Which explains what happens to a warm air mass at a cold front? A. A warm air mass overtakes a cold one, and the warm air rapidl

y rises and cools. The water in the air condenses to form clouds, heavy rain, and thunderstorms. B. A warm air mass overtakes a cold one, and the warm air gradually rises and cools. The water in the air condenses to form clouds and gentle rain. C. A cold air mass overtakes a warm one, and the cold air rapidly pushes the warm air up. The rapidly rising warm air cools, and the water in the air condenses to form clouds, heavy rain, and thunderstorms. D. A cold air mass overtakes a warm one, and the cold air gradually pushes the warm air up. The gradually rising warm air cools, and the water in the air condenses to form clouds and gentle rain.

vova2212 [387]

<u>Answer</u>: Sperm cell

<u>Explanation</u>:

Amongst all the 4 options given, only the Sperm cell is a gamete (sex cell) while all the three are somatic cells.

  • A <em>somatic</em> cell is the one which forms the body of an organism and contains all the genetic information.
  • A <em>gamete</em> is the one which is required for the purpose of fertilization. A gamete of male fuses with the gamete of female in a process called fertilization to form a zygote to give rise to a new individual.
  • A Sperm cell is basically a <em>male gamete.</em> It contains only half the amount of genetic information as the other half is contributed by the female gamete.
  • This difference in the amount of genetic information arises due to the type of cell division that occurs. The somatic cells undergo mitosis whereas a gamete requires meiosis to occur for its formation.
  • During mitosis there is a single round of cell division which divides the parent cell into two daughter cells each with the <em>complete genetic information</em>.
  • During meiosis the cell undergoes two rounds of cell division such that a total lf 4 cells are produced each <em>with half the amount of genetic material </em>as present in the parent cell.

Since, <em>sperm is a male gamete and is formed by meiosis it contains only half the genetic information as compared to the other cells.</em>

Semmy [17]

Answer:

The answer to your question is: after two hours there will be 6400 cell/ ml

Explanation:

Data

Bacteria t = 0; 400 cells/ml

generation time = 30 minutes

# cells after two hours = ?
