Answer:
cardiovascular
Explanation:
Through vasodilatation or vasoconstriction in the skin heat exchanges with the outside can be regulated. For example during vasodilatation more blood flows, so the tissue will be warmer and more heat will be lost.

Explain why a lack of gravity might cause muscles to weaken
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.
What are some examples of adaptations that animals have for improving their chances of reproduction and offspring survival?
Attempt 2

What is the fossil connection between Indohyus and the whale? What is the function of this bone? Why do you think these mammals transitioned from land to water?
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:
Mutations are sudden changes that may occur in a gene or chromosome. These changes may affect the way traits are inherited. If a mutation occurs in a body cell, such as a bone cell, the mutation affects only the organism that has it. If the mutation occurs in a sex cell, then it can be passed on to an offspring. Some mutations are helpful and can be desireable in an offspring.

What are ways that pioneer species differ from climax communities? Check all that apply.
Pioneer species occur only in primary succession, while climax communities occur in both types of succession.
Pioneer species inhabit volcanic islands, while climax communities occur on continents.
Pioneer species include only one or two species, while climax communities include many species.
Pioneer species reproduce in small numbers, while climax communities reproduce in large numbers.
Pioneer species tend to be small and simple, while climax communities tend to be larger and more complex.
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.
What do you mean by the primary succession ?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.

What is the primary cause that drives the ocean conveyor belt, also referred to as thermohaline circulation?
A:Water pressure
B:Winds
C:Water density
D:Tides
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.
Once signals are processed and _______ by the central nervous system, a response is sent back to the body.
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.

Summarize Why conduction occurs in all materials but convection only occurs in liquid and gases.
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.
Explanation:
When conducting a controlled experiment why is it important to test for only one variable at a time?
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.

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.

Pollen and seeds are the most reliable play-related evidence at archaeological sites and modern day crime scenes because they are long lasting. Relate this quality to their structure and function in living plants.
plant structure plant charatrristic plant growth
Explanation:
plant structure l: their vascular tissue allow water to be absorbed in through their plant root system, up through tubes knowns as xylem and phloem and throuht ther shoot system.
plant characteristic: their most recognizable features are stems,roots, leaves, chlorophyll, chloroplasts, and cell walls, which are made of cellulose.
plant growth: two type of meristems are apical meristem and lateral meristems.
Scientists sometimes work on research to create better plants. These plants have traits that are more useful to people than are the traits found in wild plants. A scientist might start by choosing a trait to change. Then, the scientist must decide on a breeding strategy to change that trait. If the scientist chooses a good trait and a good strategy, the result might be a new and more useful plant. Imagine for a moment that you are about to start working on a similar project. Explain your self in a paragraph or 2 of no less that 5 sentences.
Question — Identify one trait of a plant that could be changed by selective breeding.
Question — Explain how the change you describe would make the plant more useful.
Answer:
question one: Things such as the size of the edible part of a plant can be increased by only pollinating the plants with the largest edible areas with the other plant with the second largest, etcetera.
question two: the plant would be more size efficient, and easier to farm for profit as less plants would be required to make the same amount of edible product, and more would be able to be produced in general

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.
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.
