<span>The epidermis is mainly a composition of cells called keratinocytes. Defensive cells are known as Langerhans cells and are one of the three types of specialized epidermal cells, The epidermis is bonded to the dermis. Hairs grow in the dermis and up to the epidermis. So, the dermis and the epidermis both have cells and hair. </span>
Answer:
all of them except the organelles as they don't have organelles
only some are multicellular too so E looks a bit suspect
Explanation:
Answer:
Natural selection
Explanation:
Natural populations have variations. Organisms of a population have various genetic traits. Some of these genetic variations make the organisms better suited to the prevailing environmental conditions. These organisms are more likely to produce more progeny. Over generations, the frequency of the beneficial genetic traits increases in the population due to the higher reproductive success of the organisms with these genetic traits.
This process of differential fitness of organisms of a population where the organisms with adaptive genetic traits have survival and reproductive benefits is called natural selection.
So the the main forces that keep the water on the surface of the planet are to do with plate tectonics. If the plates were to stop moving, the water probably would eventually be absorbed into the interior, although this process would take a very long time indeed.
