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.

Composition of cell wall
:
Cell wall of bacteria is composed of carbohydrates protein complex known as peptidoglycan
.
Presence of organelles
:
Bacterial cells lack all organelles except ribosomes
Presence of fatty acids in plasma membrane
The plasma membrane of bacterial cell is composed of a lipid bilayer made up of phospholipid. It contains fatty acids
Conclusion

Muslces have many subsidaries. First its starts with the tendon leading to the whole muscle and the surrounding epimysium, then perimysium, then the muscle fibres. then they further break down into myotubes.
Answer:
The correct option is A. they evolved from land mammals.
Explanation:
Evolution can be described as a process through which organisms in a species change over a period of time due to the natural selection of the environment. Those organisms that have many similarities in their functions or structures are considered closer to one another and have the same common ancestors.
The properties mentioned in the question about cetaceans resembles the properties of land mammals. For example, cetaceans lack gills and breathe air. Land mammals also do not have gills and need to respire for living. The cetaceans have fin bones which are similar to the limb bones in the land mammals. Hence, these observations show that cetaceas have evolved from land mammals.
