Answer:

The Earth is hotter at the center and cooler at the surface. Convection occurs when cooler, denser  magma near the surface sinks back toward the core. Warmer, less dense magma near the core is displaced upward toward the surface.

At Yellowstone, there is a hotspot where the crust is thinner and the magma comes closer to the surface.

Explanation:

Once signals are processed and integrated by the central nervous system, a response is sent back to the body. The central nervous system includes the brain and the spinal cord, and it receives and processes information from the peripheral nervous system, which includes all the nerves in the body outside of the brain and spinal cord.

After the signals are processed, the central nervous system sends a response back to the body through the motor neurons of the peripheral nervous system, which carry signals from the central nervous system to the muscles and glands. This response could be a conscious or unconscious action, such as moving a muscle, secreting a hormone, or regulating the heartbeat.

To further elaborate, the process of the nervous system receiving and processing information from the environment, integrating it, and producing a response is known as the "reflex arc."

The reflex arc is a rapid and automatic process that occurs without conscious thought, and it is designed to protect the body from potential harm. For example, if you touch a hot stove, the nerve endings in your skin will detect the heat and send a signal to the spinal cord.

The spinal cord will then process this information and immediately send a signal back through the motor neurons to your muscles, causing your hand to quickly pull away from the stove. This entire process occurs within a fraction of a second and without conscious thought, helping to prevent further damage to your hand.

Overall, the central nervous system plays a crucial role in the body's ability to sense and respond to the environment. Through the integration of information from the peripheral nervous system and the production of responses through the motor neurons, the central nervous system helps to regulate and maintain the body's internal environment and protect it from potential harm.

Answer:

Water Density

Explanation:

There is constant motion in the ocean in the form of a global ocean conveyor belt. This motion is caused by a combination of thermohaline currents (thermo = temperature; haline = salinity) in the deep ocean and wind-driven currents on the surface.

Answer:

Indohyus is a fossil, found in 2007, of a chevrotain-like mammal believed by some paleontologists in the Evil Liberal Science Conspiracy to be a transitional form between land-dwelling mammals and the ancestor of whales.

The origin of cetaceans from land-living mammals is among the most famous of these events. Much earlier, during the Mesozoic Era, many reptile groups also moved from land to wate

Explanation:

Answer:

Convection only happens with fluids, materials that can flow. Liquids can flow (think of water) and gases can flow (think of wind). Solids are stuck in place so they can't flow and since they can't flow, there is no convection. The way heat transfers through solids is conduction.

Answer:

Lack of gravity causes you to use less work to move your muscles.

Explanation:

If on Earth your arm weighs 3 pounds, the muscle will only have to move 3 pounds of force. For example, if you were to go on the moon, your arm would have the same mass but there would be less gravity pulling it dow. So now your muscles only need to pull 1 pound. Over extended periods, you would be working less, thus not using your muscles to fullest potential and in result you would get weaker.

The lion eats the deer. So the lion is the predator and the prey is the deer

Answer:

The lion

Explanation:

Predators are hunting other animals.

Answer:

The offspring of an organism that produces asexually is identical to its parents because in asexual reproduction there is no mate required, so therefore the one parent produces and passes its genetic information down to its offspring. Sexual reproduction is common in mammals they produce with a mate, so the offspring has a combination of both of the parents traits and has more genetic variation.

Sexual reproduction:

the production of new living organisms by combining genetic information from two individuals of different types (sexes). In most higher organisms, one sex (male) produces a small motile gamete which travels to fuse with a larger stationary gamete produced by the other (female).

asexual reproduction:

Asexual reproduction is a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes. The offspring that arise by asexual reproduction from either unicellular or multicellular organisms inherit the full set of genes of their single parent.

Pioneer species occur only in primary succession, while climax communities occur in both types of succession.

Pioneer species include only one or two species, while climax communities include many species.

Pioneer species tend to be small and simple, while climax communities tend to be larger and more complex.

Pioneer species only exist in primary succession, but climax communities occur in both primary and secondary succession. This is the first way that pioneer species and climax communities vary from one another.

A new environment developing, such as a glacier melting or a freshly created volcanic island, is known as primary succession. The process of an established ecosystem recovering following a disturbance, such as a forest fire, is known as secondary succession.

Adapted to the hard circumstances of a freshly established ecosystem, pioneer species are the first creatures to populate a new habitat.

Contrarily, climax communities are the outcome of succession and are made up of a variety of species that have evolved to survive in the more consistent circumstances of an established habitat.

Explanation:

Answer:

Explanation:A variable within a scientific experiment is something that is changed (i.e. it varies). There should be only one  manipulated variable within a scientific experiment so that the experimenter can be certain it is this variable which causes a pattern in the resultant data, if any exists at all. If there were multiple variables, then the experimenter would not know what accounted for the results of the experiment.  

For example, say an experimenter was testing the respiration rate of goldfish. He had three goldfish each in five different tanks. He increased the salt concentration in each tank by one tablespoon. He increased the temperature within each tank by intervals of ten degrees. All the fish in tank five die. Becuase the scientist changed more than one variable, he is not able to determine if the death of the fish was due to the high salt concentration or high temperature.
