In rats, offspring of larger mothers tend to be larger than offspring of smaller mothers, even when fed the same diet and raised
apart from their mothers. When fed higher calorie diets, rats tend to be larger than rats fed lower calorie diets, even when they are offspring of the same mother. These two experimental results suggest that rat body size is influenced by which factors
The correct answer would be - environmental and genetic (allelic) factors.
Explanation:
The phenotype of an animal can be manipulated or affected by the change in gene expression through environmental factors. Environmental factors can be temperature, diet, oxygen level, light, and many other abiotic factors. In this case, diet is affecting the phenotype of the rats that eat high-calorie diets.
Genetic or allelic factors are also expressed in this case as the size of the rats also depends on the size of the mother rat which means that there are some genes also carry these traits
we can track climate patterns back to us on earth and the excessive use of fossil fuels and other gasses contribute to this - its basically proven that we are the reason climate change is a thing. climate will change by itself by us humans are causing this to be much faster than it should be
Chargaff's rules state that DNA from any species of any organism should have a 1:1 stoichiometric ratio of purine and pyrimidine bases, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine.
