Answer:

There could be several possible reasons for a small gap between rails on a railway track, such as:

1. Expansion joints: Railways are designed to allow the tracks to expand and contract with changes in temperature. To accommodate this expansion, small gaps are left between the rail ends and filled with expansion joints or plates.

2. Wear and tear: Over time, the rails may experience wear and tear due to heavy loads, weather conditions, and other factors. As a result, small gaps can appear between the rails.

3. Maintenance: During maintenance activities, rail tracks may be adjusted or replaced, which could lead to small gaps between the rails.

4. Environmental factors: Environmental factors such as soil shifts, earthquakes or other natural disasters can also affect the alignment of the rails, leading to small gaps.

These are some of the possible reasons for a small gap between the rails on a railway track.

Answer:

The small gap left between the rails in a railway track is intentional and serves a specific purpose. This gap is known as the rail joint, and it allows for the expansion and contraction of the rails due to changes in temperature. When the temperature changes, the metal rails will expand or contract, and if they were joined together tightly, they could buckle or become deformed, which could be dangerous for trains passing over them. The rail joint allows the rails to move slightly and prevent damage to the track.

Additionally, the rail joint also allows for maintenance and repairs of the track. If there were no gap between the rails, it would be challenging to replace a damaged rail or perform routine maintenance, such as tightening bolts or lubricating joints. With the rail joint, maintenance personnel can easily access and work on the track.

Overall, the small gap left between the rails in a railway track is intentional and serves a crucial function in ensuring the safety and reliability of the track.

Answer:

observations (2), (3), and (4) provide strong evidence that a chemical reaction occurred.

Explanation:

Observations (2), (3), and (4) are evidence of a chemical reaction because a precipitate formed, energy was released (the bottom of the beaker felt warm), and bubbles were formed in the water. Observation (1) indicates a physical change, not a chemical reaction.

Carbonated beverage contains dissolved carbon dioxide and water, out of which water is solvent and carbon dioxide is solute and other sweeteners are also solute.

Solution is a homogeneous mixture which contain two component that are solute and solvent . Solute is the amount of component which is in small amount whereas solvent is a component which is  in large amount

Example: If we take sugar solution then the amount of sugar is small that is solute whereas water is in large quantity which is solvent. It is not necessary that water will be always solvent or liquid will be solvent, solid  and gas can be the solvent too.

In a solution of a carbonated beverage, water is solvent and carbon dioxide gas is the solute as it is dissolved in water. Thus carbon dioxide is solute in carbonated beverage.

Answer:

Explanation:  Mechanical energy is energy associated with the motion and position of an object. When you strike a match, it moves through the air until it rubs against a surface. The rubbing produces the heat required to light the match. This is a transformation from mechanical energy to thermal (heat) energy.

Genes with alleles IA, IB and I are responsible for expression of A B and O blood types= Multiple alleles

A red flower and a white flower produce

an offspring with equal proportions of red

and white coloration= Codominace

Explanation:

Took quiz and got it right

A pink roses are formed when red roses are mated with white roses shows  incomplete dominance.

Incomplete dominance is defined as the dominance occurs from a cross in which each parental contribution is genetically distinct and produces children with an intermediate phenotype.

Semi-dominance and partial dominance are other terms for incomplete dominance.

Genes with the alleles IA, IB, and I are responsible for expression of A, B, and O blood types shows multiple alleles.

A red flower and a white flower produce an offspring with equal proportions of red and white coloration shows codominance.

Why is the use of the inquiry process (or scientific method) a practical way to approach science?

1. The inquiry process is a practical way to approach science because the inquiry process begins by asking questions and moving on from there.  

2. In science it is important to investigate phenomena or certain subjects by posing questions that you would like to answer through the scientific method.

3.  Therefore, the inquiry method is connected because to inquire on a subject requires raising questions which is an essential step in scientific discovery.

Why are scientific theories modified, but seldom discarded?

1.  If a theory cannot explain new evidence or observations then the theory is revised or even thrown

out, but if the theory still explains a wide range of observations and evidence then it is revised

rather than discarded.

2.  it will still hold some value as above as you learn more you tweak your hypothesis to fit the ever expanding amount of info and data you collect and assimilate

3.  The only way they ever go away is if people stop working on them.
