Natural selection is a fundamental mechanism driving the evolution of species. To research this conclusion a group of scientist

want to test the effects of increased river salinity on a population of catfish in a river. What results from this experiment would confirm that natural selection is a process that can drive evolution

Answer:

The result which could confirm that natural selection is a process that can drive evolution is "change in the allele frequency of the population".

When salinity of the river is increased, the individuals which can tolerate the changing environment would survive.

Due to natural selection, these individuals would survive and reproduce more efficiently as compared to the individuals which lack such traits or adaptations.

Over generations, the population would only consist of these organisms and thus, the allele frequency of the population would change.

Hence, the population would evolve.

OleMash [197]
Organisms that live in water are not totally independent of soil as a resource. These organisms depend on aquatic plants for food and other substances. These aquatic plants in turn require minerals for their sustenance. These minerals are carried to waterbodies from soil by rivers, rainwater etc.

What are the steps to construct a modern beehive​
Nikolay [14]

Answer:

go and type this you will get it

Explanation:

How to construct a modern beehive​

Hope it helps you

In traditional hives, the bees make their own wax combs that are often attached to each other, so harvesting the honey is difficult. Honey can be extracted only two or three times a year from a traditional beehive. A modern beehive produces double to triple the volume of honey compared to a traditional hive.

What is the role of electron carrier molecules in energy processing systems? why are they necessary?
natima [27]
In energy processing systems electronic carrier molecules transfer electrons from one part to other part of energy processing system. This provides the necessary energy and reduces power to carry out chemical reactions. They are necessary for aerobic cellular respiration and photosynthesis.

Different cell types can react differently to epinephrine in the human body. Choose two cell types in the human body and briefly
Ipatiy [6.2K]

Answer:

I haven't really learned about cell types but I did find this information

Explanation:

How can epinephrine have different effects on different cells? Different cells have different receptors that bind epinephrine. Different cells activate different enzymes as a result of epinephrine binding.

epinephrine induces increased vascular smooth muscle contraction, pupillary dilator muscle contraction, and intestinal sphincter muscle contraction. Other significant effects include increased heart rate, myocardial contractility, and renin release

Hope it at least helps a little :)
