Answer:

True

Explanation:

Heat energy is the most easily dissipated form of energy. Light energy is frequently energy seen in combustion, and is a type of wave motion. Sound energy is another type of wave motion caused by the vibration of molecules in the air. Like heat energy, sound is a type of energy that is generally lost.

Plz help!! List 3 ways that scientists and engineers develop, use, and refine models

julia-pushkina [17]

These are some ways how scientists and engineers develop, use and refine models.

1. Imagine. They have to know what exactly trying to model. They have to imagine and brainstorm what are the things to be considered.

2. Reason. Next, they need to answer the questions brought from their brainstorming. They need to be able to reason out.

3. Calculate and Predict. Once they know it, that's the time they can start modelling and calculate - and predict.

Describe at least 2 patterns you notice about objects in the solar system using the model provided. (the solar system)

Lelechka [254]

1st pattern

Planets like, mercury, venus earth: they are in the increasing order of there masses. however this chain breaks at mars.

2nd pattern

Planets like, jupiter, saturn, uranus, neptune are arranged in decreasing order of there masses.

Really don't know that my explanation even any sense but have just tried.

Irina18 [472]

Answer:

The answer for this statement is "True".

Explanation:

In the kidneys, the countercurrent mechanism involves the interaction between the flow of filtrate through the loop of Henle of the juxtamedullary nephrons (the countercurrent multiplier) and the flow of blood through the limbs of adjacent blood vessels (the countercurrent exchanger). This relationship establishes and maintains an osmotic gradient extending from the cortex through the depths of the medulla that allows the kidneys to vary urine concentration dramatically which is true.

You are involved in an experiment involving fluorescent painting of chromosomes. You observe the following in a nucleus experien

Galina-37 [17]

Answer:

It seems that a reciprocal translocation is going on.

Explanation:

A translocation occurs when a chromosomal fragment changes its location in the same chromosome from the original to a new one. Or when it leaves the chromosome to re-locate in a new different chromosome.

According to this, there are different types of translocations:

Intrachromosomal translocations:

Intra-radial: the change in position occurs in the same arm of the chromosome. For instance, 123.456789 → 123.478569
Extra-radial: The change in position occurs from one arm to the other of the same chromosome. For instance, 123.456789 → 15623.4789

Extrachromosomal translocations:

Transposition: not reciprocal interchange. The fragment leaves a chromosome to re-locate in another chromosome. The other chromosome does not send any fragment to the first one.
Reciprocal translocation: There is a reciprocal interchange. A fragment of chromosome A goes to B, and a fragment of chromosome B goes to A.

Reciprocal translocations might be:

Fraternal: the interchange occurs among homologous chromosomes
External: the interchange occurs among non-homologous chromosomes

Reciprocal translocations are easily recognized during meiosis because an association between four chromosomes can be observed. This association is a quadrivalent structure.

During metaphase 1, the centromeres involved in the quadrivalent originate centromeric co-orientation or disjunction.
