The skeletal structures of both the bats and the humans developed from the same embryonic tissue for the main reason that both of these skeletal contains the humerus, radius, ulna, and the five digit bones. In addition, the main difference that these structures have is that the bat's wing is longer compared to the human arm.
Answer:
The question lacks options, the options are;
A) 4 KJ
B) 122 KJ
C) 30.5 KJ
D) 1600 KJ
The answer is B, 122KJ
Explanation:
Adenosine triphosphate (ATP) is the energy currency of all living cells. It is the usable form of energy by cells for their life functions. Energy in ATP is harnessed via the hydrolysis of one of its phosphate molecules to form Adenosine diphosphate (ADP). The energy (measured in Kilojoules) needed by cells is released in this process.
In this case, a cell uses energy to pump hormones into the bloodstream. According to the question, 4 ATP's were used i.e. 4 ATP were converted to ADP. The hydrolysis of one ATP molecule releases 30.5 KJ/mol of energy needed for cellular work.
Hence, if 4 ATP were utilized by this particular cell, 4 × 30.5 KJ = 122 KJ of energy will be used by the cell to pump hormones.
Answer:

I am pretty sure these are all right :D
Explanation:
non-metals gain electron and metals lose electrons,
<span>Iron is a metal, so when it reacts it loses an electron becomes a
cation and form ionic bonds. Hydrogen is a non-metal, it gains an electron when
reacting and forms covalent bonds or ionic bonds.</span>
