Answer:
Genetic modification
Explanation:
a desired trait from one organism is placed into that of another organism with human intervention.
Answer:
2.64gram
Explanation:
Molarity, which refers to the molar concentration, is calculated thus:
Molarity = number of moles (n) ÷ volume (L)
According to the question, volume = 100 mL, molarity = 0.240 M.
Since 1L = 1000mL
100 mL = 100/1000
= 0.1L
Hence;
0.240 = n/0.1
n = 0.1 × 0.240
n = 0.024mol
Mole = mass/molar mass
Molar mass of CaCl2 = 40 + 35.5(2)
= 40 + 71
= 111g/mol
mass = molar mass × mole
mass = 110 × 0.024
Mass = 2.64gram
That makes the Earth, the Sun, and the rest of the solar system

P has five electrons, three available to share. Since Cl has seven valence electrons, it can take on one more to accomplish an octet. In PCl3, P’s three valence electrons are evenly distributed among the three chlorine atoms. Whereas, in PCl5 there will be two electrons left over, which is why it is an exception to the octet rule.
