Answer: The nucleus (plural, nuclei) houses the cell's genetic material, or DNA, and is also the site of synthesis for ribosomes, the cellular machines that assemble proteins. Inside the nucleus, chromatin (DNA wrapped around proteins, described further below) is stored in a gel-like substance called nucleoplasm. hopes this helps pls pls pls give me brainliest.
Explanation:
<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".
Answer:
2 ATP
Explanation:
2 ATP is required to get the glycolysis started. The glycolysis process is divided into two parts, the first part is called the preparatory phase in which energy is required and the second part is called the payoff phase in which energy is produced.
During the first phase in the first step during the conversion of glucose to glucose six phosphate one ATP is consumed and in the third step during the conversion of fructose 6 phosphate to fructose 1,6 biphosphate one more ATP is consumed and in the second phase, 4 ATP is produced.
Therefore the net gain is 2 ATP because 2 ATP are added to get glycolysis started.
Answer:
See explanation
Explanation:
Electroplating involves the coating of one metal on another metal. It is an electrochemical process. The positive electrode is the coating metal while the negative electrode is the metal on which the coating is to be performed.
Since copper is to be coated on an iron nail. A copper plate is made the positive electrode while the iron nail should be the negative electrode.
The electrolyte used in the process should be a copper salt e.g CuSO4 solution.
As electrolysis progresses, the copper electrode(positive electrode or anode) gradually wears away due to the fact that the copper ions are going into the solution and are being deposited on the iron nail.
