<span>1. List five observations Darwin made about the Amblyrhynchus lizards.

a. They measure about 2-3 feet long.
b. They are cold-blooded.
c. They feed on crab and sea lion feces.
d. They are the only marine iguanas in the world.
e. Their nostrils are connected to salt glands that allow them to expel excess sea salt. 

</span><span>2. Describe two examples of structural adaptations that Darwin observed.

a. </span><span>Darwin discovered that finches in the Galapagos have thirteen different kinds of beaks. 
b. </span>Darwin observed two kinds of giant tortoises that are distinguished by the shapes of their carapaces (dome-shaped and saddle-shaped). 

3. <span>Describe two behavioral adaptations that Darwin observed.
</span>
a. <span>The marine iguanas have developed several ways of coping with the cold. At night, they huddle together for warmth. 
b. </span>In the face of famine, the marine iguanas have adapted by having the ability to shrink their body size. They are able to grow back to their original size once the food is supply increases.

4. <span>Explain how these observations influenced his theory of evolution?
</span>

These observations led Darwin to believe that if a certain trait is more advantageous in a specific environment, then the carriers of that trait are more likely to survive into adulthood and to generate offspring than those who do not have that trait. Eventually, the advantageous traits for a species will proliferate. Darwin later called this as "survival of the fittest".

Why is pyruvic acid never the end product of fermentation
Igoryamba

Answer:

Pyruvic acid is not the end product of fermentation because in fermentation the pyruvic acid is converted into alcohol/lactic acid and carbon dioxide. There are two types of fermentation alcoholic fermentation and lactic acid fermentation.

In alcoholic fermentation, pyruvate is converted into ethanol and CO2 for example in yeast and in lactic acid fermentation pyruvate is converted into lactic acid and CO2 for example in animals muscles.

Therefore in fermentation pyruvic acid is not the end product of fermentation. In fermentation 2 ATP is produced.

describe the basic process of evolution by natural selection. Describe the underlying genetic basis and role of the environment
tankabanditka [31]

If an atom has twelve electrons, how many electrons are in the n=1 energy level? how many electrons are in the n=2 energy level?
Serjik [45]

Magnesium has 12 electrons.........which wud mean that in the 1st energy level(n=1) there r 2 electrons, in the 2nd energy level(n=2) there r 8 electrons and in the 3rd energy level(n=3) there r 2 electrons.......its simple......use the formula 2n^2 where n= 1,2,3,......  

so the electron configuration of Magnesium in 2,8,2..................or more precisely 1s2, 2s2, 2p6, 3s2

How does an r group determine if an amino acid is acidic basic or nonpolar?
Alinara [238K]
<span>R group (or side chain) is an organic component of amino acids that is unique to each amino acid. </span> <span>Three of the amino acids have basic side chains at neutral pH: arginine (Arg), lysine (Lys), and histidine (His). Their side chains contain nitrogen and resemble ammonia, which is a base and their pKa's are high enough that they tend to bind protons, (positive charge). Aspartic acid or aspartate (Asp) and glutamic acid or glutamate (Glu) are acidic amino acids because their side chains have carboxylic acid groups whose pKa's are low enough to lose protons, (negatively charged). The non-polar amino acids contain uncharged functional groups<span> at physiological pH and are incapable of participating in hydrogen bonding. </span></span>
