C. a Y chromosome from his father
This is because boys have one X and one Y chromosome, while girls have 2 X's, so the Y must come from the father.
Hope this helps :D
Answer:
True.
Explanation:
Enkephalins and endorphins are endogenous peptides while morphine is an exogenous peptide.
Enkephalins and endorphins are powerful analgesics 18 to 500 times more than morphine. Hence, morphine is less analgesic than enkephalins and endorphins.
Enkephalins and endorphins act on the mu, kappa , delta receptors and morphine also acts on the same receptors. All of them has same effects on the body.
Hence, Enkephalins and endorphins are peptides that act like morphine.
The kinetic energy of a car with a mass of 1,324 kilograms, traveling at a speed of 20 meters seconds is 264800J.
<h3>How to calculate kinetic energy?</h3>
The kinetic energy of a moving car can be calculated using the following formula:
K.E = ½ × m × v²
Where;
- K.E = kinetic energy
- m = mass
- v = velocity
K.E = ½ × 1324 × 20²
K.E = 264800J
Therefore, the kinetic energy of a car with a mass of 1,324 kilograms, traveling at a speed of 20 meters seconds is 264800J.

Translation is converting the mRNA code from DNA to functional proteins. The requirements for translation to occur is an mRNA strand in the cytoplasm from the nucleus, ribosomes, and tRNA containing a specific amino acid.
The first step is initiation where the ribosomal subunits attach to the mRNA strand then the tRNA will bind to the start codon (the mRNA sequence that signals the start of translation or AUG). The next step is the elongation phase where the subsequent codons are recognized and the respective amino acid from the tRNA is attached to the growing chain. Lastly, the termination phase where the growing amino acid chain will detach from the mRNA through the recognition of the stop codon (UAG, UGA, UAA).
Diffusion is defined as the movement of particles from higher concentration area to lower concentration areas. It continues until the concentration of substances is uniform throughout.
So, the best possible answer to this question is option A - when you inhale oxygen into your lungs,it is sent through your bloodstream to the rest of your body.
