Explanation:
DNA is the unit of heredity as it contains the genetic code of an organism which is carried all the genetic information and transfer from the parent cell to the daughter cell. It also carries the information required for making all essential proteins in an organism.
So, if an organism did not have DNA, it would be missing the information system which is also responsible for the cell division other than given information.

Answer:
Temperature and precipitation.
Explanation:
Climate is defined as long-term climate patterns in a location. Looking at average temperature and precipitation through time is the simplest way to characterize the climate.
Temperature and precipitation are the two most significant factors in the climate of a place. Obviously, the annual average area temperature is significant, but the annual temperature range is important as well. Some locations range from the highest to the lowest temperature significantly wider than others. Average precipitation is very essential, but the annual change in precipitation is equally important. Some regions experience approximately the same precipitation year-round. For half of the year, other locations have very low precipitation while the other portion of the year has lots of precipitation.
Abiotic factors determine which organisms can survive in an ecosystem because they are the non living objects in an ecosystem
