Explanation:
It's kinda hard to answer without the scenarios present.Wait nvm
1. the greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without its atmosphere.The greenhouse effect occurs naturally. Lately the greenhouse effect has been magnified due to greenhouse gases emitted into the atmosphere by humans. and global warming is a gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants.Global warming refers to the increase in annual average temperatures across the globe. As the amount of greenhouse gases in the atmosphere increases, the planet becomes warmer and warmer on average.
2. atmospheric carbon dioxide acts as a thermostat in regulating the temperature of Earth

Section 1: Experimental Overview
1. What is the purpose of the lab, the importance of the topic, and the question you are trying to
answer?
Answer:
The ball with less density will sink and the higher density one will rise
The importance of the lab in this topic is to find how dense an object is, and if it can sink or float, and it is important to answer the question so you can find the mass and volume.
My hypothesis for this experiment was that the ball with less density will sink and the higher density one will rise.
The methods that I used to test my hypothesis were dropping the ball/marble into the thing of water.
Explanation:
It tells you if your hypothesis was incorrect or correct from the data.
The data supports this because you tested and got your results correctly which will help you to form a hypothesis.
If I could repeat the lab and make it better... I would make it where every mistake I've made, and improve it. If we didn't do this, the lab would be a mess and wouldn't be successful.
If a person is nearsighted, what type of lens will their glasses have to correct their eyesight?
converging lens
diverging lens
flat lens
A concave lens is called a diverging lens In concave lens, spherical surfaces are recessed inwards.
It is thinned out in the middle.
When parallel beam of light is passed through concave lens, light rays spread out to different directions.
Hence, a concave lens is called a diverging lens.
Nearsightedness (myopia) is corrected with lenses called “minus power lenses.” They are concave-shaped and help the eyes focus light properly. Myopia causes a person to see distant objects as blurry. Prescription eyeglasses or contact lenses can usually correct this blurry distant vision.
The focusing power of an eye with myopia is stronger than a normal eye. It brings light to a focal point in front of the retina, instead of on the retina.
A lens used to correct myopia works by reducing the focusing power of the eye. This is why it is called a "minus power lens" (or "minus lens").
Minus lenses are concave in shape. In other words, they are thinnest at the center and thicker at the edge. This lens shape moves the focus of light from in front of the retina directly onto its surface. This shift corrects the blurry distance vision caused by nearsightedness.
The power of a lens that corrects myopia is measured in units called diopters (D). The lens powers on an eyeglass prescription for myopia always begin with a minus sign. The higher the power number of the lens, the more myopia it corrects.
For example, a -6.00 D lens corrects twice the amount of nearsightedness as a -3.00 D lens.
High-index lenses are typically recommended for correcting nearsightedness greater than -3.00 diopters. They are thinner and lighter than regular plastic lenses, so they are more attractive and comfortable.
Answer:
Its actually concave lenses
Explanation:
As someone who wears glasses, there are different lenses or 'levels' of eyesight that requires a personalized prescription.

• home to many types of grazers
• experience all seasons of weather
• home to bison
• home to the African elephant
• example: tallgrass prairies of North America
• example: Serengeti in Tanzania
• also known as tropical grasslands
• few trees due to little rainfall
1)
(Savannas)
(Both Types of
Grasslands)
(Temperate
Grasslands)
Answer:
S - Savannas are typically found in tropical or subtropical regions.
S - Savannas tend to have more trees and shrubs.
S - Savanna's climate is drier than that of a grassland.
G - Grasslands are found in temperature regions.
G - Temperature Grasslands are mainly devoid of trees, receive less rainfall than Savannas & endure broader temperature extremes.
G - Grasslands make up 25 percent of the Earth's land surface and dominate in regions with limited rainfall, which prevents forest growth. This results from nearby mountain ranges that cause rain shadows over adjacent open-range lands.
B - Both represent the world's richest and most diverse ecosystems. They both provide a home for a quarter of the world's population and a habitat for thousands of plants and animals.
B - Many species gather in vast numbers, graze on the varied grasses, and can be found nowhere else on Earth. The coexistence between wildlife and grasses is key to healthy ecosystems. Animal migrations regenerate the landscapes, by controlling pests, dispersing seeds, and trampling invasive species. Through this partnership, grasslands and savannahs generate vital benefits for both people and nature.
B - Ecosystems such as these two in specific are essential for climate mitigation – they store carbon, locking it deep in the soil and extensive root systems. They are the source of or support many of the world’s biggest rivers and wetlands, ensure food security, support livelihoods, and are embedded in the cultural identity of millions of people.

The picture shows a Single-celled organism that has a nucleus and organelles, lacks a cell wall, and obtains food by eating other organisms. The organism also has cilia that it uses to move through water. Which kingdom should this organism be classified?
Science
Protista
Protists are single-celled and usually move by cilia, flagella, or by amoeboid mechanisms. There is usually no cell wall, although some forms may have a cell wall. They have organelles including a nucleus and may have chloroplasts, so some will be green and others won't be. They are small, although many are big enough to be recognized in a dissecting microscope or even with a magnifying glass. Nutrients are acquired by photosynthesis, ingestion of other organisms, or both.

If I were a predator bird I would find summer easier to hunt. This is because in summer all the animals are not hiding in their homes or resting.
What do you mean by predators?A predator is an organism that eats another organism. The prey is the organism which the predator eats. Some examples of predator and prey are lion and zebra, bear and fish, and fox and rabbit.
Predation is a biological interaction where one organism, the predator, kills and eats another organism, its prey. It is one of a family of common feeding behaviours that includes parasitism and micropredation and parasitoidism.
Predation involves four steps: search, recognition, capture, and handling. The possibility of co-evolution of predator and prey operates at each of these steps. Predators search the environment for acceptable prey.

The hardest question ever: What is truth?
State the functions of the skeletal system, including the number and the major bones in the human skeleton.
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.
