Answer:
Because their offspring cannot breed, they are considered separate species.
Members of the same species that produce offspring can continue passing on their genes through their offsprings offspring and so on and so forth

Explanation:
Answer:
Chemical digestion
Mechanical digestion can only break up the food particles into smaller pieces. A chemical digestion process called enzymatic hydrolysis can break the bonds holding the molecular 'building blocks' within the food together. For example, proteins are broken down into their 'building block' amino acids.

The formula for potential energy is decided by mass, height, and gravity.
Increasing the height of the object is directly proportional to increasing potential energy.
Answer:
A) Light pollution both attracts and repels migratory birds
In addition to the many hazards that exist in urban areas, cities typically lack the food resources and cover that birds need during migration or when raising their young. ... Darkening skies at night during migration season makes it easier for birds to navigate.
Explanation:
Migration carries high costs in predation and mortality, including from hunting by humans, and is driven primarily by availability of food. It occurs mainly in the northern hemisphere, where birds are funneled on to specific routes by natural barriers such as the Mediterranean Sea or the Caribbean Sea.
The question is incomplete as it does not have the options which are:
You would see disruptive selection.
The relative numbers of flower colors would remain unchanged.
The relative numbers of white flowers would increase.
Your results would show directional selection.
Answer:
Your results would show directional selection
Explanation:
In the given question, the pea plants produce a range of flower color from white to pink and then dark pink. If we will grow the plants with dark pink flowers than the plants in that area will have dark pink flowers.
In evolutionary terms, this can be suggested that the growing the plants with by humans is a natural force that is favoring the extreme color of the flower which is dark pink and natural selection will be observed.
In this scenario, since the dark pink color is the extreme color which is favored by the humans to grow therefore the directional way of natural selection is acting which is characterized by the favor of only one extreme phenotype.
Thus, the selected option is correct.
