A, b, and c are all correct.
take for example finches off of the galapagos islands. they vary from island to island, yet are still the same bird. on one island they have bigger, more durable and stronger beaks, because that island has many nuts to crack open and eat. on another island, they have thin ling beaks, ideal for pecking at insects in the grass on tree bark. evolution is literally survival of the ifttest, where those equipped best will live and those without means to fight for life will die off, leaving those most capable of reproduction and passing down genes.
Cation. Sodium has 10 electrons with 1 outer valence electron, and outer valence electrons are positive. This means that it will have a charge of +1, and a cation is a positively charged ion that is attracted to the cathode during electrolysis, which is the decomposition (chemically) of something that happens after an electric current passes through it.
Answer:
Tundra
Explanation:
Permafrost is a layer just beneath the surface of the ground that never thaws.
Gametes of the parents would be:
PpTt : PT ; Pt ; pT ; pt
Pptt : Pt ; Pt; pt ; pt
You can do this easily using the FOIL method on each genotype. Just like in math, F stands for first; O stands for outside; I stands for inside; and L stands for last. I'll do one parent genotype and maybe you will understand how this was done:
GENOTYPE: <em>PpTt</em>
<em>F- </em><em>irst of each pair. P and T</em>
P p T t
Gamete: <em>PT</em>
<em>O </em><em>- utside allele of the pair. P and t</em>
P p T t
Gamete: Pt
<em>I - </em><em>inside alleles of the pair. p and T</em>
P p T t
Gamete: pT
<em>L</em><em>-ast or end allele of each pair. p and t</em>
P p T t
Gamete: pt
