Answer:
Gametes
Explanation:
Gametes are an example of a haploid cell and are produced as a result of meiosis.
Answer:
The correct answer is option (D) "His- strain grows on an his- plate".
Explanation:
The Ames test is a procedure that allows to detect if a given compound can cause mutations on a tested organism by growing strains of bacteria that require histidine (His-) to growth, since they are not able to produce its own histidine. In the Ames test, the bacteria is exposed to a given compound and is grown in a medium with small amount of histidine (his- plate). If the His- strain grows on a his- plate, it means that the bacteria has mutated to synthesize its own histidine and it is considered as a positive result on a the Ames test.
The priority after administering is to assess fetal heart
rate. After administering an opioid to a laboring mother, the main concern is
to evaluate the effect on the fetus. Opioid administration can cross the
placental obstruction with signs as well as measuring heart rate and
variability. Subsequently after birth, there may be a reduction in attentiveness.
Maternal factors of a reduced blood pressure, constipation and dry month are of
a lesser importance.
<span>Answer: Opening of Na+ and K+
Explanation:
Acetycholine binding opens Na+ and K+ ion channels in the receptors that allow simultaneous passage of Naâş into the muscle fiber and Kâş out of the muscle fiber. More Naâş ions enter than Kâş ions exit, which produces a local change in the membrane potential called the end plate potential.
Binding of acetycholine to receptor proteins opens Na+ and K+ channels resulting in jump in resting membrane potential(RMP) from -90mV to +75mV forming an end-plate potential (EPP).</span>
