Answer:
The correct answer is "grass -> grasshopper -> raccoon -> wolf"
Explanation:
Food chains are diagrams that represent the order at which organisms feed from each other, starting from producers that are able to make their own food, until quaternary consumers that feed from predators. In this case, the sequence of grass -> grasshopper -> raccoon -> wolf can be found in the meadow. Grass is a plant that function as producer, which is consumed by grasshopper (primary consumer), which is consumed by raccoon (secondary consumer), which is consumed by wolf (tertiary consumers). I attached the missing information in a picture.
Answer:
<u><em>Genetic variation</em></u> occurs because beneficial traits exist in a collection of genes, and <u><em>gene flow</em></u> makes these traits more prevalent in populations.
Explanation:
In biology, genetic variation can be described as the different genotypes which occur in species of the same kind. This genetic variation allows those organisms to survive on Earth which are better adapted to survive to the environmental changes.
The organisms which are better adapted to live in an environment will reproduce and pass their traits to the offsprings. Over time, these traits will become more prevalent in a population.
Answer:
An atom's electronegativity gets higher as you move up in the periodic table. Thus, the atoms in the top right have the highest electronegativities and the atoms in the bottom left have the lowest ones.
