In spite of flowers, these trees bear needles annually.
Moreover, conifers are very adaptive trees that can grow in very cold and dry climate zones.
It is due to their adaptability that they can survive all year long without losing a life.
Siberian fir, Dahurian, and Siberian larches are examples of confer forests.

Explanation:
Hershey and Chase's experiment was performed to test whether DNA serves as the genetic material or protein.
To perform experiment they grew bacteriophage into radiolabeled phosphorus and sulfur compounds. The phosphorus is an integral part of the structure of DNA whereas proteins contain sulfur in their structure.
In the given condition if radiolabeled nitrogen is utilized then the experiment will fail as the structure of proteins also contains an amino group( NH₂) in their structure as well as DNA. The scientist will not be able to identify whether the DNA is the genetic material or protein.
Thus, option-E is the correct answer.
A) Some members of the Euglenoids lose their photosynthetic pigment when left in Dark : TRUE
B )The loss of photosynthetic pigment in Euglenids stored in the dark is permanent : False
<h3>What are Euglenas</h3>
Euglenas are unicellular organisms belonging to the kingdom Protista, when kept in the dark for too long Euglenoids begin to lose their chlorophyll. As it loses its chlorophyll it becomes unable to produce its own food and starts consuming bacterias within its habitat.
The loss of chlorophyll in Euglenids can be regained after it is been exposed to sunlight and allowed to grow exponentially for several weeks.
Hence we can conclude that Some members of the Euglenoids lose their photosynthetic pigment when left in Dark : TRUE while The loss of photosynthetic pigment in Euglenids stored in the dark is permanent : False
