How dose the force of the car change as the mas of the car increases
Answer:
Increases.
Explanation:
According to Newton's Second Law of Motion:
F = ma
So, if we keep the acceleration constant:
F ∝ m
F is directly proportional to m, which means if we increase the mass, the force will also increase and vice versa.
Hence, If the mass of the car increases, Force acting on it also increases.

ICM.06] Scientific research shows that our global climate is changing as a result of an increase in greenhouse gases. Arctic sea ice is decreasing in both surface area and thickness. Which of the following statements best describes the
consequence of decreasing Arctic sea ice?
The melting of sea ice will decrease the effects of global warming in the area as the ice absorbs heat
O seawater levels wil decrease making t difficult for marine animals to survive.
Animals that rely on the sea le for survival may become extinct as their habitat disappears.
The milder temperatures will allow for greater survival rates for native species
As a result of decreasing Arctic sea ice, animals that rely on the sea level for survival may become extinct as their habitat disappears.
The increase in the atmospheric greenhouse gases means that more radiant energy from the sun that could have escaped back into space is being absorbed, leading to an increase in the global temperature.
The increase in the global temperature means that more Arctic sea ice would be melting and decreasing in size. As the ice melts, the water moves into seas thereby causing a rise in their levels.
A rise in sea level means the disappearance of coastal habitats. Thus, a loss in biodiversity will occur as the habitats of plants and animals disappear as a result of the rise in sea levels.

Answer:C
Explanation: Animals that rely on the sea lce for survival may become extinct as their habitat disappears.

if you examined a potato cell under a microscope how could you tell that it was a plant cell?
Answer:
When looking at a plant cell and an animal cell, you will notice one significant difference (though there are many more). A plant cell has one large central vacuole, whereas an animal cell has many.
Explanation:
Have a great day, and spread some positivity!
A plant cell can be identified by the presence of a cell wall, a large central vacuole, and chloroplasts.
The cell wall is a rigid structure that surrounds the cell membrane. It is made up of cellulose, a type of carbohydrate. The cell wall provides support and protection for the cell. Animal cells do not have a cell wall.
The central vacuole is a large space filled with water. It is located in the center of the cell. The central vacuole helps to maintain the cell's shape and turgor pressure. Animal cells do not have a central vacuole.
Chloroplasts are organelles that contain chlorophyll. Chlorophyll is the green pigment that allows plants to photosynthesize. Photosynthesis is the process by which plants use sunlight to convert carbon dioxide and water into oxygen and glucose. Animal cells do not have chloroplasts.
If you examined a potato cell under a microscope, you would be able to see these features. The cell wall would appear as a thin, clear layer around the cell. The central vacuole would appear as a large, empty space in the center of the cell. The chloroplasts would appear as green, oval-shaped organelles.
