Please answer fast ASAP I give brainliest identify two other physical factors and explain their effect on the organism living in the lake?

The correct answer is - light level and temperature.

Explanation:

The structure and function of lakes are determined by various factors such as temperature, light level, wind turbulence, water flow rate, dissolved oxygen, acidity (pH), salinity, habitat size, hydrology, and water depth. Stratification and water circulations are influenced by temperature and wind turbulence.

Light level is an important abiotic factor in lake ecosystems. Light is an essential part for plants to perform photosynthesis. Light can directly affect how much life you find in a given area depends on the production of energy and food by the aquatic plants by photosynthesis.

Temperature is a similarly important factor for lakes or other aquatic organisms as it is for land animals. each organism is able to survive in specific temperature ranges and their metabolic activity also depends on the specific temperature range.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
