How many copies of each chromosome does each new nucleus receive during Metaphase? (onion root lab) 7th grade

Answers

Answer:

isnt it 2

Explanation:

One copy

In metaphase spindle fibers line up the chromosomes along the middle of the cell nucleus. This line is called the metaphase plate. This makes sure that in the next phase, when the chromosomes are separated, each new nucleus will receive one copy of each chromosome.

What do you predict might happen if someone introduced a new species that could eat large amounts of algae at a rapid pace, outcompeting other species already present? Describe what you think might happen, making sure to specify how at least three of the organisms that might be affected and giving a detailed explanation for each organism. Make sure to include in your answer at least one organism that does not eat algae.

Answers

Answer:

Small fish, crustaceans, and water-dwelling insects eat algae, so they are going to be affected if an new species is introduced and is water based, also the new species its the algae at a rapid pace, a bunch of organisms will be in danger because some of the organisms eats algae as a primary source of food. If there is something that can make this species go extinct for sometime until it is possible algae can grow as fast as they eat it, then there would be a bunch of sea creatures/organisms affected by this huge change. Not only will the small fish, and other sea creatures/organisms will be affected but it'll also disrupt the ocean food chain, including us human! Because we eat fish, some people depend on algae because if the algae kept getting ate up by this "new" species EVERYTHING else would be also disrupted. Microscopic animals wouldn't have enough food, fish wouldn't have enough oxygen and plants would lose some of the carbon dioxide they need to grow, so these organisms DEPEND on algae for their LIFE!

Dew point is the temperature at which the rate of condensation equals the rate of evaporation.

True
False

Answers

Answer:

Called the dew point temperature, the point of saturation is where evaporation equals condensation. Therefore, a cloud results when a block of air (called a parcel) containing water vapor has cooled below the point of saturation. Air can reach the point of saturation in a number of ways.

Explanation:

The statement "dew point is the temperature at which the rate of condensation equals the rate of evaporation" is definitely true.

What is Evaporation?

Evaporation may be characterized as a type of chemical process through which an element or compound transforms from its liquid state to its gaseous state. This can certainly be achieved by consistently delivering energy to the compound.

Dew point temperature is the temperature at which air must be cooled in order to become saturated with water vapor. This water vapor is a form of a gaseous component that intermingles with the liquid components which are formed through the process of condensation. At this point, the rate of condensation equals the rate of evaporation.

Therefore, the statement "dew point is the temperature at which the rate of condensation equals the rate of evaporation" is definitely true.

The ground retains the heat from the Sun longer than the water.

C The ground cools faster at night than the water which retains its heat warming the air above at.

Explanation:

In simple words a land breeze is the flow of wind from the land towards the sea. During the night time, the land cools down quickly as compared to the day because there is no sun to heat surrounding air and the sea surface.

describe how wind forms ocean waves in deep water and how these waves change as they develop in 6 sentences
PLEASE HELP

Answers

Wind-driven waves are created by friction between wind and surface water. When wind blows across the surface of an ocean the continual disturbance creates a wave crest. These waves can be created through local winds or distant winds. The waves can be affected by wind speed and wind duration. The faster the wind and the longer it blows, the bigger the waves. It also can depend on how far the wind blows uninterrupted.

I hope this helps :)
Wind forms ocean waves by creating friction between the wind and surface water. This creates a rising crest that forms into a wave. As the wind continues to blow, the waves also continue. Depending on the location, the waves change. For example, when deep water waves move to shallower waters, they change into breaking waves. As the wave travels into deeper waters, it slows down and the wavelength decreases.

Energy in Ecosystems
Plants capture the sun's energy and make food in the process of photosynthesis. Only about 0.1 percent of the sun's energy is captured by plants. Plants take carbon dioxide and water and, using the energy from sunlight, convert it into glucose (food) and oxygen. About one-half of the energy absorbed by plants is used right away. The other half is stored in plants as energy-containing food (carbohydrates).

Answers

A. applied force is a contact force

Answer:

A: Applied force

Explanation:

The rest of them are non-contact forces.

A contact force is any kind of force that requires contact to occur.

So:

Applied force is a contact force because they occur ONLY during contact with each other.

Gravitational force is not a contact force because they occur even when they're not in contact with each other.

Electrical force is not a contact force because they also occur even when they aren't in contact with each other.

Magnetic force is not a contact force because they pull/push on objects without touching them.

True or False. The arrow labeled A represents a transfer of solar energy to chemical energy. Explain why this is true or false.

Answers

Answer:

False. The arrow labeled C represents a transfer of carbon dioxide from factory emissions to the atmosphere, and it does not involve the conversion of chemical energy to mechanical energy. This is a chemical reaction in which carbon dioxide is released into the atmosphere.

True. The arrow labeled A represents a transfer of solar energy to chemical energy. Photosynthesis is the process by which plants convert sunlight and carbon dioxide into energy in the form of sugar molecules. This represents a conversion of solar energy into chemical energy in the form of the sugar molecules.
