List 3 differences between the cat skeleton and the human skeleton; include why the girdles are different. Connect how the differences between the skeletons will cause slight differences in how the muscle are structured.
Answer:
-Humans have 206 bones, while the average cat has about 244 bones.
-Cats have more bones in their spine than humans, to help with their movement
-The human skeleton is 20 to 25 times larger than a domestic cat
-The girdles are different because cats were made to walk on all fours so their structure has to be built differently than humans so they are able to have a range of motion.
-The difference in skeletons causes slight difference in how the muscles are structured because certain muscles are going to need to be stronger, so their will be a difference in muscle shape and size, even though they will carry out the same function.

Why do surface currents move in circular patterns?
Answer:
Ocean water moves in predictable ways along the ocean surface. Surface currents can flow for thousands of kilometers and can reach depths of hundreds of meters. These surface currents do not depend on weather; they remain unchanged even in large storms because they depend on factors that do not change.
Surface currents are created by three things:
global wind patterns
the rotation of the Earth
the shape of the ocean basins
Surface currents are extremely important because they distribute heat around the planet and are a major factor influencing climate around the globe.
Answer:
The Coriolis effect causes winds and currents to form circular patterns.

Answer:
Remove waste material, maintaining salt, pH and water balance in the body.
Explanation:
The main function of execratory system is to remove waste material, maintaining salt, pH and water balance in the body. Kidney filters the blood and removes waste material such as urea and nitrogenous waste etc, excess amount of salts and water from the body. It also maintains pH of the body by excretion of hydrogen ions as dihydrogen phosphate or ammonia from the blood and production or reabsorption of bicarbonate ions. So we can conclude that execratory system eliminates waste material, maintaining salt, pH and water balance in the body.

[Please help me with this question and please explain WHY you chose what you chose] The diagram shows a plant and an animal cell. Which is most likely true about both cells?
Both plant and animal cells use the same molecules for energy for the production of ATP (adenosine triphosphate) and glucose. Therefore, the correct statement is option B.
What is ATP?ATP is the energy currency of the cell and provides energy required for many cellular processes, such as muscle contraction, protein synthesis, etc. Both plant and animal cells produce ATP through cellular respiration, where glucose is breakdown to release energy in the form of ATP.
Glucose is a simple sugar serving as a source of energy for both plant and animal cells obtained from breakdown of complex carbohydrates in plant cells and animal cells.
However, plants can also produce energy through photosynthesis by converting light energy into chemical energy in the form of glucose. During photosynthesis, plant cells use sunlight to convert carbon dioxide and water into glucose and oxygen.
Therefore, both plant and animal cells use the same molecules for energy, primarily ATP and glucose.

Why isn’t renewable energy expanding more rapidly in the U.S.?
Answer:
Why don't we use renewable energy all the time? Unlike natural gas and coal, we can't store up wind and sunshine to use when we need to make more electricity. If the wind doesn't blow or the sun hides behind clouds, there sometimes isn't enough power for everyone.

Define the four major types of symbiosis?
Answer:
There are five main symbiotic relationships: mutualism, commensalism, predation, parasitism, and competition. To explore these relationships, let's consider a natural ecosystem such as the ocean. Oceanic environments are known for their species diversity
Explanation:
Answer:
Mutualism - An interaction between two organisms in which both organisms benefit from.
Commensalism - An interaction between two organism in which one organism benefits from and the other organism neither benefits nor gets harmed.
Parasitism - An interaction between a parasite and an organism. In this interaction the parasite lives inside of the organism and causes potential harm to the host
Mimicry - imitation of another organism for survival
Explanation:
First lets define symbiosis
Symbiosis : Interaction between two organisms predominantly to benefit one or both of the organism
Now lets find the 4 types of symbiosis
The four major symbiotic relationships include mutualism, commensalism, mimicry and parasitism
Now lets describe/define each symbiotic relationship
Mutualism - An interaction between two organisms in which both organisms benefit from.
An example would be sharks and remora fish. Remora fish keep the water fairly clear of scraps around the shark which prevents the development of unhealthy organisms resulting in a healthy shark. In return remoras receives a fairly convenient food source and they receive protection.
Commensalism - An interaction between two organism in which one organism benefits from and the other organism neither benefits nor gets harmed.
An example would be frogs and plants. Frogs use plants for protection and the plants way of life does not change in any way
Parasitism - An interaction between a parasite and an organism. In this interaction the parasite lives inside of the organism and causes potential harm
An example would be fleas and dogs. Fleas live off of the blood in the organism (the dog in this case). Consequently the dog experiences hair loss, scratching, and irritated skin.

Increased input to this cycle may be responsible for global warming.
carbon
potassium
nitrogen
phosphorus
Answer:
Carbon
Explanation:
Global warming is currently a great concern to the world. It is the process whereby the temperature of the atmosphere rises due to the effect of certain gases called GREENHOUSE GASES. Greenhouse gases are those gases that have the ability to trap and emit heat into the atmosphere e.g carbon dioxide, methane, CFC etc.
Carbon dioxide and methane, for example, are greenhouse gases that contain CARBON element in their structure. This implies that an increased input to the CARBON cycle may be responsible for global warming because more carbon input produces more carbon-based greenhouse gases, utterly leading to global warming.
The incidence of skin cancer has increased dramatically in parts of Australia where people are experiencing greater UV exposure as a result of . As the overall average temperature of Earth rises, changes in weather patterns can challenge human occupations (e.g., farming) and human health (e.g., insect-borne diseases). The term describes this overall increase in temperature, as well as the effects of this increase. In the Sahel region, south of the Sahara Desert in Africa, many nomads are losing their livelihoods and agricultural regions. The land has become essentially barren as a result of . The cost and supply of produce from the drier western United States has fluctuated because of decline in water quantity resulting from . Because of rising ocean temperature, the Great Barrier Reef off the coast of Australia is experiencing coral bleaching, which kills resources such as plants and fish populations. This ultimately leads to tremendous .
Answer:
The correct answers are:
1. stratospheric ozone depletion
2. climate change
3. desertification/land degradation
4. freshwater decline
5. biodiversity loss.
Explanation:
1) Stratospheric ozone depletion- ozone layer is the protective layer around the earth that protects us from harmful rays such as UV rays coming from the sun. There are depletions or holes in the ozone layer in some parts of Australia and therefore, therefore leading to skin cancer.
2) climatic change - The change in the average temperature or precipitation of an area that takes place due to global warming that changes the earth's climate is changing rapidly.
3) desertification or land degradation - It occurs due to past overuse of fertilizer or barren land that has zero crop yield.
4 )freshwater decline - freshwater is an essential part of the irrigation of crops in agriculture and due to the downfall of groundwater its decline the freshwater produce in these parts.
5) biodiversity loss - Coral reefs are habitats for many aquatic organisms and used as various ways of biodiversity. If there is a loss or decrease in their numbers it will affect and decline the biodiversity of the area.
