What color would the bby and water turn with plants in the dark
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.

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.

“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.

Santos and Lüderitz are the same distance from the equator, and both cities are near the ocean. The air temperature in Lüderitz is colder than the air temperature in Santos. What causes the air temperature in these places to be different? Explain what causes the difference as completely as you can.
Answer:
The Ocean Currents.
Explanation:
if you look at a current map, you'll see warm currents near Sanots and cold ones near Lüderitz. Therefore, the air in Sanots is a lot warmer and the air in Lüderitz is colder.
The phenomenon of the ocean current is responsible for this deviation of air temperature between two places.
What do you mean by Air temperature?Air temperature may be defined as the temperature of the surrounding air of organisms including humans.
The ocean water captures the heat from the sunlight and increases the temperature of the ocean. This heat is then entranced through ocean circulation and increases the temperature of the air as well as the atmosphere.
The air temperature in Luderitz is colder because the ocean of this region receives less sunlight in low intensity which results in less heat captured by the ocean and makes the air a little bit colder than that of Santos oceans.
Therefore, it is well described above.

This molecule provides stability to the phospholipid bilayer and without it the membrane would easily fall apart.
Answer:
The correct answer is - cholesterol molecules.
Explanation:
Cholesterol molecules are the molecules that acts as a bidirectional regulator for the lipid bilayer as it provides fluidity by raising the melting point of the membrane at high temperature and stabilize the membrane.
On the other hand, it also prevents the membrane from clustering or being tough or stiff by intercalates between the phospholipids at low temperatures. Therefore it is the molecule that provides stability to the membrane.
The process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully
expounded by Charles Darwin and is now believed to be the main process that brings about evolution

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.

After a devastating forest fire, the surrounding area contained no life. After some time, small plants began to grow along the remaining soil.
Answer:
Yes.
Explanation:
Yes, small plants began to grow along the remaining soil because of the presence of seeds in the soil that sense suitable environmental condition and come out of the soil. The ashes of burn trees have huge amount of nutrients in the form of minerals that triggers the growth of small plants. After the destruction of forest, new plants grow on that land, this type of phenomenon is called ecological succession.
Answer: CORRECT (SELECTED)
Secondary succession
Explanation:
Secondary succession occurs when a previously occupied area is recolonized after a disturbance kills most, or all, of its community.

What is Convection current?Convection currents are defined as the result of differential heating where lighter, less dense, warmer materials rise while heavier, more dense, cooler materials sink. This is the movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the Earth's mantle.
Convection currents arise from differences in fluid density that arise due to a temperature gradient, resulting from the continuous replacement of the hot fluid in the region of the heat source with the nearby cold fluid which is known as the natural convection currents.
Thus, Radiogenic heat released- Cause: convection currents cycle through magma.
