If a FRAMESHIFT mutation causes a stop codon to be inserted into the DNA sequence
Answer:
The frameshift mutation will also alter the first stop codon ("UAA", "UGA" or "UAG") encountered in the sequence. The polypeptide being created could be abnormally short or abnormally long, and will most likely not be functional.

what work is done when a person pushes a refrigerator across the floor 12m using 480N of force ?
Answer:
W = 5760 J
Explanation:
Force (F) = 480 N Distance (d) = 12 m Work (W) = ?Use the formula:
W = F * dReplace with the data, and solve:
W = 480 N * 12 mW = 5760 JThe work done was 5760 Joules.

Describe how energy is transferred from 1 form to another
Answer:
Thermal energy may be transferred in three ways: conduction, convection, and radiation. Conduction occurs when heat energy is exchanged between nearby molecules that are in touch with one another.

Explain this phase diagram by relating what you know about temperature, states of matter and
pressure.
Answer:
See explanation
Explanation:
The vertical axis corresponds to the pressure of a substance, while the horizontal axis corresponds to the temperature. The solid is the substance which contains particles of strong intermolecular force and compaction, typically ionic at a certain temperature, the liquid is the substance which contains relatively compact molecules, however lacks a particular arrangement. The gaseous substance is caused by particles with weak intermolecular forces, causing particle movement and collision with no arrangement whatsoever. The triple point as shown in the diagram, is the phrase on a diagram where each substance: solid, liquid and gas coexist. The critical point is the phase at which the/a substance is indistinguishable between liquid and gaseous states. A substance or elements state is highly dependent on its environment and it’s temperature, of which ultimately affects its kinetic energy within its particles. This is what the graph portrays and represents.

Gravitational potential energy is just one type of stored energy.
t or f??
Answer: true because potential energy is stored in a object
Explanation:
difference between horizontal and vertical motions
Answer:
This is to say that the vertical velocity changes by 9.8 m/s each second and the horizontal velocity never changes. This is indeed consistent with the fact that there is a vertical force acting upon a projectile but no horizontal force.

how can you reduce the percentage uncertainty in measurements that you make?
can you predict a dark room is empty or not with the help of sound? how?
please help me ।
50 points
Answer:
Sound waves can reflect off surfaces. We hear sound reflections as echoes. Hard, smooth surfaces are particularly good at reflecting sound. This is why empty rooms produce lots of echoes.
Soft, rough surfaces are good at absorbing sound. This is why rooms with carpets and curtains do not usually produce lots of echoes.
Explanation:
With this information, you'd be able to come up with your answer,

Explain why the coin is able to float on top of the water in this glass.
Answer:
Surface tension is the result of water molecules pulling inward with a strong attractive force. This attractive force brings the molecules on the surface of the water close together and causes the surface of the water to be drawn toward the water molecules beneath the surface. Since there are no water molecules above the surface, there are uneven forces. This causes surface tension, allowing the coin to float on the water’s surface.

An automobile travels the first half of an 80.0 mi trip at 20.0 mi/h and the second half of the trip at 40.0 mi/h. What is the average speed for the entire trip?
This question involves the concepts of uniform speed motion and average speed.
The average speed for the entire trip is "26.67 mi/h".
First, we need to find out the total time taken for the entire trip. For that purpose, we will break the entire trip into two halves of uniform speed motion:
[tex]Total\ Time = t_1+t_2\\\\Total\ Time = \frac{s_1}{v_1}+\frac{s_2}{v_2}\\\\Total\ Time = \frac{40\ mi}{20\ mi/h}+\frac{40\ mi}{40\ mi/h}\\\\Total\ Time = 2\ h + 1\ h\\Total\ Time = 3\ h[/tex]
Now, the average speed for the entire trip will be:
[tex]Average\ Speed = \frac{Total\ Distance}{Total\ Time}\\\\Average\ Speed =\frac{80\ mi}{3\ h}[/tex]
Average Speed = 26.67 mi/h
