A sample of DNA contains 120 nucleotides, if 35 nucleotides are Guanine, how many nucleotides are Thymine?
Vitek1552 [10]

Answer:

25

Explanation:

In DNA, Guanine pairs with Cytosine, and Thymine pairs with Adenine. This tells us that there are equal numbers for each Guanine and Cytosine, and Thymine and Adenine. When there's 35 Guanine, there should be 35 Cytosine that goes with it. 120 - 2(35) = 50. The remaining 50 nucleotides are Thymine and Adenine, and since they are the same number, divide 50 by 2. 50 ÷ 2 = 25. There are 25 thymine in the sample of DNA.

Why is it important for both eukaryotic and prokaryotic cells to go through cell division?
Naya [18.7K]

Answer:

La división celular es una parte muy importante del ciclo celular en la que una célula inicial se divide para formar células hijas.1​Debido a la división celular se produce el crecimiento de los seres vivos. En los organismos pluricelulares este crecimiento se produce gracias al desarrollo de los tejidos y en los seres unicelulares mediante la reproducción asexual.

Los seres pluricelulares reemplazan su dotación celular gracias a la división celular y suele estar asociada con la diferenciación celular. En algunos animales la división celular se detiene en algún momento y las células acaban envejeciendo. Las células senescentes se deterioran y mueren debido al envejecimiento del cuerpo. Las células dejan de dividirse porque los telómeros se vuelven cada vez más cortos en cada división y no pueden proteger a los cromosomas como tal.

Las células hijas de las divisiones celulares, en el desarrollo temprano embrionario, contribuyen de forma desigual a la generación de los tejidos adultos.

1. Why is diffusion insufficient to meet the oxygen requirements of multicellular organisms like humans?
astraxan [27]

1.   The oxygen requirements of an animal cannot be met by the process of     diffusion as diffusion is a very slow process. To overcome this, multicellular organisms have specialized cells and tissues for performing various necessary functions of the body such as intake of oxygen and food.

2.   What criteria do we use to decide whether something is alive? Any visible movement such as walking, breathing, or growing is generally used to decide whether something is alive or not. However, a living organism can also have movements, which are not visible to the naked eye.

3.   An organism uses outside raw materials mostly in the form of food and oxygen. The raw materials required by an organism can be quite varied depending on the complexity of the organism and its environment.

4.   The various processes essential for maintaining life are nutrition, respiration, transportation, excretion, control and coordination.

here it is hope it helps you out...
