Answer:
<em>The correct option is B) the birthrate increased</em>
Explanation:
The picture simply shows that after a period of 10 years, the population of the prairie dogs increased.
Carrying capacity can be described as the maximum number of individuals of a species that a particular habitat can hold. As the diagram shows, there are no factors showing that the carrying capacity of the particular habitat has increased. Hence, other statements like statement D is false.
Answer:
humans had more developed 'social' brains than Neanderthals, which enabled us to colonize new habitats and adapt to climate fluctuations
Explanation:
A more developed brain is considered to be an adaptive advantage that enabled early humans to leave Africa and colonize new habitats. Modern humans are able to adjust to new environments, situations, and socialize with other humans because the brain is a social organ. Although Neanderthals were able to occupy an important area of Europe, H. sapiens could colonize faraway lands, migrating into tropical forests, deserts, and glacial lands (colder areas than those colonized by Neanderthals). These early humans formed social groups which enabled them to find food more easily, thus greatly increasing their chances for survival.
Answer:
Explanation:
Science (genetics, molecular biology, genomics) genes or gene products that are homologous (descended from a common ancestor) and are found in separate species due only to the speciation event (not to gene duplication).
The epiglottis
The cartilage in the throat that guards the entrance to the trachea and prevents fluid and food from entering it when a person swallows is known as the epiglottis
.
The epiglottis is an elastic flap located at the upper end of the larynx in the throat. The epiglottis is the valve that turns passage to either the esophagus or the trachea. The epiglottis allows air to enter the airway to the lungs during breathing, and during swallowing, it allows food and fluids to pass into the gastrointestinal tract.
Answer:
Dry air.
Explanation:
One definition of dry air is a theoretical sample of air that has no water vapor. Another definition of dry air is air that has a low relative humidity. When the relative humidity drops below about 40%, the air feels dry to the skin.
