Facts Avout Cells???

Facts avout cells???

 

Cells have been the center of study since their discovery by Robert Hooke in the cork he observed under a simple microscope. Listed below are some facts about cells.

  • Cells are the basic unit of life. Life is said to exist or have existed as long as a cell is observed in it.
  • A group of cells is called a tissue. Tissues are cells that perform the same kind of function to increase efficiency. If you group up tissues together they become organs.
  • Cells can only come from preexisting cell. This is one of the three postulates of cell theory. No cell can form from a nonliving thing. This is what debunked the long believed theory of spontaneous generation.
  • Cells can be infected by bacteria, another kind of cell, or a virus, which is a nonliving genetic material-protein complex which can hijack the cells mechanism.
  • Animal cells and plant cells are not the same. They have different components like plants having cell wall while only animal cells have centrioles.
  • A cell can be haploid (N) or diploid (2N). All somatic or body cells are diploid; they contain complete set of chromosomes. On the other hand, gametes or sex cells are haploid; they contain half the set of chromosomes. This is necessary to avoid duplication of chromosomes when fertilization occurs.

What Is A Tropical Storm?

What is a tropical storm?   A tropical storm is a spiral mass of strong and fast-moving winds that has a low-pressure center. It gains its energy from the convection that happens within it. The mass of clouds in a tropical storm can bring heavy rain and thunder. A tropical storm starts when a low-pressure area forms above the surface of the ocean. The low-pressure area is caused by the heat of the sun. This produces convection currents which swirl the mass of winds as the circulation between rising hot air and sinking cold air continues. This generates rotational energy until it continues to become a huge spiraling mass of winds. A tropical storm can be called by different names depending on where it is formed, namely tropical cyclone, typhoon , and hurricane . In the Philippines, it is called a typhoon. On the other hand, in the United States, it is called a hurricane . For more information about tropical storm, you may click the links below: brainly.ph/question/2140147 brainly.

Sue Scored A Total Of 35 Points In Two Games. She Scored 6 Times As Many Points In The Second Game As In The First. How Many More Points Did She Score

Sue scored a total of 35 points in two games. She scored 6 times as many points in the second game as in the first. How many more points did she score in the second game   Answer: 30 points Step-by-step explanation: Let x be the number of points she scored in the first game. Therefore, your equation will be: x + 6x = 35. Solving for x: x + 6x = 35 7x = 35 x = 35/7 x = 5 Since the second game is 6x, therefore 6(5) = 30 points. Hope this helps! ~~DeanGD20
