Answer:
This question is incomplete as it lacks options, the options are:
A) What is the radius of each particle of the substance?
B) Does the substance contain more than one type of atom?
C) Was a chemical reaction necessary to create the substance?
D) What is the electrical charge of the particles of the substance?
The answer is B
Explanation:
In chemistry, an element is a substance made up of a single type of atom i.e. only one atom of the same type constitutes an element while a compound is a substance that contains two or more different elements. If a compound contains different elements, it means that a compound will certainly contain more than one type of atom.
According to this question, the best question to ask when Alyssa wants to differentiate between an element and a compound is: DOES THE SUBSTANCE CONTAIN MORE THAN ONE TYPE OF ATOM?
- If the answer is yes, the substance is a COMPOUND
- If the answer is no, the substance is an ELEMENT.
An organism has syncytial nuclei, which leads to parasynchronous or synchronous mitosis and therefore, multiple nuclei undergo the process of mitosis at the same time. This happens to the nuceli present in one cytoplasm, i.e., one cell.
Answer:
The tall parent was heterozygous
Explanation:
If tall height is dominant to short height the only genotype possible for short height is hh, while there are two possible genotypes for tall height, Hh and HH. When HH is crossed with hh all the offspring are Hh, but if Hh is crossed with hh, a quarter of the offspring is HH, a quarter is hh and half is Hh. If the tall pea plants were HH there would only be tall offspring, but because there are some short offspring we know that the tall pea plants must have a genotype of Hh.
