Why can you not create a Punnett square to determine the height of an individual?
Answer:
Punnett squares do not provide accurate predictions on the distribution of phenotypes in offspring. ... This makes it difficult to make predictions regarding Down's syndrome since it cannot predict the prevalence of the offspring's genotypes about a population.
Explanation:
Limitations of Punnett squares as models of inheritance include the lack of information about likely variation in small samples such as individual families and the lack of information about population prevalence of parental genotypes (so no predictions can be made about population prevalence of offspring genotypes.

The pressure of the gas increases.
The pressure of the gas remains same.
The number of collisions of gas particles decreases.
The number of collisions of gas particles remains same.
Answer: C. The number of collisions of gas particles decreases
Explanation: As temperature decreases so does everything else same with increase.
When the number of particles of a gas decreases the pressure of the gas increases.
Factors affecting has pressureIn a container containing has molecules, they move about freely in the container but the pressure it exerts on its container depends increase of decrease of the has molecules by volume.
If the volume of a container is decreased, the gas molecules have less space in which to move around. As a result, they will strike the walls of the container more often and the pressure increases.
Therefore, when the number of particles of a gas decreases the pressure of the gas increases.

Answer:
D
Explanation:
Scientists will use a scientific notation because, it provides the easier way to write a very large and very small numbers. Option D is correct.
Scientists use scientific notation to express numbers that are extremely large or small. Scientific notation allows for a more concise representation of these numbers by expressing them as a product of a coefficient and a power of 10.
For very large numbers, scientific notation makes it easier to handle and compare values. It allows scientists to focus on the significant digits and the scale of the number without having to write out all the zeros. It also simplifies calculations and reduces the chance of errors when dealing with such large values.
Similarly, for very small numbers, scientific notation provides a convenient way to express values without writing out a large number of decimal places. It allows scientists to express the magnitude of the number in a concise manner and enables easier comparison and calculations with other values.
Scientific notation is widely used in scientific fields such as physics, chemistry, astronomy, and engineering, where dealing with numbers of varying magnitudes is common. It provides a standardized and efficient way to represent and work with very large and very small numbers.
Hence, D. is the correct option.

How would the balloons interaction with each other change if the balloons were moved further apart? Explain.
Explanation:
It is known that like charges repel each other and unlike charges attract each other.
As the balloons are facing each other with like charges so they will repel each other. Hence, they will move apart.
But when balloons were moved further apart then interaction between them will decrease and then there will be no force of repulsion or force of attraction.

What do you notice about the distance between the terrestrial planets compared with the spacing between the gas giants
Answer:
The spacing between the terrestrial planets is less than that between the gas planets.
Explanation:
Since the terrestrial planets which are Mercury, Venus, Earth and Mars have a distance of 0.4 AU, 0.7 A.U, 1.0 AU and 1.5 A.U respectively from while the gas planets which are Jupiter, Saturn, Uranus and Neptune have a distance of 5.2 AU, 9.6 AU, 19.6 AU and 30 AU respectively from the sun, we can see that the spacing between the terrestrial planets is much smaller than the spacing between the gas planets.
For example, the spacing between Mercury and Venus is 0.7 AU - 0.4 AU = 0.3 AU while that between Earth and Venus is 1.0 AU - 0.7 AU = 0.3 AU.
Also, the spacing between Earth and Mars is 1.5 AU - 1.0 AU = 0.5 AU.
Also too, the spacing between the gas planets is shown below the spacing between Jupiter and Saturn is 9.6 AU - 5.2 AU = 4.4 AU while that between Uranus and Saturn is 19.6 AU - 9.6 AU = 10.0 AU.
Also, the spacing between Neptune and Uranus is 30 AU - 19.6 AU = 10.4 AU.
Thus, we can see that the spacing between the terrestrial planets is less than that between the gas planets.
Note that AU means astronomical unit and 1 AU is the distance between the Earth and the Sun. 1 AU = 1.50 × 10⁸ km

Compare the following in the three states of matter
a) inter particle space
b)inter particle force of attraction
c)particle motion
Explanation:
Anything that occupies space and has mass is called matter.
(a) Inter particle space
Solids - Atoms of a solid substance are closely packed with each other due to which there is very less or no inter particle space.Liquids - Atoms of a liquid are little loosely packed due to which there is some inter particle space.Gases - Atoms of a gas are very loosely packed due to which there is large inter particle space.(b) Inter particle force of attraction
Solids - Atoms of a solid are attached to each other by strong force of attraction.Liquids - Atoms of a liquid have slightly less force of attraction as compared to a solid substance.Gases - Atoms of a gas have Vander waal forces. Hence, there is no inter particle force of attraction between atoms of a gas.(c) Particle motion
Solids - There is low or negligible particle motion between atoms of a solid.Liquids - There is high particle motion as compared to that present in a solid.Gases - There is very high particle motion as compared to solids and liquids.How many Group 17 elements are in Period 3 of the Periodic Table?

PreviousNext
Answer:
the molecules strike the walls of the container more often.
Explanation:
The pressure of a gas refers to the force per unit area exerted on the walls of container by gas molecules.
Since the average kinetic energy of gas molecules increases as the temperature of the gas increases, the molecules of the gas tend to strike the walls of the container more often as the temperature of the gas increases.
Hence, the pressure of a gas increases due to an increase in temperature because the gas molecules strike the walls of the container more often.
