The decay of Francium produces radium-223 (Ra-223) through a beta decay or into astatine-219 through an alpha decay. The atomic number of Francium is 87, and that of Astatine is 85.
<h3>What is beta decay?</h3>
Beta decay is a type of radioactive decay in which a beta ray is emitted from the nucleus of an atom. During the beta decay, a proton in the nucleus is transformed into a neutron and vice versa which results into change in the number of proton in the nucleus. If a proton is converted to a neutron, then it is said to be β+ decay. And, if a neutron is converted to a proton, then it is said to be β– decay.
In this reaction, an atom of Francium (Fr-223) is undergoing a beta decay to produce radium (Ra-88) by the conversion of a neutron into a proton.

Answer:
the sun shines on earth, which through photosynthesis in a humble blade of grass turns into food and energy for the grass. now a small mouse hops along, stomach growling. it eats our blade of grass now itself getting energy. the naive, full mouse hops through the field before it squeaks in horror. a snake slinks towards it. the mouse is too slow. and the mouse breathes his last breath. the snake swallows it whole. stomach content now digesting its new energy sleeps. before it has the chance to react a hawk snatches it up in her claws. killing it she eats. this snake is poisonous, the next time our hawk flies, she stumbles, then falls. vanquished by poison her lifeless body lies in the dirt. her nutrients go into the soil, thanks to decomposers like worms. her nutrients help new grass blades grow, and the cycle continues.
I hope this helps u!
Pls give brainliest(had 40 down to 2 for no reason and worked long) and a thx ;)
I will thank u via profile thanks and comments
<span>the one that is not a source of genetic variation is : D. Asexual reproduction
In asexual reproduction, there is no fertilization process between male and female gender. Which mean the offspring that came from asexual reproduction would be exactly the same as its parent, without any chance of genetic variation</span>
