RNA polymerase can't bind on the promoter region, so no transcription takes place, consequently, no protein translation.

How does DNA make protein?

When a cell makes a protein the instructions are copied from part of the DNA strand and transcribed to new molecule, called RNA. RNA molecules carry the instruction from the nucleus to ribosomes.

Explain Mercury is the planet closest to the Sun. Why does it get so cold at night?
alexdok [17]

Answer/Explanation: On Mercury temperatures can get as hot as 430 degrees Celsius during the day and as cold as -180 degrees Celsius at night.

Mercury is the planet in our solar system that sits closest to the sun. The distance between Mercury and the sun ranges from 46 million kilometers to 69.8 million kilometers. The earth sits at a comfy 150 million kilometers. This is one reason why it gets so hot on Mercury during the day.

The other reason is that Mercury has a very thin and unstable atmosphere. At a size about a third of the earth and with a mass (what we on earth see as ‘weight’) that is 0.05 times as much as the earth, Mercury just doesn’t have the gravity to keep gases trapped around it, creating an atmosphere. Due to the high temperature, solar winds, and the low gravity (about a third of earth’s gravity), gases keep escaping the planet, quite literally just blowing away.

Atmospheres can trap heat, that’s why it can still be nice and warm at night here on earth.

Mercury’s atmosphere is too thin, unstable and close to the sun to make any notable difference in the temperature.

Space is cold. Space is very cold. So cold in fact, that it can almost reach absolute zero, the point where molecules stop moving (and they always move). In space, the coldest temperature you can get is 2.7 Kelvin, about -270 degrees Celsius.

Sunlight reflected from other planets and moons, gases that move through space, the very thin atmosphere and the surface of Mercury itself are the main reasons that temperatures on Mercury don’t get lower than about -180 °C at night.

Nataly_w [17]

The answer is benedict’s reagent.  Benedict’s test is used to detect reducing sugars in solution when heated. The color change occurs from clear blue to a brick-red precipitate in the presence of the reducing sugars. The cupric compounds in the benedicts reagent react with the reducing sugars (enediols) produced from heating of the reducing sugars in the presence of an alkali. Benedict's reagent is comprised of a mixture of sodium citrate, sodium carbonate, and copper(II) sulfate pentahydrate.

What type of energy is transferred during heating? a. thermal b. convective c. conductive d. temperate
Katena32 [7]

Thermal energy is transferred during heating.

What is thermal energy?

  • Thermal energy refers to the ability to do work. As such thermal energy can also be defined as the ability of something to do work as a result of the movement of its particles.
  • In other words, thermal energy is the energy possessed by an object or body by virtue of the movement of its constituent particles.
  • It is the total internal kinetic energy of an object due to the random motion of its atoms and molecules.
  • Thermal energy is a type of kinetic energy owing to the fact that it results from the movement of particles. Kinetic energy is the energy possessed by an object due to its motion.
  • Thermal energy forms the foundation of the study of heat energy and thermodynamics. It is one of the oldest forms of energy utilized by mankind.
  • Its usage existed even before petroleum and nuclear power sources were discovered.
