Describe the ocean product you researched in the "investigation: ocean products" module. What did you learn about it's connection to the ocean?

Answers

The ocean product I have researched in the "investigation: ocean products" module is petroleum. I have learnt that it can be found in layers of sediments as seen on ocean floor.

Does petroleum come from the ocean?

Fossil fuels such as coal, natural gas, and that of petroleum developed under comparable conditions. Petroleum can now be discovered in huge subsurface reservoirs that were once ancient seas.

They are seen under the surface of the land or the water, there are petroleum reservoirs. Utilizing enormous drilling equipment, their crude oil is extracted.

Note that Over the course of millions of years, when the bones of dead animals and plants settle to the ocean floor, gas and oil are formed in the sea. They are buried and crushed into layers of sediment several kilometers deep on the ocean floor when combined with particles discharged from the land.

What is the skeletal system?

The skeletal system provides the support and protection for the internal organs and gives muscles the point of attachment. Humans have an endoskeleton, where bones lie underneath skin and the muscles. In other animals, like insects, with an exoskeleton on outside of the body.

The humerus is the largest bone in the body. The cranium is the part of skull which encloses the brain. It is also called as the braincase, it is the intimate relation to the sense organs.

The clavicle is the collarbone, which is one of the most fractured bones in the body. The carpal bones are bones of the wrist, it connect the distal aspects of the radial and ulnar bones of forearm.

The patella is the largest sesamoid bone in the human body and is located anterior to knee joint within the tendon of the quadriceps muscle that provides an attachment point for both quadriceps tendon and the patellar ligament.

DNA replication begins when the double helix untwists and breaks in half between the nitrogen bases. What are the next two steps in the process of DNA replication?

Answers

Answer:

Step 1: Before DNA can be replicated, the double stranded molecule must be “unzipped” into two single strands. ... Step 2: Primer Binding. The leading strand is the simplest to replicate. ... Step 3: Elongation. ... Step 4: Termination

The DNA gets unzipped during DNA replication after the double helix unwinds. Each original DNA strand acts as a template for the new strands when the strands are split in two. The bases on either half of DNA are then paired with the nitrogen bases that have sugar and phosphate. In order to adhere to the principle of base pairing and guarantee that the base sequence is maintained, the molecules present in the new strand must be complementary to those found in the original strand. DNA replication ends with the formation of two identical strands.

There would be meat that had tumbled out on the floor, in the dirt and sawdust, where the workers had tramped [walked heavily] and spit uncounted billions of consumption [tuberculosis] germs. There would be meat stored in great piles in rooms; and the water from leaky roofs would drip over it, and thousands of rats would race about on it. It was too dark in these storage places to see well, but a man could run his hand over these piles of meat and sweep off handfuls of the dried dung of rats. These rats were nuisances, and the packers would put poisoned bread out for them; they would die, and then rats, bread, and meat would go into the hoppers [containers] together.This is no fairy story and no joke; the meat would be shoveled into carts, and the man who did the shoveling would not trouble to lift out a rat even when he saw onethere were things that went into the sausage in comparison with which a poisoned rat was a tidbit [small piece of food].
