Describe the ocean product you researched in the "investigation: ocean products" module. What did you learn about it's connection to the ocean?
Answers
The ocean product I have researched in the "investigation: ocean products" module is petroleum. I have learnt that it can be found in layers of sediments as seen on ocean floor.
Does petroleum come from the ocean?Fossil fuels such as coal, natural gas, and that of petroleum developed under comparable conditions. Petroleum can now be discovered in huge subsurface reservoirs that were once ancient seas.
They are seen under the surface of the land or the water, there are petroleum reservoirs. Utilizing enormous drilling equipment, their crude oil is extracted.
Note that Over the course of millions of years, when the bones of dead animals and plants settle to the ocean floor, gas and oil are formed in the sea. They are buried and crushed into layers of sediment several kilometers deep on the ocean floor when combined with particles discharged from the land.

Answers
1. Using a glass when brushing teeth: By using a glass instead of leaving the tap running while brushing our teeth, we can conserve water. Freshwater is a finite resource, and reducing unnecessary water usage is essential for preserving our water supplies and ensuring their availability for both humans and the natural environment.
2. Hanging clothes: Opting to hang clothes to dry instead of using a dryer not only saves energy but also reduces greenhouse gas emissions. Clothes dryers consume a significant amount of electricity, and by utilizing natural methods like hanging clothes, we can contribute to reducing our energy consumption and lowering our carbon footprint.
3. Walking: Walking instead of using vehicles for short-distance travel offers multiple benefits. Firstly, it helps reduce air pollution by decreasing the emission of harmful gases from vehicles. Secondly, walking promotes personal health and well-being, as it is a form of physical exercise. Lastly, choosing to walk reduces traffic congestion and saves fuel.
4. Feeding stray animals: Feeding stray animals is an act of compassion and kindness. By providing food for stray animals, we help prevent their starvation and promote their overall welfare. It also reduces their need to hunt for food in natural habitats, preserving the delicate balance of local ecosystems.
5. Using the back page of paper: Utilizing both sides of a piece of paper helps reduce paper waste and conserves valuable forest resources. Paper production involves cutting down trees, and by maximizing the use of each sheet, we minimize the number of trees required to produce paper products.
6. Using a fan: Using a fan instead of an air conditioner helps reduce energy consumption and lowers greenhouse gas emissions. Air conditioners consume a significant amount of electricity, and by using fans to circulate air and provide cooling, we can contribute to conserving energy resources and mitigating the impact of climate change.
7. Watering the plants: Watering plants is essential for their growth and well-being. By providing them with adequate water, we support their ability to photosynthesize, produce oxygen, and contribute to a healthy ecosystem. Additionally, practicing responsible watering techniques, such as using watering cans instead of hoses, helps conserve water resources.
8. Sweeping: Sweeping instead of using a leaf blower or a hose to clean outdoor spaces reduces energy and water consumption. Leaf blowers and hoses consume significant amounts of electricity and water, respectively. Sweeping not only saves resources but also minimizes noise pollution and prevents soil erosion caused by high-pressure water flow.
Engaging in these activities of conserving natural resources demonstrates our commitment to environmental stewardship and sustainable living. By making conscious choices in our daily lives, we can contribute to the preservation and protection of the Earth's ecosystems for the benefit of current and future generations.

Answers
Land that gains weight will have less mass. This is an example which shows how changes in the cryosphere can affect the geosphere. Thus, the correct option is D.
What is Cryosphere?
The cryosphere comprises of an all-encompassing term for those portions of the Earth's surface where the amount of water is in the solid form, including the sea ice, lake ice, river ice, snow cover, glaciers, ice caps, ice sheets, and the frozen ground. Thus, there is a wide overlap with the hydrosphere than the other regions of the atmosphere.
All the subsystems present in the Earth interact with each other and these are found to show some changes in the cryosphere which can affect the geosphere. An example of this is the lands that gains weight will have less mass in comparison to other lands which does not gain weight.
Therefore, the correct option is D.

State the functions of the skeletal system, including the number and the major bones in the human skeleton.
Answers
The skeletal system serves several important functions in the human body. These functions include:
1. Support: The skeleton provides the structural framework for the body, giving support and shape to the organism.
2. Protection: The skeletal system protects vital organs such as the brain, spinal cord, heart, and lungs. For example, the skull protects the brain, the ribcage protects the heart and lungs, and the vertebrae protect the spinal cord.
3. Movement: Bones act as levers for muscles, enabling body movement. The skeletal system works in conjunction with the muscular system to facilitate motion.
4. Mineral storage: Bones store essential minerals, such as calcium and phosphorus, which are necessary for various body functions.
5. Blood cell production: Red and white blood cells, as well as platelets, are produced in the bone marrow, which is found in some bones.
6. Energy storage: Yellow bone marrow, found in the medullary cavity of long bones, stores energy in the form of fat.
The human skeleton consists of 206 bones in adults. Some of the major bones include:
1. Skull: Comprised of the cranium and facial bones, it protects the brain and supports the structures of the head.
2. Spine (vertebral column): Consists of 33 vertebrae, which protect the spinal cord and support the upper body.
3. Ribcage: Includes 12 pairs of ribs, the sternum, and the thoracic vertebrae, which protect the heart and lungs.
4. Humerus: The long bone in the upper arm, connecting the shoulder to the elbow.
5. Radius and Ulna: The two bones in the forearm, connecting the elbow to the wrist.
6. Femur: The long bone in the thigh, connecting the hip to the knee, and is the longest bone in the body.
7. Tibia and Fibula: The two bones in the lower leg, connecting the knee to the ankle.
8. Pelvis: A basin-shaped structure that supports the spine and organs of the lower abdomen, and connects the spine to the lower limbs.
These are just a few examples of the major bones in the human skeleton.
Answer:
Explanation:skeletal system functions are diffrent of types . In addition to defining our shape and traits as humans, it:
enables movement: Your skeleton helps you stand and move by supporting your weight. Your bodily components are movable thanks to the cooperation of joints, connective tissue, and muscles.
Bone marrow, which makes blood cells, is found in bones. The bone marrow makes RBC AND WBC
supports and shields organs: Your ribs shield your heart and lungs, your backbone shields your spine, and your skull shields your brain.
Mineral storage: Your bones are where your body stores minerals like calcium and vitamin D.

Answers
Answer:
Genetic engineering is a type of biotechnology that involves manipulating the DNA of an organism to create desired traits. This can be done through various techniques, such as gene editing or gene splicing. One benefit of genetic engineering is that it can be used to create crops that are more resistant to pests and diseases, which can increase food production and reduce the need for harmful pesticides. However, one risk of genetic engineering is that it can lead to unintended consequences, such as the creation of superweeds or the loss of biodiversity.
For society, genetic engineering can also have both benefits and risks. One benefit is that it can be used to create medicines and vaccines that are more effective and targeted, which can improve public health. However, one risk is that it can lead to unequal access to these treatments, as they may be expensive and only available to those who can afford them.
In terms of the environment, genetic engineering can also have both benefits and risks. One benefit is that it can be used to create crops that require less water or fertilizer, which can reduce the environmental impact of agriculture. However, one risk is that it can lead to the spread of genetically modified organisms (GMOs) into the wild, which can have unknown effects on ecosystems.
Overall, while genetic engineering has the potential to bring many benefits, it is important to carefully consider the risks and unintended consequences before implementing it on a large scale.
