An F1 cross between true breeding brown and white lines is set up. What evidence would best support white fur being dominant to brown -----

The best evidence to show that white fur being dominant is when all the offspring after the cross are white instead of brown

They are therefore expected to produce heterozygous lines.

The evidence that would best support white fur being dominant is when all the lines produced are white despite being heterozygous.

A dominant trait is known to mask the expression of other traits.

Given what we know about the water cycle we can confirm that the process that happening in the biome is the process of condensation

Although the water cycle can be divided and subdivided into various processes, we can simplify it into four simple steps:

The one saw in the biome and one of the most essential parts of the cycle is condensation. It is the collection of water molecules into a single group that, when dense enough, fall back onto the earth as rainfall. In nature these take the form of clouds, meanwhile, in the biome, they appear as water on the sides of the container.

Explanation:

The organisms living in an aquatic environment have to undergo osmoregulation and survive in a hypotonic environment. The organisms such as paramecium, protists, and unicellular algae have contractile vacuoles.

The functions of the contractile vacuoles include:

1. Contractile vacuoles help in the osmoregulation, such that the movement of solute particles inside and outside of the cells.

2. The contractile vacuoles are also required to remove excess water from the organisms.

3. The vacuoles contract to discharge the fluid for the survival of organisms like paramecium and algae.

Thus, the contractile vacuoles contract to allow the organisms to survive in a hypotonic environment.

The effects the pressure inside Earth likely had on the density of materials in Earth’s core

It is made up of rock that is molten with slow-moving currents under the effect of increasing pressure and temperatures between 1,600 and 4,000 °F. Volcanic eruptions and earthquakes are caused by movement in the mantle layer.

Similar to how the temperature rises from the surface of the planet toward its center, so do the pressure. It is because of the heavy materials above, such as rocks.

The air density inside the International Space Station is kept at a level that is comparable to that of the surface of the planet. Consequently, the air pressure in the space station is equivalent to.

Therefore, the tremendous pressure inside Earth has the effect of reducing the volume of the materials, increasing their density.

Explanation:

It is true that when heat is supplied to one end of a long metal rod, then which spreads at once in the entire rod.

Conduction is the transfer of heat energy through collisions between neighboring atoms or molecules.

Conduction occurs more easily in solids and liquids because the particles are closer together than in gases because the particles are farther apart.

Good conductors are materials that allow electricity to easily pass through them. Bad conductors are materials that do not allow electricity to easily pass through them.

Most metals are thought to be good electrical current conductors. Copper is just one of the more common materials used in conductors. Silver, gold, and aluminum are other materials that are occasionally used as conductors.

Thus, the given statement is true.

Answer:

They are combined with oxygen and hydrogen ions to form water.

Explanation:

The electron released from the breakdown of glucose transfers in the electron transport chain and is used in the formation of a proton gradient across the membrane.

In the presence of oxygen gas, cells undergo cellular respiration, which is how energy from food is produced. The majority of plants, animals, birds, humans, and other mammals all engage in this sort of respiration regularly. As byproducts of this process, water and carbon dioxide are created.

The energy that was stored in carbohydrates and lipids during photosynthesis is released during the process of aerobic respiration and made available to living things. Glycolysis, the link reaction, the Krebs cycle, and oxidative phosphorylation are the four phases.

Protons are pushed out of the matrix and into the intermembrane space as a result of the electrons moving through the electron transport chain. The electrons eventually reach oxygen, which reacts with protons to create water.

Explanation:

Given what we know about the behavior of gases like helium, we can confirm that the small tank of helium was able to fill so many balloons because the helium expanded to fill its new container, which is the balloon.

Helium is a chemical element known as a noble gas. Like all other elements in a gaseous state, the atoms that comprise helium are spaced apart. This allows the gas to be compressed, a property that manufacturers of the gas take advantage of since they can compress a large amount of gas into a small container.

This is precisely what is happening in the question. The small tank of helium, despite being small in size, contains a large amount of compressed helium gas. Therefore, once it is released from the container, the gas expands to fill its new container, which in this case is the balloons, because of this, a relatively small tank of helium was able to fill many large balloons.

Answer:

Anything that is currently moving or giving off energy such as heat, light, or magnetism would be kinetic energy instead.

Explanation:

Things like objects on top of hills, unused batteries, chemicals that haven't been mixed, would all be examples of potential energy. Even steam is an example of potential energy since it has changed to a higher energy state. But as soon as steam does something, causes an injury (scalding), or starts to turn back into water, then it is kinetic energy.

Of course, to blur the lines a bit, something can have both forms of energy at the same time. If you push a cart down a hill, the movement is the kinetic energy, but until it reaches the bottom, then it also has potential energy in the form of gravity.

Kinetic energy and thermal energy are two non-examples of potential energy as they are forms of energy related to motion and particle movement, respectively, rather than stored energy.

Kinetic energy is not an example of potential energy as it is the energy of an object in motion, while thermal energy is also related to the random motion and vibrations of particles rather than stored energy based on position or configuration.

Kinetic Energy: Kinetic energy is the energy possessed by an object due to its motion

Thermal Energy: Thermal energy is the energy associated with the random motion of particles within a substance.

Thus, kinetic and potential energy are examples of non-potential energy.
