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.

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

“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).

explain reproduction in hydra
Answer:
Budding
Explanation:
The common asexual method of reproduction by hydras is budding. Buds originate at the junction of the stalk and gastric regions. The bud begins as a hemispherical outpouching that eventually elongates, becomes cylindrical, and develops tentacles. The bud then pinches off and a new individual becomes independent. Buds are produced every two to three days under favorable conditions. Following unfavorable conditions, such as injuries or periods of scarce resources, hydras occasionally reproduce through transverse and longitudinal fission.

A bird that can easily out complete other birds for its food and that can produce many eggs has high what?
Answer:
Fitness or aptitude
Explanation:
Aptitude (or fitness) is the genotype/phenotype that results in the survival, fertility, and capability of having a mate. It is a way of measuring the individual ability to leave fertile offspring.
Aptitude puts together everything that matters in natural selection. Includes the survival capability, finding a mate partner possibility, producing fertile descendants, and leaving the genes to the next generation. The aptitude of a genotype must be significant for natural selection to act in its favor.

Bobcats are generally solitary and establish territories of a certain size where they hunt for food. What type of population dispersion would you expect bobcats to have?
Answer:
Uniform dispersion.
Explanation:
The bobcats' population distribution would be a uniform dispersion because they are distributed in an area in a balanced way. That is to say, that there is space between them and that each bobcat establishes its personal space when hunting and for their daily life. As they are solitary animals, they do not live in groups and only associate with other bobcats to reproduce themselves.

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.
