Answer:
Mostly crows, robins, and jays were the first of a few bird species impacted by the West Nile Virus when it was detected.
No, there were over 300 species discovered to be affected by the virus, these were just the main ones to be impacted.
Answer:
Cyanobacteria or blue-green algae are found in the following places:
- Freshwater (rivers, lake, ponds, streams and hot springs)
- Marine (seas, oceans)
- Soil
Explanation:
Cyanobacteria:
Cyanobacteria or blue-green algae are photosynthetic prokaryotes that inhabit a wide range of habitats. They are found as free-floating plankton in marine and freshwater environments or attached to rock surfaces as mats and periphyton (biofilm).
Cyanobacteria can either be unicellular or filamentous. They are resilient microorganisms that can inhabit the most harsh environments on Earth. Apart from the aforementioned habitats, cyanobacteria are also found in hot springs, desert soil and saline lakes.
They provide information on shared ancestry and evolutionary relationships.
Allele frequency<span>, or </span>gene frequency<span>, is the relative frequency of an </span>allele<span> (variant of a </span>gene<span>) at a particular </span>locus<span> in a </span>population, expressed as a fraction or percentage.<span>Specifically, it is the fraction of all chromosomes in the population that carry that allele. </span>Microevolution<span> is the change in allele frequencies that occurs over time within a population .</span>
The answer is C. El Niño would cause changes in the genetic makeup of organisms.
