Without variation in traits among the population, there would be no variation in the relative fitness of individuals within the population (i.e. (higher level) no differential reproductive success between individuals). Without varying reproductive success between individuals in population based on traits, there will be no change in frequency of traits in the population over time. To put it simply, there is nothing for natural selection to act upon.
Answer:
ionic
Explanation:
Ionic bond:
It is the bond which is formed by the transfer of electron from one atom to the atom of another element.
Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.
For example:
Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion.
There are one valance electron in sodium so it needed to lose one valance electrons to complete the octet while chlorine needed one electron to complete the octet. Thus electrons lost by sodium atom is gained by atom of chlorine and form ionic compound.
2Na + Cl₂ → 2NaCl
Answer:
plants, animals, microorganism and bacteria
Explanation:
Answer: The correct answer is A) fewer landfills.
When plastics and paper products are dumped in the landfills, they can cause harmful impacts to the wildlife. This is because chemicals like ammonia and bleach ( present in the landfills) can produce toxic gases and when wildlife tries to consume them, this can harm their health.
If paper and plastics are recycled, it will result in fewer landfills.
<span>The nurse's priority is to assess the patient, including vital signs. If the nurse detects that the labor is progressing, she should notify the physician. She should also determine whether the patient is due for pain medication and determine what she is able to give at that time period.</span>
