Explanation:
(1) Is referring to Newton's first law, an external force (gravitational force) is applied to frogs motion, thus causing it to deviate from a straight line
(2) is referring to Newton's third law of motion, the action force is done by the ball hitting the ground and the direction is downwards, the reaction force is done by the ground transferring that same force to the ball, acting upwards
(3) I think it's also the first law, the person on a train is showing, the force to keep it at rest, the sudden halt of the train causes a reaction force to act on the person, does making the person move
(4) I think it's both Newton's second law and third law motion.
I hope these helps
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;
D. identical, diverse
Daughter cells produced when cells undergo mitosis are genetically identical, and daughter cells produced when cells undergo meiosis are genetically diverse.
Explanation;
Meiosis and mitosis are the two major types of cell division. Mitosis takes place in the somatic cells (body cells) in which parent cells undergo division to yield daughter cells that have similar number of chromosomes as the parents. Meaning the daughter cells are identical to the parent cells in terms of genetic material composition.
Meiosis on the other hand, involves division in the germ-line cells in which parent cells divides to yield daughter cells that contain half the number of chromosomes as the parent, meaning that they are not genetically identical, however they re genetically diverse due to the process of crossover and recombination.
