Why is fishing for some kinds of ocean fish controlled by laws?

Biology
1 answer:
lora16 [44]3 years ago
8 0
C is the answer. Due to the current state of the world economy; people, if left to their own devices, would fish as much as possible so they can sell their fish to make money. Current technology means we can catch as many fish as we want (trawlers etc.). The problem with this is that there is only a finite amount of fish in the sea. If we were to fish them without limits in place, we could cause them to go extinct.

What are some possible future changes in the global climate?
Ugo [173]

The most probable future changes in the global climate are:

- Global warming;

If the levels of CO2 and methane increase enough in the atmosphere to be able to intensify the Greenhouse effect, than some portion of the ice on the planet will melt because of the rising temperatures, thus lifting up the sea level, creating more unpredictable weather with larger and stronger storms, but also making the mainland much drier. This would be a scenario if the continents are arranged like they are now, but if there isn't a sufficient mass of land on and around the poles, than all of the ice will melt and the sea levels will rise so much that the planet will come in the ''water planet'' scenario, and it will have wet tropical climate pretty much everywhere on the planet.

- Ice Age;

If there's a disruption in the warm ocean streams and some of them disappear, or the levels of nitrogen or oxygen increase in the atmosphere, the Earth will start to cool off, thus coming to a situation of an Ice Age. In this kind of situation, there will be large ice sheets on and around the poles that are stretching much further towards the lower latitudes, as well as mountains all over the world that are covered in snow and shaped by glaciers.

8. Explain how cells move large particles into the cell by endocytosis.
Deffense [45]
It is possible for large molecules to enter a cell by a process called endocytosis, where a small piece of the cell membrane wraps around the particle and is brought into the cell. If the particle is solid, endocytosis is also called phagocytosis.

The Meselson and Stahl experiment starts with E. coli containing 15N/15N labeled DNA grown in 14N media. Which result did Mesels
cricket20 [7]

Answer:

No 15N/15N labeled DNA was observed in second generation

Explanation:

Meselson and Stahl were doing an experiment to find out the semi-conservative mode of replication of DNA. The first cultured bacteria in 15N medium which was containing a heavy isotope of nitrogen. The DNA synthesized here had more density. After that they transferred the bacteria to the 14N containing medium. When bacteria reproduced and new strands of DNA were synthesized, they observed the following -

  • The first generation had hybrid DNA with 15N/14N strands
  • The second generation had both hybrid 15N/14N DNA and 14N/14N DNA strands
  • There was no 15N/15N DNA observed.

In this way they proved that one strand of DNA is kept conserved during the replication.
