The carbon cycle works in conjunction with Water cycle. Therefore, option A is correct.
The exchange of carbon between the Earth's biosphere, pedosphere, geosphere, hydrosphere, and atmosphere occurs through the carbon cycle, a biogeochemical process. Both biological substances and many minerals, including limestone, mostly consist of carbon.
Respiration, combustion, decomposition, and photosynthesis. Carbon enters plants and other living things through the atmosphere. Carbon dioxide, for instance, is a contaminant in the atmosphere.
The carbon cycle describes how carbon moves among various "carbon reservoirs" (or "carbon sinks") that are present on Earth. It is essential for preserving our planet's carbon balance and stable temperature. The carbon cycle controls carbon naturally, which is essential for life on Earth. The Earth would be frozen without it.
Thus, option A is correct.

Answer: Water Cycle
Explanation:
food storage; deciduous.
b. chrysophyta
c. phaeophtya
d. rhodophyta
a tumor–like growth
a hemorrhage
2. When a virus invades the body, some B cells recognize it as nonself and produce plasma cells that release a substance to kill the virus. What is this substance called?
antigen
antibody
pathogen
3. Which of the following forms blood clots?
fibrin
macrophages
thrombin
4. An antigen has invaded a mammal's body. Specific immune cells engulf and ingest it. Some of the digested pieces are displayed on the cells' bodies. What happens next?
B cells are activated and release antibodies.
T cells are activated and produce clones.
B cells withdraw the immune response as the antigen is killed.
The conditions described by Mike all point to an inflammation, not a tumor-like growth or hemorrhage. When a body is invaded by a virus, B cells produce antibodies to destroy it. Fibrin is responsible for blood clot formation. When pieces of a digested antigen are displayed on a cell's body, it prompts T cells to activate and produce clones.
1. Mike's knee injury which revealed a red, swollen, and warmer area than the surrounding indicates an inflammation. This is a protective response to injury or destruction of tissues which serves to destroy, dilute, or wall off the injurious agent and the injured tissue.
2. When a virus invades the body, some B cells recognize it as foreign and produce plasma cells that release a substance to kill the virus. This substance is referred to as an antibody.
3. Fibrin is responsible for the formation of blood clots. It is a fibrous protein that helps control bleeding and forms a meshwork at a wound site, creating a clot to prevent further bleeding.
4. When an antigen invades a mammal's body, specific immune cells engulf and digest it. The digest pieces are displayed on the cells' bodies leading to the activation of T cells which then produce clones.

When the body senses that the heart rate is very high, it secretes hormones that decrease the heart rate.
When a pregnant woman begins to go into labor, the body sends hormones that increase the intensity of the labor contractions.
When someone is exercising intensely, the body sends hormones that increase oxygen supply for cellular respiration.
Answer;
An example of positive feedback loop is;
-When a pregnant woman begins to go into labor, the body sends hormones that increase the intensity of the labor contractions.
Explanation;
-Feedback loops are therefore the process whereby a change to the system results in an alarm which will trigger a certain result. The result will then either increase the change to the system or reduce it to bring the system back to normal.
-Feedback loops are important because they allow living organisms to maintain homeostasis (maintenance of internal environment of the body constant).
-A positive feedback loop occurs in nature when the product of a reaction leads to an increase in that reaction. It moves a system further away from the target of equilibrium, by amplifying the effects of a product or event and occurs when something needs to happen quickly.
A positive feedback loop in biology is a process in which the end product of an action stimulates more of the same action to occur. An example is during child birth, where hormone release intensifies labor contractions, leading to further hormone release. This continues until the process is complete, differentiating from negative feedback loops which work to maintain homeostasis by reversing a process.
A positive feedback loop in biological systems is a process in which the end products of an action cause more of that action to occur. This contrast with a negative feedback loop, which works to stop a process in order to bring the body back to its set point. One of the examples provided is a classic example of a positive feedback loop: when a pregnant woman begins to go into labor, the body sends hormones that increase the intensity of the labor contractions.
This is a positive feedback loop because the contractions that begin labor lead to the release of a hormone (oxytocin) that intensifies those contractions, which then causes more hormones to be released, and so on until the baby is born.
Other instances, such as when blood sugar is low or the heart rate is high, are illustrations of negative feedback loops, where the body works to maintain homeostasis by reversing a process.

Answer: "The synovial fluid in my joint capsule acts as a lubricant and helps the movement of the joint's articulating surfaces."
Explanation:
Synovial fluid is also called Synovia. It is produced by the synovial membrane. It is a thick liquid found in the cavities of synovial joints. It's function is to reduce friction by acting as a natural lubricant between the articular cartilage of synovial joints and allows ease of movement, they act as shock absorber and nourishment in the joints. Each of the joints contain synovial fluid.

Explanation:
Enzymes don't take part in a reaction but just speeds up a reaction
