociation of oxygen from the oxyhaemoglobin. This clearly indicates that oxygen gets bound to haemoglobin in the lung surface and gets dissociated at the tissues
