b. the axis has a slight tilt
Just because ONE chimpanzee used tools, doesn't mean ALL chimpanzees use tools. You need to observe way more than one chimpanzee to conclude that they ALL do that thing. For example, if I saw one monkey eating honey, I can't conclude that ALL monkeys eat honey.
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 .
Your answer is D. <span>There are almost no similarities between the genetic code of these four organisms, and are placed into four different kingdoms.</span>
They have nothing in common.
