Answer: Acidification of the ocean
Explanation:
Human activities are increasing the amount of carbon dioxide in the environment. The harmful gases released from the automobiles and factories release huge amount of carbon dioxide into the atmosphere.
The carbon dioxide from the environment gets diffused into the ocean and leads to increase in the level of carbon in water.
Ocean acidification has destroyed the shells of aquatic animals and also leads to coral bleaching.
The Krebs cycle produces 2 ATP, 6 NADP, 2 FADP, and CO2, so I'd say carbon dioxide.
<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".
Genes<span> for medically important </span>proteins can<span> be cloned and inserted into </span>bacteria<span>, as shown in the diagram below. </span>Why can bacteria recognize a human gene and then produce a human protein<span>? A. DNA replication in </span>bacteria<span> and </span>humans<span> is the same. B. </span>Bacterial<span> cells contain the same organelles as </span>human<span> cells.</span>
