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:
option c punctuated equilibrium
Explanation:
Punctuated equilibrium occurs in a process whereby evolutionary changes occurs in some organisms in a rapid burst of time rather the conceived gradual changes that occurs over a long period of time. this burst of time might be in about 500,000 years. It is assumed that the organism has maintained/lives in stasis for a long period without a need for change, but then, once the change takes place (most of the time, due to an environmental factor), the organism quickly adapts to its new environment with this new adaptation.
In short, raw material extraction and processing always impact on the environment, resulting as they do in soil degradation, water shortages, biodiversity loss, damage to ecosystem functions and global warming exacerbation. ... Products need energy and water, as well as land for shipping, marketing and use.
Sorry if I didn’t help
Anyways have a nice day / night! :)
Answer:
a sequence of DNA responsible for coding a protein = gene
The complex range of alleles an organism carries for... = genotype
an allele that determines... = dominant gene
the observable characteristics= phenotype
Answer:
D its population decreases
Explanation:
since a species cannot adapt they most probobly loose population
