Answer:
C.) Chromosomes
Explanation:
Nucleotides are made up of three parts: a deoxyribose sugar, a phosphate, and a nitrogen base.
Chromosomes are long, condensed strands of DNA.
He is missing a (real) control. Growing two plants without plant food at all doesn't count; in order to see if the new food is better, he must also grow plants with the original food in order to compare it.
He does have an independent variable. This is the type of plant food. It's independent because he has direct control over it.
He needs to give plants the same conditions besides food: same water (amount), same light exposure, same temperature, etc.
He needs to choose a quantitative way to measure how much the plants grew, like mass or length.
A element mixture (key word: mixture) due to the mixture containing 2 different types of elements it can be said that it’s highly likely that the mixture was not a compound but instead of a mixture due to mixture meaning more than 1 material. Hopes this help!
Answer:
Explanation:
Hello.
In this case, we can solve this problem by applying the Boyle's law which allows us to understand the pressure-volume behavior as a directly proportional relationship:
In such away, knowing the both the initial pressure and volume and the final volume, we can compute the final pressure as shown below:
Consider that the given initial pressure is also equal to Pa:
Which stands for a pressure increase when volume decreases.

It doesn't take much energy to remove one electron from a sodium atom to form an Na+ ion with a filled-shell electron configuration. The first ionization energy of magnesium is larger than sodium because magnesium has one more proton in its nucleus to hold on to the electrons in the 3s orbital.
