Biology

melomori [17]3 years ago

Answer:

Elements that are found in the same horizontal row (belong to the same period) in the periodic table, e.g. Fluorine and Neon both have the same energy level of 2.

<em>Note: The question does not specify any two elements.</em>

Explanation:

The modern periodic table is organized into eight vertical columns known as groups and seven horizontal rows known as periods. The atomic number ( number of protons in the nucleus) of elements increases when moving across the periodic table from left to right. The horizontal rows or periods represents an energy levels or the number of electron shells in an element. Energy levels (also called electron shells) are fixed distances from the nucleus of an atom where electrons may be found. Elements belonging to the same period have the same number of energy level or shells. For example, the elements belonging to Period 2 include lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine and neon. These all have the same number of energy level of 2.

Answer:

fast- flowing areas usually contain more oxygen than slow-flowing ones.

Explanation:

looking at the statement that accurately compares fast-flowing and slow-flowing areas of stream and water, we need to understand how they flow. a stream flow downhill and it can also flow in a perfect channel, except when flooding occurs and water overflows its channel and spread out across the area of the land. so, fast-flowing generally have higher levels of dissolved oxygen more than slow-flowing because slow-flowing are aerated.
