State three things you do each day that affect the environment around you. Explain how the things you do affect the environment around you.
Answer:
Driving or using cars as a method of transportation increases the amount of Co2 released into the atmosphere. Due to this the environment becomes less and less unstable. Another daily thing I do every day that effects the environment is throwing away trash. As our trash fills the landfills some of them can be picked up by birds or even end up getting blown into the ocean. However, recycling is one positive aspect in our every day lives. When we recycle companies and factories are able to reuse things we no longer use. Because of this we are able to protect many ecosystems and the environment.

How does the process of ridge push cause the formation of new oceans?
Answer:
Explanation and answer below
Explanation:
Ridge push causes a rift valley; as the plates move apart, a new ocean basin forms, filling with water and eventually becoming a mature ocean. Ridge push causes a convergent plate boundary; as the plates move together, new islands form, which “trap” water between them, causing an ocean to form.

The picture shows a contractile vacuole of a unicellular freshwater organism. The contractile vacuole regulates the flow of water into and out of the cell in an aquatic environement. What condtions cause the contracile vacuole to fill with water? Your answer: The concentration of water is greater outside the cell than inside the cell. The concentration of water inside the cell is the same as the concentration outside the cell. The temperature of water in the vacuole is higher than the temperature of its environment.
Answer:
The concentration of water is greater outside the cell than inside the cell.
Explanation:
In living cells, water moves by Osmosis across the cell membrane, which acts as the semi-permeable membrane. Osmosis is the movement of water molecules from a region of high water concentration (low solute concentration) to a region of low water concentration (high solute concentration).
The contractile vacuole of this freshwater organism helps regulate water intake and exit by storing excess water. According to osmotic flow, water will flow into the organism via its cell membrane (semi-permeable membrane) because the concentration of water outside the cell is high than inside the cell, hence, this causes an osmotic gradient causing water to flow into the cell. The water that flows into the cell is stored in the Contractile vacuole.

The atmospheric temperature decreases when snow starts melting because the snow
melt
Answer:
The atmospheric temperature decreases when snow starts melting because the snow absorbs thermal energy from the atmosphere to melt.
Explanation:
The temperature of the air, the intensity of the sun, the speed of the wind, and the amount of humidity are the factors that influence the melting of the snow. The thermal energy in the atmosphere is absorbed by the snow because the temperature of snow is less than the temperature of the atmosphere. When the flow of temperature takes place, the energy also flows. The thermal energy helps the snow to melt because the snow requires warmth to melt.

8. Ligaments are strips of tough tissue that
support soft tissues inside bones
prevent friction between bones
connect bones to bones
attach muscles to bones
Answer: C
Explanation:
Ligaments are strips of tough tissues that serves as connective tissue for two or more bones and cartilages. These also holds the joints together.
Ligaments are strips of tough tissue that connect bones to bones; that is the third option because the bones that are present in the body are connected to each other with the help of the ligaments.
What is the significance of the ligament?Ligaments are significant for many different factors, such as that they have an important role in physical activities such as sports and maintain optimal performance and injury prevention as they have a rich blood supply. They have an important role in preventing injuries to joints and bones as they protect bones and cartilage from excessive stress and connect bones to bones.

What are Darwin's Finches?Charles Darwin observed a group of small sparrow like black birds with strong, short beaks which are known today as Darwin's finches. These finches varied on different islands, but they were closely related to one another.
These finches evolved from a common ancestors to have different beaks well suited for different types of food they feed on. Generally long and pointed beaks are suitable for seed and cactus feeders. Even some short beaked finches tear up the base of the cactus and feed on its pulp.
The slender and sharp beaks are common in insect eating finches. The process by which they successfully evolved and radiated to different habitats is called the adaptive radiation.
