Answer:
b i had that before its b
Explanation:
Answer:
The correct answer would be - the ratio of phenotypes in an organism cross will tell if the genes are linked or not.
Explanation:
In this question, we perform a test cross with a fruit fly that is heterozygous If we perform a test cross between two parents with identical heterozygous genomes AaBb.
If there is no recombination found in the offspring of this cross it means there are no linkage of genes present. And if there are new or recombinant phenotypes present it means that there are genes linked together.
Answer: A. Water must be available for plants to transpire and the air cannot be saturated with humidity.
Explanation:
Evapotranspiration is the sum of evaporation and transpiration. Evaporation is the loss of water from the earth surface or ground water table and transpiration is lost of water from plant surfaces. Plant absorps water from the soil through the root and it is transport by xylem to various body cells.
When the humidity is high and the air is saturated with water the rate of evapotranspiration is low but at a low humidity the rate of evaporation is high until the air is saturated.
Temperature also have a major role in transpiration. When the temperature is high the plant stomata is open which favours water Loss from plant but when the temperature is low plant closes their stomata in response to temperature change.
Answer:
codon
Explanation:
A codon is a sequence of three DNA or RNA nucleotides that corresponds with a specific amino acid or stop signal during protein synthesis.
