Some plants can reproduce both sexually and asexually. Explain one benefit of this dual reproduction capability.
pantera1 [17]

Answer:

An additional advantage of asexual reproduction is that colonization of new habitats may be easier when an individual does not need to find a mate to reproduce. During sexual reproduction the genetic material of two individuals is combined to produce genetically diverse offspring that differ from their parents.

Explanation:

An organism has many benefits for having the ability to reproduce both sexually and asexually. The first of these benefits is that it doesn't have to find a mate in order to reproduce, so it can create offspring by itself, and enable the continuation of its' species.

A sample of fluorine contains isotopes with different masses; F-19 and F-18. In the sample 94% of the
zalisa [80]

The relative mass of the sample : 18.94

<h3>Further explanation </h3>

The elements in nature have several types of isotopes

Isotopes are atoms whose no-atom has the same number of protons while still having a different number of neutrons.

So Isotopes are elements that have the same Atomic Number (Proton)

Atomic mass is the average atomic mass of all its isotopes

Mass atom X = mass isotope 1 . % + mass isotope 2.%

F-19 = 94% of the sample

F-18 = 100%-94%=6% of the sample

The relative mass :

\tt = 0.94\times 19+0.06\times 18\\\\=18.94
