A convincing explanation of why some lineages survived while others vanished is still lacking in the hypothesis of an asteroid impact as the cause of the end-cretaceous mass extinction.

<h3>What is an asteroid?</h3>

One of the smaller planets in the inner Solar System is an asteroid. Asteroids are metallic or rocky bodies without an atmosphere, ranging in size from 1-meter pebbles to a dwarf planet with a diameter of over 1000 km.

The majority of the one million or more known asteroids are concentrated in the main asteroid belt, which is 2 to 4 AU from the Sun and between the orbits of Mars and Jupiter. The three categories of asteroids that are typically recognized are C-type, M-type, and S-type.

These were given their names and are frequently associated with, respectively, carbonaceous, metallic, and silicaceous compositions. The largest asteroid, Ceres, has a diameter of over 1,000 km (600 mi), making it a dwarf planet.

Which is not a process involved in the formation of sedimentary rock? depositing cementing eroding cooling

andreyandreev [35.5K]

Sedimentary rock is one of the three main rock groups (along with igneous and metamorphic rocks) and is formed in four main ways: by the deposition of the weathered remains of other rocks (known as 'clastic' sedimentary rocks); by the accumulation and the consolidation of sediments; by the deposition of the results of biogenic activity; and by precipitation from solution.

The study of the evolution of behavior, emphasizing the role of ecological factors as agents of natural selection is known as be

Andrej [43]

Answer:

b. True

Explanation:

Behavioral ecology is a science that studies animal behavior, considering its evolutionary and ecological bases, in which through experiments it seeks ways to show the evolutionary / adaptive causes of behaviors. Ecoetology deals with functional questions about behavior, how a behavioral pattern contributes to the survival chances of an animal or group of animals and their reproductive success. In addition, behavioral ecology is a meeting point for the study of behavior, ecology and evolution, in which ecology is the stage on which the animal must perform its behavior, and evolution in which organisms will be selected for having higher behaviors. success.

For this reason, we can conclude that the study of behavioral evolution, emphasizing the role of ecological factors as agents of natural selection, is known as behavioral ecology.
