It can rapidly increase if the environment is good for them
Hi there!
<u>Electronegativity</u> is the concept of how likely an atom is to attract the shared molecules in one of these bonds to itself. We know the molecule water is made up of two hydrogens and one oxygen. The electronegativity of hydrogen is 2.2, and oxygen 3.4. An <u>ionic bond</u> needs at least a difference in electronegativity of 1.6. As the difference is less than that, we can say that water is a covalent molecule. This then wipes out choice B, because it is not ionic, and C, as we have seen it is actually covalent.
Now, we can see the difference in electronegativity between oxygen and hydrogen is still 1.2. This means that while it is not at the point for there to be an ionic bond, there is still a difference in attraction, where the electrons will tend to favor the oxygen more and 'hang around it' more. As electrons are <u>negatively charged</u><em><u>,</u></em> this means that the oxygen will gain a slightly negative charge. This then makes the molecule polar, because it now has a charge within the molecule. This means we have our answer, choice D.
In terms of hydrophobic molecules - they tend to be ones without a charge. (If you're interested in this kind of stuff, I'd search hydrophobic up, and possibly also look into hydrogen bonds).
Hope this helps! Feel free to ask me any other questions you have about this specific problem.
It’s D. Carbohydrates are broken down and release ATP energy during cellular respiration.
I believe the answer is B. Carbon is NOT a macronutrient since <span>Nutrients are classified as macronutrients and micronutrients. </span>
The core of the adaptive success characterized by population explosion was the result of an increased food supply.
So, the correct option is (d).
- The main driver of adaptive success—the population explosion—was a rise in food availability. The main cereal grains domesticated during the early Holocene, namely wheat, barley, corn, and rice, account for two thirds of caloric intake.
- The availability of sufficient quantities and quality of food for human populations is known as food security. Global demand for food has increased as a result of the world's rapidly growing human population.
- The food supply chain is essential in ensuring that the food we eat gets to our lips without any problems. The world community needs this complex system to preserve the security, sustainability, and safety of food.
