The Ureters Move Urine from the Kidneys to the Bladder.
The control variable in any experiment is designed in order to apply the same steps of the experiment but with no change happens in the observations.
In this experiment, the student tries to know the effect of solubility of different water-soluble salts (NaCl, CaCl2 and KCO3) on the melting point of the solution. All these salts dissolve in water and give some effect on the melting point except for the sand as the sand doesn't dissolve in water.
The coloration of the beetles most likely remains constant, despite differential predation, when it is strictly due to ENVIRONMENTAL factors. Phenotypic traits can be influenced by genes or the environment.
The expression of a given characteristic (i.e., a phenotypic trait) in an individual may be associated with genetic and environmental factors, as well as with the interaction between genetic and environmental factors.
Different types of environmental inputs (e.g., diet, temperature range, oxygen, humidity, light, etc) can influence a given phenotype.
A heritability value near zero (0) indicates that almost all of the phenotypic variability for a given trait is caused by environmental factors.

The circulatory helps keep you healthy because it delivers nutrients and oxygen to all of your cells(which your cells need)(and you need cells to survive).
The circulatory assists your cells and gives them what they need to stay healthy and keep you alive
Nutrients and sunlight affect a region's photosynthetic productivity.
What do you understand by photosynthetic productivity?
The rate during which energy is added to organisms as biomass (the quantity of material that makes up animals' bodies) in producers in an ecosystem is known as photosynthetic productivity, also referred to as primary productivity.
These organisms that make energy through photosynthetic processes rely on getting access to nutrients and sunlight. Photosynthetic organisms' output and efficiency can be gauged. This is known to as photosynthetic productivity (or primary productivity), and it is directly effected by the sunlight and nutrients that producers require.
