Answer:
Carbon is stored in the plant, which helps a plant to grow. But when trees are cut down and burned and or allowed to rot, their basically storing carbon dioxide, which then gets released into the air ... again known as carbon dioxide. In conclusion this is how deforestation or cutting down trees and including forests can lead to and or contribute to global warming.
29. A teacher presented the two models below to the dass. The models represent a eukaryote and prokaryote cell. The teacher asked the students to label the structure of each cell that contains the genetic code and
tell where it is located.
structure C, located in the cytoplasm in Cell A and structure C, located in the cytoplasm in Cell B
structure H, located in the cytoplasm in Cell A and structure A, located in the nucleus in Cell B
structure C, located in the nucleus in Cell A and structure C, located in the cytoplasm in Cell B
structure H, located in the cytoplasm in Cell A and structure A, located in the cytoplasm in Cell B
Answer:
C. structure C, located in the nucleus in Cell A and structure C, located in the cytoplasm in Cell B
Explanation:
This question contains images that depicts an eukaryotic cell (animal) and a prokaryotic cell (bacteria). According to the question, a teacher asked the students to label the structure of each cell that contains the genetic code (DNA) and tell where it is located.
In an eukaryotic cell, the genetic material (DNA) which contains the genetic code is located inside a well defined membranous structure called NUCLEUS while the genetic material in a prokaryotic cell is found naked in a region of the cytoplasm called NUCLEOID as they lack a membrane-bound nucleus. Based on this explanation;
- Structure C is the genetic material (DNA) which contains the genetic code of cell A (eukaryotic cell), hence, the genetic code of cell A is found in structure C, which in turn is located in the centrally-placed NUCLEUS.
- Structure C is the genetic material containing the genetic code of cell B (prokaryotic cell), hence, the genetic code of cell B is found in structure C, which in turn is located in the CYTOPLASM.

2. Why does the body respond to stimuli?
3. What are some different types of stimuli?

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.
Hopefully, this helps! :D

Answer:
All of these
Explanation:
If you put all of the continents together, they fit like a puzzle. If you look at mountains and match these when they are put together, mountains will be in similar places. The fossils found in Antarctica were fossils from warm climates. That could only be if all continents used to be one!

Humans burn fossil fuels and wood, releasing carbon dioxide into the atmosphere. This carbon dioxide is then absorbed by trees for photosynthesis. These processes are contributory to which chemical cycle?
Carbon cycle controls the amount of carbon dioxide in the atmosphere. These processes are contributory to the carbon cycle in the environment.
What is a carbon cycle ?
The carbon cycle is nature's method of recycling carbon atoms, which repeatedly go from the atmosphere into Earth's living things and back into it. The majority of carbon is preserved in rocks and sediments; the remainder is preserved in the ocean, the atmosphere, and living things.
Life on Earth is reliant on the carbon cycle. The quantity of carbon that is naturally released from reservoirs is equal to the amount that is naturally absorbed by reservoirs because nature tends to maintain carbon levels in balance. This carbon balance must be preserved for the earth to continue to support life.
Therefore, the carbon cycle is an important chemical cycle.

why is the late Cambrian thought of as the period of the greatest evolutionary change in life forms on earth's history?
Answer:
The Cambrian Period marks an important point in the history of life on Earth; it is the time when most of the major groups of animals first appear in the fossil record. This event is sometimes called the "Cambrian Explosion," because of the relatively short time over which this diversity of forms appears.

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.

_____ 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.

“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).
