Answer:
Animal cells (including humans ofcourse), heterotrophs, derive their energy from coupled oxidation-reduction reactions. Glucose is a primary fuel for heterotrophs. Energy derived from glucose is stored in the form of high-energy phosphate bonds in ATP, or other nucleotide triphosphates, and as energy-rich hydrogen atoms associated with the co-enzymes NADP and NAD .
Glucose is unable to diffuse across the cell membrane without the assistance of transporter proteins. At least 13 hexose transporter proteins with different functions have been identified. Some hexose transporters allow glucose to flow passively from high to low concentration without requiring the expenditure of cell energy. Those that move glucose against its concentration gradient consume energy, generally in the form of ATP.
D-Glucose is the natural form used by animal cells.
So yes it is present inside human cells .
They are known as evolutionary biologists. Strictly speaking, anthropology is split up into a number of disciplines - physical (sometimes known as biological) anthropology is the study of evolution as it relates to human beings. Further to this, scientists who study evolution in the fossil record are known as evolutionary palaeobiologists or simply palaeobiologists.

Answer:
A) Hummingbirds drinking nectar from a plant.
Step-by-step explanation:
Here are some examples of natural selection: In a habitat there are red bugs and green bugs. The birds prefer the taste of the red bugs, so soon there are many green bugs and few red bugs. The green bugs reproduce and make more green bugs and eventually there are no more red bugs.
