Answer:

B. binds to the tryptophan repressor when the repressor is bound to tryptophan.

Explanation:

Bacterial genes are commonly composed of operons that are activated or deactivated depends on the needed. If the bacteria need, for example, an amino acid such as tryptophan for synthesizing proteins. An activator "turns on" the transcription that the operon has and produces the amino acid.

On the other hand, if the bacteria have a high presence of tryptophan amino acid, a repressor binds to the tryptophan operator and avoids the amino acid transcription, in consequence, constrain the tryptophan production.

What is the importance of the electrons?<br> (write in one paragraph)
My name is Ann [436]
Well in everything we have protons and electrons, eg. In static electrisity in a balloon when you rub the balloon on a material like your hair all the protons come off and into your hair which makes your hair go upright and funny and the ballon is desperate to get back the protons so it sticks to surfaces to gain there protons to ballance out the electrons it allready has for it to be nuteral again. Because its important for everything that can be to be nuteral

Due to the low specific heat capacity of water the temperature of water changes much more quickly than the temperature of
Sholpan [36]

This statement is <u>TRUE.</u>

Explanation:

Due to the high heat capacity of water, it takes much more energy to have a gram of water raised by one degree compared to one gram of land. This is why during a hot day, the ground gets hotter faster than the adjacent oceans or adjacent lakes. It also takes water to lose the same amount of energy to have its temperatures drop by one degree as compared to land. During the night, therefore, this is why adjacent water bodies remain relatively warmer than land.

A car travels 75 mi/hr. How many hours will it take to travel 837 km? (Pick the answer closest to the correct answer,
nlexa [21]

Answer:

6.9 hours

Explanation:

In order to solve this problem we'll<u> convert 837 km to miles</u> (another option would be to convert 75 mi/hr to km/hr). To make said conversion we'll use the given <em>conversion factor</em>:

  • 837 km * \frac{1mi}{1.61km} = 519.88 mi

Finally we <u>calculate the time required to travel said distance</u> at a constant speed of 75 mi/hr:

  • 519.88 mi ÷ 75 mi/hr = 6.9 hr
