Analyze the following statements. Which of them is correct with respect to the RNA transcript formed by means of transcription?

1 answer:

8 0

The only statement which I find correct is definitely the second one : The RNA transcript is complimentary to the DNA from which it is transcribed. Instead of thymine, it has uracil, which complements the adenine of DNA; as you should remember that in in<span> RNA, U comes instead of T.</span>

Calculate the volume of 1 M NaOH needed to prepare 12.0 mL of a 0.10-M solution. Prepare this solution. (Refer to the Dilutions

Lapatulllka [165]

Answer:

1.2 mL

Explanation:

<em>This is a problem of simple dilution. The dilution principle simply agrees that the number of moles before dilution must be equal to the number of moles after dilution.</em>

Recall that: number of moles = mass/molar mass or molarity x volume.

Hence, for the dilution principle:

initial molarity x initial volume = final molarity x final volume.

In this case, initial molarity of NaOH = 1 M, initial volume = ?, final molarity = 0.1 M, final volume = 12.0 mL.

Initial volume = final molarity x final volume/initial molarity

= 0.1 x 12/1 = 1.2 mL

It thus means that 1.2 mL of 1 M NaOH would be taken and then diluted up to 12.0 mL mark by the addition of distilled water in order to produce 12.0 mL, 0.10 M NaOH solution.

The histogram shows the worldwide population densities of killer whales, or orcas, distributed by latitude. According to the gra

shutvik [7]

The correct answer is - Most killer whales congregate in the areas that are near the Arctic/Antarctic Circles.

The killer whales have a very large distribution, and they can be found in all oceans, apart from the Southern Ocean. It is noted though that the population density of the killer whales differs from place to place. The higher concentrations are found around the Arctic and Antarctic Circles, where there's cool rich waters, while in the lower latitudes they are much rarer. The reason for this probably lies in the fact that most of the animals that are considered to be the prime food source of the killer whales are living in this rich cold waters.

Assignment: 01.03 Transformation of Energy

trasher [3.6K]

The energy transformations that occur in the given devices are as follows:

Windmill - mechanical energy to electrical energy
Flashlight - electrical energy to light energy
Microwave - electrical energy to heat energy
Firecracker - chemical energy to heat, light, and sound energy
Bicycle - Chemical energy to mechanical energy
Battery - chemical energy to electrical energy

<h3>What is energy transformation?</h3>

Energy transformation refers to the processes by which one form of energy is transformed into another form.

The law of conservation of energy guides the various energy transformations that occur in the universe.

The law of conservation of energy states that energy is neither created nor destroyed but can be transformed from one form to another.

The energy transformations that occur in the given device are as follows:

Windmill - mechanical energy to electrical energy
Flashlight - electrical energy to light energy
Microwave - electrical energy to heat energy
Firecracker - chemical energy to heat, light, and sound energy
Bicycle - Chemical energy to mechanical energy
Battery - chemical energy to electrical energy

In conclusion, energy transformations occur according to the law of conservation of energy.
