Answer:

A psychrometer is a simple type of hygrometer. A hygrometer is an instrument which is used for measuring the humidity in an environment.

A psychrometer is a device which uses the difference in readings between a wet-bulb thermometer a dry bulb for measuring the relative humidity.

The bulb that is wet will cool by evaporation to the "dew point". Comparing this wet bulb to the dry bulb (the general air temperature) on a comparative chart will yield the approximate relative humidity.

What might hershy and chase have concluded if they had found 35s instead of 35p in bacterial cells? Explain your answer
kaheart [24]

Hershey and chase have concluded that DNA is not protein it was the genetic material.

Explanation:

Hershey and chase said that DNA is not protein it was the genetic material. They took a direct physical approach in finding the genetic material. They both determined that a protective coat was formed around the bacteriophage.

The internal DNA is not a protein, a genetic material. They used label to find it. The lack of 32p labeled DNA remaining in solution after bacteriohages are allowed to absorb the bacteria showed tha DNA was transferred into the bacterial cell.

The radioactive 35s in the solution shows that protein coat protects the DNA before adsorption.

Most of the nucleated cells in a multicellular organism contain all of the genetic information for the organism. Which of the fo
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>
