1 Zinc, 2, Hydrogen, 2 Chlorine
Explanation:
Zinc, 2, Hydrogen, 2 Chlorine is a chemical reaction.
What is chemical reaction?Chemical reaction, the transformation of one or more chemicals (the reactants) into one or more distinct compounds (the products). Chemical elements or chemical compounds make up substances.
Chemical reactions are a fundamental component of life itself, as well as technology and culture. Burning fuels, smelting iron, creating glass and pottery, brewing beer, making wine, and making cheese are just a few examples of ancient processes that involved chemical reactions.
The Earth's geology, the atmosphere, the oceans, and a wide variety of intricate processes that take place in all living systems are rife with chemical reactions.

expounded by Charles Darwin and is now believed to be the main process that brings about evolution
True
False
True
The process is called natural selection and was first explored by Charles Darwin in the 19th century.
NATURAL SELECTION is the process whereby organisms better adapted to their environment tend to survive and produce more offspring. This concept was first developed by Darwin (both statements are TRUE).
Darwin referred to evolution as the process of 'descent with modification'.The main mechanism by which organisms evolve to adapt to their environments is natural selection.The theory of evolution by natural selection was developed by Darwin and it is now widely accepted as the main cause of evolution. According to Darwin, species change (evolve) over time, thereby giving rise to new species that share a common ancestor.In conclusion, NATURAL SELECTION is the process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of evolution by natural selection was first developed by Darwin (both statements are TRUE).

electrically charged particles?
A. neutrons are positive, electrons are negative
B. protons are negative, neutrons are positive
C. protons are positive, electrons are negative
Answer:
C
Explanation:
protons are positive neutrons are neutral and electrons are negative
In an electrically charged particles protons are positive and electrons are negative.
Neutron has a positive electrical charge?The charge on neutron is zero(no charge). The charge on the proton and electron are exactly the same size but opposite. The same number of protons and electrons exactly cancel one another and so atoms are neutral. Protons have positive or negative?A proton carries a positive charge and an electron carries a negative charge.so the atoms of elements are neutral, all the positive charges canceling out all the negative charges. Atoms differ from one another in the number of protons, neutrons and electrons they contain.Learn more about electrical charge here: http://brainly.brainly.com/question/1487561

Please Answer These Questions!
1. What is a stimulus?
2. Why does the body respond to stimuli?
3. What are some different types of stimuli?
4. What are sensory organs and what type of stimuli do these receptors respond to?
5. What is an explanation of how the information from stimuli is communicated to the brain?
6. What is a description of the two things that can happen when the brain processes the information from stimuli?
Hello, 3Coli Here!
Here are your answers:
1. What is a stimulus?
Stimulus is a natural body reaction caused by changes in the environment around or inside the organism. This is a response from the brain.
2. Why does the body respond to stimuli?
The body responds to stimuli, because it needs to protect itself.
3. What are some different types of stimuli?
The two main types of stimuli are external stimuli and internal stimuli. External stimuli are reactions triggered by changes that occur outside of the body, while internal stimuli are reactions triggered by changes inside of the body.
4. What are sensory organs and what type of stimuli do these receptors respond to?
The most commonly used sensory organs include Eyes, Ears, Tongue, Nose, and Skin. Eyes respond to light and motion, because they are used to see. Ears respond to sound, because they hear. The tongue is used to taste, so it senses flavors. The nose is used to smell, so it responds to scents. Finally, the skin is used to feel, so it responds to whatever it feels.
5. What is an explanation of how the information from stimuli is communicated to the brain?
Neuron receptors convert internal and external environments into electrical signals, and then is sent to the brain through nerves.
6. What is a description of the two things that can happen when the brain processes the information from stimuli?
After the brain receives the signal, it will provide a response. One type of response is that the body will physically react to the change. The second type of response is to avoid the change.

Answer:
The water is drawn in the xylem through capillary action and is dispersed through out the entire plant from stem to tips of the leaves and petals. When the water is colored, the color from the water can stain the plant, especially if it is a light colored plant, such as the white petals on our flowers.

_____ is a force caused by air that slows objects down
Answer:
Drag
Explanation:
Drag is a force caused by air that slows objects down
Friction is a major force that slows the object down, air resistance is a type of frictional force.
What is air resistance?Air resistance is a kind of frictional force that slows down an object from moving in a particular direction.
During the movement an object has a particular speed for movement, speed depends on how friction works, more friction slows the speed of an object a low friction allows the object to at a particular speed.
Air is a mixture of gases and particles in the atmosphere, these particles create a force during the movement of an object in the air, and these forces decide the actual speed of object movement.
Therefore air resistance is a force that slows the object.

“How might an energy requirement affect an individual who has a cancerous tumour?”
Answer:
Cellular respiration describes the series of steps that cells use to break down sugar and other chemicals to get the energy we need to function. Energy is stored in the bonds of glucose (like a stretched rubber band), and when glucose is broken down, much of that energy is released. Some of it is captured in a form that can be used to do work in cells - a molecule called adenosine triphosphate or ATP. The energy that is not captured in ATP is usually given off as heat (one of the things that helps us maintain our normal body temperature).

What is the function of erythrocytes?
What is the term for all the components of the blood?
What is blood?
Answer:
1. The main physiological role of red blood cells (RBCs), or erythrocytes is to transport of gases (O2, CO2) from the lung to the tissues and to maintain systemic acid/base equilibria. In addition, RBCs are well equipped with antioxidant systems, which essentially contribute to their function and integrity.
2. In humans, it includes plasma (the liquid portion), blood cells (which come in both red and white varieties), and cell fragments called platelets. Plasma is the main component of blood and consists mostly of water, with proteins, ions, nutrients, and wastes mixed in.
3.Blood is a body fluid in humans and other animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells.
