Answer: Option D.
Genotype by environment interaction.
Explanation:
Genotype by environment interaction refer to a situation where two different genotypes react differently in an environment. Light skinned humans are at greater risk of skin cancer because they lack melanin which the dark people have and this melanin protect the skin from sun.
All the choices are correct. Differences in the norm of reaction I.e they react different way.
Epistasis is when the effect of a gene suppress the other.
Pleiotrophy is when a gene influence another genes phenotipically. These are all genotype enviromr interaction.
<span>Forensic investigators observe the crime scene and gather any physical evidence that is found and document the analysis done on them. Sketches and the photos taken at the crime scene are also the part of the evidence they collect. Since here the bloodstains found by the Forensic investigators are less than 1mm diameter, they can deduce the weapon used for crime would be shotgun as it has a narrow barrel.</span>
Answer: It becomes more dense when it freezes.
Explanation: water becomes less dense when it freezes because ice has a cage like structure.
Answer:
The answer is A.
Explanation:
The example experiment given in the question would be a valid experiment because there is more than one variable.
For an experiment to be valid, there have to be a dependent variable, an independent variable, a constant and a control aspect.
In the example, we can say that the independent variable which has the direct effect on the aspect that we are looking for, the freezing point, is the amount of salt in the water. Therefore the dependent variable is the freezing point which is the part being observed for any change. The constant can be the amount of water used because it is static and the control can be the temperature the mixtures are exposed to which does not change throughout the experiment.
Therefore the answer is option A.
I hope this anwer helps.
The answer is A.
Water, oxygen, and chemical energy are required and ATP is changed to ADP.
Hope this helps :)
