Answer:
Explanation:
The lamp and the ice bag were at the same place.
Sounds like the experiment was intended to show on a small scale ocean currents from the poles to the equator and back to the poles. The bag of ice would simulate the cold at the poles while the lamp would simulate the heat provided by the sun near the equator. With that in mind, let's look at the possible flaws and see what is likely.
Not enough ink was added.
* If you can see the ink, then there's enough ink. So this isn't the correct choice.
Not enough water was taken.
* Possibility there wasn't enough volume of water to setup a current, but not too likely since the baking dish was filled. So let's look further.
The dish was too small for the experiment.
* Same as above. It might be this, but there's something more likely.
The lamp and the ice bag were at the same place.
* This sounds like a winner. In the real world, the poles are cold and the equator gets more sunlight. So there's a temperature gradient. In the described setup, both the heat sink (the bag of ice) and the heat source (the lamp) were at the same location.
Answer:
Tetracycline was discovered in the 1940s and is effective against both gram-positive and gram-negative bacteria. Tetracycline is an antibiotic which kills the bacteria by inhibiting the synthesis of protein.
Tetracycline act by inhibiting the process of translation by preventing the binding of aminoacyl-charged tRNA to the A site of the ribosome.
Since the aminoacyl charged tRNA does not bind the A site therefore the process of translation is inhibited.
Answer:
in DNA, Cytosine always forms hydrogen bonds with guanine

Although not completely proven, it's true some researchers suggest that consumption of large amounts of caffeine can result in cancers of the bladder, ovaries, colon, and kidneys.
<h3>How caffeine effect body ?</h3>
The body readily absorbs caffeine, and the short-term effects often manifest between five and thirty minutes after consumption. Increased breathing, heart rate, mental and physical vigor, as well as increased heart rate, are examples of these impacts. The duration of these effects varies from person to person and can reach 12 hours.
As little as 300 milligrams of caffeine, or about four cups of coffee, can raise your risk of experiencing adverse effects like nausea, anxiety, restlessness, and insomnia in adults. Caffeine misuse or excessive use in some individuals can also result in: Headaches. Irritability.
