Compare the two processes: mitosis and meiosis. Can you identify the the true statements about the two? Meiosis results in four haploid daughter cells. Mitosis results in four diploid daughter cells. In both processes, DNA replication must occur. During meiosis the 2N mother cells produces N daughter cells. Mitosis is responsible for genetic continuity; in higher organisms it is essential for growth and repair. In plants, egg and sperm are produced via mitosis. I’m

Answer 1
Answer:

Answer:

The correct statements are:

  • Meiosis results in four haploid daughter cells.  
  • During meiosis, the 2N mother cells produce N daughter cells.  
  • In both processes, DNA replication must occur.  
  • Mitosis is responsible for genetic continuity; in higher organisms, it is essential for growth and repair.  

Mitosis is a type of cell division in which a parent cell is divided into two identical daughter cells. Each daughter cell contains identical genetic material as that of the parent cell.  

It plays important role in growth and repair of cells and tissues in multi-cellular organisms.

Meiosis is a type of cell division in which a parent cell is divided to produce four daughter cells. Each daughter cell contains exactly half the genetic material (chromosomes) as that of parent cells

It plays important role in the production of gametes (eggs and sperms) in sexually reproducing organisms.

Before either cell division, the DNA is replicated in the S or synthesis phase of the cell cycle.

Fill the cup two-thirds of the way with water. Add a few drops of blue food coloring to make your “ocean.”
Pour 1/3 cup of oil into the ocean.


Answer the following questions:
What happens to the oil when you first pour it in?

we know that oil floats on water and do not mix

What happens to the oil when you first pour it in? It flows into the water, but then seperates.

Why does this happen? oil is lighter than water and the molecules of the oil are attracted to the other oil molecules, not water, the water molecules the same

What kinds of animals would be most affected by an oil spill at the beginning? animals that live their lives near the surface of the ocean. Why? because now the water that was clear and free-flowing is now dark and sticky. oil also changes the way how some animals survive so make their ways less effective. one example are birds like pelicans

Use a spoon to stir the oil for 30 seconds.


Answer the following questions:
What natural action stirs the real ocean? ocean currents caused by wind and the earth's roation
What happened to the oil? went back to the top
Even if you can’t see it, is all the oil still in your ocean? yes
Which animals in the ocean become affected after wave and currentaction causes some of the oil to settle to the bottom, or be absorbedinto the water?  bottom-feeders
Add a splash of dish detergent to the mixture and stir.


Answer the following questions:
What happened to the oil? it mixed with the water Is it all still in the ocean? yes
Sometimes cleanup efforts involve dumping a soap mixture over a spill area. Why is this done? to bond the oil to the detergent and the detergent to the water. so they can grab all the oil
What might be a negative effect of dumping the soap?
soap has chemicals that could upset the ballance of the ecosystem and kil some animals/plants

One function of the immune system is to attack the foreign cells to protect the body. In organ transplants, the body recognizes that the new organ is made of foreign cells. What kind of medicine would you give a patient to increase the chances of transplant success?

Answers

The kind of medicine that is given to increase chances of transplant success is called anti-rejection medicine or immunosuppressant drugs.These are a class of drugs that reduce or suppress the strength of the body's immune system . Their primary function is to lower the body's ability to reject a transplanted organ such as liver, heart or kidney.By weakening the immune system, immunosuppressant drugs decrease the body's reaction to the foreign organ. The drugs allow the transplanted organ to remain healthy and free from damage.

Medicine that makes the immune system less effective.
