Heterotrophic. Only plants have cell walls, so that goes to phytoplankton, andwhales have thousands of cells, so unicellular goes to plankton again. Mammals aren't prokaryotic, so we're left with heterotrophic.
Phosphorus. It's not abundant, but it's important. There are traces of it in our bones and in the "phospho-lipid bilayer" of the membrane.
Hope that helps!
Increased importance of culture as an adaptive mechanism
Neolithic Revolution is known as the Agricultural Revolution where major changes were introduced and wide-scale transition of many human cultures from a lifestyle of hunting and gathering to one of agriculture and settlement, making an increasingly increased importance of culture as an adaptive mechanism
<h3>What are evolutionary changes ?</h3>
Heritable changes that occur through time in populations and species as a result of processes including sexual selection, random genetic drift, and natural selection.
- A population, a collection of interacting individuals of a single species, exhibits a change in allele frequency from one generation to the next due to five main processes. These include natural selection, non-random mating, gene flow, genetic drift, and mutation as forms of evolution

Answer:
Birds can keep themselves warn without any external heat source which is not the case with reptiles and amphibians
Explanation:
Birds are able to generate heat means they are endothermic. They generate heat through various metabolic processes. They have air pockets beneath their feathers to insulate their bodies during cold temperatures. Feathers which are modified reptilian scales help birds to streamline their exterior body and structure feathers in a way that it insulates the body.
Because comets are darker colored so they need light to shine on them to be seen in the dark skies of space.
