The oldest fossils and evidence of modern humans on earth are around 200,000 years old. Before that time lived the ancestors of modern humans and Neanderthals. If all of earth’s history was compressed into 12 hours, what time would you first see modern humans?
Answer:
I would say around the 11th or 12th hour
Explanation:
seeing as the question calls for ALL of earth's history compressed into 12 hours the timeline should be similar to this: Earth was born at midnight, at around 2-3 AM land masses form, Right after that, life begins, For around 8 hours (11 PM) life is confined in water, right after that we have plants, 22 minutes later we have dinosaurs, 22 minutes later we have mammals, 5 minutes later dinosaurs are extinct, 6 minutes later we have people. So it's most likely the 12th hour. I hope this helps.

An ecosystem is defined as
Answer:
Ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life. It contains biotic or living, parts, as well as abiotic factors, or nonliving parts.
An ecosystem is defined as a location where a bubble of life is created by the interaction of plants, animals, and other species with the weather, topography, and other factors.
What is topography?Topography is defined as the investigation of surface characteristics and shapes. In order to describe the shape of the terrain, topographic features are particular points, lines, and areas that correspond to local differential qualities of the surface of the terrain.
A self-sustaining unit of living creatures (plants, animals, and decomposers) and their non-living surroundings is called an ecosystem (air, water and soil). Examples: Aquatic plants and animals that dwell in pond water make up the aquatic portion of an ecosystem known as a pond. A biome is a group of associated ecosystems.
Thus, an ecosystem is defined as a location where a bubble of life is created by the interaction of plants, animals, and other species with the weather, topography, and other factors.

Describe the impact deforestation can have on species inhabiting those affected environment
Answer:
In heavily deforested areas, soil erosion and nutrient runoff are common after a rainfall. Soil erosion tends to be greater in drier, more mountainous areas, where there is less vegetation to prevent the movement of soil and to absorb the nutrients
Explanation:
Answer:
The soil that provides nutrients for vegetation in ecosystems is also affected by deforestation. ... Some of the carbon dioxide released into the atmosphere comes from dead vegetation that decomposes in the ground. In heavily deforested areas, soil erosion and nutrient runoff are common after a rainfall.

List examples of organisms from the movie that represent each of the six kingdoms. Monera (Archaebacteria/Eubacteria): Protista: Fungi: Plantae: Animalia:
(finding nemo)
Examples of kingdom monera may include blue-green algae - Cyanobacteria and E.coli. Archaea includes halophiles and methanogens.
What do you mean by Kingdom?Kingdom may be defined as the second highest taxonomic rank, just below the domain. Kingdoms are divided into smaller groups called phyla. It is a taxonomic rank that is composed of smaller groups called phyla.
Examples of kingdom Protista may include Amoeba, paramecium, and euglena. Examples of the kingdom Fungi may include yeasts, molds, mushrooms, puffballs, and smuts. Kingdom Plantae includes green, brown, and red algae, liverworts, mosses, ferns, and seed plants with or without flowers.
While the kingdom Animalia is a diverse kingdom that includes invertebrates like snails and sea anemones, and vertebrates like humans and dolphins. They range in size from microscopic rotifers to 100-foot-long blue whales.
Therefore, examples of each kingdom may be significantly mentioned above distinctively.

Use your knowledge of gravity to explain why it makes sense that Jupiter has more moons than Earth. In your response be sure to:
a. compare the masses of Earth and Jupiter.
b. discuss the role of gravity in the orbital motion of objects in space.
The size of Jupiter is much larger than Earth, meaning it's gravitational pull is stronger. The mass of Jupiter is 318 times bigger than Earth. In order to calculate the gravitational force between two objects with masses of m1 and m2 , the equation is: where G is the gravitational constant (6.67E-11 m3 s-2 kg-1), r is the distance between the two objects, and F is the magnitude of the force between the objects.Every object in space exerts a gravitational pull on every other, and so gravity influences the paths taken by everything traveling through space. It is the glue that holds together entire galaxies. It keeps planets in orbit. It makes it possible to use human-made satellites and to go to and return from the Moon.
