Write in your own words:
"Since the mouse is an endotherm, it probably has a higher metabolic rate, and thus a faster growth rate, than the lizard (an ectotherm of similar size) does. If the mouse has a faster growth rate, its bones would grow more between each ring, resulting in wider bone rings."
: )
and remember that a mouse is a endotherm because it generates metabolic heat to maintain internal body temperature.
Both the offspring (hybrid offspring) produced by donkeys and horses are infertile, sterile, cannot have its own offspring and both have 31 pairs of chromosomes each. Because of this, both horses and donkeys are considered as a separate species
The answer is b. Hope this helps!
Atomic number = number of proton = 16
Atomic mass = number of proton + number of neutron = 16+18 = 34
Net charge = Number of proton - number of electron = 16-13 = +3
OPTION A IS YOUR ANSWER....
