The negatively charged oxygen atoms in our air are attracted to the positively charged copper atoms in the penny. When oxygen binds with copper, they form a new molecule known as copper oxide. This is why most pennies you see look dirty or tarnished, it's actually copper oxide. Silver will not oxidize as quickly, as it is not made of a material that negatively charged oxygen atoms are attracted to.

Explain why asexual reproduction produces offspring that are identical to the originals, and sexual reproduction produces offspring that are unique from their originals.
Answers
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.

Once signals are processed and _______ by the central nervous system, a response is sent back to the body.
Answers
Answer:
interpreted
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.
How are signals processed ?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.

Explain why a lack of gravity might cause muscles to weaken
Answers
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.

Camilo and his parents travel to Yellowstone National Park for a vacation. They read that below Yellowstone National Park lies a supervolcano that is responsible for small earthquakes and hotspot activity in the area.
The convection of hot rock transfers heat throughout Yellowstone National Park. This heat transfer causes geysers and hot springs to form. Explain the process of convection that rock in the mantle of Earth undergoes.
Answers
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.

Summarize Why conduction occurs in all materials but convection only occurs in liquid and gases.
Answers
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.

When conducting a controlled experiment why is it important to test for only one variable at a time?
Answers
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.
