Answer:
Your circulatory system carries oxygen, water, and nutrients to cells throughout your body. Wastes from the cells are eliminated by your respiratory system, your excretory system, and your skin. Your nervous system controls all these activities with electrical impulses.
a solid produced in a solution during a chemical reaction?
Answer:
a solid produced in a chemical reaction in a solution is known as precipitate.
Explanation:
precipitates are solids deposited in the bottom during a chemical reaction.
A solid produced in a solution during a chemical reaction is called a precipitate. Precipitates are formed when two or more reactants are combined and the precipitate settles down below.
In a precipitation reaction, the soild particles settle down below while the soluble partcicles remain inside of the solution. Precipitation reactions are widely used in various fields, such as environmental analysis, chemical reactions, etc. For example, in a reaction in which silver nitrate (AgNO₃) solution is mixed with sodium chloride (NaCl), the precipitate is silver chloride and settles down below.

As a person exercises, this causes several body systems to work together. For 2 points each, answer the following questions: 1. Define organ system and what they are made up of to be able to do specific functions 2. Identify TWO organ systems (other than the nervous system) that would be involved in exercise. 3. Explain how the NERVOUS system would be involved in the exercise.
Answer:
The parasympathetic nervous system conserves energy as it slows down heart rate, increases intestinal and glandular activity, and relaxes the sphincter muscles of the gastrointestinal tract. It gets the nickname "rest and digest" for doing exactly so. Typically most active when sleeping, however is also the explanation for post-prandial fatigue, or being tired after eating (especially a large meal).
Explanation:
Define organ system and what they are made up of to be able to do specific functions An organ system is made of a few organs that perform multiple functions.
Identify TWO organ systems (other than the nervous system) that would be involved in exercise. parasympathetic nervous system
Explain how the NERVOUS system would be involved in the exercise.The peripheral system allows the brain and spinal cord to receive and send information to other areas of the body, which allows us to react to stimuli in our environment.The peripheral nervous system itself is divided into two parts: the somatic nervous system and the autonomic nervous system.Each of these components plays a critical role in how the peripheral nervous system operates.
Motor neurons: Also called efferent neurons, motor neurons carry information from the brain and spinal cord to muscle fibers throughout the body. These motor neurons allow us to take physical action in response to stimuli in the environment.
Sensory neurons: Also called afferent neurons, sensory neurons carry information from the nerves to the central nervous system. It is these sensory neurons that allow us to take in sensory information and send it to the brain and spinal cord.

How do swim bladders help fish go up and down in water?
Answer:
The trick is the swim bladder, which is basically like an air-inflated balloon that can expand and contract depending on how much gas is inside. When the swim bladder expands it will increase in volume and therefore displace more water. This increases the fish's buoyancy and it will float upward.

Question
Brown tree snakes are an invasive species causing huge environmental and financial damage in Guam. In June 2000, researchers captured 504 brown tree snakes on Guam's Andersen Air Force Base. On average, the snakes weighed 121g and ranged from 23 to 663 g at capture. From this information, we conclude that the distribution of brown tree snake masses (that is weights) must be
A) roughly symmetric
B) left-skewed, have a low outlier, or both
C) right-skewed, have a high outlier, or both
D) multimodal (multiple peaked)
Answer:
The correct answer is C)
From the information provided, the distribution of the brown tree snake masses is right-skewed, has a high outlier, or both.
Explanation:
In statistics, after evaluating data and representing it on a graph, it can show a normal distribution. A graph that is normally distributed has the mean (average), median, and mode to be all equal.
In some cases, the distributions skews to the left or to the right.
A right-skewed distribution happens when most data represented graphically are expressed on the right, or positive side, of the graph's peak.
A high outlier refers to a value from a set of data that falls or "lies outside" most of the other values in that set of data. That is, it much smaller or larger than most of the data within its set. For example:
3, 4, 6, 2, 3, 6, 98, 1, 1, 2
In the number array above, 98 would be the outlier.
From the question above, it is very easy to see that the distance between the average and the highest possible weight of one snake is large.
Average is given at 121g
The largest occurring weight is given at 663g
The difference is 542.

PLEASE ANSWER FAST - A student attached two balloons to equal lengths of string and tied them to the same point. The student observed that the balloons repelled each other, as shown in the diagram below. In terms of electrical charges, explain why the balloons repelled each other
Answer:
The balloons repelled each other because they both are electrically charged.
electrically charged object produces electrostatic force . Two electrically charged object repels each other . So both balloons are charged
The balloons repelled from each other because they both are electrically charged and as we know electrically charged object produces electrostatic force, they repels each other .
what is electrostatic force ?The electrostatic force attraction or repulsion is defined as the force exists between two charged particles which is also known as Coulomb’s interaction or force, the atom's stability can be maintained by the electrostatic force between protons and electrons.
For example, a balloon is rubbed with human hairs and come close to another balloon, so they stick together, Lightning due to electrostatic force, ironing a silk , it clings to the body due to electrostatic force.
Coulomb’s Force can be applied to perform magic tricks, Photocopiers, Electrostatic air filters, Ink-jet and laser printers

Data from embyros can be used to help establish evolutionary relationships. True or false
Answer:
True
Explanation:
The study of the formation and development of the embryo is very useful in evolutionary biology in order to determine similarities derived from a common ancestor (i.e. homologies). In consequence, embryology is a discipline used to establish relationships between species and higher taxa. For example, vestigial organs and/or tissues (e.g., tails in humans) can be observed in the embryos during the first stages of development. In this regard, embryology has been an important aspect of the evolutionary theory proposed by Darwin (1859) by evidencing the process of species radiation from their ancient ancestors.
