Explanation

Virus-infected cells and cells induced with other agents, e.g.,

double-stranded polynucleotides, can secrete proteins called interferons, which protect normal cells from viral infection

Explanation

Once the myosin-binding sites are exposed, and if sufficient ATP is present, myosin binds to actin to begin cross-bridge cycling.

Explanation

the given valence shell electronic configuration is 4s2 4p1.

This means that the atom has a total of 3 valence electrons, with 2 electrons in the 4s subshell and 1 electrons in the 4p subshell

2 + 1 = 3 (III-A)

would be in GroupIII-A and 3 period.

Explanation

There are there ions   Na^ +(Z = 11), Mg ^+2  (Z=12) and Al^ +3 (Z=13)

The number of shells is the same in all three ions such as 2 shells 

The number of electrons in all three ions is the same such as they are 10 e. So electronic configuration is also the same

The number of protons of these three ion is different due to different atomic number 

Atomic number (Z) = number of protons in the nucleus of an atom = number of electrons in a neutral atom.

atomic no. of Na is 11

atomic no. of Mg^+2 is 12

atomic no. of Al^+3 is 13

So option "D" is correct

Explanation

Explanation

The study of poison is called Toxicology.

Toxicology is a scientific discipline that deals with the study of the adverse effects of chemicals or substances on living organisms.

Including the detection, prevention, and treatment of poisoning.
