D.) It cannot be broken down into a simple substance through chemical means...
Answer:
It could pollute other planets. Nuclear waste might be attracted by the gravitational pull of the sun and disintegrate there instead. The waste storage spacecraft could crash into a planet, moon, or another astronomical body. It could be dangerous for other life forms out there.
Explanation:
Answer:
Gains
Explanation:
If it gains an electron it causes the atom to become negative since electrons are negative and an overall charge of an atom is neutral. Therefore, it would become negative.
Hope this helps :)
Answer:
5 electrons
Explanation:
Valence electrons are electrons located in the outermost energy shell, so you want to count the number of electrons in the last energy shell.
You can divide the configuration into 1s2 / 2s22p6 / 3s23p3 to see the energy shells in this atom. There are 3 shells occupied by the atom's electrons, so you need to count the electrons in the third shell as those are its valence electrons.
2 + 3 = 5 valence electrons total
Note: you don't count the 3 before the letter because that only indicates the shell level, not the number of electrons. Count only the exponents.
Answer:
Phenotype is : The actual appearance or characteristics of an individual organism (i.e the effect of allele combination ).
Explanation:
We come across differences shown by individuals of same species or we can say dis-similarity shown by offspring when compared to his/her parents .
When we cross parental generation , the gamete formation occur in accordance with Law of Segregation and then we get to see different combination of gametes that give rise to offspring with contrasting characters (In accordance with Law of independent assortment ).
After crossing we make conclusions by calculating the phenotypic and genotypic ratio of the cross .
Phenotype : It refers to physical expression of an organism or The actual appearance or characteristics of an individual organism (i.e the effect of allele combination ).
Phenotypic ratio of Monohybrid cross is always 3:1 .
Genotype : Refers to genetic constitution of an organism .
Genotypic ratio of Monohybrid cross is always 1:2:1 .
