The smallest functional and structural unit of an organism, usually microscopic and consisting of cytoplasm and a nucleus in a membrane.
Answer:
More electronegative
Explanation:
The oxygen and nitrogen in ammonia shows that they are more electronegative than the hydrogen atoms.
- Electronegativity shows the affinity of an atom for valence electrons.
- Electronegativity is the measure of the relative tendency with which the atoms of the element attract valence electrons in a chemical bond.
The oxygen atom in water and the nitrogen atom in ammonia are more electronegative.
They attract the electrons more and they then become negatively charged.
The hydrogen will then become positively charged in the shared covalency.

are true and in a correct order are Gravitational force held the newly formed
planets around the sun; small planetary objects formed; hydrogen and helium

Answer:
D. How frequently do earthquakes occur in San Francisco?
By studying the fossil record we can tell how long life has existed on Earth, and how different plants and animals are related to each other. Often we can work out how and where they lived, and use this information to find out about ancient environments. Fossils can tell us a lot about the past.
