<h3>What is anatomy?</h3>
Anatomy is a branch of biology that is concerned with the study of the structure of living organisms and their various parts.
Anatomy studies the position of body structures as well as the position of related structures or organs of the body.
Anatomy also studies how the structure of these body parts relates to their functions.

Answer:
The limitation of phylogenetic species concept is b. Evolutionary histories are not known for all species.
Explanation:
The species that share a common ancestor and have similar traits and functions are grouped together as a result of the phylogenetic species concept. The phylogenetic species concept shows a unique evolutionary history of one organism with another of the same group. The major set back in the phylogenetic species concept is the lack of evolutionary histories for certain species. So, these organisms cannot be grouped according to the phylogenetic species concept.
<span> Location B, because it receives sunlight at a smaller angle than location</span>
Explanation:
Complete answer:
A mature erythrocyte lacks nucleus and mitochondria so as to make a place for the accommodation of more hemoglobin and hence more oxygen molecules. Lack of such organelles also provides the peculiar biconcave appearance of RBCs that aids in efficient diffusion. Young mammalian RBCs are nucleated.
