It would have 18. Because using logic no one was born with only half of their chromosomes. When you think about it, Plant reproduction is basically like human reproduction. Hope i could help
Both abiotic and biotic factors determine both where an organism can live and how much a population can grow. A limiting factor is a factor that restricts the size of a population from reaching its full potential
The amount of food & water in a habitat is an example of a limiting factor. Other factors include geographical space, predation, climate, competition (for prey, food, mates) etc. An example of a limiting factor is sunlight in the rainforest, where growth is limited to all plants in the understory unless more light becomes available. Or perhaps in a deciduous forest, there are not enough rabbits to support the growth of more foxes. All species within an ecosystem will experience some kind of limiting factors to prevent continuous and exponential growth. (Even humans) Environmental changes (i.e drought, famine, human destruction) results in decreased rates of physiological processes, lowering the potential for survival, growth, or reproduction. Species will undergo Acclimatization to adjust to the new limiting factors through changing their behavior or physiology.
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.
